Objectives:<\/strong><\/h3>\n

Part 1: \u00a0<\/strong><\/h3>\n

Investigate the interactions of liquids and solids. Investigate changes of state.<\/strong><\/h3>\n

Materials<\/strong><\/h3>\n

Per Student or Group:<\/strong><\/h3>\n

4-5 ice cubes<\/strong>
\nsalt in a salt shaker<\/strong>
\nplate or tray to work on (not paper!)<\/strong><\/h4>\n

Key Questions<\/strong><\/h3>\n

Why do the ice cubes stop slipping off when you add salt?<\/strong><\/h4>\n

What To Do<\/strong><\/h3>\n

1. Try to stack ice cubes into a tower.<\/strong>
\n2. Try again\u2014but this time let the ice cubes sit out on a plate for 2\u20133 minutes. Then<\/strong><\/h4>\n

sprinkle lots of salt on the top of each cube before putting the next one on top of it.<\/strong><\/h4>\n

Extensions<\/strong><\/h3>\n

Put a piece of string on an ice cube, then sprinkle it with salt. Wait a few moments, then lift the string. The water should melt then re-freeze, sticking the string to the ice cube.<\/strong><\/h4>\n<\/div>\n<\/div>\n
