Today Year 4 started their new unit of work in RE 'The importance of sharing food for Sikhs and Christians.' To introduce this topic, the children discussed different religious celebrations where food is shared as a common theme. The children then thought of a personal experience where they have shared food with others and how this made them feel.
This week in Maths, we introduced the formal written subtraction method with decimals. On Monday, we had a go at grouping subtraction calculations into those that need regrouping and those which don't. In the next lesson, we used the formal written method to complete the calculations, using a coloured pencil to make the regroupings clear.
'When I hit the xylophone with the beater, the shortest bar produced the highest pitch sound because the sound had less distance to travel so the wavelength was shorter.'
'With the ukulele, when it had a tight string it had a higher pitch because the vibrations were able to travel faster.'
In PSHE this half term we are focusing on 'Dreams and Goals.' Today we analysed a song titled 'For Me' and had a go at writing our own verse and chorus to include our own dreams and goals.
In Maths, we have been focusing on decimals and how we can compare, order and estimate. We reminded ourselves of what it means to 'estimate' using terms such as approximately, guess and predict. Next, we used number lines to find the mid-point, lower and upper quartile, which aided us in estimating points on given number lines.
As part of our Science unit of work on sound, we made ear gongs and string telephones. The children were able to see how sounds are made from vibrations, which travelled down the string in both experiments.
'My favourite sound I made with my ear gong was when I bashed my coat hanger on the white board, the volume was the loudest and the pitch was the highest that I tried!' (Abel).
'When I held the string in the middle of the cups,it stopped the sound because it stopped the vibrations.' (Hermione).
In English, we have been doing a whole-school engagement unit based around the book 'Tuesday' by David Wiesner. We have been focusing on using conjunctions to link our ideas within a sentence. Today we went in role as David Toadborough, an animal expert reporting on the behaviours of the Human species. This role allowed us to reflect on how the toad's felt in the book, using formal tone to reflect our profession as reporters.
Last week in Maths, we focused on interpreting discrete and continuous data to make our own conclusions. Today, we moved our learning on further to making, collecting and recording our own data. We counted how many hops we could do in 2.5 minutes in 30 second intervals and the number of time each dice number was rolled in 2 minutes. Next, we categorised each data set as continuous or discrete data and chose to present the discrete data using our own bar charts.
'The water cycle is when water travels from land to sky and back again. The water cycle starts when the sun heats up water in rivers and seas so that the water evaporates into the air, as water vapour. The next stage of the journey is known condensation which is when the water vapour particles combine with others to form a cloud. When this cloud gets heavy, it releases as rain, sleet, snow or hail. This is known as precipitation. The last stage is called run off when the rain runs down surface likes hills and mountains and collects in seas, rivers and puddles. Did you know that the same water we have today is the same water that the dinosaurs drank?'
In English, we have been looking at identifying head nouns in order to help us to build our own expanded noun phrases. We used our book 'The Boy at the Back of the Class' by Onjali Q. Rauf as a theme for our sentences, which linked to Anti-Bullying week.
Today in RE we made our own Advent wreaths in table groups, focusing on the four main themes of Advent: peace, love, joy and hope. We discussed how we can create joy, what we wish peace upon, what we have hope for and what the world would look like if it was only full of love.
This week in RE, Year 4 have explored the place of worship for Hindus, the Mandir.
'When Hindus enter the Mandir, they take their shoes off and wash their hands as a sign of respect' - Billy.
'In the Mandir, they have lots of statues of Gods and Godesses' - Eliza.
'Mandirs are often very colourful, with different colours to represent different Hindu deities' - Sophia.
This week in Science, Year 4 replicated how food is broken down in the human digestive system, using tights and a variety of foods. We found it very tricky to break down the food with our hands before water was added, imitating the job of the digestive acid.
This week in RE, Year 4 discussed where they like to go when they want some quiet and calm time, this included: their bedroom, their garden, their rabbit run and their play-house.
We then related this to the Hindu shrine and the Puja tray, which is used when praying to their chosen deity.
In Science, we carefully observed the results of our egg experiment, emulating the impact different liquids have on our teeth.
We found that the coca-cola damaged the shell of the egg the most, that the vinegar preserved the inside of the egg and that the water did not damage the shell of the egg at all.
We used our results to write letter as Dentists, giving our top tips for healthy teeth!
We set up a fair test experiment where we set out to find out which liquid (milk, vinegar, coca-cola or water) causes the most damage to hard boiled eggs, emulating the effect it has on our teeth.
'The least amount of damage will be from the milk. I think this because it is good for your bones.'
'My prediction is that the coca-cola will break down the egg the most as it has a lot of sugar.'
Next week, we will be looking at our results and making a scientific conclusion.
In Tuesday's maths, we learnt how to regroup 4-digit numbers. We used place value notation to help us to show the regrouping and understand how a number can be written in several different ways.
We then challenged our understanding by completing a number riddle.
In PSHE this week, we focused on how we can make our Year 4 class a team. We discussed the words 'included' versus 'excluded' and thought of situations where exclusion and inclusion have occurred. As being inclusive is one of our school values, we then discussed how we can be move inclusive.
'People would feel included if everyone was kind.'
'Including means listening to others people's ideas, letting them know they are appreciated.'
