Winter Weather Day 4: What Makes the Wind Blow?
Demonstrate the answer by creating a mini hot-air balloon in the classroom!
- Grades: PreK–K, 1–2
- Unit Plan:
Student learn about the properties of wind. They make a miniature hot-air balloon and compose diamond-shaped poems about the wind.
- Discover the properties of wind
- Empty soda bottle
- Thermos full of hot water
Set Up and Prepare
- You may wish to conduct this experiment yourself before class time. That way you will be familiar with the process when you demonstrate the experiment for your class.
Step 1: Review with children what they learned about the wind yesterday.
Step 2: Explain to them that today they will learn what makes the wind blow.
Step 3: Demonstrate what makes the wind blow by following these steps:
- Place the balloon over the mouth of the soda bottle.
- Pour a few inches of hot water from the thermos into the pan.
- Set the soda bottle in the hot water. After a few moments, the balloon will stand straight up as the air inside the bottle warms and expands into the balloon.
Step 4: Explain that as the sun warms air around the earth, the air rises. Colder air then moves in to fill the vacant spot.
Step 5: Ask children what the moving air is called? Wind!
Step 6: Ask children what a windy winter day feels like. Encourage them to use degrees of temperature to describe a cold and windy winter day.
Have children write a diamond-shaped poem about the wind. Explain to children that the first line of the poem is the one-word subject of the poem. (For example, wind.) The second line consists of two adjectives describing the subject (cool, gusty). The third line contains three verbs telling what the subject does (blows, sweeps, howls). The fourth line expresses, in two words, the writer's feelings about the subject (wonderful wind). The last line repeats the first.
