Sixth graders use the internet to examine the different bodies in space. In groups, they select one project they want to complete and are given a timeline for when the sections are due. To end the lesson, they present their information...

High schoolers examine the use of risk analysis in minimizing the likelihood of unwanted side effects of a new technology. Students discuss risk analysis, practice calculating risk, and explore how decisions are made based on the...

Students investigate how water goes from a solid to a liquid then back again.  In this experimental activity students conduct their own experiment and see how water changes form. 

Students are introduced to both celestial coordinates and to the first rung on the distance determination ladder. They convert spherical coordinates to Cartesian coordinates to construct a three dimensional model of a constellation...

Students examine the checkpoints along the Iditarod Trail. They calculate the distances, mean and medians between each checkpoint. Using the internet, they follow along a virtual trail. They answer questions about when it would be more...

Third graders read books about the moon and discuss its perceived changes as it moves across the sky. They observe the moon over the course of a month and chart their observations. They discuss their observations and conduct further...

Young scholars explore the world of stars. They see that the color of a star tells how hot or cold it is, that stars come in different sizes. and that stars are moving through space. They draw lines connecting start to star.

Students observe the effect of gravity on objects. They use tubing and other materials to simulate a roller caster. Afterward, they create a journal to write their observations and summaries.

In this online interactive history worksheet, students respond to 10 short answer and essay questions about the achievements of Johannes Kepler. Students may check some of their answers on the interactive worksheet.
