A huge thank you to Mr. Frank for overseeing a lab while I was away on a WABS professional development field trip to Renton Technical College. Students worked in small groups to complete the lab outlined in the Lesson 50 Worksheet. For future reference, students may also review the Lesson 50 PowerPoint slides that accompany the textbook reading. For homework, students were assigned textbook questions 5-7 from the end of Lesson 50 (or notes on the reading).
