I created this worksheet to help with renewable and non-renewable energy vocabulary. First I had each children searching for a type of energy (if you have plenty students, they can work in pairs or just double this). I used a research worksheet that is attached.
After this they needed to write their own definitions and ask their colleagues by theirs.
So this is a collaborative task about renewable and non-renewable energy! :) Regardless, you have an answer key in case you want to do it in a different way.
On the next one they had a vocabulary quiz in which they should write the word that matched with the sentence and also find the response for each definition. It was more for consolidation, once they worked on the concepts previously.
Note: I used this after having them putting the puzzles about renewable and non-renewable energy / resources (check them on my store).
