Materials
IT’S A STRETCH
Lesson 1
Lesson Plan
Note: This lesson is to establish the pupils’ prior knowledge, so it is important to not correct them at this
stage.
Introduction:
1. Display page 98 on the whiteboard and ask pupils to think about what is odd about these pictures.
Using a think-pair-share, pupils explain what is unusual about the image based on prior knowledge.
Pupils then share their thoughts as a whole class.
Development:
2. Show pupils a space hopper toy and a hair tie. Select a pupil to demonstrate how each object is
used. Alternatively, display the images on page 99 (the correct objects).
3. In pairs, pupils complete the T-chart on page 100 by viewing a video of a space hopper and a hair
tie in action, then describing the observable properties of each object and how they can change
shape. Pupils explore if each object returns to its original shape or not before answering the
discussion questions on page 100.
Differentiation
• Guided group work can support pupils in discussing the object and how it changes, with the
adult questioning and prompting pupils to create a group T-chart.
• Challenge pupils to write sentences to describe the object and how it changes using scientific
words where they can.
Reflection:
4. Display the T-chart from page 100 on the whiteboard. Pupils share some of their descriptive words
with the class, while the teacher writes the class responses. This is an opportunity to create a word
wall for this unit of work.
5. Discuss the following questions: What kind of materials are used to make things bouncy and
stretchy? Is a piece of wood or a metal ruler bouncy or stretchy? What other words can be used to
describe those objects? Do all objects return to the same shape after they have been changed? Can
all objects have their shape changed?
