Lesson 1 Student Worksheet Name_______________________________________
Where is Water on Earth?
On your own, fill in the table below with your predictions about how water is distributed on Earth.
Explore:
In your group, you are now going to use a model to represent water distributions on Earth.
The 2 liter bottle represents all the water on Earth, both fresh and saltwater. Fill it with 2,000 mL of water.
As a group, make decisions about how much water to take out of the bottle for each type of freshwater labeled on the cups. What you leave in the 2 liter bottle will now represent the total saltwater on Earth.
Put your water amounts in the table below (column 1). Then calculate the % (column 2).
Compare Your Data to Other Groups:
Before your teacher shows you the actual percentages for each water type on Earth, do a gallery walk to see the similarities and differences between your predictions and the other groups' predictions. Describe a similarity and difference below:
Your teacher will now give you the actual percentages. Fill in the last column on the chart above.
Analyze the Data in the Table:
“Freshwater is limited across the Earth..” What data in the table above would support this statement? _____________________________________________________________________________________

Your Conclusion:
Based on today’s lesson, provide reasoning and evidence to support the following claim:
“It is important to care about our freshwater resources on Earth.”
One of your pieces of evidence should come from the actual data on freshwater above.
