Understanding Energy and Magnetism Concepts

Mr. Kirk introduces a lesson on magnetic fields and potential energy. Students start with a warm-up using a magnetic fields simulation to observe energy changes when magnets repel. They then engage in active reading, focusing on definitions of energy and kinetic energy. For homework, students use the harnessing human energy simulator to create a system demonstrating both potential and kinetic energy, taking screenshots and identifying energy types.

What is the main goal of the warm-up activity in lesson 2.1?

• To measure the temperature change in magnets

• To understand the energy changes when two magnets repel each other

• To set up two magnets to move towards each other

• To observe the attraction between two magnets

In the magnetic fields simulation, what should you do after setting up the magnets?

• Press pause and take notes

• Press run and analyze the energy changes

• Change the magnet positions

• Turn off the simulation

What is energy defined as in the active reading section?

• The ability to make things move or change

• The ability to produce sound

• The ability to generate light
