Today the pupils investigated the pattern between shadow size and the distance of their light from the object. They plotted x-y scatter graphs that showed this relationship, and had great fun!
Chromatography works like this: when some ink gets wet, the ink colours get wet and flow to the top. The heaviest colours are dropped off first then the ink’s lighter colours get dropped off until there are no colours left.
In science we have been learning about Forces. This week we were dropping paper cake cases from a certain height, and adding one on each time. My group dropped them from 1.4m and timed them to see how long they took to get to the ground. We found out that our prediction was entirely correct (that when you add a cake case, it will fall quicker because there will be the same amount of air resistance but the mass has increased) but we also found out that the speed is increasing but it can kind of only reach a certain speed.
