How Do We Breathe?

A model is worth a thousand words. Young scholars use what they know about the structure of hydrocarbons to build Lewis dot structures and molecular models. Their tasks include multiple bonds, geometric hybrids, and various isomers.

Food always gets attention! Model atomic structure using fruit loops to represent the subatomic particles. After building models, scholars create ionic bonds using their models. Finally, they use these concepts to create a periodic...

She had a terribly busy day converting oxygen into carbon dioxide; now she just needs a moment to breathe. In the activity, scholars review the function of the respiratory system and discuss bioengineering's role in medicine/health and...

With a partner, youngsters measure their pulse and breathing rates, both at rest and after running in place for a minute. While this activity is not novel, the lesson plan includes a large-scale classroom graphing activity and other...

There's more to that glowing ball of light in sky than most children realize. From the overall structure of the solar system, to the changing of the seasons, these hands-on lessons open the eyes of young scientists to...

Teaching young scientists about atoms is no small task, but this series of worksheets will make it a little easier. From creating and labeling Bohr models, to identifying information provided in the periodic table of elements,...

Atomic models help us visualize the interactions of substances we cannot see. Explore atomic models, specifically Lewis structures, that show valence electrons and their role in bonds.

Using stunning computer imagery, this resource introduces life science learners to cells. It zeros in on the animal cell and the function of its more prominent organelles. Additional support is offered in the form of a self-assessment...

The human body contains more than 200 types of cells, and plants contain many other unique types of cells. While a huge variety of cells exist, they appear to have very similar structures. A detailed presentation describes the structure...

The Next Generation Science Standards list Developing and Using Models as the second science and engineering practice. The video explains conceptual models and the expectations for K-12th grade scholars. It highlights the progression of...
