This type of energy makes a wind-up toy car move forward when the spring unwinds.
What is mechanical energy?
Pot holders protect your hands from hot pans because they are made of materials with this property.
What is being an insulator?
A bulb will not light unless the electrical circuit is this.
What is closed?
This is the push or pull that can change an object’s motion.
What is force?
A form of energy which our eyes can detect.
What is light energy?
A marching band provides two forms of energy to observers: one from instruments and one from reflected uniforms.
What are light and sound energy?
Plastic, ceramic, and foam cups, this one is the best insulator based on investigation results.
What is the foam cup?
An incomplete path where electricity cannot flow.
What is an open circuit?
This type of force occurs when two surfaces rub against each other and slow down motion.
What is friction?
Energy produced by vibrations.
What is sound energy?
This household appliance uses more energy per year than an oven, according to the energy table.
What is a refrigerator?
Explanation: Based on the energy usage table, the refrigerator consumes more energy annually than the oven.
Which student lists only conductors?

Who is student 2?
This letter of the alphabet most resembles a complete circuit because it forms a closed path.
What is the letter O?
A soccer ball rolling down a steeper ramp moves faster because the ramp increases this downward-pulling force.
What is gravity?
When students want to know how far a cup typically moves after being hit, they should do this to improve their results.
What is repeat the investigation?
How do plants convert energy?
What is light energy?
Explanation: Photosynthesis transforms light energy into chemical energy stored in glucose.
Electrical plugs use metal prongs and a plastic covering because metal conducts electricity and plastic does this.
What is insulate / prevent electric shock?
A load in a circuit that lights up when electricity flows through it.
What is a bulb?
Which group designs an investigation to test friction?

Who is group 3?
Plants convert light energy into this type of stored energy during photosynthesis.
What is chemical energy?
Bonus
This scientific law states that energy cannot be created or destroyed, only transformed.
What is the Law of Conservation of Energy?
A conductor that carries electricity.
What is a wire?
What would happen if the circuit was opened at point A?

Bulb 1 would go out, and Bulb 2 would stay lit.
When a roller coaster goes down a hill, potential energy turns into this type of energy.
What is kinetic energy?
A light bulb turning electrical energy into light and heat is an example of this process.
What is energy transformation?
