# Minecraft inspired Maths

In today’s Maths lessons, Year 4 children have been using bricks to explore the concept of the perimeter of compound rectilinear shapes.

They’ve discovered some of the pitfalls when calculating and have explored the relationships between the number of bricks and total perimeter.

# Tin Collection Competition

Thank you for supporting our tin collection competition on Friday 19th October 2018. We had a fantastic response and collected a huge amount of tins and there was some serious competition between classes!
The children had great fun carefully lining up their tins and the Year 6 children were experts, when it came to measuring each line accurately.
The winning class at Aire View site was Kingfishers and their line measured 10m 38cm!

The winning class at Hothfield site was Mars and their line measured 15m 57cm!

All the tins will be distributed to the Local Salvation Army Foodbank at Keighley to help people and families in need. Once again thank you very much for your support.

# Smile if you brush with fluoride

In Year 4 Science, the children have been conducting our final experiments on teeth and dental health.

Once again, we have used eggs as substitutes for teeth when testing.  This time we wanted to test whether fluoride toothpaste protected our teeth as well as cleaning them.

We rubbed half of an egg with toothpaste containing fluoride and left it for four days before rinsing it off.  Then we put the egg in an energy drink for 24 hours.

We were amazed by the results!

In the top picture the side that had toothpaste on stayed clear of the growth that stuck to the untreated side.

In the second picture we can see the way the energy drink had burned through the unprotected shell (on the left this time).

Our conclusion was that when we brush our teeth we shouldn’t rinse away the toothpaste.

We also tested some of our tooth brushing techniques with disclosing tablets but the results were too disgusting to share!

# Big sheet problem solving in Maths

Last week some of our children explored  addition and subtraction problems on ‘big sheets’.

The children needed to work together – often teaching each other as well as sharing ideas – in order to solve the problems.

The adults were hugely impressed by the way the children approached the challenge and the confidence they all showed.

# Exploring non-fiction texts in English

In Year 4 English this week we are examining, and then writing, non-fiction texts.

To start things off we have deconstructed a text about the Anglo-Saxons, identifying all the different features the author had used.

# Say cheese!

Sienna and Tayla shared a fantastic Victorian artefact with their fellow Year 5 classmates this week. Sienna’s family kindly let her bring in a precious camera made in the late Victorian period (when photography was first developed). We were extremely impressed by how they were able to set up the camera and explain how it would have worked.

It’s always great to see pupils extending their learning out of school. Well done girls!

# Young storytellers

In History, Year 4 children have been learning about the wonderful adventure stories the Anglo-Saxons told.

In this week’s English lessons the children have started writing their own stories and have been imagining that they are professional Anglo-Saxon storytellers performing their work to their classes.  The best ones have been rewarded with ‘gold’ and hearty meals but if their stories didn’t thrill their audience they were sent away hungry!

# Feel the Force(s) in Year 5

Year 5 have been exploring gravity and air resistance by designing and testing parachutes!

# Continuing Year 4 Science

Having left the eggs in a variety of liquids for 24 hours, Year 4 pupils looked at the results of the experiment and drew some valuable conclusions.

We found that some liquids would stain our teeth and others really damaged the egg shells (meaning they would damage the enamel of our teeth).  We even found that energy drinks seemed to do more damage than malt vinegar.  Yuck!

The one liquid that didn’t do any damage at all was water.

We will be continuing to look at diet and dental hygiene in our experiments.

# Year 4 Science ‘Egg-speriments’

In Science, the children are learning about the human digestive system.

Having learned how to describe the digestive system, we are now looking at how we can all help to keep the system healthy and functioning well.

We are starting with teeth, and are carrying out experiments (or ‘egg-speriments’ if you prefer) using eggs and a variety of different liquids to simulate the effects the liquids might have on our teeth.  After that, we will be experimenting with toothpaste to see if it really can help to clean and protect our teeth.

We will update with some of our results later this week!
