A poster describing what indicators are, how they work, including examples of important indicators and their protonated and deprotonated structures.
Also showing the pH curves and overlaying the indicator colours onto them.
Logic gate practical discovery activity worksheets. Students learn logic through play and physically interacting, connecting and reconnecting the gates. Designed to be used with physical logic gates such as the educat.ninja logic gate kits, but will work with other physical gate kits and online simulators too.
