Students explore salt and fresh water. For this water lesson, students investigate the amount of Earth covered by water. Students compare the amounts of salt water to fresh water. Students create a visual representation to aid...

Need to know where your class' knowledge stands? Use these pre- and post-tests to determine your learners' knowledge about nano membranes and nano filters in relation to the filtering of water, specifically contaminated water.  

Students possible sources of water pollution, and explain the effects that water pollution can have on the food on the food chain. They Name human and other animal (i.e. fish) illnesses that can be contracted from drinking polluted...

This science assignment produced by NASA teaches inquiring minds the distribution of Earth's water. Learners will appreciate and understand the importance of fresh water and how weather and climate affects everything.

High schoolers imagine what their lives would be like if they had no access to potable water and watch a morning news show about the water situation on a Navajo reservation. Groups investigate the policies that lead to the lack of water...

Water, water, everywhere — but will there be enough to drink? Check out these detailed lesson plans to meet NGSS water cycle and CCSS literacy standards in your science classroom. Learners do a close reading of a challenging, poetic text...

Students study the process of water purification and explain why it was important to treat it.  In this water purification lesson students purify drinking water and explain the factors that affect water quality. 

Students become familiar with the water cycle and water issues.  In this water lesson students examine what they can do to protect their water.

The article for this lesson no longer accessible through the links in the lesson plan, but can be found in the National Center for Biotechnology Information website. After reading it, environmental science students answer questions and...

How does San Francisco supply its citizens with enough water, even during a drought? Learn about reservoirs and why desalination could be a good solution with a reading passage about water conservation. After kids finish the...

Young scholars play a game to analyze further the effects of water contamination. In this environmental concerns lesson, students play an online game about water contamination and may visit the additional links to further their studies...

How can climate change affect our water supply? Have kids read a passage about the water cycle and water conservation, which includes six questions that challenge them to use context clues.

As a follow-up from the previous lesson, young environmentalists discuss the benefits of water filtration and whether or not it's the best option. Other alternatives including air stripping, bioremediation, and phytoremediation are...

As an example of nature's water filtering system, young ecologists conduct an experiment in the lab. They construct a funnel out of a plastic bottle, fill it with specified layers of materials that simulate layers of soil, then run muddy...

An educational lesson allows young chemists to test the solubility of different types of salt at various temperatures. Groups create a graph using data from unsaturated, saturated, and supersaturated solutions.

How does dirty water get clean enough to drink? After viewing a PowerPoint that outlines the process water goes through at a water treatment plant, groups work together to design a chlorination chamber for a treatment plant.

Students participate in an experiment about evaporation. In this water cycle lesson plan, students use water, thermometers, and measuring tools to make a puddle and measure the size four times throughout the day. Students discuss their...
