Will this water source support life? Small groups test the chemistry of the water drawn from two different sources. They then compare the collected data to acceptable levels to draw conclusions about the health of the source. The...

From their sweat to the water vapor in their breath, astronauts recycle every possible drop of water while in space. After watching a short video describing the different ways materials are recycled and reused in space shuttles, young...

Environmentalists test stream water for temperature, pH, and turbidity. Each group shares their information and then the class makes an overall evaluation of the water quality. A slide show sets the backdrop for the teaching portion and...

Scholars find Earth won't support humans much longer and need to identify a planet with water to inhabit. They test four unknown samples and determine which is the closest to water. Then they explain and defend their results.

Incorporate reading strategies, math, research, and the scientific method into one lesson about water conservation. After reading a story about a landlady trying to determine how many people are living in an apartment, learners develop a...

Explore the world's water without leaving the classroom! In this second of three uncomplicated but wonderful activities, physical science learners feel the pressure of water. They discover that the deeper the water, the stronger the...

Investigate the amazing ability of plants to filter contaminants from water with this series of in-class demonstrations. After placing six small, potted plants in plastic cups, different solutions and mixtures are poured into them that...

How do scientists determine the best method for removing pollutants from our water sources? Environmental scholars experiment with pollution clean-up options to discover which are the most cost-effective, fastest, and most thorough....

General facts about Earth's water sources, human use, and the water cycle are outlined by this presentation. Slide three has a grammatical error and slide nine refers to the local watershed of the author, so you will need to make a few...

Can the class think like the scientists on the International Space Station? Engineers design, test, collect data, and improve a water filtration device similar to a system found on the ISS. Participants use pH strips, optional...
