Soap and Detergent Chemistry

Soap is made from animal fats and vegetable oils, mixed with a caustic chemical called sodium hydroxide (also known as lye). The sodium hydroxide reacts with the oil to make…

Floating and Sinking: Looking at Density

Density describes how much something weighs relating to its size. For example, a cubic centimetre of cork weighs less (is less dense) than a cubic centimetre of lead (which is…

Ice Cream: Colloidal Chemistry

What is a summer without ice cream cones, or a slice of apple pie without a melting scoop of vanilla ice cream? Though it looks simple – cream, milk, sugar…

Static Electricity: Making Things Stick

Atoms (the tiny building blocks that make everything) contain protons, which have a positive charge, and electrons, which have a negative charge. Some electrons are fixed onto the atoms quite…

Making a Rainbow: Breaking Light Into Colour

Sunlight isn’t just white – it’s actually made of a mixture of different colours. As light travels through water or glass, it changes speed, which makes it bend (see ‘Bending…
