Science: Human Body

I don't know who is more excited about our new science unit...the students or me! Our focus this week has been to understand that our bodies are made up of many systems. Throughout our study we will learn about each system and how it is essential to human life. Students learned that the organs in all systems are made up of tissues, and tissues are made up of cells.

We are focusing first on the skeletal system. Our work back in the fall learning many of the bones in the body has given us a leg up, no pun intended, on this system. Ask your child about the various parts of the bone; the periosteum, haversian canals, and spongy bone. Quiz your child on the various types of joints: hinge, ball-and-socket, pivot, gliding, and fixed. Later this week we will put a bone in vinegar and will observe how the bone reacts to the mild acid in the vinegar. We'll keep you posted!
