This is one of our examples of science fair projects that is very easy and are suitable for elementary school kids. We are going to use sand to represent the land and water the ocean. It is going to show us why temperatures close to the sea is more moderate. Winters close to the sea tends to be milder than inland. Humidity can also influence how hot it feels. In more humid conditions it feels hotter, even though the temperature is the same.

Now on to our measuring temperature experiment

What you need for this experiment:

• Sand
• A jug of water
• Two bowls
• A thermometer
• A note book
• A pen

How to do your science project:

1. Pour water into one of the bowls and sand into the other bowl. It is not necessary to measure the quantities exactly it must just be more or less the same quantity.
2. Now you have to place the two bowls in a cool place together.
3. Leave them there for a few hours.
4. Measure the temperature of both, make sure it is the same otherwise leave it for a while longer until they are the same temperature.
5. Make a note of the temperature.
6. Now you have to place both bowls in a sunny and hot place for about two hours until they are very hot.
7. Measure and record the temperatures of both bowls and make a note of it.
8. Put both bowls in a cool place indoors.
9. Now you have to measure the temperatures of the water and the sand every 15 minutes and write it down in your not book.
10. You should notice that the sand cools down much faster than the water.
11. You can also dip your hands in both and feel the difference. You can make a note of it as well but, of course your real evidence is not what you feel but the temperatures you recorded.
12. Why is it that there is a difference?
13. Where does the heat come from?

This is a very easy science fair projects and is also one of our examples of science fair projects that is very suitable for homeschooling. If you need more examples of science fair projects, you can visit Easy Science Fair Projects.

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.
