Definitions:


  1.  Anemometer:
  2. Beaufort wind scale:

Anemometer

MATERIALS

  1. 4 dishes 
  2.   2 sticks
  3.   tape
  4.   pencil
  5.   pin

STEPS

  1.   tape 4 dishes to the 2 sticks
  2.   put the pin through the two sticks in the middle
  3.   put the bottom bit of the pin in the rubber bit of the pencil
  4.   go somewhere with a watch and record how much 
  5.   

Groups size: 5 
Roles:
  • Timekeeper
  • Counter
  • Recorder
  • Anemometer Manager
  • Wind Manager
  1. Mount the anemometer in a place that has full access to the wind from all directions.
  2. When the time keeper says "Go", the counter in each group will count how many times the marked cup passes them in one minute and write it down.
  3. Repeat the above step four (4) times and record the number of spins on the chart.

FINDINGS

  • Record how many times it spins and record it in the table below.
  • You will need to time them and count the number of spins.

CONCLUSION:






Bag 1: Normal Water cycle
Bag 2: Water cycle with CO2 added: like Oceans in climate change
Bag 3: Water cycle with ice added: like Antarctica in climate change
