A suite of interactive features on the different concepts
of light showing:
- torch lights being added (to demonstrate colour
names, appearances and addition of colours)
- viewing a scene through red, blue or green coloured
filters
- viewing a fruit bowl display in different coloured
lights (to demonstrate the appearance of different
coloured objects in different coloured lights).
These could be used by teachers as plenary or revision
activities to reinforce the different ideas associated
with light. All the features can be accessed from one
entry screen where five options to choose from will
be presented. They could be used with an interactive
white board, digital projector or with groups around
an individual computer. It is recommended that some
practical light experiments are tried in class before
using this. The concepts of colour addition, subtraction
and reflection can be easily confused, so a teacher
may choose to focus on just one feature at a time. The
materials can be discussed verbally, or a teacher could
create result recording sheets to use with these activities.
If used by students independently, the torch lights
feature would work particularly well to reinforce the
names of colours (since it also incorporates speech)
whilst developing the students' fine motor skills through
controlling the mouse.
The filters examples demonstrate that only certain
colours can pass through a filter. For example, when
looking through a blue filter at a red object it will
appear very dark and possibly black. This is because
red light cannot pass through a blue filter. You can
try this with real filters but it is hard to get pure
colours so the results are not always perfectly clear;
therefore the interactive demonstration will clarify
the key learning objectives.
The fruit bowl deals with the principle of the reflection
of light from objects and why they appear to have a
particular colour.
The torch lights feature was donated by Simon Evans
who has his own SEN Teacher Resources website at http://www.senteacher.org/
The other features were donated by Sandy Wilkinson from
