Teachers and families across the country are facing a new reality of providing opportunities for students to do science through distance and home learning. The Daily Do is one of the ways NSTA is supporting teachers and families with this endeavor. Each weekday, NSTA will share a sensemaking task teachers and families can use to engage their students in authentic, relevant science learning. We encourage families to make time for family science learning (science is a social process!) and are dedicated to helping students and their families find balance between learning science and the day-to-day responsibilities they have to stay healthy and safe.

Sensemaking is actively trying to figure out how the world works (science) or how to design solutions to problems (engineering). Students do science and engineering through the science and engineering practices. Engaging in these practices necessitates students be part of a learning community to be able to share ideas, evaluate competing ideas, give and receive critique, and reach consensus. Whether this community of learners is made up of classmates or family members, students and adults build and refine science and engineering knowledge together.
In today's Daily Do, What do you mean we could run out of water? (aka How can we run out of water?), students engage in science and engineering practices and use cause and effect as a thinking tool to make sense of the phenomenon of running out of a seemingly ubiquitous natural resource - water. Students figure out that this phenomenon is also a human-caused problem to be solved. While students could complete this task independently, we encourage students to work virtually with peers or in the home with family members.
Begin by asking students to think about how they use water. Individually, have students make a list of all ways they use water. Next, have them share their ideas with a partner or small group. Next, prompt students to think about where the water they use comes from. When students are finished, engage them in a whole group discussion to share their ideas.
Students will likely share they use water for many different things including drinking, washing and watering (to name just a few). However, many students do not know where their water comes from and answers here will vary greatly. Some students my just say "the faucet" and others may suggest it comes from a nearby lake, river, or ocean.
Now that students have begun to think about water and where it comes from, ask them to think about the following questions:
Give students time to discuss their ideas in small groups, and then have students share their thoughts around the proposed questions with the class. As students share, record their thoughts on the board or some chart paper.
Tell students to give them a better idea of how we use water and where it comes from, you have a short video clip for them to watch. As students watch the H20: The Molecule That Made Us - Virtual Water video have them document what they notice and wonder.
Ask students to share what they noticed. Students may share the following observations:
Then, ask students to share their questions which may include:
Transition students to thinking about where the water is before it arrives where we need it. From the video, they know that some water come from lakes, but where else does it come from? After some sharing of ideas, ask students if just any kind of water can be used for things like drinking, bathing, watering plants, etc., and have them share their thinking. Answers here will vary, but allow all ideas to be shared without judgement.
Tell students you have another short video you would like them watch about water that will help them answer some of there questions. Prompt students to again write down anything they notice or questions that arise. Play the H20: The Molecule That Made Us - Cracks in the Earth video (below).
Discussion Guidance: Use these discussions as formative assessment opportunities to see what your students know and/or don't know about water, how it is used and where it comes from. At this point it is not necessary to correct any misconceptions or incomplete ideas about water as students will be given opportunities to change their thinking around water during the rest of the Daily Do lesson.
After the video, ask students to share any new questions they may have about what they watched. Student questions may include:
Say, "It sounds like we have a lot of questions about the water we use and where it comes from." Explain that you have a bundle of information for them to explore in order to gather data about water so they will be able to answer some of their questions.
Have students get into their group and assign a different resource to each group member to read or explore.
Have students share what they learned from their assigned reading/interactive with the rest of the group. Then, have groups create a poster of what they have learned about where our water comes from, what we use it for and the affects using water has on the planet. Have students present their posters to the class when they are completed.
Guidance: This activity can be done in several different ways. Another option could be to assign each group the same resource and have them create a poster to share the information with the rest of the class. These resources differ in reading complexity allowing multiple access points.
Transition to evaluating how our thinking about water has changed since the beginning of the lesson. What questions did we have that we are now able to answer through our research? We have figured out:
Next, have students explore the What's Your Water Footprint? calculator to determine their water footprint. Before they start, have them predict their water footprint based on what they have figured out so far.
When students are done exploring their water footprint, have a whole group discussion about what they figured out about their water footprint. Prompt students by asking, "Are you surprised by your water footprint?" and encouraging them to share their thinking.
Have students consider the implications of their water usage by asking them the following questions:
Students can work individually or in small groups to formulate their ideas. Then have them share their ideas in a whole group discussion.
Additional Guidance: Human impact on Earth's systems has becoming increasingly more noticeable. The consumption of fresh water across the globe has altered the biosphere in many different ways. This lesson introduces students to the idea that fresh water is a natural resource that we need to watch and manage carefully to ensure it lasts.
To continue learning about this topic, have students investigate the availability of fresh water worldwide. Consider navigating students to the How do we get drinking water from fog? Daily Do next.
NSTA has created a How can we run out of water? collection of resources to support teachers and families using this task. If you're an NSTA member, you can add this collection to your library by clicking Add to my library (near top of page).
