Horse Chestnut

We have been measuring perimeter using these shapes on the floor. The children did really well extending their thinking finding different number sentences to find the perimeter. 

We were lucky enough to have Thomas, who is a weapons engineer, from the Royal Navy to come speak to us about the Navy in Portsmouth and why it is so important. Some questions we asked are:

Child- Have you ever sunk a ship?
Thomas- We have sunk pirates off the coast of Somalia. 


C-What was the Navy created to do?
T- To originally protect the English from the Spanish and French 500 years ago but now we protect the oceans around the world. 


C- What is the biggest ship?

T- The largest ship is the Queen Elizabeth, which came into Portsmouth before it started it's sea trials. 



Thomas also spoke about how the Royal Navy is a wonderful job to have and if you work hard at school you could go and do that also!

A Clean Sweep!
Horse Chestnut class managed to win the PE and tidiest classroom award. Well done for all the effort respecting our school environment and bringing in all their PE kits. Next week maybe we could win the attendance award and make it a hat-trick

We have been making the most of the fabulous grounds we have and going pond dipping to record different insects. We found mallards, blue beautiful damselflies (not to be confused with a dragonfly) and a green insect from the pond with bright red eyes that we have not been able to identify yet! We also used the data loggers to record the temperature and will draw comparisons between the insects we found on different days at different temperatures. 

The results are in...
Horse Chestnut class are rather good at brushing their teeth!

We used plaque tablets to look at the tartar and plaque on our teeth, which turned up a light pink in the dye. There are a few children though, who have agreed that they could spend longer brushing their teeth each morning and evening to get rid of that bacteria (plaque). We know that the bacteria will turn all those sugary treats into acid which will wear away our enamel and create cavities. 

The results from the plaque tablets are in...

Brush those teeth for next week...
This week we have been exploring the different teeth, their names and uses. We have learnt how to look after them and that any sugar we eat feeds the bacteria on them creating the acid that can cause cavities. We are doing an experiment to see which lquid (orange juice, cola or water) dissolves the egg the most (the shell is the enamel and the acid the bacteria produce is recreated by the liquids). We will find out the results next week and also use some plaque tablets to see how well we have been looking after our own teeth! Lets get brushing...

Get brushing!

Proud Teachers Alert!

We were so proud of this year 4 pupil. He excellently prepared his reasons, at home,  why we should adopt the turtle and spoke clearly and persuasively to the class. He came a very respectable second place and got all the votes from the adults! He felt so strongly that he went home and his Nan adopted the turtle for him. We're so proud that he is contributing and making the world a bit of a better place. This is the turtle he was sent from the WWF. Keep it up.

We have been learning about deforestation in science and looking and the effect humans have had on the habitats of different animals. We have used the WWF (World Wildlife Federation) as a source to research different problems the animals face. Year 4 were desperate to do something to help the planet after learning about the impact of humans they held a debate and voted on which animal they would like to adopt as a year group. We decided to protect an Amur Leopard from Russian and have received our pack in the post! We were so excited to read about our animal and find out how our money will help protect them.

As part of our science topic we were lucky enough to have a virtual reality company come in to show us a range of micro habitats and their animals. We will use this in our learning to go on to classify the animals and create our own classification systems. One child commented "It felt like you were right there" while another said "I learnt that rhino beetles can grow very large and a praying mantis is very difficult to see".
