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
• 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
• 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?
