This post discusses an activity I found regarding organisms, specifically the differences between ones with vertebrates and ones without. This activity is a hands-on way for students to classify the differences and understand which group they belong to. As mentioned on the website, this is also a great way for parents to (easily) review what their child has been learning at school. The audience for this activity is targeted at 4th graders and gives insight on the the animals skeleton/bones.
