In a 15 minute video, Paul Andersen describes the four major biological molecules found in living things. There are links to two worksheets and a transcript of the videoso you can create your own guided notes for students to complete while watching the video.

Learn about cooking and baking. They are really all about science. Using her kitchen as her laboratory, Camille Schrier, Miss America 2020, explores the power of food and the science of cooking. She dissects what happens when she's in the kitchen preparing two of her favorite foods- eggs and cookies. Join Miss America as she explores the biological building blocks of food and the molecular changes that happen when we cook. Developed for students in grades 6-10.

All cells, organs and tissues of a living organism are built of molecules. Some of them are small, made from only a few atoms. There is, however, a special class of molecules that make up and play critical roles in living cells. These molecules can consist of many thousands to millions of atoms. They are referred to as macromolecules (or large biomolecules).
