Did you know the idea for the microwave all started with a candy bar? Inventor Percy Spencer was standing in front of a magnetron when he noticed his chocolate treat was melting in his pocket. When Spencer held a bag of corn kernels next to the magnetron and they started popping, he knew he was on to something. This course will teach you about inventors like Spencer, their creations, and their impacts on our world. If you’re the kind of kid who likes to take things apart to figure out how they work, this is the class for you. You’ll deconstruct household gadgets to understand the science of simple machines, create your own products and apply for mock patents, collaborate with your fellow inventors, work in teams to create hovercrafts or design more effective burglar alarms, and chronicle your progress in a journal. It might even spark an idea for your own groundbreaking innovation.

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.
Meet our instructors and staff
This was my fifth summer working at CTY. I love the culture of CTY. For three weeks, students and staff from all over the world create their own special community unlike anywhere else. I love getting to be a part of that.

Dean of Residential Life and CTY Alum
My favorite thing about teaching at CTY is watching the students' curiosity and excitement lead their learning. It's exciting as an instructor to witness their confidence increase and watch as their 'aha' moments manifest into increased knowledge and mastery of the content.

Being in a fast-paced environment where I can be my dorky self and teach and learn from the students I work with, are a couple of reasons why I am drawn to CTY and keep coming back.
