In this black holes activity, high schoolers use a formula for time dilation which causes delays in events that occur near the black hole. They solve 6 problems using the equation.

Tenth graders experiment with detection techniques for black holes by modeling the rotation of galaxies with larger and larger masses in the center. They discover while some events cannot be directly observed they may be observable in...

In this black hole worksheet, students use the equation for time dilation to solve 8 problems including determining the time it takes to receive a GPS signal from space, the time delay for the GPS-Earth system, the distance a radio...

Students investigate color diversity by experimenting with jelly beans.  In this color spectrum lesson plan, students observe colored jelly beans through different filters and light sources to change the existing look of the bean....

Students perform an experiment in which they will use a statistical method called `sampling' to count to a billion (and beyond). Students practice sampling by estimating the number of characters on a page from the classified section of a...

Students experience a positive science experiment and study fundamental concepts of measurement.
