Building Computer Race

Practice is over. The teams are set. All have the same hardware to assemble, the motherboard, processor, RAM, Graphics card and USB Board, but who can assemble the parts, install the Operating system and hook up to the network the fastest.

Making Butanoic Acid

 Making Butanoic Acid from Butanol by refluxing with acidified Potassium Dichromate and then distilling the Acid into a conical flask for later experimentation. Getting students to learn skills by building the apparatus from scratch and discovering all about ground glass joint laboratory equipment.

Circuit emulation

 Setting up circuits in @pascoscientific Capstone, to emulate different electric circuits. Faster than building the circuits for electricity revision, the emulators can calculate the resistances, current and voltages.

Looks like Maths

Many of us have a compartmentalised brain—Chemistry is Chemistry, and Maths is Maths. When students find an easy Maths problem in Chemistry, it is suddenly more difficult because they perceive it as the wrong subject.

Measuring the Speed of Sound

 Measuring the speed of Sound using a tuning fork and a tube, pulling out the slider until the loudest sound can be heard and measuring the distance from the tuning fork. This gives the wavelength. Repeat this several times to get a good average, and then work out how much of a wavelength the distance is calculated at the velocity of sound in air at this temperature.

Site of Respiration

 The Mitochondrion is the site of respiration. Is this an ancient bacterium that invaded another in an example of symbiosis that created a new type of organism? DNA Evidence? Mitochondria self-replicate.

Calculating Depreciation

 ​In Business, depreciation refers to the gradual decrease in value of an asset over time due to factors like wear and tear or obsolescence, and it's a key accounting concept used to allocate the cost of an asset over its useful life.
