This Chemistry resource is aimed at KS3 (or lower ability KS4). It has 4 group challenges and a whole class challenge at the end. This can be used as an introduction to the Elements and the Periodic Table or at the end of term as a fun revision lesson.
It is a science lesson version of my Escape Room Periodic Table lesson (for the same price) that can be found here:
Lesson Plan (it doesn’t need a lab)
Clues for students to find elements, their symbols and their position on the Periodic Table in terms of periods and groups.
Problem solving challenges
Fun Game of Splat at the end.
It also uses their knowledge of reactivity of groups 1 and 7 for solving some of the clues.
I hope you find this resource useful.
