ROUND AND ROUND

Math and science come together in this cross-curricular astronomy lesson plan on planetary motion. Starting off with a hands-on activity that engages the class in exploring the geometry of circles and ellipses, this lesson plan then...

In this round astronomical bodies activity, students use 6 photographs of various solar system bodies to answer 5 questions related to the roundness of these bodies. They create a number to represent the roundness of an object and they...

Students explore natural water sources. In this water sources lesson, students investigate water reservoirs. Students work with sponges to simulate a community's natural water consumption. Students discover how water returns to the...

Students explain the role of different organisms in the food web. In this ecology lesson, students participate in a game to simulate mineral cycling through the web. They discuss the importance of recycling minerals and resources.

Young scholars build a device that captures and carries a pet rat safely back to its cage with out "harming" the rat or themselves. They build and experiment with wind-up or battery operated rat cat toys after predicting the outcome of...

In this wheels and axles instructional activity, students read a 1 page article, make a list of how many objects they can find or think if that uses a wheel or axle and then design their own machine.

Eager ecology learners read about characteristics of the Lake Erie water snake and the round goby fish. They find that the goby is an invasive species, introduced to Lake Erie in 1990, and has since had an impact on the water snake...

If you knew people would pay extra for a bald dragon, could you pick which parents you should breed in order to get the highest number? The unit examines heredity and genetics through breeding dragons, mice, dogs, and tries to figure...

It might seem impossible that with more than 14 million species found on Earth, biodiversity is diminishing—but it's the truth. Young scientists explore how invasive species are so destructive to native biodiversity. They compare...

When you look out to the horizon, the earth looks flat, so how do we know it's round? We learn that gravity pulls planets toward the center and shapes them into the spheres that dominate space. This is a great clip that fully explains...
