This Project can be used to introduce or conclude a unit on Radioactivity. Students work together in groups, each as a representative for a different organization (NASA, WHO, CDC, UN, or the NPSS) with a unique perspective to achieve a common goal: stop the incoming gamma radiation from the 2017 neutron star collision from harming life on Earth. Students get to be real-world problem-solvers while collaborating and conducting their own research to develop a creative solution!
