Isolation of Synthetic Chemicals from Plant Leaves
Students isolate and identify a dye, which represents a synthetic pesticide, from plants.
Curated OER
Water Pollution
Fifth graders observe and record what happens when household products are added to a tank of water to depict water pollution. They brainstorm ideas of how to clean the contaminate out of the water before watching demonstrations of...
Curated OER
The Pure, The Mixture, The Unknown
Ninth graders participate in classroom discussions, demonstrations and hands-on laboratory activities about pure substances and mixtures with a focus on common household materials. They investigate: What is a pure substance? What is a...
Curated OER
Toxicology and Living Systems
Students investigate how toxic chemicals affect biological systems. They determine the toxic dose of a chemical that inhibits seed germination in a Brassica rapa. They investigate the effect of environmental tobacco smoke on human lung...
Curated OER
Through Thick or Thin!!!
Students differentiate between high and low viscosity. Students collect, graph, and interpret data, then quantitatively measure polymer solids. Students experiment with a household example of an emulsion polymer.

Understanding the pH Cycle within the Aquarium
Learners discuss places they have been where the air seemed hard to breathe. They discuss if they could "see" the humidity or smell. Students discuss ways this might relate to the fish in the aquarium. The teacher introduces pH and how...
Curated OER
Water Pollution
Fifth graders investigate how humans pollute the water supply with a number of different contaminates. While working in small groups they examine screening, sedimentation, filtration, and chemical treatments as methods of water treatment.
Curated OER
Toxics Lesson Plan
Young scholars discover that chemicals and toxics are all around us and we can make a choice whether or not to use them.
Curated OER
Electrical Circuits And Switches
Students design and draw circuits with batteries, small light bulbs and common household conductors. They build and test the circuit then modify it so someone who couldn't use their hands could turn the circuit on and off.
Curated OER
Water Pollution
Fifth graders examine what contaminated water looks like, and how it becomes polluted. They examine a teacher demonstration of water is not polluted but does contain rocks and other things that do need to be cleaned out before drinking...
Curated OER
Acid(s)-Base(s) Detective
Students investigate acids, bases, indicators and universal indicators. In this acid and base lesson plan, students test 6 samples with litmus paper and determine if they are acids or bases. They separate out 7 samples using litmus paper...
