Measuring Radioactivity

 You can't see it, taste it, or smell it, but with the @pascoscientific Wireless Geiger counter, you can hear the radiation and see the results plotted on a graph. The students were really surprised about the amount of background radiation.

Argand Diagrams

 Investigating the modulus and the argument for displaying complex numbers. Getting a good foundation in numbers helps much later in Further Maths.

House Heat Loss

 

Today is a good day to examine the heat loss from the house using a Thermal Camera. These pictures are handy for all the Physics lessons when investigating insulation.

Ultrasound to look for veins

 Studying circulation becomes a bit more interesting when an ultrasound machine is used to scan for a vein so a cannula can be inserted into an arm. We also learned why needles are put into veins rather than arteries.

Complex Cubic Root

Having some fun with math—solving a cubic equation with one real root and a pair of complex conjugate roots. Exploring the fascinating interplay between real and imaginary solutions! #MathFun #ComplexNumbers #CubicEquations

Fibre optics

The students are examining a fibre optic model to determine how total internal reflection works, how a signal can be sent down, and why monochromatic light is needed when messages are sent down the fibre.

Prep Roots for the Microscope

 

Preparing some root shoots for examining mitosis under the microscope—a long practical involves repeatedly dipping the roots alternatively in Acetic Alcohol, 60C Acid, and Iced water before macerating them and dying with Orcein Stain.
