We had great fun investigating electricity and how electrical circuits are formed!
We used insulators and conductors to make working torches and fans. We investigated how conductors can attach positive and negatively charged wires together to create and electrical circuit! The conductors attached wires together and sent electricity to different areas on the circuit. The wires were protected by plastic insulators.
It was so exciting to watch the light-bulbs light up and the fans begin turning when the circuit was complete!
OUR NEWSPAPER BRIDGE
In December 2016 we did a science project to test the strength of paper. We had to make a bridge of newspaper and see how many copies it would support. We separated the tables, leaving a gap wider than a copy. Then we placed a sheet of newspaper across the gap, to keep the paper in place we put baskets on each end for support. Then we started putting the copies on but we got around 50. Then we thought about folding the newspaper in half and putting on tape instead of baskets. It made it stronger and we got 77.

We learned about different kinds of materials and their properties. We carried out an experiment to test some materials. We tested a tennis ball, a sponge ball, a ball made from plasticine and a ball made from rubber to see which one would bounce the highest. We wrote out the experiment and carried it out three times to make sure that it was a fair test. We discovered that the tennis ball was the bounciest ball.
We did some more experiments today. Click on the link to watch the video.
Stand with your back and heels against a wall. Drop a coin on the floor in front of you. Can you pick it up without falling over?
Stand with your feet apart, one foot, shoulder and head all touching the wall, and raise your other leg. Dead easy- or is it?
We’ve been enjoying science week this week. We’ve done lots of experiments.
We put an egg into vinegar and we’ve been watching what happens. The vinegar erodes the egg shell.
We put ‘Mentos’ sweets into Coke to see what happens – it exploded!
We put raisins into Seven Up to see what would happen. The gas in the Seven Up makes the raisins rise and fall.
We put warm water on ‘Skittles’ sweets to create a rainbow.
We recorded all our experiments in our copies.
We loved doing our experiments because we could eat and drink most of them when we were finished! Click here to see our video.
