Rocks in Our Heads

We had a blast at the Buffalo Museum of Science! Our first task was to start KWL charts at the school before the trip – what do we know about rocks, what do we want to know about them (if anything) and what did we learn. (This last one would be filled out at the museum.)
Here’s what some of us wrote:
K W
We know about three types of rock. I want to know more. (Ustath)
We know about sedimentary and metamorphic rocks. (AM)
We know about sedimentary, igneous and metamorphic rocks. I want to know how to identify rocks and minerals. (WOW! – HU)
We know about sedimentary and metamorphic rocks. I want to know if minerals and rocks are the same. (AS)

Ok, here’s what we learned…

“Sometimes rocks are colorful.” (NE) “Sometimes rocks are man-made.” (Ustath) Like this…

“Almandine is a mineral. Copper is a mineral too. Coal is a rock. Impure marble is a rock. Granite is a rock too….” (AS) And obsidian is beautiful…

Good job, 3rd grade. Thank you parents and thank you Buffalo Museum of Science!
