Energy in Motion: Moving and Storing
A fun exploration of kinetic and potential energy For Years 2-3 students
What is Energy?
Think about things that move around you What makes things go fast or slow? Where do you see energy every day?
Two Types of Energy
Kinetic Energy = Energy when things are MOVING Potential Energy = Energy that is STORED and ready to move Energy can change from one type to another!
Kinetic Energy Examples
A ball rolling down a hill You running in the playground A swing moving back and forth Water flowing in a stream
Potential Energy Examples
A ball sitting at the top of a slide You standing on a chair ready to jump A stretched rubber band A book on a high shelf
Activity 1: Ramp Investigation
Work in groups of 3-4 Roll balls down different ramps Observe: steep vs shallow ramps Draw what you see happening
Activity 2: Pendulum Fun
Pull the pendulum back (storing energy) Let it go and watch it swing Notice how high it goes each time Record your observations
Energy Changes: What Did We See?
{"left":"Ball at top of ramp has potential energy\nBall rolling down has kinetic energy","right":"Pendulum pulled back has potential energy\nPendulum swinging has kinetic energy"}
Key Words to Remember
ENERGY = the ability to make things happen KINETIC ENERGY = energy when things move POTENTIAL ENERGY = stored energy ready to move ENERGY TRANSFORMATION = energy changing from one type to another
Reflection Time
Can you give an example of kinetic energy? What is potential energy? Where else do you see energy changing? What was your favorite discovery today?
