This is a revision of the Weight Though the Universe lesson found online from the Eisenhower Regional Consortium for Mathematics and Science Education at AEL (the original document is the first attachment below). We revised the original version to one that uses the CER (Claim Evidence Reasoning) format. We have also included a student note format and a assessment rubric.
