Energy Transfer Review

Energy Transfer Review

Science 4th quarter

What we will do

• We will be working on our review for our science test

• You will work through the question with your team and then select an answer

Multiple Choice

Energy can move from one place to another. Which example shows energy moving from one place to another

• a baseball hits a baseball bat

• a lightbulb stays off

• ice cubes stay frozen in the freezer

• Books sit on a shelf

Multiple Choice

Which statement explains why light from the sun can warm up water in a glass?

• light travels very fast

• light travels in a straight line

• water reflects light energy

• water absorbs light energy

Multiple Choice

a student tried to connect an electrical circuit as shown in the image. The student came across a problem, the lightbulb did not light up. How can the student redesign the electrical circuit so that the lightbulb will light up?

• The student can connect a second battery to the first battery

• The student can replace the wires with thicker wires

• The student can replace the steel nails with aluminum nails

• The student can connect the steel nails with a short piece of wire

Multiple Choice

A teacher creates a quiz game to use in her classroom but needs a method for each team to alert her when they have an answer. For each team, the teacher needs to use a buzzer, a light bulb, insulating wire, and a battery. What is the correct order of the initial and final types of energy in the circuit?

• solar, motion, light

• motion, sound, electrical

• electrical, light, sound

• solar, electrical, sound

Multiple Choice

Working in teams helps to make better products. A scientist who studies converting electricity to heat needed an engineer to help her with a project. Which engineer would make the best teammate on the project?

• An engineer who studies how to store energy

• an engineer who is building a new heating system for houses

• an engineer who is designing a new battery

• an engineer who is designing a new speaker system.

Multiple Choice

The photo shows a laser cutting a sheet of metal as the laser moves from one end to the other. A group of students made a table of examples of different types of energy shown in the photograph. Which answer best completes the student's table?

• The metal turns red

• Pieces of metal hit the floor

• sparks hit the floor

• the laser produces a beam of light

Devices work differently and are designed to serve different purposes. Match the device to how it converts electrical energy to light or sound energy or both!

Open Ended

John and his grandpa were camping. Grandpa took a stick and started rubbing it against another stick really fast, in a circular motion. After a while, the stick started to get hot and smoke came from it. Soon, a fire started from grandpa rubbing the sticks together. Explain the transfer of energy happening in this scenario!
