Science Technology Engineering Mathematics
Welcome to the STEM web page. At West Chiltington School, we would like all our children to nurture a keen interest across these subjects.
However, we are aware that recent statistics show that in the UK: women make up only 8% of engineers; only 10% of managers in STEM careers are women; and only 10% of STEM businesses are owned by women. If we bring this analysis back to education: 49% of state schools send no girls to study A-level physics, and of those students who are taking an A-level in the subject, only a fifth are girls - despite getting similar grades at GCSE as boys.
We have set up this web page to highlight the work that the school and parents are doing to bring STEM opportunities into the classroom and at home for all children in order to encourage their interest.

This week's STEM assembly:
Hot or Cold ?
In assembly we looked at what happens to air when it gets heated or cooled. We learnt about the molecules getting more energy when they were heated up, which meant they moved quicker and spread out, making warm air less dense than cooler air.
The experiment we did was similar to this one where we used water rather than air, which behaves in a similar way and is a bit easier to control! If you want to repeat the experiment at home remember to get an adult to help with the hot water. Better still, maybe you want to set up your own experiment to see what happens with different temperatures of water. As always, please send in photos, videos, drawing or writing for any science you get up to at home!
Hot air balloons
Hot air balloons are filled with ordinary air that is heated with a gas burner. The gas doesn't make the balloon fly itself, but it heats up the air inside the balloon. The air gets more energy and expands making it less dense than the cold air around it. The warm air is lighter and so it rises up.
How does the pilot make the balloon come back down?
Warm air currents
You can't see warm or cold air, but you can see the effect it has. Try this at home: In a cold room, put a heater on. Blow bubbles across the top of the heater and watch what happens. Can you predict what will happen to the bubbles? Why did that happen?
Air can vary in temperature and also how much moisture it has in it. Yellow class have been learning about what air conditions are needed for hurricanes to form – click here if you think you could create a hurricane!
Hot and cold air/water websites and videos:
It turns out that birds are sci-entists too! See how they use their learning about warm air rising to help them fly on this video.

From CBeebies this week: 6 ways to help children think like engineers
A wonderful article here from the CBeebies website with some great ideas for how to get younger children engaged in STEM activities.
Car launched into space!
Continuing the theme of strange things launched into space this week. Elon Musk has launched his own Tesla into space in a spectacular launch on 6 February.
For more information and video clips on the launch please see The Guardian article here .
Disco ball launched into space!
New Zealand has launched a disco ball into space which orbits the earth every 90 minutes and is visible from Earth. They have called it the Humanity Star and have launched it to create a shared experience for everyone on Earth. Humanity Star is designed to be "a bright symbol and reminder to all on Earth about our fragile place in the universe". You can read more about it in the BBC article here.
STEM Boxes.......are here!
STEM boxes are self-contained fun experiments in a box that your children can take home with them from school. They contain the instructions and all the equipment that you and your child will need to try the experiment. They also contain feedback forms which we will read when you return the box to help us develop the boxes further.
If you haven't yet taken a box, or you would like to take a new one, remind your child to take one or feel free to pop in before or after school and sign one out from the cupboard in the craft room. If you're unsure where to look, just ask.
Yellow class are currently learning about space and two interesting questions have come from the class:
Why does the moon change shape?
I found a good children's video on YouTube to explain it here.
As well as learning about the moon, the question also raises good topics such as light travelling in straight lines, and how it reflects off of some things, and can lead to further experiments with torches and mirrors.
Why are planets round?
A very interesting question introducing the concept of gravity. See here for a great children's space website explaining the answer.
Where are we in the whole universe?
There is a great answer in this amazing video sent in by one of the Yellow Class parents: video.
Please send your children's questions (and any answers you have found if you have them!) to firstname.lastname@example.org.
Please send us your pictures of your children enjoying STEM activities.Charlie & Rupert Head-Parsons (Purple & Green), trying out the 'Fun with density' STEM box at home. They loved working out whether each ingredient would sink or float.
Poppy Hearnshaw (Green Class) enjoying the Make Your Own Volcano experiment: "Poppy had great fun making the volcano. After completing the experiment we went on to have lots of fun with our own ingredients."

Cool maths trick for remembering 9 times tables:
Here is a mind-blowing maths trick It goes like this for remembering your 9 times tables.
Example: 9 x 3
Put both hands up with 10 fingers/thumbs. Put your third finger from the left down on your left hand. Then count the number of fingers on the left side of that finger (here you get 2) and on the right side of the finger (you get 7). Put those numbers together (27) and there's your answer. 9 x 3 = 27.
It works all the way up to 10 x9. So cool.
