In Science, we have been learning about forces and in this particular lesson, we have conducted an experiment testing the force of gravity on a variety of objects. We have already learned that gravity is a force that pulls everything to the centre of the Earth but is the force the same for everything? Today, we used force meters to measure the force on a variety of objects by placing the object in a plastic wallet and hanging the wallet from the force meter, which measures the amount of force on the object. Objects chosen include stationary, stones, plant pots etc. We made sure this was a fair test by using the same force meter each time, the same plastic wallet and the object was held by the same person from the same height. The one variable we changed was the object.
We achieved many interesting differences in readings of the force meters and asked ourselves: what affects the force on each object? Why are the readings so different? We speculated on possible reasons and decided to weigh each object to see if there was any correlation between the weight of the object and the force meter reading. We discovered that the heavier items had more gravitational force than the lighter objects.
Learning about this in science was a lot of fun and I learnt a lot about scales and gravity
