Here is a thorough lesson on safety in the chemistry lab. Chemists review a detailed list of safety rules, draw the layout of the laboratory area to include emergency equipment, identify hazard warnings, and consult the MSDS in order to...

Investigate the properties of rocks and minerals through a rockin' hands-on activity. Learners test rocks for various properties and, using a guide, attempt to identify different samples. They use various properties including hardness,...

Students are introduced to the analysis of health risks in the laboratory, particularly from vapors from organic solvents. They consider quantitative measure of risk such as threshold limit values (TLVs), the amount of the compound that...

Students investigate various chemical reactions when creating mixtures in ziplock baggies. In this chemistry instructional activity, students will recognize various chemical reactions and cite evidence. Safety and assessment strategies...

Students experiment with local lake water to determine the health of the lake waters. They explore the human impact on the lake water, hypothesize and share inferences in a scientific report.

Students explore the process of photosynthesis by identifying chloroplasts and chlorophyll pigments. In a demonstration, they observe a demonstration connecting pigments with sunlight conversion into energy. Using paper chromatography,...
