An Aspiring Champion for Team GB
Meet Lilly Williams-Howell, a talented young skater from Prestatyn, in North Wales.
Lilly, who is now 11 years old, has been skating since age 7, and is now very close to realising her dream of representing her country. After a lot of training and practice, she now has the chance to skate at an international competition for Team GB. We talked to Lilly a little bit about her skating, and her hopes for the future.
A Trip to Mars!
Imagine being able to catch a flight to Mars as easily as we travel to another country – that was the idea behind the Trip To Mars session I attended at the Cheltenham Science Festival. It was conducted by Dr Suze Kundu and Dr Simon Foster and presented as a pre-flight safety briefing, with both of them dressed as pilots! There were a lot of humorous moments and sci-fi references but also some great science.
Suze and Simon suggested that in the future, flights to Mars could be far quicker than they are now, and explored how some of the bigger problems could be overcome. For example, the Sun’s magnetic field deflects a significant proportion of the cosmic radiation that could be harmful to humans on Earth; as spaceships travel further away from the Earth and Sun they will have less protection because the magnetic field weakens. To combat this it’s possible that spaceships will contain or be covered with large and powerful magnets, to produce the same deflective effect. This would have the added advantage of also deflecting radiation from solar flares.
Spaceships journeying to Mars would travel at such speed that even tiny fragments of rock and dust could be damaging to the hull. To combat this, and also the heat generated when the spaceship passes through an atmosphere, Suze and Simon discussed the possibility of spaceships being coated in aerogel. This amazing material is a solid formed from silicone dioxide but is 98% air; this means that it is extremely light but also strong. Its melting point is 1,200°C (equivalent to asbestos) and it is a wonderful insulator. Because it consists of large pockets of air between thin layers of silicone dioxide, any dust or rock fragments that hit it would be slowed and stopped before they could penetrate the aerogel completely.
Suze and Simon also discussed the possibilities and problems with cryostasis. Theoretically this is when a person’s body is cooled to temperatures so low that they enter hibernation, ideal for long journeys through space. Unfortunately our technology isn’t advanced enough to do this at the moment; any attempt would result in the cells rupturing and the person dying. But in the future it will be possible, perhaps after the person’s DNA has been altered slightly so that they can produce antifreeze proteins like some species of wasps and turtles.
Stories From The Stables – Sam

I fell off, honest
Learning to ride is a fabulous hobby. It can be pricey, but you can borrow a hat and crop from most stables, and start off in trousers and strong shoes. It is great exercise, very exciting, and teaches respect for animals, balance, and correct posture.
When I was very young I rode at Stourton Stables, a children’s riding school where the ponies were mostly grumpy and had to be separated in the fields for fear of kicking each other to pieces.
Oh, happy riding lesson days. Hours spent in icy pouring rain, in snow, in fog, and even more rarely; in lovely sunshine. The best riding times of year for me were spring and autumn, before and after the major insect season.
Tween Chef – Simple Solo Cooking for Kids
Simple solo cooking – learn how to make these dishes with minimal assistance from adults.
We recently noticed that there are LOADS of “cooking with kids” videos on YouTube but not many of them feature kids doing all the cooking. Often they are only allowed to stir things, or decorate the cakes. Most tweens are capable of cooking the entire meal, but often they lack confidence, or are worried about burning themselves, or spilling things.
You will learn basic cooking techniques, and how to stay safe in the kitchen, and as time goes on we will do more complicated dishes.
How Much Sleep Do Kids Need?
Julianne Robertson investigates the world of snoozes, forty winks, cat naps and snoring. What is SLEEP, why do we need it, and how much sleep do kids need?
A couple of nights ago I was feeling really, really tired, so I went to bed early. I slept soundly, without even dreaming, until about 5am, when I woke up. It felt like I’d only been sleeping for about 5 minutes! After that, I fell back to sleep but had lots of vivid dreams and when I woke up a couple of hours later, it felt like I’d been asleep for a long time. After all that I still felt well-rested and was ready for the day.
All this made me wonder – what IS sleep? Why is it that some nights we feel like we’ve had a really good nights’ sleep, while other nights we still feel tired when we wake up in the morning? Here’s what I’ve discovered about sleep…
