1. 2 things that determine the amount of energy that arrives at a location
Angle of the sun
Number of hours of Daylight

2. Amount of ENERGY absorbed by earth depends on…
Exp. #1:
Closeness to water
Maritime Vs Continental
Exp. #2: Albedo

3. Instructions: Before you turn on light: 1-4 = Exp. #1 Soil & Water
do pre-lab questions for BOTH experiments,
take first temp reading,
and set up graph.
Get lab stamped before you turn on light.
Do not start timer over each time you read the temp. Let it run for 20 minutes.
Graph as you go! (efficient use of time)
1-4 = Exp. #1 Soil & Water
5-8 = Exp. #2 Light & Dark
Key:
= Water
= Soil
(Degrees Celsius)
Temperature
20 C ….40 C
0 min …. 20 min
Time ( Minutes )

4. Color of Surface

8. Distance from large body of water
Range = Highest – Lowest
Maritime
Continental

9. Distance from large body of water

12. Copy data for the other experiment
