In this activity, students use mathematics to understand tides and gravitation and how gravity works across astronomical distances, using an apparatus made from a slinky, meter stick, and a hook. A description of the mathematical relationships seen... (View More) in the demonstration is included. The resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

GLOBE field protocols and learning activities connected to this chapter are found in the Earth system science section of the GLOBE Teacher's Guide. (View Less)

In this activity, students measure the length of the day using the rotation of the Earth, and discover that the Sun is not exactly in the same place at the same clock time every day, understand that the changes are due to motions of the Earth, and...
