Rocks and Rocks

For science that week, we learned about rocks. we talked about how to identify rocks, including scratch testing, seeing how it marks things, what kind of cleavage it has, and what kind of crystal formations it has. The crystal part encouraged us to take out our microscope to look at good ol' salt and sugar.

This last week in science we continued to learn about rocks. We learned about igneous, metamorphic, and sedimentary. We even made our own sedimentary rocks from layered plaster mixed with coloured sand in  styrofoam cups that we took off when it was dry.
