Matter and Energy, Properties of and Changes in Matter: dissolving, melting, freezing, condensation and changes of state.
The Ontario Science and Technology, Grades 1–8 outcome for Grade 5 says: “Matter and Energy, Properties of and Changes in Matter: dissolving, melting, freezing, condensation and changes of state.” This Fieldbook unit teaches it hands-on, with everyday materials and a printable teacher guide and student sheet for every lesson.
Winter Science at Home Grades K–5
Make frost on the outside of a can, race ice cubes with salt and sugar, lift an ice cube with a piece of string, and look inside a real snowflake. Three kitchen-table winter experiments that actually work, with the real science explained for grown-ups.
- Can you make frost in a can? 40 min
Children crush ice, pack it into two cans, add salt to one, and watch water and then frost appear on the outside. They finish able to explain that the water and frost came out of the air, not through the can.
- Why does salt melt ice? 40 min
Children race three ice cubes covered in salt, sugar and nothing, then use a pinch of salt to lift an ice cube out of a glass with a piece of string. They finish able to explain that salt melts ice by mixing into the water, and that it makes the ice colder, not warmer.
