Deadline to Retake Energy Resources Summative is Wednesday, 29th
goals of the week:
investigate the methods of thermal energy transfer, including conduction, convection, and radiation
verify through investigations that thermal energy moves in a predictable pattern from warmer to cooler until all the substances attain the same temperature such as an ice cube melting
Monday: When putting in a can of soda into the fridge to make it cold, which method of thermal energy transfer allows this to happen?
Tuesday: none, instead students viewed 2 demos of thermal energy transfer and recorded it in their notebooks.
Wednesday: none, due to taking the DCA
Thursday: Which of the following investigations would be most helpful in allowing students to investigate the process of convection?
- Students crack open eggs on the sidewalk outside of their school at various times during the day and notice the changes in the egg’s color.
- Red hot water put into one side of a container and blue cold water on the other with a divider in the middle separating the two sides. Removing the divider students observe how the two types of water mix.
- Rods of different materials are placed on hot plates and record the temperature of the rods over a period of three minutes.
- Digital thermometers at various distances from a heat lamp so that students can record the temperature of the air at each distance.

Monday- students learned how to take the data from Friday’s Quest for Equilibrium lab and transfer it onto a line graph and my expectations for the conclusion. This lab will be due as a formative on Weds., 29th.
Tuesday- students had watching the 2 demos: convection and radiation. After discussing how thermal energy moved in each demo, they had fun moving about the room as energized molecules. Each student was given an amount of chips and they were to “bump” into each other and transfer some energy, aka a chip. The transfer would be made from the one who had more energy/chips to the one with less. Once the more energized molecule was determined, one chip would be given to the less energized molecule and they’d move on. If the energized molecules were equal, then they were to move on without an exchange. We continued this for a few minutes. When we stopped, we counted our energy/chips and discovered that we had nearly reached equilibrium, the same temperature. This activity in a loose way simulates how thermal energy transfers within the natural world, following this rule that thermal energy moves in a predictable patter, from higher to lower temperature until reaching equilibrium.
Wednesday, students took their thermal energy DCA. For periods 2, 5-7, time permitting they finished their GKWs meant for Monday, 27th.
Thursday, students learned how they did on the DCA and then reviewed for tomorrow’s summative.
Friday, students took their summative over thermal energy transfer.
Prepare for Wednesday’s Thermal Energy DCA and Friday’s Thermal Energy Summative. Use the quizlet, heat is on and rewatch the studyjams over thermal energy which can be found on GC.
