Best For
This Grade 2 science lesson is about helping students understand how heating and cooling can cause changes in substances like water, butter, and ice cream. Through hands-on experiments, time-lapse videos, and animations, students observe how substances like butter melt when heated and harden again when cooled. The lesson is designed for young learners to explore the concept that heating makes molecules move faster and cooling makes them move slower. It includes discussions, activities, and visual aids to build foundational knowledge about physical changes, setting the stage for deeper science learning in later grades.
NGSS Alignment
• NGSS 2-PS1-4: Construct an argument with evidence that some changes caused by heating and cooling can be reversed and some cannot.
