I have added rough times for the images below. They are organised by group(s) for the two separate SD cards that were used. If you do not see your photo in the top, please make sure to scroll through to the bottom for the other SD card.

Science meets art: painting with ferrofluid
Ferrofluid, as described here in greater detail, is a suspension of iron oxide nanoparticles that are so small, that they align themselves immediately with an applied magnetic field (superparamagnetism). This results in a spiky pattern that gives an indication of the position of magnetic field lines, which I like to refer to as the ‘hedgehog’.
If you inject a water based paint into the ferrofluid, when a magnet is held on the other side, you will be able to form domains of colour suspended in the fluid – as seen above.
Can you see the double rainbow?
Ever noticed how the order of the colours changes for the second rainbow (red – yellow – green – blue – violet…)
Typically rainbows are formed when light is refracted (bent) through a raindrop.
A double rainbow forms when light is refracted twice in a raindrop, and occurs commonly when the sunlight is low in the sky. See here for more.
I will be adding resources here as I find them – mostly Maths and Physics themed.
Online Mathematics Course
Loughborough’s Mathematics Education Centre runs a free, three-week MOOC – Getting a Grip on Mathematical Symbolism – designed for those students aspiring to become scientists or engineers but who lack mathematical confidence.
It will run again on the FutureLearn platform starting May 8th. Registration is open now:
Magnet Academy is an online resource provided by the National High Magnetic Field Laboratory — the largest, most high-powered magnet lab in the world. It has a wide selection of useful tutorials about electromagnetism for ages 5 upwards.
British Science Week
As part of British Science Week, Loughborough University hosts a ‘Community Day’ event where Loughborough locals are invited on campus to take part in various ‘science based’ activities.
This year it falls on 25th March I will be:
- Coordinating an Electrodough workshop – for which we’re looking for student ambassadors.
- Running a ‘Cold Science’ demonstration with liquid nitrogen.
- Working with the East Midlands Institute of Physics to deliver several ‘busking’ activities – for which I’m looking for student ambassadors.
If you’re interested in getting involved please let me know.
