ROEDEAN’S STEM FESTIVAL 1 OCTOBER 2019
STEM stands for Science, Technology, Engineering, and Mathematics. These four disciplines share a great deal of common ground - as a result, there is often an applied and interdisciplinary approach to them as a group. The elements of STEM are commonly seen as fields where there is a shortage of skilled experts, particularly women. However, Roedean has a long and proud tradition of educating young women in scientific and mathematical disciplines, going all the way back to one of the Lawrence sisters who founded the School. Roedean is very fortunate that Dr Suzie Imber, Professor of Space Physics at the University of Leicester, is our STEM Ambassador, and she is presenting a lecture as the finale of today’s Festival. We hope that you have a wonderful day, and that you will perhaps be inspired to pursue STEM in the future!

ROCKET-FUELLED CHEMISTRY Rocket fuel works on the basis of Newton’s Third Law of Motion, which states that ‘every action is accompanied by an equal and opposite reaction’. By firing fuel out the back of a rocket, the force propels it upwards with acceleration equal to the force at which the fuel is expelled. It is almost identical to how a jet plane is able to fly in the atmosphere. However, one difference is that jet planes use oxygen in the atmosphere to ignite their fuel, while a rocket must carry its own oxidiser. Today you’re going to look at two chemical reactions that could be used by rocket scientists to produce a fuel (hydrogen) and an oxidiser (oxygen) for use in their rockets. We’re even going to use them to launch our own rocket in the lab! Brain Teaser Who created the Periodic Table? 4
SCIENCE
QUESTIONS
– They are rocket science!
Reacting hydrogen and oxygen What do you get when you react hydrogen with oxygen?
What is the formula of this substance?
Where is this reaction used?
Making oxygen Mixing hydrogen peroxide with manganese oxide forms oxygen gas. How did you test the oxygen you made?
How do substances burn in pure oxygen compared to air?
What is the percentage of oxygen in air?
Making hydrogen Which two substances did you mix together to make hydrogen?
What do you use to test for hydrogen gas?
What is the result of this test? 5
ECH NOL OGY Design and Technology teaches you about different materials and their properties as well as structures, systems, mechanisms, electronics and programming. It teaches how to take an initial idea through to a completed product using design and manufacturing skills. This naturally integrates Science, Maths, Engineering and Technology in the Designing and Making of useful products. Brain Teaser What is the main source of hydro-electric energy?
TASK Often design is used to improve existing inventions. You will be provided with the basic parts of a balloon powered car and challenged to improve upon the design. Task 1: What aspects of the car design do you think most need improving? Test the car before rating the list from 1 to 5 (5 for most important, 1 for least):
6
• Speed
• Appearance
• Ability to carry something
• Durability • Steering
TECHNOLOGY
Task 1: Attempt to improve the design of the car in one of the ways above. Tick the resources that you used from the list below: • Masking tape
• Plasticine
• Rubber Tyres
• Paper
• Tin foil
• Copper Mesh
• Coloured card
• Fabric
• Cardboard
• Lolly sticks
• Tissue paper
• Paper straws
ANALYSIS Which improvement do you think is most vital? Why?
What did you do to improve it and did it work?
Did anyone else do the same?
Can you think of any additional improvements?

What is the hardest substance in the world?
ERING DESIGN BRIEF Your challenge today is to work as a team to build the tallest possible structure you can, using only spaghetti and marshmallows! Have a think about the buildings in the photographs and what makes them tall and strong... You have a limited amount of time and building resources. Your structure must be able to stand on its own for at least 30 seconds. How many centimetres tall was your spaghetti tower?
Write down two important ways in which structures can be made strong and stable: 1.

When you’re building a tower, there are What is so many things you need to think about e=mc2? to make sure that it is stable - designers use Mathematics and Physics to work out the forces, and Technology to make sure that the correct materials are used too! Look at these 6 tall buildings and see if you can put them in the correct order from tallest to smallest (1=tallest and 6=smallest):

ATHE MATICS THERE ARE ONLY 10 TYPES OF PEOPLE We use a decimal system for counting, meaning that we count in tens. However, would we count differently if we had 8 fingers and thumbs? Or 17? Probably. We count days in sevens and hours in twelves or twenty-fours, and some cultures count in fours, nines or even sixties. All computers use two ways of counting: binary (counting in twos) and hexadecimal (counting in sixteens). BINARY The binary system was invented in 1679, by Gottfried Leibniz, a German mathematician, and is now widely used for almost all computing and electronic systems. It is how your favourite film is stored on a DVD, and is what tells your mobile phone what you have just pressed. Binary is everywhere. Most people don’t know how to use it, yet it is surprisingly simple to understand. Brain Teaser What do we call a2 + b2 = c2? 10
