Sodium Bentonite Swelling Index
Students research the effects of sodium bentonite being combined with water. They discuss the reasons why this chemical is used in landfills. They measure the swelling index of sodium bentonite clay.
Curated OER
Cation Separation and Identification
Students conduct an experiment in which they systematically separate cations from a mixture of substances. They use the following types of reactions to do so: precipitation, acids and bases, oxidation and reduction. They compare a...

Selecting Soil Organisms in Compost
Students demonstrate that many of the enzyme systems needed to break down--and therefore clean up-society's wastes already exist in nature among the decomposers. They select the best starch-munching organisms by altering the environment...
Curated OER
Recycling of Plastics
Students separate plastics according to their densities, develop a method for separation and identify variables in an experiment and a fair test, changing only one variable at a time for a fair comparison. After testing, they develop a...
Curated OER
It's A Gas
Pupils build an organic waste methane generator and learn by running a scientific experiment to see what happens when people alter nature's way of recycling.
Curated OER
The Principles Of Composting
Students put items in a plastic bag and watch the effects of composting. While completing the experiment, students answer questions and ask permission to start their own compost pile at home.
