Inquiry in Action: Second Grade Chapter 5 - Heating and Cooling

The first of two lessons in the Inquiry in Action: Second Grade Chapter 5 - Heating and Cooling unit is a hands-on instructional activity that allows learners to experiment with melting and freezing butter to observe changes as substance transitions between liquid and solid form. They also view an animation that describes the molecular structure of the liquid and solid material. In the second lesson, scholars explore the properties of baking powder. Pupils learn that some heat-related changes are permanent. Chocolate chip cookies serve as an example.
