Diving Paper

Diving Paper

• Question: Does air occupy space?

Diving Paper

• Materials:– Sheet of paper– A drinking glass– A clear container filled with water

Diving Paper

• Procedure1. Crumple up the piece of paper and push it into

the bottom of the glass2. Turn the glass over and push it straight down into

the container of water3. Observe and record results

Diving Paper

• Diagram

Diving Paper

• Results:– Air stays in the glass– Some water gets in the glass– The paper does not get wet

Diving Paper

• Inference: – Air takes up space so there is no room for the

water to enter– The water pressure compressed the air, allowing

some water into the glass– When the air pressure in the glass equalled the

pressure exerted by the water, no more water could get in and the paper stayed dry

Huff and Puff

• Challenge: blow up the balloon• Materials:– Deflated balloon– Empty, clean plastic bottle

Huff and Puff

• Procedure:– Push the deflated balloon into the bottle and

stretch the open end of the balloon back over the bottle’s mouth

– Without removing the balloon from the bottle, try to blow it up

– Observe and record results

Huff and Puff

• Diagram:

Huff and Puff

• Results:– The balloon can only be slightly inflated

Huff and Puff

• Inference:– The air inside the bottle is taking up space– When you try and blow air into the balloon, it only

inflates a little bit– The balloon inflates slightly because as you blow it

compresses the air inside the bottle

Huff and Puff

• Real life example:– Tube for pulling behind a

boat– Has 2 valves fro 2 separate

bladders– Inflate the inner one first– Why?
