Changing Shapes of Solids

改变固体形状

Description

Investigate how the shapes of solid objects can be changed by squashing, bending, twisting, and stretching

Mastery Evidence

✓ Demonstrate four ways to change the shape of a solid: squashing, bending, twisting, stretching
✓ Compare how different materials respond to these forces (e.g. clay squashes easily, wood does not)
✓ Explain that the material itself stays the same even when the shape changes

Assessment Prompt

Can your child show you how to change the shape of clay by squashing it, twist a pipe cleaner, and explain that some materials bend while others snap?
