Easy Science Fair Projects

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:

1. 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.”
2. 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.
3. Now you have to sprinkle a little water in the jar and make sure you moisten all the food, do not soak it though.
4. Do you know why you are doing this?
5. Close the jar with the lid
6. Place the jar on a counter top where it will not be disturbed and also out of direct sunlight.
7. Now you do exactly the same with the second jar except you do not sprinkle any water on it.
8. 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.
9. It is important that you now observe the changes that happen in the jar everyday.
10. Record everything you see and take photos every day.
11. 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!

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:

1. Cut out your paper dolls (about 3-4)
2. Place two books a little way apart with the metal plate between them
3. Place the glass disk over them to be over the metal plate
4. Place the paper dolls in the metal plate
5. What happens when you place the paper dolls on the metal plate under the glass disk?
6. Now rub the glass disk with the woolen cloth for a few minutes
7. What happens?
8. 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.

The case of the hostile balloons!

What you will need:

• 2 Balloons
• 2 pieces of string
• A wooly sweater

How to do this experiment:

1. Blow up both balloons as much as possible without bursting them
2. Tie them with the strings
3. Rub both on your sweater for a few minutes
4. What happens?
5. Why do you think it happens?
6. 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.
