Light and Colour

The term has not quite fizzled out completely but aware if I don’t start recording our project work I am going to look back and think that it did.

Science was a fairly ‘light’ topic – ha!  What I mean is that we weren’t dealing with anything particularly new or difficult.  More a hands on playing, reinforcing ideas time.

We continue to use the book The Way Science Works as our base.  Reading the content and doing as many of the experiments as possible.  We’re joined by friends for some of the experiments which helps keep it fun.

Not as many photos as I’d like.  Exploring light involves using hands to hold torches and prisms etc and it’s hard to photograph torch beams in the dark.

We started off looking at reflection and refraction by playing with convex and concave lenses.

20141217_4We explored shadows with puppets.


Then we moved on to looking at how eyes and cameras work.

We explored optical illusions with the tube to the eye, making a hole in the hand trick.   With plenty of time playing on here later.  Looked at how microscopes work.

20141125_26We had another go with this Camera Obscura kit to more impressive results.

20141212_820141212_10We finished with a look at colour.  We split light with a prism and did some chromatography.

Talking about colours, rainbows and the light spectrum led to making a waldorf star.
