California's Water Problems
UNDER CONSTRUCTION!
Overview of the Water Cycle
First, we want to make sure students understand the water cycle. This video is a basic overview and comes with a worksheet, with time stamps. Watch the video once all the way through, then have kids take out this worksheet and take notes on the second viewing. You can pause the video at the timestamps to ensure they are taking good notes. This website, Nat Geo, has a bunch of Water Cycle Activities, like this one National Geographic has a site for teachers with lots of water activities! Once students have a solid understanding of how water moves around in our world, we need to focus in on California.
"Until the Last Drop" is a great documentary, but is about a hour and a half long. Have students take notes on this sheet. There are five parts to the video and the information is pretty dense. I suggest watching a part per day, and then having students free-write what they learned, what popped into their heads, just increase writing fluency, while having them starting to think about water conservation. I also suggest printing the "Taking Notes" sheet and having them take notes by hand.
When this preliminary cycle is over, I recommend making a chart with the whole class: How do we solve the water problems in California? Just list all the ideas - ridiculous or not, everything has equal value. Later on, when you revisit the chart, you can cross off bad ideas, add new ideas, alter... But, this chart keeps the whole unit in focus. The final writing project is that students make a claim, an opinion, about the best way to solve the water problem in California and back it up with evidence!
Part One: Water is a limited and uneven resource in California
1: View maps and other evidence
In a whole class discussion, show these interactive maps from NASA: Total Rainfall; Snow Cover; or any of these global maps. Have a discussion about what students notice, what they wonder, and how can we solve the water problems in California.
Next, show students WaterEducation.Org and explore with students to see where their water comes from. For example, if you click on "Central Valley" and then scroll until you find the city of Visalia, you will see that Visalia gets about 30% of it's water from ground water and 60% in drought years! In other hand, Avenal gets it's water from reservoirs set up in 1937. This part should be an exploration of the website, whole class.
This website is very important later on to student's research. The objective today is to help students get familiar navigating around.
2: Learn about California's Dams
This part has a couple of objectives: (1) Have students practice reading fluency, (2) get some preliminary information about California's dams (3) learn how Californians try to solve the water problems in the past, which gets students ready for their own final projects.
There are eight dams, eight reading passages, and eight maps. Click here for the Reading Passages on Dam Construction in California. Students in groups of 2 or 3 will be given one of the reading passages. One student will be responsible for making a map of California that shows the outline of the state, the location of major cities and the location of the dam and the path of the river. The rest of the group will be reading their passage aloud to the class. If you have a group of three, two of the students will read the passage aloud, one paragraph at a time. You will notice that some of passages are longer than others. This is for the groups of 3 to have more equal reading opportunities. If you only have groups of two, then one kid does the map and one kid reads aloud.
While these mini-presentation are going on, the rest of the class is the audience. They will be taking notes --> Audience Notes. At the end of eight presentations, the class should have the notes completed and have a nice list of the dams in California.
Videos:
Flood in the Desert (52 minutes) This is the story of when a damn broke in Los Angeles in the 1920s.
Big Dams of the American West (2 minutes)
California's Watershed (25 seconds)
3: Learn about the Larger California
Water Around my House is a worksheet for kids to take home to discover how water is used in their homes.
Analyzing Charts is a second activity to help students understand the water situation here in California. One of the questions requires students to look at their notes they made about the dams and compare the dates of building to the dates of population growth. You also have the option of dividing these charts into groups of three and having students share within a group something they noticed or wondered.
After completing both activities, now is a great time to revisit the chart, "How can we solve the water problems in California?"
4: Learn about Tulare County
If you live in California or Tulare County, specifically, use this link to get a worksheet where kids are doing some Google Earth to find fresh clean water in their communities. This is specific to Tulare County.
Also, California has a very unpredictable cycle of rain and drought, which gets pretty scary sometimes because wells do dry up for years and years, and then overflow in flood years. Check out this interactive map to see how California changes over time! The website have tons of interactive maps to notice: Like worldwide rainfall, worldwide vegetation, snowfall... it's a great resource!
Part Two: Introduce the Writing Project
1. View the Slideshow This slideshow is to introduce the idea to your class.
2. Writing Time: Day One
You can also Water Facts for Opinion Writing along with a writer's notebook just to get the fluency going, just to get ideas flowing. Print the fact sheet for every student. Read it together. Students will choose three sentences to write into a paragraph. In their writer's notebooks, students take those facts that choose and try to compose them into a paragraph. Students should have at least one paragraph. However, students will be given 15 minutes of writing time, so they can keep writing, add more details, elaborate, etcetera.
3. Writing Time: Modeled text or not?
This modeled text is straight from Lucy Calkins. Today, students will read this text together, highlighting expert opinions. This is just a preview day, so students know what an expert is, how to use quotation marks around someone else's words. Later we will explicitly teach it - today is just a preview.
(1) Have students read the text silently for three minutes.
(2) Have students tell a partner what they remembered from the text. (Make a round-robin sharing? Maybe put a chart in front of them and each kid has to write one thing they learned?)
(3) Pass out highlighters and then re-read the text with students so the teacher is modeling fluent reading. During this "shared reading" of the text, students are to highlight the words written by an expert. Then, circle the types of punctuation used to signify the part that was copied from someone else, such as the quotation marks, the commas, the name of the person, etcetera.
(4) Finally, have a mini-discussion about why the author would use an expert in their arguments. You can chart student responses or you can simply discuss. Ask questions like "How is this more persuasive with an expert?" or "How is the argument more powerful with this quotation?" Students should give answers like "Experts are smarter" or "The facts seems more credible when a scientists says them."
Writing Time:
Using the article and their writer's notebook, kids have 15 minutes to write their opinion about it. Is tap water safer? They can list reasons, reference the article. This is a free-write fluency activity, getting their ideas flowing.
4. Writing Time: Day Two
Opinion piece on why California needs more dams and why they don't
4. Claims and Evidence
Sideshow & Worksheet

3. Expert Quote Analysis
This activity requires students to analyze different quotations from different "experts." Students should be aware of what it takes to be an expert. Some quotes are given here with no context, no expert introduced, or an expert, who is not appropriate for the topic, or who says something inappropriate. Some quotes are given with a proper introduction of the expert, and appropriate information for the task. You can have the students cut out and sort, and then glue together and present; you could also have students choose one quote that they use on a freewrite assignment.
Expert not properly introduced, expert not appropriate for topic, expert is outdated, expert is just plain wrong!
Part Three: Effects of Water problems
Solutions:
There are many possible solutions to the problems in California. Some solutions are working very well, some solutions are too expensive, some solutions have not even thought of yet. The idea of this writing assignment is for students to write an opinion piece about one solution: They can write how bad a solution is or how a good a solution is. Students will need to write a claim and support that claim with evidence. This next section will review how to start that final piece of writing.
Step 1:
I suggest starting the class off with a big giant brainstorming list. Now some ideas can be ridiculous, like evactuating Los Angeles and San Francisco. However, that is how brainstorming works: One bad idea can lead to one great idea. Just grab a big sheet of chart paper and just have the kids start listing ideas. When the whole discussion is over you can cross off the bad ideas. Here is a little preview of some ideas if your class needs a push:
Increase water usage prices
Build more dams for water storage
Build an aqueduct
Pump ground water to the surface
Desalinate ocean water
Recycle water & grey water usage
Move Agriculture industry to more wet areas
Use more water efficient watering devices
Use greenhouses more often
Move people out of California (Mass Exodus)
Capture rainwater off roofs
Cloud seeding
Use only biodegradable soap
Water-sharing agreements with other states
