Science has a magical appeal for children. While they are entertained by science demonstrations, nothing is as captivating as something they can do themselves.
The best TEACHING TIP I have for club directors is to support and encourage children’s inborn gift of curiosity
One way is to explore the fun of science TOGETHER.
Instead of giving all the answers, guide activities so that kids discover answers for themselves.
For an additional activity and information about why the ball is floating above the hair dryer, see BERNOULLI’S PRINCIPLE
DISCOVERING TOGETHER
The hair dryer is on its coolest setting. Test different balls to see which will float.
The best way to get kids involved is to ask cause-effect questions, such as the following.
Each of the following questions has an independent variable (CAUSE) that you change in order to determine what kind, if any, change occurs in a dependent variable (EFFECT).
1. How does the speed of the air from the hairdryer affect the height of the floating ball?
2. How does the speed of the air from the hairdryer affect the weight OF THE BALL that will float?
3. How does the weight of the ball affect its height above the hairdryer?
