C1 continues their trek through planet earth. Last week we did a project classifying rocks. Students brought in ten rocks from their daily environment. They were given a sheet of A3 paper that had twelve circles. Students took their rocks and classified them on six different dimensions (big/little, heavy/light, rough/smooth, shiny/dull, hard/soft, solid/multicolor). They then recorded how many rocks were in each category.

As a second activity, the students put the rocks in order from largest to smallest. They then used a string to measure the circumference of the rocks. They then order the rocks based on that measurement. Students then compare the order based on sight and on measurement.
