Year 2 Animals Including Humans – Basic Needs Lesson 2: Why Do Animals Need Water? Lesson Pack
This Year 2 Basic Needs Lesson 2 why animals need water lesson pack teaches pupils how water supports survival in animals, including humans. As part of the Animals Including Humans – Basic Needs unit, this lesson explores why water is essential for life and why it must be clean.
Pupils investigate why animals need water to survive and discover that clear water is not always safe to drink. Through practical enquiry, they design and build their own water filters using sand, gravel and charcoal, observing how layers help to purify muddy water. This hands-on activity strengthens understanding of survival and introduces simple water purification in Year 2 science.
What’s included in this lesson pack?
- Step-by-step lesson plan with clear teaching guidance
- Interactive Year 2 science PowerPoint slides
- Differentiated water filter investigation tasks
- Practical water purification activity instructions
- Assessment questions and key vocabulary support
What pupils will learn
- Why animals need water for survival
- Why water must be clean and purified
- How simple water filters work
- How to explain the link between water and survival using scientific vocabulary
Working scientifically in KS1
Pupils observe closely, carry out a simple test and evaluate how effective their water filter is. They draw labelled diagrams and explain why layers are used when purifying water.
Ideal for Year 2 science
This differentiated Year 2 science lesson pack combines practical investigation with structured explanation to deepen understanding of water as a basic need before pupils move on to food and survival.
