Making Ammonium Sulfate

 

Creating our own fertilizer from Ammonium Hydroxide and Sulfuric Acid by titration and using Blue Litmus to work out the endpoint, then crystalising the solution to make our fertilizer to test on some plants.

Quick Electrics

"I have a test on electrics tomorrow and I can't remember a thing, can we go over all of A-level electrics in 1 hour." With some @MatrixTSL locktonics and @pascoscientific, we did it all.

Integration Tricks

Integration Tricks. If the top number in a fraction is the differential of the denominator then the quick trick of writing down ln|f(x)|+c makes the integration so much faster than using substitution or parts.

 

Hydrometer

 I was surprised how few students had met a hydrometer before. A simple experiment making different strength sugar solutions and measuring their strength using the hydrometer.

Osmosis and Visking Tubing.

 Osmosis and Visking Tubing. It took overnight to run but we managed to get the water to enter the bag fill it full and push the level up the tubing. An hour in the lab was not enough.

Design and Patents act

 Attempting to make Copyright, Designs and Patents more exciting. Learning about what they can do without breaking copyright laws.

Calipers

 Ask a student to measure something, and then they will grab a ruler. But sometimes we need to be more accurate, and in comes the Vernier or Digital Calipers, something many have never met before.
