Reception Science Lesson – Looking Closely and Noticing Changes
This Reception science lesson on looking closely and noticing changes helps pupils observe how materials behave when heated or cooled. Children investigate real-life materials like chocolate, jelly, dough and paint, building vocabulary and scientific thinking through practical enquiry.
As part of our Reception states of matter science scheme, this EYFS lesson supports observation skills and encourages children to describe what they see using science words such as solid, liquid, melt and change.
What’s included in this Reception science lesson?
- Teaching slides introducing scientific vocabulary and real-world examples
- Chocolate melting observation sheet with recording prompts
- Materials-based enquiry using jelly cubes, cloud dough, chocolate and frozen paint
- Small-group investigation activity with stopwatch timing
- Continuous provision ideas including hot chocolate and jelly making
Scientific enquiry skill
This **Reception science lesson on observing changes** focuses on the enquiry skill of *looking closely and noticing changes*. Pupils compare how different materials melt, mix or change state, developing curiosity and confidence in describing what happens.
