This simple to use and engaging resource provides a useful framework for a lesson on conduction, convection and radiation. Depending on how much time is available to you, I like to demonstrate conduction through particles by inviting my students to stand next to each other, shoulder to shoulder, vibrating slowly. I then “transfer energy” to one of the students, invting them to vibrate faster, knocking the students (particles) on either side of them, transferring the energy on. To help demonstrate convection, I use the potassium permanganate practical. I usually allow the students to carry out a practical on radiation during the following lesson.
