Cool Science Fair Projects - The Power Of Growing Flowers

This is one of our cool science fair projects that show the strength of growing plants.

What you need for this science fair project:

• A sheet of clear plastic
• A healthy potted plant
• A box of paper clips
• 2 Small boxes just a bit higher than the plant

How to do this cool science fair project:

1. Take your healthy potted plant and place it on a windowsill that gets enough sun.
2. Now you place the two boxes on each side of the plant taking care not to shade the plant.
3. Lay the plastic across the boxes and let it hang down the two sides of the boxes.
4. Make two chains that are identical with the paper clips
5. Lay these chains over the clear plastic so that it hangs down the sides of the boxes.
6. Arrange them evenly and mark their positions on the boxes.
7. Now you care for the plant as normal.
8. Check and mark the positions of the chains from time to time

What has happened?

• Make note of what happens?
• Measure the markings as they move up the boxes.
• Why do the chains move up?

Explanation:

This experiment shows us how strong plants are. As the plant grows it pushes the plastic and thus the chains up. Now you can see how plants can be so incredibly strong and grow through blocks of cement and why weeds push through the sidewalk cracks to reach the light (Plants need light to stay alive and grow)

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.
