Objective: Children will explore wind and what causes wind.
The wind is air in motion. As the Sun warms the Earth’s surface, it also warms the atmosphere. Warmer air in the atmosphere is lighter than colder air. As cold air moves in, it pushes under the warm air, causing the warmer air to rise. This movement of the air is what makes the wind blow. The wind can be described two ways: by speed and the direction it is blowing. Short bursts of wind are known as wind gusts.
The wind is helpful to the Earth. The wind helps spread seeds, and the wind can cool us on hot summer days. Wind moves sailboats and is necessary for a variety of outdoor activities such as windsurfing, kite boarding, and parasailing. The energy from the wind can be harnessed to create electricity for people to use.
Perform this experiment on a day that is windy enough to blow leaves and the tops of trees, but not so windy that it causes tree branches to break off.
These lessons are aligned with the Common Core State Standards ("CCSS"). The CCSS provide a consistent, clear understanding of the concepts and skills children are expected to learn and guide teachers to provide their students with opportunities to gain these important skills and foundational knowledge.
