Explore the use of sound in medical treatments - radio waves, ultrasound waves, cancer treatments, and more. Learn about the varied uses of sound as we investigate not only the current medical landscape, but interesting theories of sound and healing.

Sounds are all around us every day. Outside we hear the birds, we listen to all sorts of music, and we talk to our friends. The reason we can do all of this is because sound travels to our ears in waves. Have you ever tried to talk to someone underwater? Why doesn't it sound the same? Let's check out the science behind that phenomenon!

What does it mean to be a radio announcer? How can radio impact a community? Visit with Chris and learn how working at a small radio station in Clinton, Iowa, helps him serve his community.

We will take a deep dive into the world of poo, and see just what it takes to make that waste!

Artificial Intelligence is transforming the future of medicine.. We’ll compare the past, present, and future of technology in medicine and medical engineering. Learn about robot-assisted surgery and how it has the potential to change the future of healthcare. What is next and how will your generation help us?!?

We’ll explore several different types of gears, investigate how gears work together to transfer energy, and invite students to participate in a problem-solving engineering challenge.

What is food justice? Why is it so important to care about other community members having access to culturally-appropriate foods? Learn about our food system in the United States & ways you can help folks facing food insecurity. Discover ways to fight food-related injustices & work with others to advocate for communities lacking access to healthy, fresh, culturally-appropriate foods.
