Students examine the importance of good quality safety gear. In this investigative lesson, students will tests various polymers, collect data, and analyze the data to determine which polymer is best for safety helmets. They will design a...

Students light a LED clock or light bulb using potatoes. They examine how a battery works in a simple circuit. They determine how chemical energy changes to electrical energy while experimenting with potato powered circuits.

Learners use a Colorimetric test to measure pH and gain the importance to life in an aquatic ecosystem pH is. They explore the dramatic effect pH level can have on a water body. Learners test the pH level of many water samples.

Students investigate the relationship between dissolved oxygen and organic materials and aquatic organisms. This is a 3-lesson series in which students explore dissolved oxygen and then design an experiment testing the effects of changes.

Learners define and discuss salinity, conduct classroom experiment to determine salinity of water sample by using hydrometer, record predictions, and demonstrate understanding of how salinity influences object's ability to float in water.

Sixth graders conduct a variety of assessments at a local stream to determine if it is a suitable habitat for salmon. They measure temperature, tubidity, dissolved oxygen, pH levels, bacteria and nutrients. In this unit, 6th graders work...

Pupils work in pairs to design a lever. They conduct experiments using a penny and nickel to explore the uses of a lever.
