Daily Objectives: (1) Define conduction and insulation. (2) Describe energy transfer as atom collisions. (3) Discuss properties of metals based on their ability to transfer heat.
Lesson: (1) Teach students that energy is transferred several way and one of the easiest to observe is atom collisions; this is called conduction. (2) Students do Hot Wire lab using straightened paper clip in place of iron wire. Questions should be answered in writing on lined paper (same paper as last lab questions.) Debrief lab by discussing questions.
Assignment: (1) Complete written questions for Hot Wire lab on lined, loose paper.
(D Block) Next class we will do the "Heat Race lab" in class but we will replace three metal wires with 4 (Cu, Fe, Zn, Al) metal strips. Please write a complete set of lab instructions using the template on this website as your starting point. Adapt the instructions to fit you're using 4 metal strips instead of using 3 metal wires. You can (and should) modify the instructions to obtain the same goal as the original lab using the material you are assigned. Email me if you have any questions. Both students in each pair of lab partners should do this assignment even though you will work together on the actual lab in class. You may not start the lab in class until this assignment is complete and you will lose marks for not being ready at the beginning of class.
(F Block) Next class written answers from "Hot Wire lab" are due in writing. Each student must write their own assignment but lab partners may collaborate to talk about the questions.
