This activity explores how ancient Sun observers made use of natural and built structures to mark solar alignments observed at different times of the year, particularly around the solstices and equinoxes. In Part 1, the teacher prepares a horizon... (View More)

This experiment is about data collection. Learners will map out the actual placement of wafers on the Geneisis array and look at the finished array frames in order to identify patterns of wafer materials. Includes a teacher's guide and students... (View More)

This experiment is about contaminiation. Learners will model the process of verifying clean on a macroscopic level by using a small Secchi (se-key) disk and will read about how the Secchi disk is used in environmental science and compare this with... (View More)

This lesson is about cost limitations on mission design. Learners will be given a budget of $150,000 and an approved subcontractor list that has a listing of the materials and costs for construction. This is activity 6 of 7 in "Dynamic Design:... (View More)
