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. https://educationalelixirs.blogspot.com/2023/05/educatninja-logic-gate-kits.html Contents Logic 001 - Introduction to the gates and truth table discovery Logic 010 - Designing and constructing logic circuits Logic 011 - Binary and building a half adder from logic gates Logic 100 - The full adder Logic 101 - The full adder and half adder combined - adding two 2-bit numbers Logic 110 - NAND Universal Gate Challenge
