Bozeman

I chose 4-LS1-2 From Molecules to Organisms: Structures and Processes Use a model to describe that animals receive different types of information through their senses, process the information in their brain, and respond to the information in different ways.

SEP: The Bozeman video said that children at this age need to have actual physical models to understand what is being taught. They should construct something or use computer generated models. Even a drawing by the student is okay. The mental image is not enough.

DCI: The idea of sense receptors and how the brain uses that information is important at this level. Reflex and memory reactions are key concepts also. The model could be used to understand where the action is taking place and what is happening.

CCC: The structure of the sense organs needs to be defined and evaluated for their function. Why is the ear shaped the way it is? Why does the tongue have little bumps? The skin can feel so much, why?

I liked the videos very much and will go back to them for information I need while teaching this year.
