Activity #5 Environmental Effects
Students explain the implications of particle theory of The Law of Conservation of Matter for problems of pollution and waste disposal. They describe, in terms of atoms and molecules, what happens to materials when they are dissolved or...
Curated OER
What's the Difference Between Concentration and Solubility?
Students discuss the difference between concentration and solubility as well as examine the difference in a hands-on activity. Using water and table salt, they experiment with solubility. They create different concentrations using water...
Curated OER
Chemistry: Metals and Non-Metals
Learners conduct an experiment to test the reactivity of metals and non-metals. In this chemistry lesson students test metals with different chemicals to observe the reaction. The results are used to categorize the metals.
Curated OER
Off Base
Students study La Chatelier's principle and identify how carbon dioxide may affect pH. For this coral lesson students complete a worksheet on pH and observe a lab.
Curated OER
It's a Gas!
Pupils explore the conditions under which hydrates form. They use the Internet to access information and conduct experiments to examine how the greenhouse effect works.
Curated OER
The Tongue...A Sense of Taste
Students explore the sense of taste. In this biology lesson plan, students consider 4 types of tastes, recognize the papillae or receptors on the tongue, and locate and label the different taste sense organs on the tongue.
Curated OER
Solubility and Chemical Changes in Groundwater
Students test pH of water before and after it travels through different substrates (igneous pebbles and limestone) to detemine how soluble materials can affect groundwater. They answer questions such as: What happended to the pH of the...
Curated OER
Spectrophotometric Determination of an Equilibrium Constant
High schoolers determine the equilibrium constant for a chemical system and use graphing techniques and data analysis to evaluate experimental data.
Curated OER
Let it Grow and See What Happens
Students participate in an experiment in which they try to stop algae from growing. In groups, they develop a hypothesis and test it while making changes to the experiment along the way. They make observations and organize their data...
Curated OER
Water Quality Monitoring
Students study the water quality of a stream in their area, by measuring the temperature, pH, alkalinity and conductivity. They integrate biology with earth science when using the microscope to study the living organisms in the water.
Curated OER
pH Potential
Students experiment to determine the positive and negative impacts of human activities on environmental change. They examine how physical and biological processes such as decomposition affect soil characteristics while looking at the pH...

Selecting Soil Organisms in Compost
Learners conduct an experiment to demonstrate that many of the enzyme systems needed to break down society's wastes exist in nature among the decomposers in a compost pile. They culture compost bacteria on starch agar to examine the...
Curated OER
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...
