Spanish Lesson Plan 

Science Framework


Lesson Overview:  

In this lesson students will review the water cycle by diagramming terminology, learn watersheds to better understand human impacts on water resources, especially through local geography, and graph precipitation data to visualize the severity of California’s drought and become familiar with digital graphing.

Suggested Activities and Learning Objectives by Grade Level:

Essential Question(s) that Connect CCCs and SEPs:

Vocabulary

Water Cycle- The path that water takes as it moves around earth in different states

Watersheds- An area of land from which all the water drains into a single river, lake, or body of water

Precipitation- Any liquid or frozen water that forms in the atmosphere and falls back to the earth

Evaporation- The process of water changing to gas or vapor and floating up into the atmosphere

Drought- When there is a lack of precipitation over an extended period of time

Graphing - A diagram that shows the relationship between two or more changing things

Activity Procedure:

Engage:

Have you ever heard of a drought before? What is a drought (a prolonged period of less than average rainfall). Do we have droughts in California? What patterns have you noticed about when it rains? Does it rain more seasons than other seasons?

Explore:

What would the school garden look like during a drought? Go for a short walk in the garden and look at the plants and animals you see there. How would they be affected by a drought? What would happen if there was less water?

Explain:

Thumbs up/down: Do you think we are in a drought?

Think, Pair, Share: Do you have any ideas of how we could measure how much rain we get?

We use a rain gauge! A rain gauge helps us measure rain in inches. Who can show me what an inch looks like using your fingers? (let all the kids show you an inch).

We use a rain gauge! A rain gauge helps us measure rain in inches. Who can show me what an inch looks like using your fingers? (let all the kids show you an inch). Droughts come in patterns and cycles. Just like how there are times of the year when there is more rain than other times of the year, there are years when we get more rain and years when we get less. As more and more people are using water, droughts become worse. Increased temperatures from climate change also affect rainfall patterns. Scientists believe this could lead to dry years being even drier than they used to be. Before we can figure out what ways to help people prepare for drought, we need to figure how wet or dry a year is compared to other years. Do you have any ideas how we could do this?

Action:

Option 1: ‘Rainfall Graphing’ Students translate precipitation data into a visual point graph on a piece of graph paper. (If graphing seems a bit too advanced for your students, demonstrate on the board, and have students replicate your graph. You can also use a bar graph as that is often easier for kids to understand.)

  1. Review your Garden Agreements
  2. Have students put their names on paper.
  3. Students label graph paper with Inches of Rainfall in (name of town) in (year).
  4. Introduce the concept of graphs and explain what a point graph is. Draw the x and y axes on the board and label with names of the months and numbers in inches starting with 0 at where the x and y axes intersect.
  5. Give some made up examples of rainfall received in a given month and call on students to mark above the appropriate month at the number of inches it rained that month. This helps other students understand what they need to do. Once you feel the students have had enough examples, move on to the next step. (Again, if you need to do the entire activity as a group, continue that way! Or split students into groups of three or four to work together.)
  6.  Mill around and offer support to students who are struggling.
  7. Have students color in below the mark to the bottom creating a bar graph.

You can also use the garden journal for this lesson as a bar graph example and have students copy this method creating a bar graph with local rainfall measurements onto the back of their garden journal .

Reflect:

Why is it helpful to look at a graph instead of just numbers? What pattern(s) did you notice on your graphs? Did some months get more rain and others less? Does it match with the pattern we already discussed about which seasons get more rain? Which month got the least amount of rain? Which one got the most? Do we have enough information from this graph to tell if we are in a drought (We’d need some additional year’s data too). What can we do to save water?
