I wasn't blogging when we did this - so I will repeat this activity to take pictures and show you our results.
Some colours did not mix when we shone the light through the bottles. I was told by 'Science Bob' that the rounded bottles threw my experiment off. He said I should have tried putting the colours into ziplock bags and hold them up to a window for better results. He also said to experiment with how much coloring to use for the best effect.
OK this weeks activity! :) This will give me a good reason to use my new light table!
The blue and yellow to make green worked great - so did red and yellow to make orange - but not as well - the blue and red to make purple did not work at all.

Update to follow! :)
How interesting to know that you should use baggies instead of bottles!
ReplyDeleteLove your little poster! I have had the same problem with the red and purple when mixing different coloured playdoh. Have to really get the ratio's right! Quite trick! :)
ReplyDeleteWell let's see if the baggies work! :)
ReplyDeleteI wish I knew where I got the poster - I have been storing so many things on my computer for a long time - most stuff I have no link to! Sadly!
