Have students review basic knowledge of conduction, convection and radiation as well as other thermal energy terms such as the difference between conductors and insulators and temperature and heat by playing the prepared thermal energy cootie catcher on page 2. After modeling its use, instead of basic definitions have students then create their own cootie catcher using terms as either the clue or the answer to a self created question (both templates provided). Two additional templates are also provided with inserted text boxes for student digital creation or as differentiation for students with writing disabilities. A great way for students to have fun reviewing content that is limited in depth; introduce the activity having students play the provided versions and then have students spend time playing each others games on the day they are due or before your next test! Works great in preparation for completion of the Thermal Energy Virtual Lab available in my store.
