About This Topic

Changing Shapes explores the physical limits of solid objects. According to the Year 2 National Curriculum, pupils should find out how the shapes of solid objects made from some materials can be changed by squashing, bending, twisting, and stretching. This moves students beyond seeing solids as 'unchangeable' and helps them understand the concept of flexibility and elasticity.

This topic is highly tactile. Students learn through direct manipulation of materials like clay, rubber, wood, and metal. They discover that while some materials return to their original shape, others stay changed or even break. This topic particularly benefits from hands-on, student-centered approaches where children can experiment with force and observe the results first-hand.

Active Learning Ideas

Inquiry Circle: The Shape-Shifter Challenge

Give groups a set of items: a sponge, a pipe cleaner, a lump of playdough, and a wooden lolly stick. They must try to squash, bend, twist, and stretch each one, recording which actions work and which don't.

Role Play: Be the Material

The teacher acts as the 'Force' and calls out 'Twist!' or 'Stretch!'. Students move their bodies to show how a flexible material would react versus how a rigid material would stay still. This helps them internalise the vocabulary.

Think-Pair-Share: The Bouncy Problem

Show a rubber band and a piece of string. Ask students why we use rubber for hair ties but string for parcels. They discuss the idea of 'stretching and returning' (elasticity) and share their thoughts.

Watch Out for These Misconceptions

Common Misconception

If a material changes shape, it isn't a solid anymore.

What to Teach Instead

Children sometimes think only liquids can change shape. By squashing a sponge or playdough, they can see that it is still a solid because it doesn't flow or take the shape of a container like water does.

Common Misconception

All 'stretchy' things are the same.

What to Teach Instead

Students may not distinguish between things that stay stretched (like blue-tack) and things that snap back (like a spring). A comparative test helps them identify 'elastic' as a specific type of shape-changing.

Frequently Asked Questions

What are the four ways we can change the shape of a solid?

In Year 2, we focus on four main actions: squashing (pushing together), bending (making it curved), twisting (turning in opposite directions), and stretching (pulling apart).

Why do some things go back to their shape and others don't?

Materials like rubber are 'elastic', which means they have a special way of pulling themselves back together. Other materials, like clay or foil, are not elastic, so once you change them, they stay that way unless you move them again.

How can active learning help students understand changing shapes?

Active learning is essential here because 'squashing' and 'twisting' are physical actions. By actually feeling the resistance of a material or seeing it snap back, students build a 'muscle memory' of scientific properties. This hands-on experience makes the vocabulary much easier to remember and apply to new objects.

Can you change the shape of a rock?

It is very difficult! Rocks are very rigid and strong. You would need a huge amount of force to bend or squash a rock, and it would likely break (snap) before it changed shape. This shows that not all solids can be changed easily.
