Physics roadmap

From mechanics and fluids to waves, optics, electricity, magnetism and quantum ideas.

Mendeleev explains

Start from what you can observe, then connect it to the model scientists use.

Try this

Look for one measurable consequence: a colour change, a temperature change, a spectrum, a pressure, a mass or a time.

Common trap

A model is useful because it explains and predicts. It is not a literal photograph of nature.
