I'm always looking for interesting and different ways to help my students remember the vocabulary in our science units. I'm pretty sure I do something different for each unit. That can be good and bad. On one hand it is good for them to learn different strategies. But on the other hand, consistency is helpful.
For this unit I broke them up into pairs and had them define and draw a picture of each vocabulary word. I definitely saw some good group work and some not so good group work. But that is part of life and they really do need to learn how to work through that.
