This is a fun (and moderately challenging) crossword puzzle that would serve as an excellent starter, plenary or in-lesson activity for any radioactivity and isotopes class. This crossword tests students’ knowledge of:
Isotopic/atomic structure
The difference between alpha, beta and gamma radiation
Knowledge of the isotopes of hydrogen (i.e. deuterium and tritium)
Radioactive decay and half-life
The use of Uranium-235 as an electricity generating fuel
This is a lot of fun and my students loved it. If your kids have never learnt anything about the radioactivity and isotopes before, then you could provide the students with a summary to help them as they do the puzzle.
In this pack you get a PPTX (which you can edit), a pdf version and a png of the puzzle itself (in case you want to project it on your interactive whiteboard for students to fill in).
A very clear powerpoint presentation showing the ‘arrows in boxes’ electronic sub shell filling order from hydrogen to krypton. My students find this very helpful and it is useful when printed as a handout. It also shows clearly the incomplete 4s subshell in chromium and copper.
