Purpose: This challenge is to show scholars what density is and how it is applied to present life surroundings (i.e. Which things on earth are more dense or less dense).

Materials:

    • Aprons
    • A 50 mL beaker
    • Two 400 mL beakers
    • A test tube
    • Test tube holder
    • Red, green, and blue food coloring
    • Sugar
    • Water (from sink)
    • Three pipettes
    • Glass stirrer
    • Paper towels
    • Agent Orange cleaner

Procedure:

  1. Pour 20 mL of sugar into 50 mL beaker.
  2. Pour 10 mL of water into the beaker with sugar. Stir thoroughly with glass stirrer.
  3. Add 3 drops of red food coloring into the sugar water. Stir Thoroughly.
  4. With a pipette, collect the orange-colored solution until pipette is full. Deposit solution into test tube. Repeat collection process 3 more times.

  5. Pour 50 mL of water into 400 mL beaker.
  6. Pour 50 mL of sugar into same 400 mL beaker. Stir thoroughly with glass stirrer.
  7. Add 12 drops of green food coloring into the sugar water consisted in the 400 mL beaker. Stir Thoroughly.
  8. With another, clean pipette, collect the green solution until pipette is full. Deposit solution into the same test tube. Repeat collection 3 more times.

  9. Pour 50 mL of water into the other 400 mL beaker.
  10. Add 2 drops of blue food coloring. Stir Thoroughly.
  11. With final remaining pipette, collect blue solution until pipette is full. Deposit solution into the test tube holding the 2 previous colors. Repeat collection process 3 more times.

  12. Your Density Challenge is complete. Go see Mr. Schnell and show him your creation.
  13. After your presentation, rinse out your beakers, test tube, and stirrer. Dry the rinsed-out materials and place them neatly into their respected storage (glassware= glassware drawer, aprons= apron drawer, other materials= non-glassware drawer).
  14. Wash hands with efficiency (of killing germs, rinsing off any chemicals)
