Water Properties and More
Did you know many insects use cohesion or surface tension to walk on water? Using a presentation, scholars learn the more important properties of water. It extends into the concepts of solutions, suspensions, pH, and more.
Curated OER
Water
Students conduct a series of investigations on the unique properties of water. In this general science activity, students explain what causes water's surface tension. They explain the different stages in the water cycle.
Curated OER
Supernova Chemistry
Using spectroscopes, high school astronomy, physics, or chemistry learners observe emission spectra from several different sources. This stellar NASA-produced lesson plan provides terrific teacher's notes and a student handout. Make sure...
