Energy Effects
Last year you learned about kinetic and potential energy and how they are related. This year, we will be expanding on those ideas by looking at what happens when energy interacts with things around us. You will learn how light waves, sound waves, water waves, and seismic waves affect us everyday.
Introduction
To begin, I want you to review what you learned about energy last year. We have to start with a definition of energy in order to figure out how it affects the world around us. Watch the video below and think about the following questions:
- What is energy?
- What are some different types of energy?
- Can energy be transferred from one form to another? Think of a specific example.
Learning Goals
For this unit there will be five learning goals. Underneath each learning goal you will find activities, videos, homework assignments, and other study materials to help you master that goal.
Energy Learning Goal #1: I can explain the properties and give examples of different types of sound waves.
Sounds are caused by vibrations.
Today we completed a tuning fork lab and realized that all sounds are caused by vibrations. Whenever you hear a sound it is due to something vibrating. As soon as the tuning forks stopped vibrating the sound stopped as well.
Sound waves have properties such as frequency and amplitude. See how they change sounds by playing with the simulation below.
Build Your Own Instrument Assignment
For this assignment students will have to build their own instrument. The project is described below:

When Sound is reflected echoes are created.
Echoes are created when sound is reflected off an object. Click on the link below to explore how echoes are made and why they are important. There is an option on the webpage to have the text read to you. Please feel free to use this feature.

Energy Learning Goal #2: I can explain the properties and give examples of seismic waves and waves on water.
Now that we know about sound waves we will spend some time learning about two other important mechanical waves: seismic waves and waves on water. Watch the video below about earthquakes and how seismic waves travel.

Energy Learning Goal #3: I can describe how nuclear reactions that take place on the sun produce heat and light and provide energy to the earth.
Now we will begin learning about light waves. It's important to know how light waves are created. Light is created in the sun through nuclear fusion. The sun is a giant ball of gas that is made of mostly hydrogen and helium. When two hydrogen atoms in the center of the sun fuse together a helium atom is made. During this process a large amount of energy is released in the form of light and heat. The light then travels to the surface of the sun and then to the earth. Light takes about 8.5 minutes to make the 93,000,000 mile journey from the sun to the earth. On earth only a fraction of the sun's total energy is transformed into heat energy.
Energy Learning Goal #4: I can explain the properties and give examples of different types of light waves.
Light waves are a part of the electromagnetic specturm. None of these types of waves need matter to travel through so they can travel through space.

Energy Learning Goal #5: I can demonstrate how energy can be transferred when it interacts with matter.
Sound waves, seismic waves, water waves, and light waves all interact with matter in different ways. When waves bounce off objects they are reflected. When they are transmitted they go through an object. When they are absorbed they go into an object and are transferred to heat energy. Types of energy can also be transformed from one type to another.
