This unit focuses on isotopes, nuclear decay, fission, and fusion. Students learn how to identify different types of nuclear decay products and look at real-world applications of radioactivity.
Our host explains that nuclear chemistry is what happens in the nucleus of an atom. This segment also covers the nature of radioactivity and the release of energy as it occurs. The students perform an experiment with a cloud chamber and get to see vapor trails, which are evidence of nuclear decay.
This segment explains how nuclear fission creates new elements. Students also learn about the characteristics of the three particles that result from nuclear decay, alpha, beta, and gamma radiation, and the energy derived from nuclear fission.
Students review results from nuclear decay experiments and learn how the law of the conservation of matter applies to nuclear chemistry. Students also learn what a half-life is, how it can be used to determine the age of a fossil, and how to solve a half-life problem.
This segment explores why some atoms emit radioactive particles, while other do not. We also explore why some elements are radioactive. Our students learn about the immense power of nuclear fusion, which produces the energy from our sun and sustains life, and they participate in a lab activity demonstrating a model of fusion using marshmallows.
In the final segment of this unit, students choose assignments in nuclear chemistry that reflect their learning styles and interests. We also visit an isotope laboratory at Georgia Power to see real world scientists at work as they measure levels of radiation in the environment.
If you’ve got an idea for the next great flavor of Coca-Cola but don’t know what to do with it, we’ve got you covered. We visit the world headquarters of The Coca-Cola Company in downtown Atlanta and talk with a few of their nearly 100,000 employees about what it takes to be one of the most recognized brands on the planet. As it turns out, those high school chemistry classes might come in handy.
Your STEM students haven't been on a field trip in ages and they've had enough! They're taking extreme measures "to compare and contrast the characteristics, composition, and location of comets, asteroids, and meteoroids" by planning an interstellar field trip. Their rocket is almost ready, but they haven't started planning their spacesuits and you're a little worried that they don't fully understand the dangers of space travel. Join GPB Education and an intrepid potato for a STEMonstration about how meteoroids don't play nicely in space and what you can do to save the taternaut!
We travel to Pine Mountain to spin the Fast Forward “Wheel of Information,” where we get all the news on Callaway Gardens and how it came to be. Thanks to the experts, including the manager of the Day Butterfly Center, we get a peek into the fields of zoology and entomology and learn more about butterflies than we ever thought possible. Please take our word for it. Some of it is frass-related. We warned you!
