Ask the class to recall what solar system objects have been studied thus far. Revise the previous lessons on the sun, Earth and the planets. As a class, brainstorm any other objects or celestial bodies in the solar system. Record the students' suggestions on the board.
Introduce the statement to be investigated: The solar system is composed of more than just the sun and planets.
Watch the video Solar System 101 in its entirety (note: content ends at 3:53). Encourage the students to take notes.

Distribute the What About Me? Other Objects and Regions of the Solar System Worksheet. Read through the task with the students and check they understand the instructions. Discuss and demonstrate how to conduct the research.
Monitor and support the students as they work through the activity. The task can be completed by students individually, in small groups or as a jigsaw activity, with research topics either chosen independently or allocated by the teacher.

Gather the class together. Discuss and check the information collected for each of the objects and regions. Refer to the statement being investigated and decide whether it is true or false, using the information collected in the activity to support or refute it.
Add the words asteroid belt, Ceres, Kuiper belt, Pluto and comet to the Solar System Word Wall.
Collect the students’ worksheets. These could be included in a portfolio of work samples and used to assess the students’ understanding of the unit objectives.
