"Who flows faster" Water and Air PPT

Part One: Mobile Competition

Do three common liquids, water, cooking oil and dish soap, flow equally fast? Who will bleed faster? Let’s talk about our guesses.

How can we prove who flows faster? Let's design a flowing match.

What can be done to ensure that mobile competitions are fair?

same amount of liquid

same height

Start at the same time

Conduct experiments based on the design to test our guesses.

Kind tips:

1. Create a good division of labor within the group.

2. Work together and repeat three times. If the experimental results are different, think about what caused the different results.

3. Keep experimental records and discuss what is related to the speed of liquid flow.
