Spheres of Earth Hands-on Lab Report Instructions: In the Spheres of Earth Hands-on, you created terrariums. Record your observations in the lab report below. You will submit your completed report.

Name and Title:

Include your name, instructor's name, date, and name of lab.

Objective(s):

In your own words, what was the purpose of the lab?

Hypothesis:

In this section, please include the if/then statements you developed during your lab activity. These statements reflect your predicted outcomes for the experiment.

Procedure:

Since the procedures are listed in your lab, you do not need to repeat them here. However, explain the materials you chose, write a short summary of what you did, and note if you experienced any errors or other factors that might affect your outcome.

Be sure to identify the test (independent) and outcome (dependent) variables.

Data:

On each day of your investigation, record your observations for both terrariums. Do not lift the lid. Lifting the lid could alter the results.

Day One (starting levels) Container One Container Two
Water Level of Lake

(as measured from the bottom of the terrarium to the top of the water)
Condensation on Lid

(present or not present)
Soil

(Does it look wet, moist, or dry?)
Day Two Container One Container Two
Water Level of Lake

(as measured from the bottom of the terrarium to the top of the water)
Condensation on Lid

(present or not present)
Soil

(Does it look wet, moist, or dry?)
Day Three Container One Container Two
Water Level of Lake

(as measured from the bottom of the terrarium to the top of the water)
Condensation on Lid

(present or not present)
Soil

(Does it look wet, moist, or dry?)

Data Analysis:

Use your data to answer the following questions. Use complete sentences, and be as detailed as possible.

How is the water level different for container one versus container two?
If water evaporated in at least one container, where did it go?
If condensation is present on at least one lid, how did it get there?
How is the soil different for container one versus container two?

Conclusion:

Use your data to answer the following questions. Use complete sentences, and be as detailed as possible.

Describe how the test variable you chose affected the water level in your terrarium.
Was your hypothesis supported by your results or not? Explain how you know.
If you were to repeat this experiment, what would you change?
Based on the test variable you chose, explain a similar condition in the real world and its possible effect. (For example, if the test variable was less water than normal, this would be like a drought in the real world.)
List the five spheres of Earth. Which of them were represented in your terrarium? Explain how they interacted in your model.
