Shadow Chasing
The students compare themselves and their shadows to various objects big and small. Students use their data to set up proportions to solve.

Just Me and My Shadow
Students take measurements throughout the day using a simple sundial called a gnomon. They record the results on a Data Log and convert from English units to metric (S.I.) units. Data points are plotted on the same graph and analyzed.

3-D Cubes
Students investigate cubes. In this geometric solids lesson, students review geometric concepts previously taught, then logon to a computer game in which they find cube figures and identify the shadow of hidden cubes.
