It's a Gas! Or is it?
Examine the effects of temperature and pressure on solubility and the states of matter of ocean water. Learners make inferences about the unique chemistry of ocean water at different depths. They engage in an activity related to...
Curated OER
Electrolysis
Students conduct a series of experiments on water electrolysis. In this chemistry lesson, students explain what happens to the molecules during the process. They cite real world applications of electrolysis.

Isolation of Phytochrome
Why do soybean plants that are planted weeks apart in the spring mature simultaneously in the fall? Four independent activities cover the history of phytochrome research, scientist collaboration, the electromagnetic spectrum, and...
Curated OER
Dinosaur and DNA Days
Biology stars extract DNA samples from beef thymus and then examine its properties. They use enzymes to digest the DNA samples, and then use electrophoresis to separate fragments. Finally, they discuss methods and principles of...
Curated OER
This Life Stinks
Chemosynthetic communities of cold seep areas are considered in this lesson. Working in collaborative groups, marine biology or oceanography learners research and prepare a report about oxidation-reduction reactions involved with...
Curated OER
Introduction to Toxicology
Students explore the science of toxicology and the relationship between a toxic reaction (response) and amount of substance (dose). They observe two demonstrations illustrating the concept of dose-response.
Curated OER
Water: Friend and Foe
Students brainstorm ways to prevent fires from home. In this technology lesson, students create fire-safety posters for their school. They research the internet and explore other resources to get information for the poster.
Curated OER
Scientific Approach to Forest Management
Young scholars use wireless laptop computers to collect, store, communicate, and organize data from the 1999 Jasper Fire area. They collect data in the field and compare it to student-collected data from prior years to develop...
Curated OER
The Dose makes the Poison
Learners investigate the effect of a chemical (they choose) on the germination of seeds. They calculate % chemical concentrations in water, form a hypothesis, and discuss the ethics of using animals in biomedical research.
Curated OER
The Biofuel Project: Creating Biodiesel
High schoolers research about the processing of biodiesel fuels. In this energy lesson, students produce their own biodiesel using used and new vegetable oil. They discuss the environmental and economic benefits of using biodiesel.
Curated OER
Pronoun Reference - Exercise 1
Do your class members need extra practice with pronouns? Learners are directed to read the sample sentences, determine whether the sentences contain pronoun reference errors, and if so, correct the problems they find. A link to an...
Curated OER
Destructive Impact of Environment on Artifacts
Students recognize that artifacts are destroyed over time. In this environmental factors on artifacts lesson plan, students experiment and observe through the microscope to find the environmental impact on artifacts. Students make a...
Curated OER
Pronoun Reference exercise 1
In this pronoun usage worksheet, students read sentences to determine whether the they contain pronoun reference errors and fix any mistakes they find. Students read twenty sentences.
Curated OER
Building A Topographic Model
Pupils visualize, in three dimensions, features represented by contour lines on a topographic map. They see that the different elevations shown on a two dimensional topographic map can be used to build a 3-D model.
Curated OER
Behavior and Properties of Gases
Students convert Celsius to Kelvin temperature. Students conduct three lab experiments, gas law simulations using Internet applets, lectures and demonstrations. The Laws included are Boyle's, Charles, Combined Gas, Ideal Gas, and Gram's...
Curated OER
GM Foods: Are They Safe?
Students examine the process for testing GM foods. They research benefits and hazards of a selection of GM foods. They also create images of new labels and marketing for GM foods.
Curated OER
Phytoremediation
Students participate in a lab designed to facilitate the clean up and remove of substances ranging from heavy metals to dynamite. They focus on the remediation of copper. They discuss their results of this open ended inquiry experiment.
