This is a great activity to do as either a formative or summative assessment as part of your weather unit. The students demonstrate their understanding of key weather vocabulary by creating an informational hanging sculpture. The students can create a simple mobile in class using supplies provided by you or they can be given this assignment as a project, giving them time to get more creative. I recommend having the students work on completing the graphic organizer element in class in order to ensure the accuracy of the information. You can use the graphic organizer for direct instruction, partner or group work or independent work making this assignment very flexible. With regards to the mobile itself, the students can create a simple one with drawings of the vocabulary terms and the definitions or the students can get more creative and make three dimensional models of the given vocabulary terms.
