Bring scientific investigation to life with this engaging Year 2 Science PowerPoint, designed to help children plan and carry out a simple comparative test as part of the Uses of Everyday Materials unit.

In this practical lesson, children become young scientists as they investigate an important question: Which material is the most waterproof? Using everyday materials including paper, plastic and fabric, pupils make predictions, explore the equipment they will need and discover how to carry out a fair comparison.

The presentation uses clear explanations, real-life photographs and structured activities to introduce scientific vocabulary including waterproof, absorbent, prediction, comparative test and fair test. Children are encouraged to discuss their ideas, explain their reasoning and consider why keeping certain things the same makes an investigation more reliable.

The lesson follows a straightforward teaching sequence, moving from identifying materials and equipment to predicting, testing, observing and drawing conclusions. Sentence starters and visual prompts make the activities accessible to children who need additional support, including pupils with SEND and those developing their scientific vocabulary.

This resource is ideal for whole-class teaching, practical group investigations and teacher-led demonstrations. It can also be used with Keynote and Showbie to support digital learning.
