Tenth graders research locations of biomes and their barriers. In this biomes lesson, 10th graders examine location, environmental conditions, and species of plants and animals that live in the biome. Students take notes and create a...

Students conduct a series of experiments to explore carbon dioxide properties. In this chemistry activity, students explain the production and uses of this gas. They measure its amount in soda and waste product of yeast.

Students study the concepts of polymerization and the function of crosslinkage.  For this polymer lesson students complete a lab activity and write down their observations. 

Students examine mechanisms behind biological evolution and the theories that feed it, and are able to demonstrate their knowledge of these theories in a story.

Students perform experiments to determine the PH, acidity, and buffering qualities of a lake that make them sensitive to acid deposition.

Students perform experiments measuring water pressure. They record their observations after poking holes in plastic bottles filled with water with the lids on and then off. They discover the role gravity plays in the water flow.

Fourth graders construct mini-ecosystem, pollute the ecosystem, observe, collect, and record data on the effects of these pollutants on their ecosystem, organize data on spreadsheets, create graphs, and design presentations to share with...

Students design a structure capabl;e of holding a textbook. They demonstrate that the weight of a textbook is offset by the normal force exerted on the book by the structure.

Fifth graders identify function of phytoplankton in the biospere by conducting experiments and simulations and reading for information. They detect the presence of phytoplankton in bodies of water by examining ocean in satellite images...
