Forms of Energy (Concept Check)

Identify the relationship between the concepts.

Light energy: sun 

Mechanical energy: _______________

• A. Moon 

  
  

• B. Oven

• C. Windmill

• D. Battery

Bats have an adaptation called echolocation that helps them locate prey. The bat emits a noise that moves through air waves, changing the air pressure around it. When the waves hit an object, they bounce back towards the bat.  The bat’s brain uses the vibrations to calculate  the distance to the object. What kind of energy  is the bat using to locate prey? 

• Thermal Energy

• Sound Energy

• Light Energy

• Electrical Energy

 An example of electrical energy is —

• Cutting paper

• Dusting the television

• Ringing the doorbell

• Playing the drum

How is light energy different from sound energy?

• Light energy moves slower than sound  energy.

•  Sound energy can pass through opaque  objects.

• Sound energy moves faster than light  energy.

• Light energy can pass through opaque  objects. 

 What type of energy is shown in the picture?

• Sound

• Mechanical

• Thermal

• Light

Students explore materials that allow thermal  energy to be transferred. Candles, aluminum  pans, and chocolate chips are used. After  

completing the investigation, students clean the  aluminum pans so that the next class can use  them for the same investigation. Why is it a wise  choice to reuse the aluminum pans instead of  throwing them in the trash?

• It demonstrates following the school safety  procedures

• It demonstrates conservation of 

  natural resources.

• It helps raise money for the school recycling  program.

• It increases the cost of science lab supplies.

When the teacher reviews the student's classification, she is most likely to say ---

• One example of sound energy is classified incorrectly

• Both examples of sound energy are classified incorrectly

• One example of light energy is classified incorrectly

• Both examples of light energy are classified incorrectly

During an investigation of energy forms,  students are instructed to use safe practices.  What is the importance of using safe practices  during a lab investigation?

• To minimize dangerous situations 

•  To communicate conclusions from data

• To evaluate the equipment used

•  To criticize school safety procedures

Old Faithful, a geyser in Yellowstone National  Park, shoots water and steam 56 meters  

into the air. It erupts up to 318,000 liters  

of water approximately every 80 minutes.  

Scientists have recorded temperatures of  

118°C at 72 meters deep and 95°C at the  

opening of the geyser. 

• The solar energy of the water decreases as it  reaches the opening of the geyser. 

• The mechanical energy of the water  

  decreases as it reaches the opening of the  

  geyser.

• The light energy of the water  

  decreases as it reaches the opening of the  

  geyser.

• The thermal energy of the eater decreases as it reaches the opening of the geyser.
