Field study Test

Driving question:

How does the clarity of the water change as it gets colder out?

Hypothesis

As it gets colder outside, the water will get clearer.

1. Collect some water to test in the turbidity tube
2. Make sure you are in a bright area
3. Look down the tube
4. Slowly let water out of the tube
5. As soon as you see the pattern at the bottom, close the clamp to stop the water
6. Record water level using the measurements on the side

Materials:

Turbidity tube

Water from the pond

Constant:

Right at the end of the pond by the fallen tree part is where I’ll get my water

At pond around 3.

Fill the tube with water.

This is my table:

Water turbitity

Date	Trial1	Trial 2	Trial 3	Average of this time	Average of the Averages
