Science -ENERGY Day 4

Science - ENERGY Day 4

TODAY’S TARGET: Investigate and describe some basic forms of energy, including light, heat, sound, electrical, chemical, and mechanical.​

Multiple Choice

A student rode a skateboard to school. When the student got to school, she was excited to tell her friends that she used mechanical energy on her way to school to day. Which student do you MOST agree with?

• the skateboard uses chemical energy to move

• the skateboard is NOT an example of mechanical energy

• the skateboard IS an example of mechanical energy because wheels are a tool that makes work easier

• the skateboard used mechanical energy because the student was pushing with her leg

​FORMS of ENERGY

​There are forms of energy all around us. Energy is the ability to make change or cause motion. Some of those changes can be fast, such as a car speeding past on the road. Some of those changes can be slow, such as a piece of fruit decaying on the ground.

Multiple Choice

What is mechanical energy?

• The energy of motion
• The ability to cause motion (kinetic and potential energy)
• Stored energy
• How far something goes in a specific time

Multiple Choice

Which of the following is NOT a form of energy?

• Thermal

• Mechanical

• Sound

• Water

​Think of the many ways you use energy every day. Do YOU have enough energy to run across the field in PE? Where does that energy come from? It is stored in the foods you eat. Your body uses that stored chemical energy in your muscles to make you run.

Multiple Choice

Which of the following is NOT an example of chemical energy?

• A glow stick

• A battery

• A rock about to fall off a cliff

• A burning match

Multiple Choice

Light is a form of __________ energy. 

• Sound 
• Electromagnetic
• Fun
• Thermal 

​When you wake up every morning, one of the first things you might do is turn on light next to your bed. The lightbulb uses electrical energy to make light, and a little bit of heat. Some lightbulbs waste a lot of the energy they use making heat: since we turn on the light to produce light energy, that heat energy is wasted! Many things that produce light also produce heat.

Multiple Choice

Which of the following is an example of thermal energy?

• A light bulb

• The movement of a car

• The digestion of food

• Heat from a fire

Multiple Choice

What type of energy do we get from the food we eat?

• light

• thermal

• chemical

• sound

Multiple Choice

Which is not an example of energy causing motion?

• skating down a sidewalk

• sitting at the top of a slide

• running the track quickly

• swimming in the pool

​The engine in the school bus or car that you rode to school today uses chemical energy in the fuel it burns to produce mechanical energy to move the vehicle. Tiny explosions inside the engines produce the power the vehicle needs to move. These explosions also produce light and heat, but because they happen deep inside the motor, we don’t see that light. You can feel the heat from the explosions though: feel the hood of your car the next time you get out after a drive.

Multiple Choice

The engine in the school bus or car that you rode to school today uses _________ energy in the fuel it burns to produce mechanical energy to move the vehicle.

• mechanical

• chemical

• heat

• sound

Multiple Choice

This is the energy of vibrating molecules that move through matter. 

• sound 
• thermal 
• mechanical 
• electrical 

​At school, we use energy all day long. The light from the lights in the ceiling help us to see. The sounds from the speakers in the ceiling help us to hear the announcements, hear the videos we watch, and to hear the teacher teaching. The projectors and computers in the classroom all use light energy to help us see the screen. Even the pencil sharpener use energy to help us keep our pencils sharp. All of these things we use at school use electricity to produce the heat, light, sound, and motion we need during our day at school.

Multiple Choice

Which is NOT a true statement about energy?

• it can change into another form of energy

• it can cause a temperature change

• it can cause movement

• it can be completely used up

Multiple Choice

Energy that does not run out of its supply is called...

• Renewable Energy

• Nonrenewable Energy

• Recycled Energy

• Potential Energy
