Today we were experimenting to see whether changing the shape of play dough affected the upthrust that acts upon it and therefore makes it lighter in water. We got some interesting results which we will write up on Monday.
Yesterday we altered our paper experiment to see if different shaped foil would make a difference to how many marbles could be held. We discovered that a bowl shape (like a buoy) or a rectangle/triangle shape (like the hull of a ship would be the best shapes.
In order to prepare for the arrival of King Henry VIII on March 22nd we have begun to practise a Tudor dance in order to impress him. We haven't done any videos yet but here we are getting some training in. Some of us even taught Mr Dale how to curtsy properly!
Yesterday we moved our Science topic away from gravity and air resistance onto buoyancy and upthrust. We began this area of the topic by investigating how many marbles we could keep afloat using different paper structures. We applied scientific logic by deciding that the marbles were better if kept in the middle of the paper. Most of us discovered that the larger the surface of the paper the longer the marbles (and the more marbles) stayed afloat.
Today we made huge Chinese dragons as part of our day looking at the Chinese New Year. We also made masks and wrote our names in Chinese letters.
As part of our forces topic we have been looking at gravity and air resistance. We have been designing parachutes that we think will have the most air resistance when it falls to the ground. We built them today and are going to drop them to see which design falls the slowest on Friday. Mr Dale is confident of victory!
