El Niño sure creates a stir when it comes around! Why not stir up your earth science class with this data analysis activity that examines the temperature and precipitation over the 2002-2003 water year. A tracking chart is provided...

It's time to go to Mars. Using the provided cards and mat, groups design a mission to Mars. The cards contain information about the different components of the launch and warn about a few mishaps that might occur along the way.

DNA is the code for all biological traits, both plant and animal. Using an exploratory lesson, learners begin to explore the concept of a biological code by decoding word puzzles. They then extract DNA from plant cells using detergent to...

Students identify and explain some caused of endangerment and extinction for species as well as explain the effects of extinction on an ecosystem. Teachers use this lesson plan before teaching students about collecting insects or plants.

Due to surface tension, dew — a liquid, is spherical in shape. Learners explore the properties of liquids in activity seven in this series of 36. Beginning with its basic properties such as boiling point and moving through to surface...

Students design and execute a lab through which they study the distinctions between density, buoyancy, and volume.
