Function of Bones

FOCUS QUESTION

What is a purpose of bones?

PREDICTION/ HYPOTHESIS- If bones are strong, then they will protect organs. If organs are soft and squishy, then they will need something to keep them safe. 

PLANNING

Materials: 

Popsicle sticks of different lengths

play dough

sticky tack

First, we molded the play dough into the shape of lungs. 

Next, we built ribs using popsicle sticks. 

Then, we observed our model and thought specifically about what bones do.

DATA

	What they feel like	What their function might be.
Bones	hard	protect organs such as lungs and heart
Lungs	squishy, soft	help us breathe

CLAIMS AND EVIDENCE-I know that hard bones protect our soft organs and keep them safe inside of our body. I know this because we built a replica of ribs protecting lungs and the ribs were hard while the lungs were soft.

CONCLUSION/REFLECTION-  Hard bones protect our soft organs like our lungs that help us breathe.

QUESTIONS
