Objective: KWBAT explain the impact of human activity on water availability.
Warm Up - Discussing Water Use
As water resource engineers, we’ll keep talking about water use today to help the people of East Ferris. Water is an important resource that people use every day.
resource: a supply of something that is useful

How do you use water in your daily life? (HINT: Think about your day from when you wake up to when you go to bed. How will you use water?)
Remember, East Ferris is on an island, so it is surrounded by salt water in the ocean. The people on Ferris Island need to use freshwater and not salt water for their daily activities, just as you do. So, we need to figure out why they are running out of freshwater.

Criteria For Success (CFS):
- Read title of the graph
- Read the x and y axis, labels, and units
- Read the question
- Use the information from the graph to answer the question
What do you notice about the population (number of people) on East Ferris? (Use the graph above as evidence for your answer).
What do you think the population (number of people) size has to do with the water shortage (not enough water)?
Sentence starter: If there is more people on East Ferris, then __________________
Today, we’ll put together knowledge we learned yesterday with a new text to answer our Investigation Question. We’re going to record big ideas, not small details - let’s practice identifying the difference between a big idea and a small detail quickly.
For the examples below, write Big Idea if the statement was a big idea about water on Earth and Small Detail if the statement was a small detail about water on Earth.
There is not a lot of freshwater on Earth that humans can use.
A lake is an example of a body of water.
We’re going to work on putting together big ideas from TWO sources to come up with a new and better answer to a question.
Question: How can people affect how much freshwater is available?
Read each statement and choose agree or disagree.

Many places on Earth have water shortages.
Read each statement and choose agree or disagree.

Many places on Earth have water shortages.
Check For Understanding: When people use water, what happens to the amount of freshwater available?
When people use water, what happens to the amount of freshwater in reservoirs or lakes?
How could you conserve (save) more water in your everyday life?
Joe lives by the Atlantic Ocean. Kathy lives by Lake Okeechobee.

Who lives next to a freshwater resource - Joe or Kathy?
Joe texts Kathy a picture of the Atlantic Ocean and tells her that his city can get more drinking water because he lives by the ocean and the ocean has more water.
Do you agree or disagree with Joe’s statement
Most of the water on Earth is salt water in the ocean.
People can affect the amount of freshwater that is available.
Places with a lot of rain never have water shortages.
The amount of water in lakes and rivers stays the same over time.
If a place does not have water shortage right now, that means it will never have a water shortage.

Explain why you agree or disagree with Joe’s statement.
