Introduction to Physics
Our opening science experiment and investigation involved observing and predicting the motion of a variety of different objects on a sloping surface. We began during Open Play time in the sandpit. In the first week, we used a variety of slopes and the blue metal stands to create varying degrees of slope. We observed how the balls and cars were able to slide down the half pipes and commented on what happened when we moved the position of the pipe from the top rung, to those below it. As we got used to the process, we started removing the blue frames and replaced them with a variety of alternative objects. Our task was now to build different ramps and predict what would happen to the cars and balls. We started connecting half pipes together to form longer ones, leaning them on the windowsill or mirror to make them even steeper, and working together as a team, vocalising our plans as we went.
During one of our circle times, we started experimenting with a variety of objects. Starting with a ball, we moved onto different types of cars, blocks, a soft toy giraffe, a solid dinosaur, full water bottle, and an empty water bottle. Each time a new item was presented, we had to make predictions on what we thought the object might do. Would it roll? Slide? Stay still? Would it go all the way under the cubbies, or only make it to the bottom of the slope? Would it go straight? Or would it bend to the side? We would start our sentence by saying 'my prediction is...' After making a variety of predictions, we then carried out the experiment, observing and then concluding the result each time.
Pendulum Power
Another investigation into motion involved a variety of pendulum experiments. We started off small, over the sensory tray. Tied to a pole above our heads, was a dangling cup. Multiple holes had been made in the bottom, to allow for the paint to drip out. We started off with one colour: yellow. Watching closely, we noted what happened to the paint when we moved the cup in a number of different ways. We watched as the paint dripped out in a big circle when we spun the cup all the way around the tray, that it followed the line of movement when we swung it straight across the tray, and how much more came out when we shook the cup up and down. Soon we were adding more and more colours to our cup, and watching as the different colours landed on and next to each other, sometimes forming to create a brand new colour.
Our next phase of the investigation meant levelling up our pendulum! This time we cleared a large space on the floor, and rolled out a long piece of paper under our feet. Two gloves were hung, with the string being tied well above our heads. We poured one colour into one glove, and a different colour into the second glove. Holes were cut in the fingers, just as they had been in the bottom of the cup. A cardboard wall was built around us so that we could contain the splash zone. After taking off our socks and shoes, donning an apron, and rolling up our trousers, we were hoisted over the wall and into the experiment zone with the help of our teachers. Each day we added two new colours to the gloves, laughing and chatting as we swung the gloves across the paper and to each other.
For our final phase, we converted our pendulum into a construction tool. The gloves were replaced with a heavy ball, fenced off behind some signs and cones. As a team, we built up a variety of structures using the foam bricks. We then made a prediction as to what would happen when we swung the ball back and into the tower. Once we had cleared the space of all the builders, we took turns trying to knock the towers down using different techniques and swinging styles.
