Apply Scientific Inquiry and Scientific Habits of Mind
High schoolers review the components of the scientific inquiry method. In groups, they develop hypothesis on a variety of different topics and design an investigation or experiment to test it. They share their conclusions with the class...
Mascil Project
Water Quality
How do you prevent the spread of water-borne illness in large public swimming areas? Scholars discover the challenges to identifying safe water through an inquiry experiment. They then produce posters sharing their understanding of water...

Water Quality Tests Explained
Learners define all eight water quality parameters and list at list one source for each of the eight water quality parameters. They determine how each of the eight parameters affect river ecosystems.
Curated OER
Water Quality Tests Explained
Students identify the eight tests done to check for water quality. In this ecology lesson, students explain why it's important to test water in rivers. They explore sources of river water pollution.

The Discovery of Ohm's Law
Students study Georg Ohm and how he changed mathematics with his law. In this experimental evidence and stastics instructional activity students complete an experiment on the characteristics of Ohm's law.
Curated OER
Water Density and Stability Lab
Students observe how different water densities and salinity control the depth at which different water masses occur. Submarines are used as a case study. This is a well-designed with an excellent worksheet.
