Devising a Set of Experiments to Test Water for Dissolved Substances

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...

What is the best way to test water quality? Using plastic bottles, scholars create monitoring sensors to test water quality. Creating three different sensors allows individuals to measure water quality at different water levels.

Sometimes, despite the best laid plans, the unexpected will occur. Learners witness this firsthand as they carefully design an experiment to determine the time needed for ice to melt in salt water or pure water. They uncover facts not...

Should you trust the water you drink every day? The hands-on activity has scholars test water from different sources for contaminants. Pupils perform chemical testing and make conclusions about pH, hardness, iron, chlorine, lead, and...

Can you make a stopped egg spin again without touching it? A Veritasium video attempts to do this using inertia. It discusses the differences between attempts with hard-boiled and raw eggs. It explains the science of inertia and opens up...

Students compare bottled water qualities to water found naturally in a pond habitat. They research their state's laws/regulations in regard to bottled water and study the advertising, cost, and quality of brands of bottled water. They...

Students perform an experiment to measure the density of tap water vs. salt water.

Water is common? Not really! Learn how the polarity of the water molecule gives it tremendous properties that make is quite unique in the universe. Learners will understand surface tension, adhesion, and cohesion, as well as why these...

Go with the flow! The first video of a seven-part series about the Earth's water resources introduces learners to the water cycle. With an emphasis on cause and effect, it presents the information simply through animation. And, with the...
