This unit delves into the fundamental science and historical contexts to help students explore the question "How can knowledge gained from the Manhattan Project and the Hanford Site contribute using nuclear technologies to positively impact humanity in the future?."Nuclear Chemistry is a great capstone unit for a standard high school chemistry course in that it is fantastic opportunity for students to explore the crossroads between scientific knowledge and the societal implications of new discoveries. Students will have the opportunity to Delve deep into the science standards while also connecting their learning to what it means for us as a global society.
Start a chain reaction, or introduce non-radioactive isotopes to prevent one. Control energy production in a nuclear reactor! (Previously part of the Nuclear Physics simulation - now there are separate Alpha Decay and Nuclear Fission sims.)

Patterns Chemistry is an instructional resource for a year-long high school introductory chemistry course. It meets many of the physical science standards from the Next Generation Science Standards, as well as some earth science standards.
The Patterns High School Science Sequence (https://hsscience4all.org/) is a three year course pathway and curriculum aligned to the Next Generation Science Standards (NGSS).
Each course utilizes:
- Common instructional strategies
- Real world phenomena
- Design challenges to engage students and support their learning.
