A short discussion topic, suitable for upper KS2, linking with the topics plants and living things and habitats. This is a super-close-up photo of a tiny diatom, taken with a powerful microscope. Diatoms live in soil, fresh water and the oceans. They are single-celled algae that collect energy from sunlight through photosynthesis.

This ten-minute activity, linking to speaking and listening, is ideal for use at the beginning of the day or during transition times, such as after lunch. Pupils will be challenged to guess what the image is by answering the questions shown on the first slide of the PowerPoint. This could be done on the whiteboard or through discussion with a partner. Once pupils have finished, click through to the next slide to reveal the answers. This discussion topic is also suitable for year 4, year 5, year 6, P5, P6 and P7.
