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.

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!

 

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!

Taking responsibility for learning in Maths

In Year 4 we completed our first unit of Maths, learning about the place value of numbers.  To help to count in 3s, 4s, 5s and 10s (including using negative numbers) the children used a variety of resources, really taking responsibility for their own learning.

Dicey times in Year 4

Amongst some super work in Maths this week, Year 4 children have been using dice games to learn about counting using negative numbers.

Year 6 Bikeability

As part of their ’Golden Half Term’, our Year 6 children have been taking part in Bikeability training within school, and also out on the local roads.  

Budding Lizzie Deignans and Chris Froomes have been making sure they can ride safely – an important life skill as they become more independent.
