Common Misconceptions: Why We Have Seasons
The Earth is closer to the Sun in summer and farther away in winter
Children naturally apply everyday experience to this idea — when you move closer to a fire or heater, you feel warmer. It makes perfect logical sense to them that the same must be true for Earth and the Sun. This belief is also reinforced because it feels like a satisfying, simple explanation.
How to fix it: Show children a globe and explain that Earth's orbit is nearly circular, so the distance barely changes across the year. Powerfully, point out that Australia and South America experience summer in December — at the same time the Northern Hemisphere has winter — even though the whole Earth is the same distance from the Sun. If closeness caused seasons, everyone would have summer at the same time.
The whole Earth experiences the same season at the same time
Young children tend to think of Earth as one place, especially if they have limited experience of people living in very different parts of the world. Their personal experience of seasons feels universal, so they assume everyone shares it.
How to fix it: Use a simple map or globe to point out Australia, Brazil, and South Africa. Explain that when it is winter and cold in the UK or USA, children in Sydney are heading to the beach. Look up real-time weather in both hemispheres together. This concrete contrast makes it immediately clear that seasons are opposite on either side of the equator.
Seasons are caused by clouds or weather blocking the Sun's heat
Children experience cold, grey, cloudy days and naturally connect clouds with cold weather. Because clouds visibly block sunlight, it is easy to conclude that cloudy skies cause winter rather than the other way around.
How to fix it: Explain that some of the coldest winter days are brilliantly sunny and cloudless, while some hot summer days are overcast. Introduce the idea that Earth's tilt controls how directly the Sun's rays hit a region — using a torch and a flat surface, show how a beam of light spread at an angle covers more area and feels less intense than a direct beam. This is what changes between seasons, not cloud cover.
The Earth's tilt changes throughout the year, sometimes tipping towards the Sun and sometimes tipping away
Children often correctly learn that Earth's tilt causes seasons, but then assume the tilt itself must physically change — tipping one way in summer and the other way in winter. This seems logical because something must be moving to cause the change.
How to fix it: Use a ball and a pencil or skewer to demonstrate that the tilt always points in the same direction in space (roughly toward the North Star). Walk the ball around a lamp to show that as Earth orbits, the same fixed tilt means the Northern Hemisphere leans toward the Sun for one half of the orbit and away from it for the other half. The tilt stays constant — it is the position in the orbit that changes.
