PH Strips

What is it?
pH strips are pieces of paper coated with chemical indicators that change colour in liquids. The colour shows if a liquid is acidic (like lemon juice), neutral (like pure water), or basic/alkaline (like baking soda).

Where do I use it?

• Brine Generator – Check saltwater solutions while exploring energy production.
• Oilfield Pumping Unit – Test water quality in industrial settings.

Why is it important?
pH is used in science, health, and industry — from testing swimming pools to checking soil for farming. In STEM kits, pH strips show how chemistry links to energy and design.

STEM Skill Focus

• Conduct simple chemical tests safely.
• Record, compare, and analyse real-world chemical data.
