Devising a Set of Experiments to Test Water for Dissolved Substances

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

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...

Greenhouse gases affect marine wildlife in life-threatening ways. Through experimentation, your classes explore the acidification of water from the main greenhouse gas carbon dioxide. As they introduce carbon dioxide to water, a pH...

Get three planes to line up safely. Individuals work through a set of problems to eliminate spacing conflicts between three airplanes in flight. The pupils use their knowledge to change the airplanes' speed or route to meet a...

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...

Surface tension helps us perform some simple—but impressive science. The video presents many experiments to briefly explain surface tension. From the surface tension on milk and coffee to water, the experiments demonstrate the strength...

Learners 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...

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...

Water filtration — that's pure genius! Groups test the ability of a water filter to purify water by running chlorine contaminated water through a filter and measuring the chlorine concentrations as they filter the water. They then graph...

We know plants assist in the water cycle, but how do plants get water from the ground into the air? Through a series of demonstrations or labs, scholars observe the movement of water through plants. They microscopically view the cells...
