Day 76: EM Spectrum


Science 8 – Today the class learned about different types of electromagnetic radiation.  Students were split into groups of 3 or 4, and each group was assigned a spectrum to learn about: radio, microwaves, infrared, visible, ultraviolet, x-ray and gamma rays.  Students had two main tasks.  First, they summarized the information in the textbook using a 20 word GIST.  The idea with the gist is that the text is re-written using exactly 20 words. The reason for using a gist is to promote close reading and determining the most important parts of a section of text.  It forces the students to think critically about the text rather than blindly copying words from the textbook to a notebook.

Their second task was to prepare a whiteboard in order to present their findings to the rest of the class.  The whiteboards were completed with varying degrees of success. However, most students learned from the presentations: both the content and with improving presentations.

After class I took the GISTS and copied them to give back to the students.  These gists can help serve as reference material for the students.
