Simple Science Experiments

  1. 1. Simple Science Experiments Try This at Home Lance Rougeux
  2. 2. Vortex Generator
  3. 3. What do you see inside?
  4. 4. What shape does the air make when it comes out of the bucket?
  5. 5. Air Cannon Vortex Generator
  6. 6. pumpkin lever
  7. 7. Sandwich bag dartboards
  8. 8. Sandwich bag dart boards • Materials – Pint or quart-size plastic bags – Several sharpened pencils – Water – Sink, pan or bucket
  9. 9. What is happening? • Most plastics are made of very long molecules called polymers. • Sandwich bags are made of polyethylene which consists of many polymers forming a web of molecules. • The molecular web, with all its connections, resists being torn.
  10. 10. salt engineering
  11. 11. Salt engineering • Materials – Ruler – Cardboard tube – Tissue paper or wax paper – Rubber bands or masking tape – Table salt – Broomstick
  12. 12. What is happening? • The tiny salt crystals transfer most of the force we apply toward the walls of the cardboard cylinder instead of straight down. • Trusses and beams made for bridges and tall building use similar designs to spread or change the direction of forces and loads.
  13. 13. Take a stab at it
  14. 14. Take a stab at it! • Materials – Potato – Straw
  15. 15. What is happening? • The air trapped inside the straw gives the straw enough strength to penetrate the skin of the potato. • As the straw enters the potato, the potato plug compresses the air inside the straw, increasing the air pressure, and strengthening the straw.
  16. 16. Alka seltzer rockets
  17. 17. Alka Seltzer Rockets • Materials – Film canister with a snap-on lid – Water – Alka-Seltzer tablet
  18. 18. What is happening? • A chemical reaction occurs between the water and the Alka- Seltzer tablet creating carbon dioxide bubbles. • The CO2 gas builds up pressure inside the film canister until the force is so great that it has to escape.
  19. 19. Non-newtonian fluids
  20. 20. Non-Newtonian fluids
  21. 21. Non-Newtonian fluids • Materials – Corn starch – Water – Pan
