  1. Give me some space… for all my AIR!! Miss Laverty 2012 *Experiments and work sheets adapted from the Edmonton Public Schools curriculum book*

  2. Give me some space… for all my AIR! • If you have a FOIP form to hand in, please place it in the bin • Grab the handout for today’s lesson • Sit down and show me you are ready watch Mr. Butters take a swim!

  3. Diving Paper

  4. Diving Paper • Question: Does air occupy space?

  5. Diving Paper • Materials: • Sheet of paper • A drinking glass • A clear container filled with water

  6. Diving Paper • Procedure • Crumple up the piece of paper and push it into the bottom of the glass • Turn the glass over and push it straight down into the container of water • Observe and record results

  7. Diving Paper • Diagram

  8. Diving Paper • Results: • Air stays in the glass • Some water gets in the glass • The paper does not get wet

  9. 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

  10. Huff and Puff • Challenge: blow up the balloon • Materials: • Deflated balloon • Empty, clean plastic bottle

  11. 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

  12. Huff and Puff • Diagram:

  13. Huff and Puff • Results: • The balloon can only be slightly inflated

  14. 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

  15. 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?

  16. Work Book Organization • Find your workbook • Make sure you have ALL of these documents • Title Page and rubric • Air KWL and Balancing Act • Today’s work sheet If you are missing something please check the bulletin board or grab a fresh copy

  17. Vocabulary • Air: • invisible mixture of gases which make up the Earth’s atmosphere • Mass: • the amount of matter in an object (weight) • Air Pressure: • the force exerted on the surface of objects by the weight of air particles
