PR-6171IRE Science A STEM Approach - 1st Class

Unit Overview
Materials
IT’S A STRETCH
Science Learning Concepts:
• Exploring properties and characteristics of common materials in the immediate
environment.
• Knowing that everyday materials can be changed in a variety of ways, especially by
heating, cooling and mixing.
Lesson 1
What are materials and how
do they change?
Lesson 2
How can the shape of an
object be changed? Does it
change back to its original
shape?
Lesson 3
What happens when some
materials are heated?
Lesson 4
What happens when some
materials are cooled?
Lesson 5
What other physical changes
can be made to an object?
Does an object go back to its
original shape after a change is
made or does it stay changed?
Lesson 6
How do materials change
when cooking?
Summative Assessment
Assessing prior learning lesson. This lesson is to
establish pupils’ prior knowledge about materials and
how they change by looking at a space hopper toy
and an elastic hair tie.
Pupils explore shapes made with playdough by
playing a brief challenge game. Pupils then compare
the shapes that can be made with playdough and a
rubber band.
Pupils observe and compare what happens to
playdough and chocolate when they are placed
in an oven, and how cooked playdough can’t
be manipulated in the same way that uncooked
playdough can. Pupils create playdough jewellery
from the hardened playdough balls.
Pupils investigate how water, juice, milk and oil
change when cooled. Pupils take before and after
photographs and record their observations in a table.
Pupils explore what kinds of changes can be made
to a cracker by breaking it in half, cutting it, crushing
it, mixing it with water and then drying it out using a
novelty shape mould. Pupils reinforce the concept that
some objects can be changed and stay changed and
other objects return to their original shape.
Pupils undertake a real-life application of changing
materials by making a cheesecake. This involves
physical processes such as crushing, slicing, mixing,
cooling, warming, whipping and beating different
materials.
Viewing sample
Pupils communicate what they have learnt about how
materials such as a rubber band, water, playdough,
juice and a cracker can be physically changed.

STEM Project
A Chair for a Bear
Based on the book A Chair for Baby Bear, pupils
design and make a chair by physically manipulating
newspaper by rolling, twisting, folding, weaving,
scrunching etc. The chair must be strong enough to
hold a toy bear. Pupils then record a video explaining
what is unique about how they used the newspaper.
