Δράση
step 1
On Post-it notes, students will write down a few actions that consume energy (one action per note).
- Write on the board the types of energy according to the Forms-of-Energy curriculum.
- Students should stick their notes to the board below the type of energy relevant to the action written on the note.
- It's possible that one action can be placed under a few different types of energy; for example, water can be heated with thermal energy, radiation energy, chemical energy, or electrical energy. In order to create variety and avoid repetition, only place actions on the board that have not already been placed.
step 2
Demonstrate energy conversion using heat. Having placed a glass of hot water on the table before the lesson, invite the students to touch the table where the glass had been sitting. Students will feel the heat that has passed to the table.
step 3
Continue the worksheet from the previous lesson, filling in the blank column.
step 4
(Optional) Using the kit, build a flying machine (see resources). Point out the process of energy conversion: twisting the rubber band takes the chemical energy from our muscles and converts it to mechanical energy, which is then converted to gravitational energy as the machine flies upwards.
step 5
Next, students will watch a video of a Rube Goldberg machine (see resources) for inspiration. Students will build a Rube Goldberg machine with at least five energy transitions at home, and make a video that includes an explanation of the energy transitions.
