The learning connection
Hands-on exploration fosters embodied cognition as learners directly manipulate materials. This concrete experience helps solidify their understanding, making abstract concepts like states of matter more tangible and relatable.
Try it with your learner
1. Gather 5 different substances (e.g., salt, water, rice, air in a balloon, and ice). 2. Sort them into solids, liquids, and gases on a table. 3. Describe one property of each substance (e.g., shape, volume). 4. Discuss how each substance changes with temperature (e.g., ice melts to water). 5. Create a simple chart to record your findings. 6. Share your chart with a family member and explain your classifications.
