Protection from Wind Force

Materials Required:

1. An adult
2. A place with many trees
3. An open space, away from trees and buildings
4. Plastic-foam drinking cup

Trees seem friendly. They are colourful and appealing. People hang swings from them and birds build nests in them.

In destinations facing extreme cold winters, strong winds can make it harder to heat a house. Do trees stop the wind? If trees are planted around a house, can they help make it easier to heat the house?

On a windy day, go with an adult to an open place away from buildings and trees. Put a stone or a small rock on the ground.

Take a plastic foam drinking cup and with your fingers, break off four small pieces. Hold one piece in your hand and raise it in front of you, to as much height as possible, above the rock on the ground. Be sure that you are standing, so that your body is not blocking the wind. Let go off the piece. Mark the spot, where it first hits the ground. Use a measuring stick or steel ruler to see how far the wind blew the plastic-foam away from the rock. Write down the distance. If it is a windy day, the piece of the cup might blow too far. If that happens, use something heavier to drop, like a small piece of cloth. The cloth can be a little wet to make it heavier, if needed.

Repeat this test again three more times. Each time use a different piece of plastic foam or cloth. Measure and write down the distances from the rock to the piece. Add the four distances and divide them by four to get the average distance, the wind blew the pieces. Pick up all the plastic foam or cloth pieces and the rock when you leave. Do not litter.

Next, find a group of trees. The trees must have branches that go all the way to the ground, or there must be any bushes or shrubs-surrounding the trees. Put the rock close on the ground, close to the trees. Again standing by the rock, raise your hand to the maximum height you can reach, in front of the rock and let go off the plastic foam. Measure, how far the wind blows away the foam from the rock. Write down the distance.

Repeat this exercise, three more times. Use a different piece of foam cup each time. Measure and write down the distance from the rock to the piece of cup.

Add the four distances together. Divide the answer by four to get the average distance, the wind blew the pieces.

The stronger the wind, the farther the foam pieces will be carried. Which average distance was larger, the pieces dropped in the open space or near the trees? What does this mean?

On which side of your house, should you plant trees and shrubs to help protect your home from the winter winds (North, South, East, West)?

On which side of your house should you plant trees and shrubs to help protect them from the summer sun (North, South, East, West)?

Why do you think farmers might want to use trees to stop the wind?
