How can you tell they’ve got it: Why We Have Seasons?

If they’ve got it, you’ll see things like: Explains that Earth's axis is tilted at about 23.5° relative to its orbit; Describes how the tilted axis causes one hemisphere to receive more direct sunlight in summer and less in winter; Refutes the misconception that distance from the Sun causes seasons by noting Earth is actually slightly closer to the Sun in January. Or just try it together: If your child was asked why the UK is hot in summer but Australia is cold at the same time, could they explain that it's not about being closer to the Sun but about which half of the Earth is tilted towards the Sun?

Why We Have Seasons

Your child can explain why the UK is warm when Australia is cold. It is not about being closer to the Sun. It is which half of the Earth leans towards it.

In curriculum terms

Explain that the seasons are caused by the tilt of Earth's axis during its orbit around the Sun, distinguishing this from the common misconception that seasons are caused by changing distance from the Sun

Builds on

Earth & Space Vocabularyages 8–11Explaining seasons through axial tilt requires 'axis', 'tilt', 'orbit', 'solstice', and 'equinox' vocabulary

Earth's rotation and day/nightages 9–11Explaining seasons via axial tilt builds on understanding Earth's rotation and the orbital geometry of Earth around the Sun

The solar systemages 11–12Knowing the solar system's structure and Earth's orbital path provides context for understanding axial tilt and seasons
