If you were asked to describe a robot 10 years ago, you might have come up with something along the lines of a large silver box covered in lights and dials, with 2 arms, 2 legs and a human-like head – the reality of modern robots is of course quite different! Robotics and electronics in our daily lives are becoming more prevalent by the day, not just in labs and factories, but at home and in the office as well.
Workshops in Bedford for Home-Educated Students
In October and November we enjoyed running a couple of different workshops on light. The first one was “Light, Lasers & Illusions”. During the presentation the children discovered how our eyes can be tricked, how we can burst balloons with different coloured lasers, and how a drop of water can be turned into a simple but impressive microscope.
We also introduced them the power of UV light and concepts of fluorescence and phosphorescence. During this workshop they also developed their own photography using a special paper and UV light.
The second workshop was related to fibre optics. As an introduction we explained to them some basic concepts such as reflection and refraction.As always we wanted them to see these phenomena by themselves which is always better than a presentation to get them interested. That is why we prepared some demonstrations and experimentedusing lasers, mirrors and some flour to see what happens to the laser beams. They made a useful periscope to spy without being seen and a fibre optic torch that they can use as a light or communicate using Morse code. They also enjoyed a live show using our Tesla coil, which needs fibre optics to work because of it is impervious to electromagnetic interference.
