Students searched the school grounds for the "perfect" rock. They each had to find one that would fit into a snack size baggie. Then, the children measured, weighed, float tested, scratch tested, and wrote about their rocks. We finished by putting the class rocks in order from the least mass to the greatest. This was great fun. We had a blast with our new pet rocks. They are in the hallway outside of our classroom- if you come by make sure you check them out!
