Using Hands-On Models To Understand The Chemistry Of Gases

My students need 8 molecular model kits in order to "see" the chemistry of air.

  • $180 goal

This project expired on May 26, 2010.

Hooray! This project is fully funded

My Students

How do the tiniest parts of the universe affect us? How can the smallest molecules find or damage any part of our bodies or cells? My students have not yet discovered why the shapes and sizes of molecules are important, but they have also never built a molecule for themselves.

My students are inquisitive and enthusiastic.

They enjoy learning using audio, visual or physical props. Our school is a public high school with autonomy over the curriculum. Many of the projects in the school are centered around essential questions which asks students to examine and apply concepts taught in the classroom to improve their community.

My Project

The model kits will enable student groups of 2 to build nitrous oxides and other volatile gases present in household cleaners and car emissions. Students will learn how molecules disrupt processes in the brain and somatic cells chemically because the shape and size of poisonous gases are similar to other molecules.

This project is important to enable students to visualize the chemistry of air pollution and critically analyze why and how these molecules affect our environment and our health.

This lesson is a part of investigation that asks " how does air quality affect the health of our neighborhood ?"
