 What have we been learning in Science this year...?

June 2019 - Year 5 - Moon Phases

As part of their topic of Space, Year 5 have been learning about the phases of the moon. They did this by using the incredibly creative (and yummy) idea of biting  Oreos to show the progression and phases of the moon through the lunar cycle. They learnt the difference between waxing, waning, full moon, half moon and quarter. I think it's safe to safe a great time was had by all!

25.6.19 - The lights are on in Year 4!

 As part of our Year 4 science topic of electricity, we got stuck into understanding how circuits can be complete and incomplete. We tested a variety of circuit set ups using wires, batteries and light bulbs. We noted when circuits worked and when they didn't, we then examined our results to find out why circuits did or didn't work. It was great fun and we enjoyed using the vast selection of electricity resources

Summer - We're feeling electric in Year 4!

Year 4's final science topic for the year is Electricity! We've been getting a buzz on about the subject and are keen to share some of our new found knowledge. Most recently, we've been looking at the production of electricity. We now understand that it is a secondary source of energy, this means that it is produced by another energy source. Check out some of our informative videos for more information!

St Andrew's are getting green!

To kick start the last part of the Summer term, St Andrew's have been identifying and naming different trees. They have learnt that evergreen trees keep their green leaves all year round. They also know that the leaves on deciduous trees change colour in Autumn and fall from the tree. 

Our budding little scientists went on a tree hunt in our environment to see what they could find. They found a holly bush which they know is evergreen because they can see holly at Christmas! They found lots of deciduous trees such as Ash, Birch and Elder. They collected some of the leaves to make a collage of the deciduous and evergreen trees that they found!    

Year 5's Lichen Hunt

We had another visit from Sustrans today, who taught us all about what lichen reveals about pollution! The children did an amazing job identifying the different kinds of lichen all across our school. Beware - they are armed with tools to disarm air pollution!


Year 5 Exploring Life Cycles

This week, we visited our school pond in search of frog spawn. We found some, collected it and brought it back to our classroom for observation. We even found a newt!


Upon returning to the classroom, we learned about the life cycle of an amphibian. This then extended to learning about the life cycle of a plant! In order to find out how it reproduces, we cut up some flowers and looked inside to label each part of the flower. We will be dreaming of the carpel, stamen and styles!


Summer 1 - Year 4 -We've Got Ourselves into a State....OF MATTER!!!

This half term in year 4, we've been working on our physics skills. We've learnt that everything is made up of Matter and that the 3 types of Matter are solids, liquids and gases. We also know that Matter is made up of very tiny pieces (particles) known as atoms. Most recently, we've been investigating gases. We know that liquids and solids have a weight that we can measure, we wondered if gases had the same. So, with a little help from Joseph Priestly (a very curious man who lived a long time ago), we conducted an experiment to see if carbon dioxide had a weight.

Carbon dioxide can be found in fizzy drinks (thanks Joseph Priestly). So, we first measured out the same millilitres of fizzy drinks into cups, we then weighed the cups mass. We left the drinks for 24 hours to go flat (that means let all the carbon dioxide escape). After 24 hours we re-weighed them. The change was amazing! Some cups had lost almost 20g of weight, just by letting the carbon dioxide out!

Year 5 Exploring Forces

 To wrap up our unit on forces, we threaded straws onto string, taping balloons to the straw and watching them fly along the route! See our setup and results below.


March 2019 -Year 4 - The Tooth Decay Experiment Part II

As you can see below, Year 4 were carrying out an experiment about how fizzy, sugary drinks can affect out teeth. We left our eggs for a week and have monitored them every day. On Thursday, 22nd of March, we removed them and examined them for changes. All eggs had suffered severe staining and mottling of the surface, several had cracked and some had even begun to leak! We established the sugary drink had ERODED the surface of the egg, like it would our enamel, then broken through to the more sensitive layers. Where there had been toothpaste of the egg the damage was lessened but even the toothpaste had been partially washed away by the sugary drink. Year 4 came to the conclusion that sugary drinks should only be had as a treat and that brushing your teeth regularly was important for maintaining good dental protection

Spring term: Year 4 Get hot on the topic of tooth decay!

As part of learning about the digestive system, year 4 have been learning extensively about teeth: the types of teeth, what teeth are made of and how we protect them. Year 4 are carrying out an investigation into how toothpaste can help protect are teeth from damage.  Year 4 discussed how in the future the experiment could be done with different drinks to see how they impact our teeth. Then they could create a scale to advise other children which drinks are better for their teeth. 

Spring : Year 5 Were Using The Force!

As part of their exploration of different forces, Year 5 have been testing out water resistance by comparing how quickly an object falls through water compared to air. They made observations of the experiment and then had a discussion about what they noticed. They then applied this knowledge to a posed question: who would face more water resistance, a shark or a minnow?

Spring : Year 6 Became Introspective 

Year 6 have been learning to identify the key organs of the human body and looking at the functions they perform for us. Year 6 were creative and made whole body maps to help children plot organs accurately but also assist them in understanding the proportional size of human organs.

Autumn: St Margaret's have been learning all about SOUND!

Year 4 have been learning all about sound this term and wanted to make a video to share their knowledge with others! So here are our two wonderful presenters ready to teach you all about how sound travels!

Autumn :They Were Blasting Off In St Elizabeth's Class!

St Elizabeth's Class have been making a great use of role play to inspire the children in their science topic, Space! Children enjoyed acting as astronauts with even astronaut packs being made at home to share with the class. They learnt about Neil Armstrong and re-enacted his moon landing! 

Autumn: Lights On In Year 3

Year 3 were investigating the truths and falsehoods about light by organising statements and taking place in group discussions where they learned to apply their topics key words. They also used torches and a variety of materials to investigate how materials are affected by light and how shadows are created. 


In St. Philip Howard, we have been exploring different ways to separate materials. In doing so, we learned about Victorian sewers where everything would end up the Thames! How did they separate it, we wondered, and set off exploring. Below are some of our approaches.


Autumn : St. Philip Howard

This week, we have been checking materials for their properties. This includes investigating whether a material is soluble. Above, you can see Year 5 experimenting, mixing water and items such as hot chocolate, tea, cinnamon, cardamom, salt, pepper and others.

Autumn: St Philip Howard

This half term, we have been looking at the properties of materials. Here are some year 5's ordering a variety of materials according to their properties, using words such as: soft, hard, dull, bright, transparent, opaque, brittle, flexible, soluble and many more!

Autumn :St Teresa

Year 6 have been up to all things scientific this year! As part of their learning "Inheritance and Evolution" they looked at fossils and learnt about famous paleontologists like Mary Anning and Charles Darwin.


As part of their next topic, "Living Things and their Habitats" they learnt about how living things are classified into different kingdoms. The children worked in groups to research their "kingdom" using factual books and the internet and then recorded their findings for part of our class science display.


As part of their third topic, "Animals including humans," Year 6 pupils learnt about the circulatory system. They were taught about the different components of blood and the functions of each of the different components when they made their own, "blood."
