Pebbles, Sand & Silt

We started our last science unit for the year on Monday: Pebbles, Sand & Silt. This week we are focusing on investigating three different rocks: basalt, tuff and scoria.

We learned things about the rocks by:

1. Using our senses

2. Rubbing them together

3. Using a magnifying glass

4. Washing them
