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.
The pupils planned presentations about different animals, including finding out about how they reproduce. Their presentations were fantastic!
In science we have been looking at rockets and planes. The photos below show the hoop planes that the pupils built. Some of them flew all the way across the room!
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.
Here are our results from the experiment
Levi has made this post! Gears change the speed and the power of things. Today we all had a go on the bicycle on the turbo trainer. We worked out our average speeds, and felt what it was like in different gears.
Pupils were given the chance to dissect pigs’ eyeballs from the butcher. We were all fascinated by the lenses inside the eyes. When you put the lenses on some newspaper they magnified the writing.
The pupils realised that you can make a really stable toy by making sure that the centre of mass is below the point (the pivot). Robbie showed that maybe tightrope walking is not as hard as it looks – just get a long bendy pole!
The pupils all managed to do the fork balancing trick! It looks impossible, but because the centre of mass of the two forks is somewhere between the two handles, it is possible to balance them using a cocktail stick and a glass (or measuring cylinder!)
The pupils have been stretching springs and plotting some fabulous scatter graphs.
Here is our final result graph:
Hey guys me and Josh were working together on the experiment. Here is a pic of Josh’s results for everyone to look at. How did it go with you?
