Eclipse


 In Physics, we explore why eclipses don’t happen every month — despite regular new and full moons. We also look at how the Moon’s changing distance from Earth creates different types of eclipses and how this is all controlled by gravity and angular momentum..

Capillary Rise


 How does transpiration work, and how does capillary rise help the plants? We investigated the bores of different-sized capillary tubes to find out the effects of having smaller bores.  The smaller the bore, the higher the rise. Next, to measure the size of the xylem cells.

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.

Momentum inline and stacked

  Inelastic collisions comparing one @pascoscientific smartcart hitting two stacked and two inline. Does it make a difference? Not much sinc...
