Curated OER
Goobers. Goobers? Goobers!
Students begin the lesson by noting the many ways in which to use peanuts. In groups, they use the internet to research the work of George Washington Carver. They discover the allergies and nutritional information of the peanut and...

Mussel Ecology
Students are introduced to the marine environment of the mussel. The emphasis of the instructional activity is upon what human factors are present to influence the environment in positive and negative ways. They brainstorm in groups in...
Curated OER
Waste Management
Four different activities focus on the amount of trash generated and how humans can better manage waste. Learners analyze two days' worth of household garbage, test materials for biodegradability, and rate recyclability of various...
Curated OER
Enzymatic Action
Students observe how a cell uses an enzyme to rid itself of a poisonous substance by experimenting with hydrogen peroxide, potatoes, liver and carrots. They record the temperature and changes of the hydrogen peroxide as other elements...

Should Populations in an Ecosystem be Restricted?
Fourth graders experiment to determine how overpopulation effects ecosystems specifically plants. For this ecosystem lesson, 4th graders conduct an ecosystems experiment after listening to Claire Daniel's, Ecosystems. They watch a video,...

Micro-Ecosystems
Students create a sustainable, self-contained ecosystem in a ten-gallon aquarium.
Curated OER
Waste Management
Students investigate the amount of trash they generate, the problems that result and possible solutions.They complete four activities regarding household trash, biodegradability, packaging, and recycling.

Glucose Factory
Fourth graders determine, through laboratory activity, the presence or absence of glucose in a variety of plant leaves and stems. They work in groups and perform a three part laboratory which shows them how plants convert sunlighht to food.
Curated OER
Enzymes
Students explore enzymes and what can inhibit and act as a catalyst for them. In this enzymes lesson students complete experiments on enzyme properties.
