On 12th March 2018, Dr Francis launched science week at Toftwood Junior school! We were ready for a jam packed fun week of science!
We began our year 3 science topic ‘Rocks and Fossils’ this week and have looked at the three different types of rock, igneous, sedimentary and metamorphic. We also discussed natural and man-made rocks and in groups decided what category the rocks went in! We then looked at some rock samples and using a key, worked out what they were! We had a lovely time doing this even if gneiss and granite looked really similar. To finish our week off we started looking at fossils! We learnt about the difference between bones and fossils and that there are 3 different types of fossils (trace, body and chemical fossils), what there are and how they are made! We then learnt about and ordered the way in which a body fossil is made!
On Wednesday we had some visitors from Neatherd High School to complete an experiment with us. We learnt about chromatography and looked at how to separate colours in ink. We used different felt tip pens to see which colour had the most colours inside it! We first put a dot of our chosen felt tip pen on chromatography paper, we then dipped the paper in some water, making sure not to dip the ink in! We watched as the water travelled up the paper and separated out all the colours! We enjoyed comparing our results and discussing them with each other – we were amazed at the pinks, yellows and blues which came out of the black ink!
On Friday we had another visitor come in to teach us all about oral health. We learnt about how much hidden sugar was in drinks (13 teaspoons of sugar in a ‘healthy’ strawberry yoghurt drink!). We also found out how bacteria can build up in our mouths between brushing and how to look after our teeth – we were all left desperate to clean our teeth after the session!
