Photosynthesis in a Jar
Students simulate Joseph Priestley's experiments using a bell jar. They demonstrate that oxygen is necessary for fire and animals but that given time, plants can create oxygen, allowing fires to burn and animals to breathe.

Is Organic Food Worth the Extra Cost?
Learners calculate the amount of pesticide residue in selected foods for two
pesticides and determine if these levels are safe. They read an article about a
research study looking for metabolites of these pesticides in children. Finally,...

Botanical Discoveries
Sixth graders study the chronology of major events of the Lewis and Clark Expedition. They use primary and secondary resources to obtain information about the plants which were identified by Lewis and Clark.
Curated OER
Solids, Liquids, and Gases
Students explore the three main forms of matter: solid, liquid, and gas. They examine concrete examples of each, using their five senses and "experimenting" to find differences in them. They find pictures of each, cut them out and past...
