Nano What?
The size of a nanoparticle is difficult for pupils to grasp. A hands-on experiment is designed to give your classes perspective. Learners analyze different sports drinks for the content of electrolytes as an introduction to nanoscale....

Aspirin Analysis
Laughter may be the best medicine, but aspirin is also important. Young chemists analyze aspirin tablets using titration in this lab experiment. They then repeat the entire experiment using a different aspirin brand.
Curated OER
Earth Systems
Ninth graders investigate biological systems. They summarize relationships between systems. Students determine how systems relate within the biosphere. They analyze the carbon cycle.
Curated OER
Ice Cream
Students are shown an experiment making ice cream while discovering the freezing point depression. There are questions for students to answer after the demostration.
Curated OER
pH
Students test the pH of various solutions. For this pH lesson, students use litmus paper to test the pH of household solutions. They compare their results with book charts.
Curated OER
Trash Pizza
Students work together to identify items sent to landfills. They summarize percentages of the different items found in landfills. They create a pizza pie graph of all of the components found in landfills.

Rusting-A Form of Oxidation
Students conduct an experiment to observe oxidation. In this chemistry activity, students explain how rusting happens. They rank metals according to their conductivity.
Curated OER
Combating Corrosion
Students perform an experiment to show the chemical reactions that occur when metal corrodes. They apply the results of the experiment to the conservation efforts of art curators trying to restore an ancient Greek bronze. This...

Formation of a Precipitate
Conclude this chemical change unit by having your class combine two liquids that result in formation of a precipitate. The learners discover that chemical reactions result in new materials. Make sure to consider all of the preceding...
Beyond Benign
Daphnia Bioassay LD50
De-icing materials may have a harmful effect on our environment; have your class perform an experiment to test the nature of these effects. Scholars monitor the survival rate of a sample of daphnia as the concentration of a de-icing...
