In our science lesson, we observed the effect of evaporation on water. We created puddles of water in the shade and in the sun and observed what happened to them by measuring them. The ones in the sun got significantly smaller during the half hour. This was because the sun sped up the process of evaporation. Those in the shade mostly stayed the same, although when we checked at the end of the day, they had also evaporated.
Our Topic for this half term is ... WATER!
We will be learning about rivers and the Water Cycle.
Here are the results of our science 'eggs'periment. We found the acidic liquids like lemon juice and vinegar had the most damaging effect, dissolving the egg's shell. Milk and water had little to no effect on the shell. Energy drink left an unpleasant looking, bumpy white coating on the shell. Both orange squash and cola changed the colour of the egg shell. In conclusion, we decided it is important to brush our teeth often to avoid any liquids damaging our enamel!
We are celebrating Science Week this week by conducting an experiment to test which liquids will rot away enamel (eggshell) the fastest. As a class we discussed how we would keep the test fair and decided to use the same size eggs, the same amount of liquid and keep them in the same place so they are the same temperature. In our groups we chose 3 or 4 liquids to test including energy drink, cola, milk, vinegar and lemon juice. We made predictions about which liquids would rot away the eggshell and which would not. We will be observing the effects and discussing the results in a few days!
Year 4 Europe Song
During our music lesson, we decided to write some lyrics to a song we were learning to play on the glockenspiel. We had to think about European countries with the right amount of syllables to fit with the rhythm.
Today we have celebrated World Book Day with lots of different reading activities. We brought in our favourite book and talked to the rest of the class about it. Afterwards, we went to Year 1 and shared our favourite stories with them.
We have begun reading 'Gulliver's Travels' and today we worked in groups to act out the main parts of the story so far using puppets that we created based on character descriptions.
Our topic this half term is called 'Passport to Europe!'
In our English lessons we have been working on persuasive adverts. After watching the Sprout Boy video where 'nobody likes a sprout', we decided to create persuasive adverts to highlight all the positive aspects of sprouts and persuade people to buy and eat them, even after Christmas!
Please enjoy some of our persuasive adverts in the videos below:
Thank you Year 4 for all of your excellent homework! Here are pictures of some of the wonderful and creative things you have made to represent the digestive system! There were also many fantastic diagrams in your learning logs and some wonderful powerpoints.
Today we were lucky enough to be visited by Maira, who is a Dental Nurse from Clayton Brook Dental Surgery. She talked to us about how we should brush our teeth and why we should brush our teeth. After this, she gave us some special tablets and when we chewed them, they made any plaque on our teeth turn pink! Then we brushed our teeth and brushed away the pink covered plaque. After this, we designed some posters with 5 top tips for total teeth health!
In science today, we have been learning all about how our bodies digest food. To model the process that goes on inside our bodies, we mixed some water (saliva) and some orange juice (stomach acid) in a bag along with a cracker. We observed that the cracker went from being solid to being a 'mushy' liquid. We then used a pair of tights to demonstrate how the intestines take the useful nutrients and absorb the water back into the body leaving you needing the toilet!
This half term our table groups are named after famous composers. In our groups, we researched our composers and put together a powerpoint presentation to tell the rest of the class all about them. We found out many interesting facts such as Schubert and Mozart are both from Austria and Debussy died of cancer 100 years ago. We also listened to some of their most famous pieces and recognised Beethoven's 'Fur Elise' and Tchaikovsky's 'Swan Lake'.
This week, we have designed and created a spectacular model Christmas village. First we evaluated current Christmas village models and decided we wanted ours to be colourful, varied and neat. We then each designed an individual building and an 'extra' part of the village e.g. a swing for the playground. We collected the materials we needed and set to work making our buildings from card, paper mache and paint. As we have learnt all about electrical circuits, we used some LED Christmas lights, powered by batteries, to light up the inside of our buildings. We finished our village with a sprinkling of Christmas snow.
Year Four's extraordinairy Christmas Village
Our topic this half term is BRIGHT SPARKS and in science, we are learning all about electricity! We have been making circuits with bulbs, buzzers and motors and we have researched electricity using some interesting books.
We investigated which liquids were the slowest. Surprisingly, golden syrup wasn't always the slowest liquid! We found soup and washing up liquid to be the fastest.
We discussed different solids and worked out what materials they were made from. We thought about whether these materials were synthetic (people-made) or natural which led us to an interesting discussion as to whether bones and skin are 'people made' or natural. We then compared and classified some materials based on their properties.
To kick off our Science week, we planned and carried out an investigation into whether listening to music helps our memory. Our results found that 14 people's memory scores improved when listening to music, 6 stayed the same and 5 got worse. We concluded that some people may learn differently to others.
We also worked in small groups to research some famous scientists. We discovered some really interesting facts such as:
* Thomas Edison invented the lightbulb
* Stephen Hawking's machine speaks in an American voice but he is British
* Marie Curie has a cancer charity named after her
* Albert Einstein hated school but taught himself at home
* Charles Darwin was a naturalist, geologist and a biologist!
* Sir Isaac Newton discovered gravity

We have been reading T S Eliot's 'Macavity: The Mystery Cat', and today we have been working in groups to perform the poem. Watch the videos below to see the full poem.

Our 'Plague Cure' adverts
Today, we learnt about different ways that people tried to cure the Plague in the 1600s. From leeches to drinking urine, they were sometimes a little gruesome! We created and performed some adverts to persuade our audience to choose our cure.
