Easy Science Fair Projects

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:

1. Put the two glasses of water next to each other
2. The one glass is going to be your control (do you know what a control is?)
3. Color the water in the one glass dark red by dropping four to five drops of red food coloring into it
4. Now you have to cut off the dried bottom part of  the stalk of celery
5. Cut the stalk in half from the bottom to the leaves.
6. 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.
7. Check on your project every hour to see what is happening
8. 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.

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

• Pen

• 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?

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.
