Science Week - 2018
Exploration and Discovery
In our Science week assembly we looked at how balloons can help us learn about Science. Caleb offered his knowledge about magnetic forces to describe how the electrons move in static electricity. Jonah described his understanding of gravity clearly as a force that pulls things to the earth. Everyone and all the volunteers in the experiments participated with enthusiasm and interest.
Following on from their maths work on measures, KS1 started to ask questions about parts of their body ...... "Is our armspan the same length as our height?" "Which parts of our bodies are the same length?" "Do children of different heights have different sized feet?" So many questions!
KS1 decided we wanted to find out if any of our questions could be answered. We made a grid and measured some children's body parts to see if any of our thoughts were true. We measured accurately and filled in a chart carefully to record our results. There were some surprising results. Look at our displays on the school stairs and in our classroom to see the results.
Animal faeces – year 3 and 4 had great fun creating different kinds of animal poo. We had to find out the types of food they would have in their poo and copy the size, shape and colour of the poo. Later we had to identify the different types of poo to the identification sheet.
In year 6 we carried out an experiment to do with taste:
Did you know your tongue is covered with about 10,000 taste buds? These detect five different tastes: salty, bitter, sweet, sour and umami. Umami, discovered by the Japanese, means “savoury” and is a characteristic flavour of soy sauce. How do you think these different types of taste receptors are spread around your tongue? We attempted to find out.
Flight – After the visit last Friday by the birds of prey, year 3 decided to investigate flight. We made aerofoils in class to find out about the updraft and pressure changes involved in flight. Then we watched some information about birds by David Attenborough. After that we made our own aeroplanes and flew them outside, using stopwatches to time the amount of seconds they were able to stay in the air. “If I throw mine up in the air, it flies for longer and better!” claimed Lucy. Back in class afterwards, we drew some line graphs to show the time in the air over three flights. Our results were affected by the position we stood in the yard and also the way the wind was blowing.
Year 5 took cuttings from a geranium plant and discussed asexual reproduction. We discovered that the new plant will be genetically identical to the parent plant.
KS1 wanted to know why it was so important to wash our hands regularly. We decided to rub fresh bread on places in our classroom to see where germs can appear. One of us rubbed our hands with one slice of bread because we hadn't washed our hands after playtime outside. One of us rubbed the door handle and one of us rubbed a pencil. We now have to wait until the bread goes mouldy. We can't wait to see which one holds the most germs. All of KS1 are going to wash their hands thoroughly and regularly now to stop germs getting into their bodies.
Yr 4 have been looking at habitats this term so we created a bug hotel to attract insects in the garden. We also looked at how to free objects frozen in ice.
Early years have been exploring bubbles this science week. First we discovered how to make bubble mixture and then we used different bubbles wands to see which made the biggest and best bubbles! Isaac said “The small ones worked best because the air moved slower”. We also used bubbles to create prints in art. We added dark coloured paints to see which worked best. Oliver discovered the bubbles were rainbow coloured because they reflected the light. Ida thought the glycerine in the mixture made them shiny. We then tried to fill the classroom with bubbles using the PTFA’s bubble machine. It didn’t fill the whole room because we couldn’t resist popping them!
What an inspiring week we all had!
