Curated OER
Lotic Environment Lesson Plans
Students create and conduct experiments on a "classroom river habitat." They manipulate the biotic and abiotic factors so that they are able to compare an artificially prepared river model to a naturally occurring lotic ecosystem.
Curated OER
Secret Agents of Dissolved Oxygen
Students determine the changes in different types of water in a sealed container over time. They investigate how to measure dissolved oxygen, temperature, and carbon dioxide with calculator or computer probe-ware. Students determine the...

Escape! Survival of the Fittest Grasshopper
Fourth graders, in groups, design a paperclip grasshopper. They determine its ability to survive a prey by jumping high, far, or with a distracting behavior.
Curated OER
Graphing Your Motion-Day 1
Ninth graders explore the concepts of motion, velocity and acceleration through graphing their own movement using LoggerPro. They become more familiar with the computer technology. Students explore graphing in real time and graph on...
Curated OER
Expensive Choices
Eighth graders work in pairs to discover how to prioritize expenses in a budget.
Curated OER
Ice Melting
Students design investigations to test various materials to prevent heat gain in frozen water. The task assess students' knowledge of scientific inquiry including the following skills: observation, data collection, measurement,...
Curated OER
Mixtures
Students observe that movement of a solute in the solvent increases the rate of dissolution. They demonstrate that when the solute is broken into smaller pieces it dissolves faster.
Curated OER
Greenhouse Gas Lab
Students compare the ability of a sample of carbon dioxide gas to
absorb thermal energy compared to a sample of air. They build a visual representation of the greenhouse effect to illustrate the heat-absorption of
atmospheric carbon...
