Chemical sciences
LIVING IN A MATERIAL WORLD
Lesson plan
Introduction:
1. As a class, revise materials and their properties by completing the Everyday materials quiz at
. QP PC C
Development:
2. At the front of the class, display items such as a rubber ball, football, soccer ball, Lego® blocks, toy
cars, trucks, play kitchen equipment, plush animals, dolls and toy prams. What materials are theses
toys made from? C
3. In small groups, students sort the items into categories according to material, using the table
on page 55 to list the items. Alternatively, display page 55 on the whiteboard and sort the items
as a class. Question students about toys that have several materials, such as a toy truck which
may appear to be plastic, but may also contain parts of metal. Does each toy only belong in one
category? Which toys can be written in more than one section? Are toys for a baby made from
different materials to toys for older children? Why? PA
4. Each small group chooses one toy that is listed in more than one section and discusses why more
than one material was used to make it. C
5. Students then draw a design for their own toy, labelling which materials it will be made from and
why. The toy should be for a child the same age as them. PA
6. Students record a video showing their design and explaining their material choices. C
Differentiation
• Less capable students can draw a simple diagram and use the video to explain what they mean
in more detail.
• More capable students can elaborate in more detail and construct a more detailed diagram.
Reflection:
7. Groups can rotate to watch each others’ videos. As a class, discuss which materials were used for
most of the designs and why. The group videos can be shared via email or uploaded to a class
website or e-newsletter. E C
