In our previous good science fair project we had a look at chlorophyll and how plants use this chlorophyll, sunlight, water and carbon dioxide to produce glucose (a form of sugar.) What else, that is very important, is produced through photosynthesis? (In the process carbon dioxide is taken from the air, what is released back into the air?) Now we are going to do a good science fair project to demonstrate how plants actually reach for sunlight. We know by now that they cannot survive without light, which we proved in our previous science fair project. Now we are going to do a really fun science fair project. If you want to do a really good science fair project, it might be a good idea to combine these two science fair projects as it gives you a very clear and visual picture of plants growing and needing sunlight.

Today’s science fair project is a good science fair project for someone that is a little handy. We are going to make a maze in a shoe box to demonstrate how the plant searches and reaches for light.

What you will need for your good science fair project:

* First you need a shoe box
* You will need a pair of scissors
* Stiff card
* Some sticky tape
* Black paint
* A paint brush
* A pair of gardening gloves to protect your hands
* A runner bean
* A plant pot
* Some good compost
* Water

Now for the fun part: making your maze in your shoe box!

1. To start cut a hole in the one end of the shoe box.
2. Making a maze in your shoe box is very easy, start by cutting eight flaps out of the stiff cards. The flaps must fit securely into your shoe box in the width.
3. Now paint your shoe box and the eight flaps all over with black paint. Do you know why we are doing that? Think about the light reflecting…yes, the black paint is to stop the light entering through the hole from reflecting inside the shoe box!
4. Now you can make a maze by sticking the eight flaps of card inside the shoe box with sticky tape. Cut slots into your flaps at a different place in each flap to form a maze (if you are not sure how to do this, ask for the help of an adult who knows what a maze looks like.)
5. Plant a runner bean in a small plant pot with compost.
6. Water the soil each day to keep it moist but, do not make it too wet. Keep it in a warm place until the bean has a shoot. Remember to keep the soil moist, depending on the temperature; it may not be necessary to water the bean everyday.
7. When your plant has a shoot place it at the bottom of your maze.
8. Close the lid and place the maze in a sunny spot.
9. Remove the lid once a day to see if your plant needs water.
10. Now you can observe what is happening.
11. If you did it right, the plant will grow and find its way through your maze to steadily move towards the light.
12. Eventually your plant will poke through the hole at the top of your shoe box.
13. For display purposes it is a good idea to take a photo of your plant growing zig-zag through your maze and out the hole at the top.

This is one of our good science fair projects for those that like to make things and our prospective gardeners!

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:

1. Take a photo of your coins before you start, making sure they are both more or less the same in color (dull)
2. Pour the lemon juice into a glass
3. Drop the coin into the lemon juice
4. Leave the coin in the lemon juice for about 5 minutes
5. Remove the coin from the lemon juice, rinse it clean and dry it with a soft cloth
6. What has happened?
7. Take a photo of both coins next to each other to show the difference.
8. 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

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:

1. For your display, it is a good idea to take a photo of the can in its original state.
2. Fill the large container with water and ice and put it to one side until you need it.
3. With a finely calibrated scale, weigh the can with the screw top on.
4. Make a note of this weight.
5. Remove the screw top.
6. Put the can on the burner on the stove.
7. Heat the can until it is very hot.
8. 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.
9. Observe what happens, write it down and take a photo.
10. When the can has cooled down, wipe it dry and weigh it.
11. Make a note of the weight and take a photo.
12. What has happened?
13. 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.
