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

Science Fair Projects Kids Will Enjoy Part Seven – Static Electricity

24 Hour Science Projects

Here is part seven of our Science Fair projects Kids Will Enjoy about static Electricity. In this experiment we are going to see how to objects that are negatively laden are attracted to objects that are positively laden. Once the objects are no longer negatively laden, they are not drawn by a positively laden object any more.

Remember for a full science project you will have to combine this whole series, so, I hope you have time to wait for them all! If not, there is a very good solution for you, go to 24 Hour Science Projects; there you will find complete science fair projects you can do in 24 hours or less! So, if you are in a hurry, go to 24 Hour Science Projects now!

Here are our science fair projects kids will enjoy:

Remember, for all science fair projects you have to make notes of everything you do, why you do it, what you are trying to prove or demonstrate and your conclusion. It is always a good idea to take photos for your exhibition.

The case of the dancing paper dolls:

What you need for your experiment:

Two books
A glass disk
A metal plate
Two books
Tissue paper dolls about 3cm tall (cut any way you prefer as long as they not too big)
A woolen cloth

How to do your experiment:

Cut out your paper dolls (about 3-4)
Place two books a little way apart with the metal plate between them
Place the glass disk over them to be over the metal plate
Place the paper dolls in the metal plate
What happens when you place the paper dolls on the metal plate under the glass disk?
Now rub the glass disk with the woolen cloth for a few minutes
What happens?
Why does it happen?

By rubbing the glass disk with the woolen cloth it is loaded with electron to make it negative
Now the disk draws the positively laden paper dolls and they are also loaded
Now they drop down and the metal plate draws the electrons from them, once again making them positive
Now the glass draws them again and so the dance continues

I think this can be quite a good display for your friends to admire!

This is the seventh of our short series of science fair projects kids will enjoy. Look out for the others as doing all these experiments as one will probably be the best way of doing a thorough science fair project.

Science Fair Projects Kids Will Enjoy Part Five – Static Electricity

24 Hour Science Projects

Here is part five of our Science Fair projects Kids Will Enjoy about static Electricity. In this experiment we are going to see how to objects that are negatively laden “push” each other away. Opposite to a negative and positive drawing each other.

Here are our science fair projects kids will enjoy:

The case of the hostile balloons!

What you will need:

2 Balloons
2 pieces of string
A wooly sweater

How to do this experiment:

Blow up both balloons as much as possible without bursting them
Tie them with the strings
Rub both on your sweater for a few minutes
What happens?
Why do you think it happens?
What happens to the balloon closest to your sweater?

After you have rubbed the balloons on your sweater, they are both negatively laden with electrons they withdrew from your sweater. Because the sweater has given off the electrons it is now positively laden, this is why the balloon closest to your sweater sticks to your sweater while the two balloons drift far apart. So, what does that tell you about two objects that are negative or positively laden?

This is the fifth of our short series of science fair projects kids will enjoy. Look out for our next post as doing all these experiments as one will probably be the best way of doing a thorough science fair project.

Easy Elementary Science Projects: Eggs and Pollution

Magriet — Sat, 21 Feb 2009 15:07:55 +0000

This is one of our easy elementary science projects to show the effect of oil pollution on sea life. (On all aquatic life.) It is horrifying to see what oil is capable of doing and this experiment will show the kids that all the worrying about oil spills in the sea is not exaggerated and that it in fact has devastating results. This easy elementary science project is also very suitable for homeschoolers.

What you need for this experiment:

4 Hard boiled eggs
4 Sealable plastic bags
Water
Food coloring
Motor oil or other wise olive oil as a substitute
Felt marker
A watch or a timer
Some masking tape

What to do:

1. Take your 4 bags and mark them 1, 2, 3 and 4.
2. Now you fill each bag with ½ Cup of water and ½ Cup of your oil.
3. Drop a few drops of food coloring into each bag, mix it well with the oil.
4. Take your hard boiled eggs and place them in the bag.
5. Now you remove the eggs from the bag as follows
#1 after fifteen minutes
#2 after half an hour
#3 after an hour
#4 after two hours
6. Each time you have removed the egg from the bag, carefully peel the shell off the egg.
7. Write Down your observations.
8. You will notice that the longer the egg stayed in the oil, the more oil got inside the shell of the egg. (The food coloring makes it easy for you to see that.)
9. Remember to make accurate notes of everything you do and it is best if you also take photos of the results for your display.

Doing Elementary science fair projects need not be a problem. There are tremendous e-books available that gives you all the ideas and information you need. I find 24 Hours Science Projects very good as it gives you complete experiments from hypothesis to conclusion that can be done in 24 hours or less. This is important because it prevents your home from being taken over by the project for months on end.

Examples Of Science Projects – Fun Experiments On Liquid Density

Examples Of Science Projects – Fun Experiments On Liquid Density

We have a number of short Examples Of Science Fair Projects. In this short easy elementary science projects we are going to see some of the interesting things that happen because of the density of liquids. The density of and object has to do with how tightly packed the object is. Two objects can weigh the same but one is smaller than the other, the smaller one is packed more tightly and is therefore denser than the other object. These experiments are meant to make learning fun and are also very suitable for homeschoolers.

The floating egg experiment

What you will need for this easy elementary science project:

A container
Water
An egg
Salt
A spoon

This is what you have to do for this easy experiment:

Fill the container with enough water to cover the egg completely.
Carefully place the egg in the water.
What happens to the egg?
Make a note of what happens.
Start adding salt to the water and stirring it very carefully so as not to break the egg.
Keep on adding salt until your egg starts to float.
You will need quite a lot of salt, about 4 tablespoons full of salt per 1 ½ cup water to make the egg float.
Now you add water to your solution again until the egg start sinking again.
Keeping density in mind, try and explain what just happened.

If you worked carefully and did the experiment the right way your egg started rising because it became less dense than the water when you added the salt. When you added extra water, the water once again became less dense than the egg and the egg started sinking again.

This is one example of our easy elementary science projects, one of many examples we have of science fair projects.

Easy Elementary Science Projects – Air In Soil

Magriet — Wed, 10 Dec 2008 14:59:53 +0000

Easy Elementary Science Projects – Air In Soil

This is one of our easy elementary science fair projects where it is best to a camera to record your findings as it is all visual. There will be nothing for you to measure or evaluate only what you see visually.

The idea of this easy elementary science project is to see if there are different amounts of air in different kinds of soil.

What you need for this easy elementary science project:

A camera
3 Small clear jars
Water
Samples of three different kinds of soil, e.g. clay, good with lots of organic matter in it and very sandy soil

How to do this easy elementary science projects:

Half fill the jars with your soil samples
Fill the rest of the jars with water until almost to the top
Make your observations as air bubbles rises to the top of the jars.
Take photos every few seconds to record your findings
Why are we looking at the bubbles rising in the water?
What does it prove?
In which kind of soil did the most bubbles rise to the top?
What does this prove?

Well, the more bubbles rising through the water, the more air was trapped in the soil sample. Tightly packed soil has less air trapped in it than soil with a lot of humus or other organic matter. Almost all kinds of plants tend to grow better in this kind of soil.

I think this experiment is one of our easy elementary science fair projects that are for the budding “gardeners” amongst our young! Enjoy!

Easy Elementary Science Projects: Cleaning A Copper Coin With Lemon Juice

Magriet — Wed, 18 Jun 2008 18:41:06 +0000

Easy Elementary Science Projects: Cleaning A Copper Coin With Lemon Juice

This experiment is another of our easy elementary science projects that uses lemons or lemon juice. We are going to use lemon juice to react with the copper oxide and to remove it in that way. When a copper coin is exposed to the air it reacts with oxygen in the air to form copper oxide that gives the coin a dull appearance.

What you need for this easy elementary science project:

4 Tablespoons of lemon juice
2 dull copper coins
A glass
Water
A soft cloth
A camera

What you have to do for this project:

Take a photo of your coins before you start, making sure they are both more or less the same in color (dull)
Pour the lemon juice into a glass
Drop the coin into the lemon juice
Leave the coin in the lemon juice for about 5 minutes
Remove the coin from the lemon juice, rinse it clean and dry it with a soft cloth
What has happened?
Take a photo of both coins next to each other to show the difference.
Explain what has happened.

Doing easy elementary science projects are a lot of fun. If you want to make very sure you are following the proper scientific method it may be a good idea to get a good science fair project e-book. I have found Science Fair Projects Made Easy to be a very good one; you may want to have a look at it.

Examples Of Science Fair Projects – Air Pressure And Air Weight

Examples Of Science Fair Projects – Air Pressure And Air Weight

Get more Science Fair Projects at Easy Science Fair Projects

This science project is one of our examples of science fair projects where you actually proof two related characteristics of air. You will prove that air has weight and that, because of the weight, air pressure is strong enough to bend a can. We are going to use the principle that as air heats up; it has a greater volume and if it is in a container some of the air will escape from the container. Then by screwing a top on the container we are going to prevent the air from going back in when the container cools down.

CAUTION: This example science fair project must be done with adult supervision as heat is used.

What you will need for this experiment:

Large container
A can with a screw top (you get cans of olive oil that will be the ideal can)
Water
Stove
Oven mitts
Ice
Dish cloth
A scale
Note book
Pen
Camera

How to do this science experiment:

For your display, it is a good idea to take a photo of the can in its original state.
Fill the large container with water and ice and put it to one side until you need it.
With a finely calibrated scale, weigh the can with the screw top on.
Make a note of this weight.
Remove the screw top.
Put the can on the burner on the stove.
Heat the can until it is very hot.
Using the oven mitts, remove the can from the stove and, working quickly, screw the top on the can and place it in the cold water.
Observe what happens, write it down and take a photo.
When the can has cooled down, wipe it dry and weigh it.
Make a note of the weight and take a photo.
What has happened?
Why do you think it happened, remember we said in the beginning that we are going to prove two things?

What happens is that the air pressure bends the can. Why can we say that? What did we do to remove air from the can so that the air pressure on the outside is more than in the inside?

The other thing that happens is that the can now weighs less. Why is that? Think of what we have done with the air in the can.

This is just one of our many examples of science fair projects. For more fun and easy examples of science fair projects visit our site Easy Science Fair Projects.
