Investigate-to examine, study, or inquire into systematically.
Explain-to make known in detail.
Air-a mixture of nitrogen, oxygen, and minute amounts of other gases that surrounds the earth and forms its atmosphere.
Wind-air in natural motion.
Students need to understand that air is all around us. Just because you can not see it, doesn’t mean that it is not there. Air is always around us. Students also need to realize that the movement of air is known as wind. Wind is air in natural motion.
Students will investigate and explain that air is a substance that surrounds us, takes up space, and whose movements we feel as wind.
Activate Prior Knowledge
Ask students questions
-Where is air?
-Is air touching you right now?
-When air moves outside, what do we call it?
-“Today we will be investigating and discussing further that air is a substance that surrounds us, takes up space,and whose movements we feel as wind.
Write on Chalkboard
-Air surrounds us.
-Air takes up space.
-We feel air’s movement as wind.
Instruct students to take out a piece of paper.
Ask: “How can you use air to get your paper from one side of your desk to the other?”
Instruct students to test their ideas
-Did the air move?
-How do you know?
-Is air all around us?
Air Takes Up Space
Ask: “Do you know how I can make this balloon bigger?”
Say: “There are many ways I can make this balloon bigger, but I am going to try using air.
Blow air into the balloon.
Air Takes Up Space…continued
Hold balloon so air doesn’t escape and ask:
-Is the balloon getting bigger?
-What is taking up space inside the balloon?
-How do you know that air is going in the balloon?
Finish filling balloon and tie it off.
Compare a deflated balloon and an inflated balloon.
How did air help you move the paper?
What else has the wind helped you move?
-How did you know it was the wind?
Why are tires tall and round instead of short and flat?
-How are tires like balloons?
More questions can be developed after observing the class.
