C2.2: Identify the states of matter, and describe characteristics and…

Solids, Liquids and Gases Grade 5

Where does a puddle go? Why does ice float? A first look at the tiny particles that explain the stuff around us.

• Where does a puddle go? 50–60 min

  Teams race wet paper towels in still air, in wind, in a warm spot and under a cup to find out what makes water disappear faster. They catch the 'missing' water on the inside of the cup and explain evaporation with particles.

• Why does ice float? 50–60 min

  Students compare water before and after freezing: same weight, but more space. They float a block of ice, measure how much sticks out, and use particles to explain why lakes freeze from the top down and fish survive the winter.
