    • You will take the temperature of the pond in four different places on the pond
    • You add the temperatures recorded and then divide by four.
    • This will give you the Average Temperature
  • 4. Lines of Clarity
    • This tells how clear the water is.
    • Needs two people
    • One holds the tube under water filling the tube with water.
    • When full, put your thumb on the bottom hole and turn upright. Point hole away from you.
    • The other person will look at the top of the tube. The water is let out of the hole until the person looking sees the design on the bottom.
    • Count the lines to the nearest quarter
