Simulating Microgravity with Buoyancy
How do astronauts know how to live and work in a weightless environment? It doesn't come naturally! Junior physicists conduct experiments to examine the link between buoyancy and microgravity. Each activity illustrates a different aspect...
Curated OER
Seashore Explorers
There are three separate lessons within this resource that can be used together, or that can each stand alone. In the first, five simple activities allow junior scientists to examine the amazing properties of water. In the second, they...

Fossil Fuels (Part I), The Geology of Oil
Junior geologists work through three mini-lessons that familiarize them with the formation and location of fossil fuels. Part one involves reading about petroleum and where it comes from via a thorough set of handouts. A lab activity...
Beyond Benign
The Big Melt: Arctic Ice Caps
Are the Arctic ice caps really melting out of existence? Junior climatologists examine the statistics of ice decline through four math-based lessons. Each activity incorporates data, climate information, and environmental impact into an...

Human Feet Are Strange
Feet are neat! So, if you've already walked the path of examining animal footprints with your class, put them in the shoes of early humans! A well-designed lesson incorporates video, discussion, and hands-on learning to demonstrate how...
Curated OER
Water Density and Stability Lab
Students observe how different water densities and salinity control the depth at which different water masses occur. Submarines are used as a case study. This is a well-designed with an excellent worksheet.
Curated OER
Water Pressure - Observing Water Flow
Pupils discover that pressure increases the deeper the ocean becomes. They determine how water pressure differs at various depths by observing water flow.
Curated OER
"Water, Water Everywhere and None to Drink"
Ninth graders research the importance of maintaining an unpolluted source of water in their community. They brainstorm ideas on what they can do to help the problem. They can also write letters to their local politicians for help.

Souper Wheelies: Recipe Activity
Your special education class can use this simple recipe for more than just cooking. They'll find correctly spelled words, put words from the recipe in ABC order, circle the correct measurement, and identify items that are in recipe by...
Curated OER
Our Water Resources
Students build a model aquifer to study groundwater zones and water table formation. Students use the models to measure the movement of polluted groundwater.
