Suggested Grades
|
K-2 |
Objective
|
Children will discover how snowflakes in nature are really
formed, and recreate this process with paper and glue |
Materials
|
- White paper
- Scissors
- Glue
|
Method
|
- Explain that snowflakes are created by water vapours bumping
into tiny dust particles, which changes the vapour into an
ice-crystal ("sublimation"). This ice crystal then grows by bumping
into other vapour molecules. When it becomes heavy enough, it falls
to the ground as a snowflake.
- Play "Snowflake Game": Split children into two groups- water
vapour and dust particles. Children drift around slowly and
quietly, and when they bump into the opposite (w.vapour or dust
particle) they join hands. Once this occurs, these pairs drift and
the process repeats itself until the whole class is joined to form a
snowflake. (Note: I made the mistake of playing this in the
classroom- Noisy! and lack of space.)
- Making snowflakes: Children first cut out a circle from white
paper (water vapour), then rip and/or cut tiny pieces of paper (dust
particles) to be glued onto the circle.
- You may want to have all the snowflakes join to display as one
BIG snowflake!
