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.

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. Once again, if you are unsure, go to 24 Hour Science Projects.

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:

1. Label the jars as follows: sugar, salt, vinegar, antibacterial soap, water and control.
2. Do you know what the “control” is for? This goes towards the proper scientific method.
3. Now you place a piece of apple in each jar.
4. Remember to take photos of each step for your display
5. Now you have to completely cover the apple pieces with each substance.
6. 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.
7. In the jar marked “control” you do not cover the piece of apple with anything.
8. Do you know why you do not cover the piece in the “control” bottle with anything?
9. Now you have to place the jars in a cool place
10. After one week your take the jars and examine their contents.
11. Make detailed notes of all the changes and do not forget to take photos
12. 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
13. Which apple pieces rotted?
14. Which of the pieces have the appearance that they have been preserved?
15. Do the preserved pieces appear dried out?
16. Can you observe any color changes in the pieces of apple?
17. Can you notice any difference in the texture of the apple pieces?
18. These are all the things you have think of and make meticulous notes of.
19. Remember your photos!
20. Now it is only a case of putting your display together and you will have done one of our fun science fair food projects.

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:

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.

If you want to make sure you do a really winning science fair project; go to 24 Hour Science Projects now! Access is instant; your project can be ready tomorrow.

Science Fair Projects Kids Will Enjoy Part Six – Static Electricity

24 Hour Science Projects

Here is part six of our Science Fair projects Kids Will Enjoy about static Electricity. In this experiment we are going to see how to a spoon, laden with static electricity, will draw puffed wheat or rice to it. Opposite to a negative and a negative “pushing” each other away as in our previous example.

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!

The case of the plastic spoon and the puffed wheat or rice:

What you will need for this experiment:

• A bowl of puffed wheat or rice
• A plastic teaspoon
• A wooly sweater

How to do your experiment:

1. Without doing anything to the spoon, keep it just above the bowl of puffed wheat or rice.
2. What happens?
3. Rub the spoon on your sweater for a few minutes to load it with the extra electrons until it is negative.
4. Now hold the spoon just above the bowl of puffed wheat or rice.
5. What happens?
6. Keep the spoon there.
7. Why does it happen?
8. What happens after a short while?
9. Why does it happen?

After you have done all the previous science projects, you should be able to explain what happened here. Remember you should be able to give a scientific explanation for every step and why you are doing it.

Have a look at all our other science fair projects kids will enjoy to see how the whole process follows one on the other. It is important with these science fair projects kids will enjoy to do them all to make a complete science fair project. If you are in a hurry, go to: 24 Hour Science Projects now!
