An excellent way to assess or even introduce concepts of circuits, insulators and conductors. Have the students use their books to complete the match-up to later glue into their science journals or hand it out to check if your students can identify the meanings and given examples for the vocabulary words. You can even have them provide/draw a few examples of their own. Make sure you have them explain why. This sheet can also be used as a center. Laminate and cut out the pieces!
