The Great Volume Exchanger...or the Magic Matter Maker ®

After reading "Aquatic Alchemy," an article about recapturing water for reuse when in space, your class will use calcium hydroxide or hydrated lime to purify cloudy water. Geared toward high school chemistry or environmental science...

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...

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...

We know solids have a density we can measure, but what about liquids? Lesson explores this concept and allows scholars to explore the relationship between volume and density. Graphing and analysis questions round out the activity. 

Atoms, elements, and molecules, oh my! Teaching the fundamentals of chemistry to curious sixth graders has never been easier to accomplish. Here is a resource that pulls together everything needed to get them off to a good start,...

The water cycle is one of earth's most easily observable processes, but demonstrating each step within classroom walls can be a challenge. Through a series of videos and quick demonstrations, cover each aspect of the hydrologic cycle in...

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...

To flush or not to flush ... that is the question. Is the wastewater treatment program in most towns and cities really the most efficient way to deal with waste? The fourth installment in a series of seven videos about the world's water...

How can we find volume if it a shape isn't easy to measure? Investigate methods for determining this as the volume of regular and irregular objects is explored in several stations. Learners discover that when the standard formula for...

Learners brainstorm on ways they use water, and where water comes from. They view video, Down the Drain, to gain specific facts about water use, properties of water, problems of water and the water cycle. They perform a lab activity...
