Teaching activities
Introduction
Ask children to name some materials (clarify the difference between fabric and
materials). Show the material selection and allow children to handle them. What
are they? Where did they come from? Ensure that children are aware of the
distinction between the name of an object and the material from which it is
made e.g. a glass bottle, a plastic bottle. Emphasise that in this activity
they are focusing on materials.
Classwork using interactive
whiteboard
Select Grouping and changing materials from the Science Clips website. Explain
they are going to sort objects according to the materials they are made from.
Read through all the categories. Ask the class to suggest an item that would be
appropriate for each category. Select the first item from the conveyer belt.
Which category should it go in? Ask children to justify their reasons. Work
through the rest of the items in this way asking a different child each time to
select and justify their choice. When all the selections have been made, check
them. Are they all in the correct category? Are there any that anyone would
like to change and if so why?
Group work using a computer
for each group
Select and explain the activity as above. Work together to select the first
item and place in the correct category. When the children know what to do,
allow them to complete the rest of the experiment at their own speed. As the
children are working observe and question them about their choices.
Plenary
Ask the children to think of some other objects that could be added to the
items in the activity. Which is easier to find things for? Why do you think
this might be?

Extension
Use reference books or CD-ROMs to find out how some materials, e.g. glass,
paper, earthenware are made from naturally occurring materials.

Suggested homework
Ask the children to find some man-made or natural materials at home, in the
garden or park, and to create a collage using these materials. Ask them to
bring their collage into school, and compare the variety of materials
found.
