Essential Understanding

The student knows that matter has physical properties and those properties determine how it is described, classified, changed, and used.

Science Background

Texture from Touch: Scholarpedia (website) - This article discusses many aspects of texture and the science behind our sense of touch.

Assessment Ideas

Create a bulletin board with 10 different materials that have varying textures and label them A - L. Have students classify the objects in their notebooks, and explain their reasoning.
