About the Course

The Edible World

  • Grades 3-4
  • CTY-Level

The saying goes, “You are what you eat,” and in this chemistry class, you’ll learn how true that adage really is. Examine the ways fats, proteins, and carbohydrates fuel our bodies and make energy for everything from taking a breath to reading a book to running a marathon. Through lab experiments and class discussions, examine the composition of familiar foods, consider the chemical reactions necessary to make them, and explore the role foods play in health and disease. Learn about vitamin D deficiency, study the labels of multivitamins, and complete a vitamin C titration to compare the nutritional value of common fruit juices. Analyze the contents of your favorite fast foods and learn about proteins while using a biuret solution to test for peptide bonds. Study freezing-point depression, the periodic table, and elemental properties while making your own ice cream. Keep a food journal, and at the end of the course, build your public speaking skills by giving a presentation about what you’ve learned.

About Science and Engineering at CTY

Explore space and our planet

In our Introduction to Astronomy course, we’ll visit a nearby observatory or planetarium, see what the cosmos looks like through various spectra, and immerse ourselves in the science and technology that bring the universe closer to home. In Marine Ecology, we’ll visit local wetlands and tidepools, observe flora and fauna, collect water samples and analyze them for clues about their health and humans’ impact. And in The Global Environment, we will explore the human impact on our environment and generate proposals for addressing climate change.

Bond over chemistry

Our chemistry courses help you see the world differently, starting at the atomic level. The Edible World gives budding chefs and science lovers a glimpse into the chemical reactions that happen when we make food, and the chemical makeup of meals and treats we eat every day. In our Crystals and Polymers course, we’ll synthesize slime, grow rock candy, and isolate strawberry DNA to learn about the molecular structure of naturally occurring gems and human-produced plastics. In Chemistry in Society, we’ll consider how the chemicals in products can both enhance and degrade the world around us; produce biodiesel in a lab to understand alternative fuels; and prepare aspirin to learn about the healing and toxic properties of pharmaceuticals.
