Wetland Water Testing
Students examine the different properties that affect water quality. In this pollution lesson students play a game, complete a hands on activity and computer lab.
Curated OER
The Acid Rain Test
Fourth graders engage in a research project to increase their ability to conduct experiments, interpret data and discuss results in a scientific paper. After doing a lab which simulates effects of acid rain, pairs of students write a...
Curated OER
Discovering Friction
Students watch a demonstration that introduces them to the idea that friction is a force that impedes motion when two surfaces are in contact. They work in groups to experiment with frictional force using a coffee cup on which they alter...

TE Activity: Stream Consciousness
Fourth graders study how environmental engineers monitor water quality. They use environmental indicators to determine the quality of stream water in their area. They count the number of macroinverabrates and use the information they...
Curated OER
Acids and Alkalis
Learners determine and explain the characteristics of alkalis and acids. With their list of characteristics student groups conduct an investigation into whether various household substances are alkali or acid. Their lab findings are...
Curated OER
Organs to Go...
Learners explain the principles of experimental design and reinforce the steps of the scientific method. Each group of students create a "slush" type mixture to store a chicken liver.
Curated OER
Chemical Leavening Agents
Learners examine chemical leavening agents in dough and batters.
