“Look deep into nature, and then you will understand everything better”
- Albert Einstein
Our main aim in Science is to convey to students that Science underpins everything.
At Chorlton High School we study:
- Physics to be able to understand the fundamental principles that govern all energy and matter in the universe. Physics gives us tools to understand nature, from the scale of sub-atomic particles up to the inter-galactic scale of the universe.
- Chemistry to be able to understand the nature of substances: how they are composed, their behaviour, and their physical and chemical properties. Chemistry allows us to identify unknown substances, monitor concentrations and synthesise new chemicals. Above all, Chemistry is about finding solutions to the problems that concern us and our surroundings.
- Biology to be able to understand life and thereby understand ourselves. Biology allows us an understanding of the amazing complexity of many life processes and mechanisms. Biology encourages us to seek out reasons for strange, surprising and sometimes unusual observations.
First and foremost, we are proud of the results that the Science department consistently achieve.
In 2020 the % of students achieving a grade 5 pass or above was:
- Biology - 97.3%
- Chemistry - 98.6 %
- Physics - 98.6 %
- Combined Science - 53.6 %
These are our best results yet and we continue to steadily improve year on year.
This success is down to the hard work and passion of the Science teaching team. This success is testament to how hard they work to produce and deliver a curriculum which is accessible to all our students at CHS.
Our curriculum is tailored so it is engaging for students throughout their 5 years at Chorlton High School.
The curriculum we have developed includes as much practical work as we can include, especially in Years 7, 8 and the start of Year 9. This to enable us to capture a student’s fascination for Science and how things work. We then build on this throughout the Key Stage 4 AQA Separate Sciences or Combined Science Trilogy.
Our STEM club thrives with about 30 to 40 students attending regularly. In STEM club students carry out practicals and projects including building a glider with 2m+ wingspan, a hovercraft and presently we are looking into the practicalities of building a go-kart!
Make Your Own Quick Sand
Quick sand is a fascinating substance, make some of your own and experiment on a safe scale. Amaze your friends by demonstrating how it works.
What you'll need:
- 1 cup of maize cornflour
- Half a cup of water
- A large plastic container
- A spoon
- This one is simple, just mix the cornflour and water thoroughly in the container to make your own instant quick sand.
- When showing other people how it works, stir slowly and drip the quick sand to show it is a liquid.
- Stirring it quickly will make it hard and allow you to punch or poke it quickly (this works better if you do it fast rather than hard).
- Remember that quick sand is messy, try to play with it outside and don’t forget to stir just before you use it.
- Always stir instant quicksand just before you use it!
If you add just the right amount of water to cornflour it becomes very thick when you stir it quickly. This happens because the cornflour grains are mixed up and can’t slide over each other due to the lack of water between them. Stirring slowly allows more water between the cornflour grains, letting them slide over each other much easier.
Poking it quickly has the same effect, making the substance very hard. If you poke it slowly it doesn’t mix up the mixture in the same way, leaving it runny. It works in much the same way as real quick sand.
Cut Ice Cubes in Half Like Magic
Speed up the melting process of ice with the help of a little pressure. Cut a piece of ice in half like magic while learning how the process relates to ice skating.
What you'll need:
- One ice cube
- A piece of fishing line with a weight (the heavier the better) tied to each end
- A container
- Some kind of tray to keep things from getting wet
- Turn the container upside down and put it on the tray.
- Place the ice cube on top of the upside down container.
- Rest the fishing line over the ice cube so that the weights are left dangling over the side of the container.
- Watch it for around 5 minutes.
The pressure from the two weights pulls the string through the ice cube by melting the ice directly under the fishing line. This is similar to ice skating where the blades of a skater melt the ice directly underneath, allowing the skater to move smoothly on a thin layer of water.
