LESSON 3: ENERGY TRANSFORMATIONS
Energy can be transformed from one form to another, which makes things in our world happen. When something or somebody moves or jumps or falls or explodes or breathes or thinks or dances or does anything, it's because energy is being transformed.
Learning Goal: We are learning to identify energy transformations in our environment.
Vocabulary Words:
Energy transformations are when energy changes from one form of energy to another. For example, when you eat a banana, your body transforms chemical energy (stored in the banana) to thermal energy to keep your body warm.
Thermal Conductivity: The ability to transfer heat.

Minds On:
I'm sure you know about the phenomenon that happens when you touch a warm tongue to cold metal on a winter's day (hopefully not from personal experience...) Why does this happen? It's all due to thermal conductivity.
Thermal conductivity is the ability to transfer heat. Your tongue is warmer than the cold metal, so it's heat is transferred to the metal pole, causing the moisture on your tongue to freeze.

Action Item 1: How might this school have prevented students from having their tongues stuck on metal poles, even if they were dared? Consider ways to protect the poles, and make sure to include the words "insulator" and "heat transfer" in your answer.
Action
Action Item 2: Choose one form of energy discussed last class and create a concept map showing how it might be transferred to different forms of energy. You should include at least 4 examples of transformations.
Action Item 3: Revisit your energy comic from last class. Identify all examples of energy transformations evident in your comic (e.g. if you showed yourself eating a sandwich, that would involve chemical energy from the food being transferred into kinetic and thermal energy to help your body do work.)
