LESSON 6: WHY DO WE HAVE SEASONS? Alway

Learning intention:

To explain how the Earth's tilt leads to seasonal changes

What are the four different positions that the Earth will be in its orbit when it is spring, summer, autumn and winter in the UK?

labelled scientific drawing that includes the Sun Explain to the children that they should use the names of the seasons and the terms 'Earth's orbit', 'Earth's tilt', 'the Sun', 'solstice' and 'equinox'.

Lesson summary:

the Earth's tilt on its axis causes seasonal changes and changes in daylight hours. Also how seasons in the northern hemisphere differ from those in the southern hemisphere and from those in tropical regions.

key information

The Earth is tilted at an angle of 23.5°. This is the reason we have seasons in the UK. The tilt angles Earth's northern hemisphere towards the Sun in the summer and away from it in winter, with midway points in spring and autumn.

Key vocabulary:

autumn, axis, equinox, hemisphere, northern, North Pole, orbit, rotation, solstice, southern, South Pole, spring, summer, sunrise, sunset, temperature, tilt, winter

why do some countries not have the same four seasons as the UK?

for example, Pakistan, Ecuador, Indonesia and Republic of Congo.
