By Katherine Leonard

​ESS3.2 How do existing and developing technologies that utilize renewable and alternative energy resources compare to each other?

Time to breakdown the Essential Question!

​EQ: How do existing and developing technologies that utilize renewable and

alternative energy resources compare to each other?

• CIRCLE the ACTION word in red

• Draw a blue BOX around the TOPIC (what are we talking about?)

• UNDERLINE the DETAILS in green (what kind?)

• Put a STAR next to the answer expectation (how should we answer?)

Engage: All of these create energy without burning fossil fuels. But do they work the same way or equally well everywhere?

​Turn and talk
1s tell 2s: Which one do you think makes the most energy?

2s tell 1s: Which do you think is new or developing?

Explore: Use the videos on the next few slides to fill in the comparison chart.

​Solar Energy

​Wind Energy

​Hydropower

​Geothermal Energy

​Biomass

​Nuclear Energy

Explain: Read page 260. As we read, underline text that supports the idea that alternative energy reduces levels of greenhouse gases.

Read page 261 - Alternative Sources of Energy
