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 the value of teamwork. Learners will model the assembly of the Genesis wafers onto the collector arrays by working in teams. Includes a teacher's guide and students handouts. Video and audio clips are provided. This lesson 9 of... (View More)

This lesson is about data collection. Learners will investigate different methods of sampling in a simulated cleanroom environment. Includes a teacher's guide and students handouts. This lesson 7 of 10 from the Dynamic Design: The Cleanroom module.

This interactive, online activity asks learners to read information and tables to determine the correct sequence of events associated with servicing the Hubble Space Telescope. Students use the clues provided in the text and graphics to organize the... (View More)
