Gnomeo and Juliet Science - Acidic Strength (the pH scale)

This is a lesson on the pH Scale with a theme on Gnomeo and Juliet for a low ability class.

Pupils begin with doing a Sudoku task as they enter the room. They then watch a short video on the pH scale and complete the worksheet, followed by colouring their own pH scale.
There is then a small experiment where pupils determine the pH of different substances. I have left the sheet blank so you can decide on your own substances. I would put the substances in test tubes and let them go around the room and put a drop of Universal Indicator in, or dip Universal Indicator paper in (this way you use less equipment). They can also use Litmus paper and then write a conclusion on the two types of litmus paper.
There is then a short AfL quiz where pupils decide if what is shown is acid or alkali.
Pupils then do a small experiment on how the strength of acid affects limestone, with the pretense of Juliet's tower being made out of limestone and the worry of it dissolving.
The exit ticket involves pupils going around the room and finding examples of different pH's.

There are 2 homeworks available. Both are online experiment. The lower ability homework is changing the pH of soil to change the colour of flowers for Juliet. The second is exploring the amount of hydrogen and how it affects pH.
