Term 2, Week 3
27 Apr – 3 May 2026
This week’s topic
Materials Around Us: The water cycle and how substances like ice, butter, wax, ice cream, and chocolate change state
Your Week Ahead
This week your Grade 4s are diving into one of the most relatable topics in the CAPS Natural Sciences and Technology curriculum: the water cycle and how materials change state. Learners will explore how water evaporates, condenses, freezes, and melts as part of a continuous natural cycle. Alongside that, they will look at everyday substances like ice, butter, wax, ice cream, and chocolate to see that water is not the only material that can change between solid and liquid states.
In the curriculum sequence, this topic sits within the broader strand of Materials and their Properties. It builds on what learners discovered in Term 1 about different types of materials and their uses. By connecting the water cycle to familiar substances from the kitchen and everyday life, CAPS encourages learners to see science as something happening all around them, not just in a textbook. This makes the concepts much easier to grasp and remember.
Coming into this week, learners should have a basic understanding that materials can be solids or liquids, and that temperature can cause changes. Most Grade 4s will already have real-world experience with melting ice or chocolate, so you can draw on that prior knowledge to anchor the new vocabulary and scientific ideas. The challenge this week is helping them move from informal observations to using the correct scientific terms like evaporation, condensation, freezing, and melting with confidence.
This Week’s Lesson Plan
This is a 3-lesson week, giving you focused time to build the key concepts step by step without rushing.
Day 1: Introduce the water cycle. Learners explore and label the stages of evaporation, condensation, precipitation, and collection, using diagrams and discussion to connect the cycle to familiar weather experiences.
Day 2: Investigate freezing and melting using water and ice as the main examples. Learners observe and record what happens when ice melts and when liquid water freezes, practising the use of scientific vocabulary in context.
Day 3: Extend the concept of melting and freezing to other everyday substances including butter, wax, ice cream, and chocolate. Learners compare how different materials change state and consolidate their understanding of this week’s key ideas.
