Thermal expansion making up solutions.

 When making up solutions - why is the temperature so important. Students made up a solution of NaOH to the correct molarity, then after cooling, they saw that their perfect solutions weren't so perfect after all. Lesson Learnt.

Plancks Constant Apparatus

The last two LEDs on the Plancks constant apparatus are in the IR and invisible to the naked eye but easy to see with a phone or a digital camera. Should we use the camera to obtain readings for these values, as the camera might give different weights to the human eye?

Convex lens to explain ripples

Explaining to students why the ripples in a ripple tank look the way they do by using a convex lens to show the thicker parts of the wave are lighter because it is concentrating the light and the thinner parts are less white because they are more spread out.

 

Quadrat

Using the camera quadrat to survey a transect across an area of grass, close to and far away from a tree, looking at the different plants growing at different distances. All use the same data to analyse. Excellent use for AI to count and identify.
 

Inside a computer

 It doesn't have to be a computer because it contains a motherboard and processor and RAM in it. This motherboard is in an electronic organ. It is a computer but it is not quite what a student expects to see.

Required Practical

No matter how many students I have and from many different schools, the number of students who have not done the required practicals or seen a demo of them. Many have just seen a video online and forgotten it almost as fast as they saw it.
