Teaching With Potential


Who doesn't love hot cocoa?! Engage your middle school scientists while exploring the effect of temperature (thermal energy) on marshmallows and candy canes in hot cocoa. Students will practice their science and engineering practices skills by making predictions, planning investigations, making observations, analyzing data, drawing conclusions, and they'll love every minute of it! Students will also be exposed to crosscutting concepts by looking for patterns when comparing melting marshmallows (and candy canes if you like) to melting snowmen.

To communicate their learning, students will complete a CER writing activity focused on claims, evidence, and reasoning. There are two formats of writing included and both are Christmas and winter bulletin board-worthy. Also included are two extension writing topics to fit your classes needs.
