Join the tree house detectives in learning about the processes of the water cycle, water conservation, water treatment, and water as a limited resource.

Sometimes, despite the best laid plans, the unexpected will occur. Learners witness this firsthand as they carefully design an experiment to determine the time needed for ice to melt in salt water or pure water. They uncover facts not...

What does your class know about GMOs? Are they savvy to selective breeding? Challenge young minds to engineer the greatest crop of all time using a hands-on genetics unit. Learners discover the good and bad details of selective breeding,...

Math rocks! Cavern design teams determine the rankings of rock types based upon desirability points. The points are connected to the properties of the rocks and their usefulness in building a cavern. 

Access countless activities to use in STEM curriculum. This app is a collection of science, technology, engineering, math, and even art ideas are cataloged by topic and easily accessed from one spot. 

To find life on another planet, scientists look for gases (atmosphere), water, and temperatures that are not extreme. In this activity, groups of pupils become "Titan-ians," scientists who want to explore Earth for possible life forms....

The first remote sensors were people in hot air balloons taking photographs of Earth to make maps. Expose middle school learners to space exploration with the use of remote sensing. Groups explore and make observations of a new...

Is cloning good or harmful? Help your class understand the risks and benefits as they read, research, and discuss human cloning. Individuals form teams, research information, and present to the class before concluding with an in-depth...

Unplugging from technology for one day per week will decrease your carbon footprint—are you up to the challenge? Part two in a series of three allows individuals to explore their personal carbon footprints. By first taking a quiz at home...

The Milky Way gets great reviews on Trip Advisor — 100 million stars. The activity allows scholars to rethink their assumptions and prior knowledge. Pupils observe a set of two lights at equal distance and brightness, but they believe...

If a car gets heavier, it goes farther? By running an activity several times, teams experience Newton's Second Law of Motion. The teams vary the amount of weight they catapult off a wooden block car and record the distance the...

A great way to incorporate math into life science, this instructional activity has learners measure migratory routes on a map and calculate the actual distance that shorebirds on the routes would cover. Learners compute the distance...
