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

Lesson 3
Energy and Forces
NOW YOU SEE IT! NOW YOU HEAR IT!
Teacher Notes
Science Inquiry Focus:
How does light help us see? Does light help us see
colours?
Skills Development/Working Scientifically:
• Questioning and predicting
• Observing
• Investigating and experimenting
• Analysing
• Recording and communicating
Science Learning Outcomes:
• Pupils act like scientists when they observe, ask
questions and describe different colours and how
they can be seen.
• People use science in their everyday lives such as
when comparing how light sources can be used.
Background Information
• Colour is reflected light. We see colour in one of
two ways: an object can emit light waves in the
frequency of the colour we see; OR the object will
absorb the frequencies of all other colours and
reflect back only the light wave, or combination of
light waves, that produce the colour we see. The
colour of an object depends on the colour of the
light source.
• At this age level, it is sufficient to simply observe
that white light is made up of all the colours and
lets us see objects and their colour. Changing the
colour of light will change the colour we see. This
video also offers more Background Information
.
• The rainbow spinner activity: White light is
composed of all colours of the visible spectrum.
Spinning the circle mixes all the different
wavelengths of coloured light together, creating
white light. The faster the circle moves, the more
white light is visible.
Technology/Engineering/Mathematics
Links:
• Recording results by taking a
photograph with a digital device.
• Using informal measurement to cut/
select appropriately sized pieces of
cellophane.
• Working in a team and following
a sequence of steps to construct a
shoebox viewer.
Assessment Focus:
• Teachers may choose to speak
individually to selected pupils about
how colours are formed while they are
completing their shoebox experiment.
• Teachers may ask pupils to write one
or two sentences (or draw pictures)
to explain that light is made up of
different colours and it helps us see.
