Today was spent at home. I know, shocking isn't it? First day this week where we were at home and well enough to actually do some work proper. Well, I say proper, but basically it was having lots of fun.
We started slowly again. Both myself and Callum aren't really 100% this week and mornings seem to be very slow. Then it was a quick discuss of what we wanted to do and and overview of what he already knew about colour and light. Then work began in earnest by....eating chocolate! Yes, I did say eating chocolate. I know we could have just unwrapped them to get to the coloured cellophane, but where's the fun in that and it was 11am by this point, so accompanying a cup of tea it counted as elevensies.
After our small choc fest we gathered up the wrappers and brought together our stock of 6, yes 6, torches (2 wind up and 4 battery) only to discover that the 2 large battery ones had no batteries, 1 of the small battery operated one's bulb had gone and the 2 wind up ones weren't holding their charge very well. This left us will 1 battery operated torch that we could realistically use for our colour and light experiment.
We did 2 experiments in all using the cellophane and torch. One to show primary and secondary colours and one to show how different colours put together make white light.
Surprisingly the above 'white' light is made from putting blue, red and green cellophane together over the torchlight.
Just to prove that it wasn't a fluke, this one was red and yellow cellophane making a definite orange colour.
Next we put 4 strips of kitchen towel and dotted with different coloured felt tipped pens and immersed the ends into a small amount of water. The idea was that the water would bleed up through the dots and carry the ink upwards. Some colours would, hopefully, show up as the different colours that they were made from. However, we did red, blue, yellow (primary, so should have remained the same) and a green (which should have shown up as yellow and blue) and none of them separated. Might have to try another colour or different types of pen.
After finishing up and printing off some results for our science book we had a late lunch in the garden as it was so lovely outside and then potted up our experimental garlic. We are using cloves of garlic that have sprouted green shoots that we use for cooking and seeing if they will develop into proper bulbs.
Then maths and literacy and the 'school' day was done.
We've had a great time today basically playing about and having a laugh, but then I think that's how education should work. We're going to take the whole colour/light thing a bit further next time and try to look at rainbows. I also want to use it as a starting block for looking at art using blocks of colour.
Anyway, that's today done, cya tomorrow.
