KWL Energy Create a KWL chart to describe
KWL: Energy • Create a KWL chart to describe what you Know, what you Wonder or want to know about energy in the first two columns. You will come back and complete the last column by filling in what you Learned after the activity. What I Know What I Wonder What I Learned
• Energy is the ability to cause changes in matter. • There are many different types of energy • They can convert from one to another
• Types of energy and their Energy Source: 3. Electric energy 1. Sound energy (vibrations) 2. Solar energy (sun) (Mechanical, hydro, solar, wind, etc) 4. Light energy (electricity or sun) 5. Hydro energy (moving water)
6. Mechanical energy 8. Geothermal energy (Heat from Earth’s core) (movement) 7. Wind energy (fast moving wind) 9. Thermal energy (burning fossil fuels)
Alternative Energy • An alternative to burning fossil fuels • doesn’t pollute • comes from clean resources • can be converted into electricity (Some energy falls under this category, can you tell which ones? )
