4th grade energy

Ryan is eating lunch with a metal spoon. His spoon feels cool to the touch. He thinks about what objects are made out of and how they feel. He decides to place his hands on different spoons at the same time to determine which feels cooler. Which question is Ryan most likely to be able to answer with this experiment?

• How cold are the objects?

• How do different materials compare in how cool they feel?

• Why does the wooden spoon not feel cold?

• Why did the school railing not feel cold?

 Ben plugs in his radio into the wall.  Electricity goes from the outlet, through the cord and to the radio.  What choice best describes the cord?

• conductor

• insulator

• resistor

• current

What statement best describes heat? 

•  Heat moves from the hot object to the cold ones

• Heat only moves by conduction when two things touch.

• Heat moves from the cold object to the hot ones.

• Heat only moves with a fire.

What causes sound energy?

• Heated objects

• Charged particles

• Light energy

• Vibrating objects

What is the ability to cause motion or create change?

• Conduction

• Energy

• Speed

• Temperature

Which of the following is a conductor?

• metal spoon

• Plastic spoon

• wooden spoon

• cotton

What claim could we make from this picture?

• A car needs electrical energy to travel

• When cars travel they always go the same distance and in the same direction.

• When objects collide, they push on each other and can even change motion.

• Speed of cars is always the same.

Jane is doing an experiment with rubber bands. She pulls a rubber band back 1 inch and releases it. She pulls the same rubber band back 2 inches and releases it. She repeats this again pulling back the same rubber band back 3 inches and releases it. What would you expect to happen?

• The rubber band she pulled back 1 inch will go the farthest.

• The rubber band she pulled back 2 inches will go the farthest.

• The rubber band she pulled back 3 inches will go the farthest.

• They will all go the same distance

What type of energy transfer is happening in this picture?

• electrical to light and heat

• electrical to sound

• kinetic to light and heat

• light and heat to kinetic
