A no-prep, 4-lesson science unit on EYFS Understanding the World / KS1 Year 1 Seasonal changes (sunlight and warmth; UK light/heat science is taught from KS2, noted honestly), written for Year 0 (ages 4-5). Phenomenon-first and three-dimensional: every lesson opens with something to wonder about and builds toward the unit’s big question. Open and teach — full teacher plans, projectable slides, three differentiated pupil worksheets per lesson, a complete printable lab pack, a knowledge organiser, and a baseline + end-of-unit assessment.

Big question: How does the Sun warm things, and how can we keep cool?

Lesson outline

1. The Sun warms things
2. Sunny spot, shady spot
3. Build some shade
4. Does our shade keep it cooler?

Pupils will know

• Sunlight warms things up.
• The Sun makes the ground, sand, water and toys warmer.
• A shady place is cooler than a sunny place.
• Shade is made when something blocks the Sun.
• We can build shade, like an umbrella, to keep an area cooler.

Pupils will be able to

• Say what the Sun does to things it shines on.
• Compare a sunny spot and a shady spot.
• Build a simple sunshade.
• Check if the shade keeps a place cooler.
