The school was delighted to have received a letter from Nick Gibb MP, Minister of State for School Standards, congratulating us on our Progress 8 figure 2016/2017 which places the school in the top 5% for progress. This is a fantastic achievement given that students already enter the school achieving at a very high level.

Do you have any devices that contain lithium batteries? The chances are that you do. Lithium ion batteries are very common in the technology industry and are used in cameras, watches and smartphones, so it’s very likely that you come into contact with them on a daily, if not hourly, basis.
However, they are also known for being hazardous and in the most extreme cases, explosive. One frequently reported example is the Samsung Galaxy Note 7: there have been 35 confirmed cases of the battery catching fire. Yet, in defence of the lithium battery, only 1 in 10 million lithium-ion batteries are likely to malfunction. In fact, you are more likely to die in a car crash (a 1 in 10,000 chance ) than get injured by a malfunctioning ion battery.
It was reported just last week that a woman who was wearing headphones powered by lithium batteries was injured when travelling on a flight from Beijing to Melbourne. As she was listening to music, her headphones started sparking and caught fire. She was left with a blackened face and blisters on her hand.
But why do lithium batteries explode? A lithium-ion battery is made up of power-generating compartments called cells. The cells are made of three components which are a positive electrode, made of lithium-cobalt oxide; a negative electrode, which is made of carbon; and a chemical called an electrolyte. As the battery is charging up, the positive electrode gives up some of its lithium ions. This moves through the electrolyte to the negative electrode, where it stays. The battery takes the energy in and stores it during this process. When the battery is not charging, the lithium ions move back to the positive electrode from the negative. This produces the energy that powers the battery.
Problems occur when the batteries are charged too quickly. This can create lots of heat and, eventually, a fire. Lithium batteries have built in electronic controllers which control the speed of charging to try to prevent this problem – but clearly this is not always effective.
Several students at Colchester County High for Girls said they were worried that their phone or charger could explode. Gimhani, 14, said, “My parents always tell me not to leave my phone charging for too long as it might catch fire”. Bridget, 14, said, “If my phone overheats, then there is a small chance that it will explode.”
Whether or not you decide lithium batteries are too dangerous for use, it would be hard to stop using them. Lithium batteries are in all types of phones, not just Samsungs. But students should be reassured that, while there is a small chance that their phone battery could catch fire, it is extremely unlikely.
Dame Vera Lynn is to release a new album to mark her 100th birthday, which she will celebrate on 10th March.

Additionally, other well-known British singers such as Alfie Boe, Alexander Armstrong and Aled Jones will cover Vera Lynn’s war time hits.

Last week, three teachers from Colchester County High School for Girls tackled the gruelling Colchester Half Marathon. On Sunday 12th March, science teachers Miss Murison, Miss Jones and Miss Morgan completed the 21km route, running through Colchester on a challenging course that began at Colchester United’s Western Homes stadium. After several months of practice and training, the three heroic teachers completed the task with flying colours, collectively raising over £700 for their respective charities: Mind, Cat Rescue and the Catherine Bullen Foundation.

The Department of Education has proposed an idea to introduce an hour of “happiness” into all UK schools, with the aim of improving the self-esteem, confidence and overall happiness of children of all ages.
The idea, referred to as “happiness lessons”, campaigns to improve the mental health of Britain’s youth, especially adolescents.

At lunchtime today, 9H held a bake sale in aid of their form’s charities. It was a roaring success.
At CCHSG, students take pride in raising money for charities of their choice. It has become school tradition to raise money by hosting a bake sale, selecting a particular theme be it Halloween, Christmas – or Oreos. It is always exciting to see what students will come up with next.

Artist Emma’s impression of how the housing development may look
Although Colchester is proud to have been named by the Essex Property Network as one of the fastest developing towns in the UK, in February 2017 disputed plans for a new development of 122 homes on Bakers Lane were revealed. However, despite the fact that these plans are yet to be confirmed, residents of the area are infuriated and strongly oppose the idea of this proposal.

It’s been nine months since the UK made the decision to leave the European Union (EU) and with Prime Minister Theresa May insisting that Article 50 will be triggered by the end of the month, one question is remaining: Could Brexit really result in the breakup of the United Kingdom?
