This term, Year 2 and 3 have been looking at working scientifically. We have looked at some famous scientist and their discoveries and used this as inspiration for our own scientific experiments.
We looked at Isaac Newton and gravity and planned a simple investigation using spinners and paper clips. We made it a fair test by keeping everything the same and only changing one thing (the amount of paper clips on the spinner). The results of our experiment was that the heavier the object, the faster it fell to the ground. We concluded that the heavier the object, the more gravitational force it would have!
We then looked at how scientists study the brain and planned a simple experiment involving our reflexes using rulers. We had to drop the rulers and see how quickly we could catch them. We made it a fair test by keeping everything the same and only changing one thing (the hand we were catching with). Our results were that the hand with the faster reflexes varied. We concluded that our dominant hand (the one we use to write with) had faster reflexes because we used it more.
Due to the Corona virus, we discussed the importance of washing our hands properly and how easily germs can be spread if we do not practise good hygiene. We planned a simple investigation on what might happen to bread if we touched it with unwashed hands, washed hands and no hands. We made it a fair test by keeping everything the same and only changing one thing (what touched the bread). The results of the experiment showed us the mouldiest slice of bread was the piece we touched with unwashed hands.
We also investigated how easily germs were transferred using glitter glue and shaking hands. We then washed our hands with water and found that we could still see the glitter sticking to our hands. We then washed our hands using soap and managed to wash away the remaining glitter. We concluded that we should wash our hands properly to make sure that we did not spread germs!
