I particularly enjoyed this journal because it represented how to involve all of the 5 E's (engage, explore, explain, extend, evaluate) by asking questions, having discussions, or showing how to direct the students through the lesson. This lesson is for a unit on engineering and has the students use a bimetallic strip as a switch to make their own blinking Christmas lights. It is an interesting hands-on lesson that will really engage the students.

This article gives a great 5E lesson on how blinker lights work using a bimetallic strip. Students investigate blinking lights and regular lights to compare the differences and then go on to explore the bimetallic strip in detail. This is a good lesson to show how engineering leads to innovation.
