States of Matter and Expansion

Comprehension and additional task exercises pages 130 and 131 from Next Page Science KS3 Complete. Accompanying PowerPoint and word searches available for free from the website.
This exercise covers:
• A brief description of the three states of matter alongside a pictorial showing the changes of state with increasing temperature (expansion clearly visible)
• Water as an anomaly: ice (solid) being less dense that water (liquid)
• A pictorial to illustrate this
• The usual expansion with increasing temperature discussed with examples: liquid expansion (use in thermometers), expansion joints on bridges, power line sag during warmer months, rail track gapping
• A planning exercise on how to make a thermometer and calibrate it
• An exercise emphasising expansion with increased temperature but particle size remaining unchanged
• Amazing WHAT? facts
