Energy

Energy 


What do you think of when you think of energy? In the unit, you learned about energy from a physics standpoint, but it is true that energy is talked about in various other ways too. People talk about their levels of energy, or the energy someone else gives off. Basically, energy often refers to something we can't directly see but we can feel and we can be affected by, and often see reactions it causes!  

First, how is your energy today? 

Let's review the different types of energies!



Watch this video to start the review on energy :)

Mechanical Energy 

Mechanical energy is a form of energy an object has because of its motion and position. 

Can you think of an example of mechanical energy? 

Chemical Energy

Chemical energy is a form of energy stored in all matter. Chemical energy is released through a chemical reaction. 

Can you think of an example of chemical energy? 

Light Energy

Light energy is the form of energy that allows us to see things. It travels through waves and bounces off things in our world, making those things visible to our eyes. 

Can you think of an example of light energy? 

Sound Energy 

Sound energy is the form of energy that allows us to hear things. Like light energy, it travels in waves. The waves create sound by making the wind vibrate. 

Can you think of an example of sound energy? 

Thermal Energy 

Thermal energy is the form of energy caused by the movement of particles in matter. Thermal energy often is recognized through warmth or heat. 

Can you think of an example of thermal energy? 

Electrical Energy 

Electrical energy is caused when there is a flow or current of electrical charge. We use electrical energy to power machines. 

Can you think of an example of electrical energy? 

Now that we have reviewed all the types of energy you learned about in the energy unit, let's watch a video about renewable energy sources! 


Renewable energy sources!

Which renewable energy source did you find the most interesting and why? 

Look at the pictures below and classify what type of energy they show! (hint: some pictures show more than one type of energy) 











Now that we have learned about all the different types of energies if you are feeling low energy what is one thing you can do to increase your energy!
