Students took notes from the Lesson 9 PowerPoint, learning about the concepts of atomic mass, protons, and neutrons, and isotopes. Students also learned about electrons and the concept of electronegativity. They then worked together in groups of four to complete the Lesson 9 Worksheet. For homework, students were instructed to complete the worksheet, answer questions 1 and 2 from the end of Lesson 9 in the textbook, and then to read Chapter 10 in the textbook. Notes from the whiteboard are pictured below.
Students continued the process of writing up their egg lab reports using the school Chromebooks. Notes from the white board are pictured below. Students will have one last day to use the Chromebooks tomorrow. Students who finish early should “share” their report, written in Google Docs, with me. In return, I will share access to the student egg lab data from all four of my biology classes (open in Google Sheets). Students should analyze the data for trends, patterns, and consistency, using the spreadsheet to organize the data and calculate average mass from similar experimental conditions.
