Diffusion

 A-Level Biology: Diffusion in Agar. Some tubes are filled with agar and an indicator, and the rate of diffusion of some acid is measured as it moves through the agar. By setting up a known series of concentrations, an unknown concentration can be determined.

Capturing the picture

MicroLab

 It’s that time of year when the micro lab comes out of its suitcase and shows the students what type of computer was used and available in the 1980’s. The micro lab was used to teach the students how to diagnose computer faults

Distillation

Students learning how to separate two liquids of different boiling points using the distillation apparatus. The students had to choose all the parts, assemble them and then produce their distillation products.

 

Trigger Dropper

 This is the new Smart Cart Trigger Dropper from @pascoscientific. It can be used for explosions by programming when to depress the trigger, showing the path of a dropped ball, and demonstrating conservation of momentum. On my wish list, now to see if I can get one

Probability

Fun with probability. What are the odds that one of the cards in a blue-backed pack will be red? What is the probability that all the cards can change to red backs? Magic and sleight of hand beat all odds.
 

Old ways of doing things

 With all the electronic equipment, is there still a place in the Physics lab for a ticker tape timer and analogue data recording, like cutting up strips of ticker tape paper to create a graph? There is, as it increases, a student's knowledge of how to do something.

In my lab, the students do experiments every time they come in, some big and some small. Science is all about learning how the world works. It is about why this does this and how we can explain it.
