Quantum physics is the branch of science that explores how the tiniest parts of the universe behave—things like atoms, electrons, and photons (tiny particles of light). Unlike everyday objects, these particles follow strange and surprising rules. For example, a particle might be in two places at once, or its behaviour might change just because it’s being observed. It sounds odd, but these ideas have been tested again and again and are at the heart of how nature really works.

This Q&A sheet is designed to help you confidently support your child’s learning about quantum physics. You don’t need a science background to use it. Each question and answer is written in clear, everyday language, with complex terms explained in brackets. It’s suitable for children aged 8–16 and encourages open discussion, curiosity, and deeper thinking. Whether you tackle a few questions at a time or explore them all in one go, the sheet offers flexibility for your home learning routine.

Quantum physics may seem confusing at first, but it’s full of wonder and possibility. Understanding how the subatomic world works helps explain everything from how the sun shines to how computers and smartphones function. We hope this resource makes the topic accessible and enjoyable for both you and your child.
