Capillary Effect

 

Kia ora, today while the year 7's were at tech us year 6's did science.

Last week on friday we made catapults for science and this week we did capillary effects.

First we got 6 cups and 3 different colours, the colours we started with were the primary colours (red, blue and yellow)

Then we filled 3 cups up with water then put the colours in.

We then folded some paper towels and put them in, we then watched the coloured water (molecules) climb up the paper towels and drip into the empty cups to create the secondary colours (Green, pruple and orange)
