Structural isomers of hydrocarbons. Students (in groups) are tasked with drawing 16 hydrocarbons on separate cards (given the names). They then group the structural isomers together and name the "parent molecule" before checking their work with an answer key (included).

Students will identify nuclear decay products to complete a maze using a reference table (included). Reference table lists decay type for selected radioisotopes.

Nuclear half-life practice problems. Five short answer, 6 multiple choice. Answer key included.

This activity can be used as a card sort for naming simple hydrocarbons (unbranched alkanes, alkenes, alkynes). My original intention, though, was a game/contest: I give each student a card and have them match with the corresponding name/ structure (I participate if an odd number of students). I time how long it takes my students to do this (twice- I switch their cards for the second trial). Whichever of my classes does it fastest earns something like no homework or bonus points

Worksheet about emission spectra and their relationship with the Bohr Atomic Model.
