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

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?

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.
