Today we investigated levers.  We learnt that levers can be used to lift larger, heavier loads using a much smaller force.  Here we are investigating the significance of the pivot point.  We made the heavier objects rise on our ‘ruler balances’ proving that a small force can indeed lift a larger…

This week we are looking at the concept of water resistance.  Here we are investigating whether or not more streamlined shapes drop through the water more quickly.

We have been investigating which solids dissolve in water. We found out that sugar, salt and coffee do dissolve, they are soluble. Sand and rice do not dissolve, they are insoluble. We then filtered our mixtures to see if we could get the particles back but we could only retrieve the sand and…

Today we were investigating the best place to dry our washing. Each group chose a different type of cloth and decided how much water to put on each one. We had to put the same amount on each one to make sure the test was fair. We weighed the cloths and then chose different locations around the…

Today in Year 5 we dissected flowers to find all the main reproductive parts. We knew the names of the parts but bringing the outside in helped us to learn where each part was and its function in pollination and fertilisation. We had remembered a lot from our lessons in Year 3 where Mrs Dowson…

We have been exploring the mixture of cornflour and water. It is known as a non-Newtonian fluid as it doesn’t follow the rules for either a solid or a liquid. We squeezed it, turning it into a solid and them let it go to see it turn back into a liquid. It was really fun, interesting and…

Today we have been learning about Joseph Priestley, the man who invented fizzy drinks. He worked out that if he put a gas called carbon dioxide into drinks it made them fizzy. We have been investigating whether gas weighs anything by shaking bottle and letting the carbon dioxide escape. We found…

We made raisins dance today by putting them into a glass of lemonade. The bubbles (carbon dioxide) made the raisins dance. We talked about how this happens.

We really enjoyed discussing which foods we should eat and shouldn’t eat as part of our ‘Brilliant Bodies, Brilliant Brains’ topic. We used our sense of ‘taste’ to try the delicious fruits and vegetables that the children brought in. We even had some avocados fresh from Nigeria ! 
We enjoyed…

We have been discussing different ways of separating mixtures such as hand separation, sieving or sifting and using magnets (which was a recap on our knowledge from Y3). We had a variety of different mixtures that we had to separate using sieves that had lots of different sized holes. We had to…

The children enjoyed predicting what they could smell. It was interesting that some children thought it was chips when it was tomato sauce! 

We explored the school grounds to find out what happens in autumn. We went to the horse chestnut tree and spotted all the colours that the leaves are turning. We also picked up something that we could draw back in class.
