Science Fair Food Projects – Some More Mold – Growing A Fungus Garden

Magriet — Tue, 27 Apr 2010 12:26:56 +0000

When we think of science fair food projects, most of us probably think of the bread mold science fair project that has been done to death already. Well, here is one of our science fair food projects that look at more than only the fungus that grows on bread. There is still going to be bread in the mix though as we are going to grow a “fungus” garden.

Do you know why we can call it a fungus “garden?” Yes, because a fungus is a “plant” and it needs certain conditions to grow such as food, the same as all other kinds of “plants.” Keep in mind though that they are microorganisms and that the microbes are only visible when a lot of them gather together. This is what we normally call mold. Now we are going to see how many of them we can grow in our fungus “garden.”

For a good science fair project you have to make notes of all your steps, saying what you are doing and why you are doing it. You must formulate a hypothesis, and do the experiment according to the correct scientific method and think of your display. It is always a good idea to take photos as you go.

Because fungus can be harmful, do not take it to the fair, but take enough photos to use in your display. Make sure you show the different kinds of fungus clearly.

What you need for this experiment:

2 Empty clean and completely dry mayonnaise or other suitable jars with a lids
2 Pieces of bread
2 Pieces of apple
2 Pieces of cucumber
2 Pieces of cheese
2 Pieces of carrot
2 Pieces of any other kind of fruit available
A little water
A pen
A notebook
A camera

How to do your experiment:

First of all formulate your hypothesis. It is that if the food is left undisturbed in the jar for some time, the food will rot and create a colorful fungus “garden.”
Place one piece of all the food in one of the jars. Make sure you do not overfill the jar so that you will be able to see the fungus growing clearly.
Now you have to sprinkle a little water in the jar and make sure you moisten all the food, do not soak it though.
Do you know why you are doing this?
Close the jar with the lid
Place the jar on a counter top where it will not be disturbed and also out of direct sunlight.
Now you do exactly the same with the second jar except you do not sprinkle any water on it.
This jar will serve as your control and every time you observe the other jar and take photos of it, you have to do it with this jar as well.
It is important that you now observe the changes that happen in the jar everyday.
Record everything you see and take photos every day.
Keep this up for at least two weeks and then ask an adult to dispose of the jar and it’s contents.

Now you have to formulate your results:

How long did it take before you noticed the first fungus growing?
How many different types of fungi were you able to grow in your fungus “garden?”
Could you see more than one type of fungi growing on one kind of food?
Did the fungi spread over time?
Did the food change in shape or texture as the fungi grow?
Did the fungi grow more on certain kinds of food than on others?
Did the fungi grow slower or faster in your control jar?
Remember, every step of the way, you have to make the same observations and take the same photos of your control jar as of the other jar
Make sure you show the difference in the two jars very clearly

A Fun Science Experiment

Magriet — Tue, 20 Apr 2010 11:04:15 +0000

Apart from doing science fair projects, simply doing science experiments for the fun is a good idea as well. Especially

If your water is too dark you cannot see the layers properly. Make the water light.

homeschoolers must make an effort to do as many fun and easy science experiments to instill a love of science in the kids.

Today’s experiment fall in that class. If you are looking for a science fair projects, I can recommend 24 Hour Science Projects where you will find complete projects you can do in 24 hours or less. So, go to 24 Hours Science Projects now!

Our fun experiment today will show how different layers of liquid can be formed in a jar because of the difference in density of the liquids.

What you will need for your science experiment:

A glass half filled with water
4 tablespoons of vegetable oil
4tablespoon of golden syrup
Food coloring
A clean glass jar

How to do your science experiment:

Color the water in the glass with a little food coloring. Do not make it too dark or you will not be able to distinguish the layers very well. Your layers will also not stay very long as the water with the food coloring will start coloring the syrup as it dissolves in the water. (It practically “soaks up” the colored water, do you know why?)
In a clean glass your spoon four tablespoons of vegetable oil
Slowly add four tablespoons of the colored water to the jar.
What happens?
Now you add the four tablespoons of golden syrup to the jar very carefully and watch what happens.
What do you think will happen if you add the liquids in a different order?
Why do you see three layers?
Why is the syrup at the bottom and the oil on the top?

Science Project – More About Pollution – Polluting A Pond Or Lake

Magriet — Tue, 13 Apr 2010 11:15:18 +0000

When you go camping you may think it is fine to wash your clothes and dishes in a pond or lake, but is it the case? Are you polluting it or not? Detergent is supposed to clean, so what does it do to a pond or a lake? For all the info on how to do a good science project as well as examples of projects you can do in 24 hours or less go to: 24 Hour Science projects.

So, to start this science project, formulate your hypothesis. Is the detergent in the lake or pond polluting the water in the pond? Will it have any negative effect on the life on and inside the pond?

What you need for this Science Project:

A plastic bag
A large bowl of water
Liquid detergent
Wax paper
Fastener or staples
A camera for your photos

How to do this Science Project:

Stuff the plastic bag with the wax paper.
Close the bag with the fastener or the staples
For fun draw a duck on it to represent one of the species on the lake or pond
Let your “duck” float on the water in the bowl
Now you add a little detergent to the bowl of water
What happens?
Do you know why it happens?
What is the reason a duck stays afloat and dry in the water?
What changed when you added the detergent to the water?
So, do you think it is a good idea to wash dishes and clothes in a pond or lake?

Explanation:

Just as the oil on a ducks feathers the plastic and wax paper is water repellent, which means the water does not stick to it.

The detergent though, enables the water to stick to greasy materials. This then allows the water to cling to your plastic “duck” and a real ducks feathers making it impossible for the duck to stay dry and afloat.

Plants Releasing Water Science Fair Project

Magriet — Tue, 30 Mar 2010 13:59:08 +0000

Where does all the water go that a plant absorbs? Do plants release water? This is the start of this very easy science fair project that is suitable for very small kids. Your purpose is to show that the water the plants absorb from the ground is finally released again. For more top science projects that can be done in a short period of time I can recommend 24 Hour Science projects.

What you need for your plants releasing water science fair project:

One small, healthy potted plant
A clear plastic bag
Some tape or string
A note book
A pencil
A camera for your photos
Water

How to do your experiment:

Start by watering the plant thoroughly
Now you place the plastic bag over the green leafy part of the plant and secure it around the stem with your tape or string.
Make very sure that you do not damage the plant
Now you place the plant in a sunny spot
Check on your plant every hour, make notes of what you see and take photos for your display
What happens?
Why do you think it happens?

Explanation:

The leaves of the plant have tiny openings called stomata in them, mostly at the bottom of the leaves. When the plant produces food it takes in air from the stomata and then it releases the air again as well. In the same way water is also released form these stomata. This is the water vapor you see condensation on the inside of the plastic bag in the form of droplets.

It is this process that is the reason for the high humidity in a jungle.

Of course, the amount of water a plant releases will depend on the weather conditions as well as the size and shape of the leaves.

Find our exactly how you have to do a top science fair project by having a look at 24 Hour Science Projects. All the projects can be done in 24 hours or less. So, if you do not have any time any more 24 Hour Science Projects may help you out.

Fill each of the bags with dry beans
Mark them A and B
A will be your control (what is that? Find out in 24 Hour Science projects)
Fill bag B with as much water as possible
Seal both the bags very well
Place them on your tray
Place the tray outside in a sunny location

What happens?

Now you to observe your beans for a few hours
Make meticulous notes and take some photos for your display
After a few hours you will notice that the beans in the bag with the water start to swell
After some more time they will swell so much that the bag will pop open and the beans will spill out

Why does this happen?

What can your conclusion be?

Was your hypothesis correct?

When you are doing this science fair project about starting the growing process, it does not matter if your hypothesis was correct or not. What is important is that you have followed the correct scientific method and arrived at a conclusion that proves what you set out to prove.

Wind Erosion Science Fair Project

Magriet — Mon, 01 Mar 2010 13:37:18 +0000

It is possible to do a good High School Science Fair Project On Air Pollution. There is an easy way to do one for little kids as well; using more or less the same method you can do a wind erosion science project. Wind erosion is another major problem in many parts of the world and it is good to see how bad it is in your vicinity.

For a good science fair project you have to make sure you use the correct scientific method. In a good ebook such as Super Science Fair projects you will be able to read all about it.

So, on to our little science e project:

This is what you will need:

A few stirring paddles that you will get from a paint store
Some broad double sided tape
A felt marker
A camera for your photos
A note book and a pencil for your notes

This is what you have to do:

Stick the double sided tape onto the paddles (as many as you wish to use)
Now you stick the paddles into the ground in various places close to your home, ask an adult to go with you for safety’s sake, mark each one clearly and write it down in your note book.
Make sure the paddles face in different directions such as north, south, east, west, northwest and so on.
Now check on these paddles at regular intervals, say about twice a week.
Record what you see on the paddles and take photos.
Make sure you make a not of the location of each paddle

This project will show you how much wind erosion is in your vicinity by the amount of dust and dirt that are collected on the puddles. Write down exactly what happens and why you think there is a difference in the different paddles. What lies in the vicinity from where the wind came? Did that have any influence on the amount of dirt on the paddles? Does the wind blow mainly from one direction where you stay? Do you think that can have an influence on your project?

These are some of the questions you will be able to answer in this science project. To see exactly how you have to do it, go and have a look at Super Science Fair Projects.

Osmosis Science Project

Magriet — Fri, 26 Feb 2010 13:48:17 +0000

There are many variations on the well know “flower changing color” science project. It is always a fun and very visual science fair project for kids to do. If you do not have a lot of time, this is a good one to try as it can be done in a relatively short time.

If you do not have any time left over at all, do go and have a look at 24 Hour Science Projects as you will get science fair projects there that you can do in 24 hours or less! Complete projects with all the details you need.

For a fun project that also uses osmosis as a part of the project have a look at Elementary Science Fair Projects: Sweet or Salty Flowers?

Now for our fun osmosis science fair project; the Green Highways project:

The purpose of the project is to show how plants carry nutrients and water to all the parts of the plant. Here is a fun way to show how it happens.

Here’s what you will need:

1 Fresh stalks of celery
2 Glasses of water
Red food coloring
A knife (let an adult help you with this)

This is what you have to do:

Put the two glasses of water next to each other
The one glass is going to be your control (do you know what a control is?)
Color the water in the one glass dark red by dropping four to five drops of red food coloring into it
Now you have to cut off the dried bottom part of the stalk of celery
Cut the stalk in half from the bottom to the leaves.
place one half in the clear water and the other in the colored water and make sure they are standing securely and will not fall over.
Check on your project every hour to see what is happening
Make meticulous notes and take photos if it is possible, for your display

What happens?

What do you see happening?
Why is it happening?
What is the process called?
What does this prove?

Remember all science fair projects, as this osmosis science fair project, must start with a hypothesis, then you do the project using proper scientific method and then you reach a conclusion that either proves your hypothesis correct or wrong. Whether your osmosis science project hypothesis was wrong or correct is not important. What is important is that you followed proper scientific method and reached a proper conclusion.

Examples Of Science Fair Projects – Alternative Bread Mold Project

Magriet — Fri, 12 Feb 2010 15:21:39 +0000

For really good help with science fair projects you can have at 24 Hour Science Projects e-Book.

In this example science fair project you are going to find out what are the ideal conditions for the growth of molds on bread and what can be done to prevent the growth of mold. Molds are fungi and with bacteria they grow on organic materials and causes (or helps with) decay. So, this is one of our alternative Simple Science Fair Projects a Bread Mold Science Fair Projects

This is one of our examples of science fair projects where adult supervision is needed as heat is going to be used and because of the potential danger of the mold growing.

What you need for your science project:

4 Slices of bread

3 Sealable plastic bags, big enough for your slices of bread to fit in it

A Pair of rubber gloves

Tags to mark your bags with

A knife

Antiseptic cream

A piece of kitchen towel

A small plate

A note book

Camera

How to do your project:

1. We are going to use three different conditions: completely dry bread, normal bread as it is and bread spread with antiseptic cream. Our problem is to find out the conditions that speeds up decay, in this case the mold growing on the bread.

2. Formulate your hypothesis on what you think will happen

3. For your control place a piece of kitchen towel on a plate, place a slice of bread on the plate and place it in a cool dry place. (Why on a piece of paper towel?)

4. Take one of your slices of bread and completely dry it out in the oven at a very low heat.

5. Let it cool down completely. (Later on you should be able to give reason why it has to cool down completely)

6. Place the cold piece of “toast” in one of the plastic bags and mark it with a tag.

7. Place another slice of bread in one of the bags just as it is and mark the bag.

8. Spread your last slice of bread with antiseptic cream on both sides and place it in the last plastic bag and mark it.

9. Now you have to leave them in a warm (not hot) place.

10. Each day you have to make your observations, write it down and take a photo of your experiment. Do not forget your control.

11. Keep this up for a week.

12. You are now ready to write your conclusion, remember to give the reasons for what has happened to your slices of bread. Include your control in your conclusion. Your control shows what happens when you do not do anything, this id how you can draw the correct conclusion about what has happened to your other slices of bread.

* Do you know why the toast had to cool down completely before you placed it in the plastic bag?

* Is there only one reason for what happened to the toast or are there more than one?

* Why did you have to place your control on a piece of kitchen towel?

To get all the answer for doing a top science fair projects I recommend that you Download 24 Hour Science Projects e-Book.

Examples Of Science Fair Projects

Magriet — Fri, 12 Feb 2010 15:16:17 +0000

Getting good examples of science fair projects are not always that easy. It feels as if it has all been done before. Or maybe you have left it too late and now you are desperately searching for a good idea. This is what this post is about.

I’m taking well know examples of science fair projects and giving them a new twist, this should freshen them up a bit! Use them as the start of building your own unique project. If you want to do a really exceptional science fair project, I can strongly recommend 24 Hour Science Projects e-Book! In this e-book you will get all the info you need to do a winning science fair project.

Examples Of Science Fair Projects – Preservation And Decay Examples

These preservation and decay examples of science fair projects are variations of some of the most well know examples of science fair projects with a twist in them. Look at what causes certain things decay faster than others and do the bread mold one a little different.

Caution: Because a knife is used in this experiment adult supervision is needed. It is also necessary that an adult make sure the kids do not handle the rotting fruit and vegetables without their gloves on. Although these examples of science fair projects are easy and all kids can do it, it is best done under adult supervision.

What you need for your “what will decay” project

* 3 Each of a variety of fruit and vegetables such as apples, pears, carrots, potatoes, oranges etc. The more fruit you have the better the picture you’ll get.

* A pair of rubber gloves

* A knife or peeler

* A small piece of plastic

* A stone

* A piece of wood

* A large plastic garden tray with holes in the bottom (big enough to hold all the fruit and vegetables you have)

* An old newspaper

* A bag of compost

* A garden spade

* Pen

* Note book

* Camera

How to do your project:

1. Formulate your problem and formulate your hypothesis before you start with your science experiment.

2. Make very detailed notes of every step of your science project and give the reason for everything you do.

3. For your control, keep one of each kind of your fruit in a dry cool place for the length of your project. Every time you dig up your project make sure to also make notes of what is happening with your control. Take photos to make it easier.

4. Line your garden tray with newspaper and cover it with a layer of compost.

5. Place the piece of plastic, stone and piece of wood in the tray.

6. Peal one each of all your fruit and vegetables, leaving one of each kind unpeeled.

7. Place one peeled and one unpeeled fruit and vegetable in the tray with the other objects.

8. Completely cover them with the compost.

9. Now get an adult to help you dog a shallow hole in the garden in a shady area.

10. Place your tray in the hole and cover it with soil until only the top edge of the tray is visible (so you can dig it up easily later)

11. Buried like this the fruit and vegetables will remain moist.

12. Leave your project for a week.

13. Dig the tray up.

14. Inspect all the fruit and vegetables as well as the plastic, stone and wood.

15. Make detailed notes of what you see.

16. Take photos of your tray with everything on it.

17. Bury your tray again in the same manner.

18. Leave your project for another week and repeat your observations.

19. Keep this up until some of your fruit and vegetables as decayed completely.

20. In dry climates it may be necessary to dampen the soil a little if it gets completely dry. Do not soak it though, simply dampen it a little.

21. Make sure that you make very clear notes about the stages of everything in your tray every time you take it out.

22. You must also make sure that you take enough high quality photos for your display.

23. Now you will be able to write your conclusion and to discuss your findings. Where your hypothesis correct? Remember, whether you were right or wrong is not important, what is important is that you followed the correct scientific method and how you arrived at your conclusion.

* Why did the fruit and vegetables with their skins on decay at a different rate than the peeled ones?

* Why did the plastic and the stone stay the same?

* What happened to your control fruit and vegetables and why?

To do a really good science fair project there are many things to take in to account. You must also make very sure that you follow the correct scientific method.

Getting a good e-book to help you may be a good idea. A good e-book will guide you through all the steps and make very sure that you do not leave something out. Download 24 Hour Science Projects eBook! With this amazing e-book you will get all the help you need.

Science Fair Food Projects – How To Stop Food From Rotting

Magriet — Wed, 22 Apr 2009 15:52:50 +0000

Science Fair Food Projects – How To Stop Food From Rotting

24 Hour Science Projects

This is one example of our easy science fair food projects the kids will enjoy. You will need about two weeks to complete it so, if you have waited until the last minute it may be a good idea to have a look at 24 Hour Science Projects where you will find many you can do in 24 hours or less.

This experiment is going to show us why some substances can be used as preservatives. What is a preservative? In this experiment we are going to look at natural preservatives and not chemicals developed by scientists.

Science fair food projects always have a very practical lesson for the kids to learn and this one is no exception. They will see why some ordinary household food ingredients have been used for centuries to preserve food, especially before refrigerators and freezers where available!

After the project has been completed, let an adult dispose of all the food as it may be rotting. It is also best to let an adult do all the cutting involved.

What you will need for your experiment:

An apple sliced into six equal pieces
6 Small jars
Enough salt to fill a jar
Enough sugar to fill a jar
Enough antibacterial soap to fill a jar
Enough vinegar to fill a jar
Enough water to fill a jar
A felt tipped pen
Some paper plates
Labels to label your jars with
A knife
Disposable utensils to work with the rotting apple pieces (so your hands do not come into contact with them.)

How to do your experiment:

Label the jars as follows: sugar, salt, vinegar, antibacterial soap, water and control.
Do you know what the “control” is for? This goes towards the proper scientific method.
Now you place a piece of apple in each jar.
Remember to take photos of each step for your display
Now you have to completely cover the apple pieces with each substance.
In the jar marked “sugar,” you cover the piece of apple completely with sugar and in the jar marked “salt” you cover the piece of apple completely with salt etc.
In the jar marked “control” you do not cover the piece of apple with anything.
Do you know why you do not cover the piece in the “control” bottle with anything?
Now you have to place the jars in a cool place
After one week your take the jars and examine their contents.
Make detailed notes of all the changes and do not forget to take photos
When you want to look at the pieces in the sugar and salt where you cannot see through the substances, throw them out on a paper plate and use the disposable utensils to dig them out and look at them
Which apple pieces rotted?
Which of the pieces have the appearance that they have been preserved?
Do the preserved pieces appear dried out?
Can you observe any color changes in the pieces of apple?
Can you notice any difference in the texture of the apple pieces?
These are all the things you have think of and make meticulous notes of.
Remember your photos!
Now it is only a case of putting your display together and you will have done one of our fun science fair food projects.
