Skeletons

From PreK on, I refer to the body parts using bones. As my scientists enter the lab, I ask them to sit on their pelvis and place their phalanges in their laps. Third grade students study the skeletal system and are introduced to all the major bones.

Some of the facts we’ve learned about bones:
Bones give us structure and help us stand.
Bones help us move because they work together with muscles.
We are born with 300 bones, but we have 206 bones when we are adults because some fuse together.
Bone marrow is the spongy tissue inside bones that produces blood cells.
The femur is the largest bone and the stapes, in the middle ear, is the smallest bone.
More than half the bones in our body are in our hands and feet.

Creating a pasta skeleton diagram was a fun way to practice the names of the bones! A diagram is one of the non-fiction elements. We will label the following bones next: skull, mandible, clavicle, ribs, humerus, ulna, radius, carpals, phalanges, pelvis, femur, patella, tibia, fibula, and backbone.

Color Changing Milk Investigation

Kindergarten scientists are learning about the Scientific Method.

I dropped red, yellow, and blue food coloring into pie plates filled with whole milk, and the colors didn’t move when my scientists placed a Q-tip in the center of the colors. Then, they dipped another Q-tip into dishwashing soap, placed it between the colors in the pan, and watched the colors explode! Why did that happen? How did we make green, purple, and orange?

When we cleaned up, we discovered that primary colors mixed together make brown.
