Crushing Can

Crushing a can by the removal of air. An oldie but a goodie. The students didn't realise air and air pressure is as powerful as it is.

Engineering Physics

 Students find out that Engineering Physics is fun, looking at gyros, the drinking birds, using a manometer, water held in a glass by paper and a firestarter.

Gay-Lussacs Law

Gay-Lussac's Law: Investigating the relationship between increasing pressure as the temperature increases for a fixed volume of Gas using the @Pascoscientific pressure sensor and the wireless temperature sensor. I tried this with a Bordon gauge but didn't see enough movement. In 1802, he discovered that when a gas is heated, its volume increases at a constant rate. He also found that when a gas is compressed, its temperature also increases at a constant rate. These two discoveries led to Gay-Lussac's Law of Pressure-Temperature, which states that the pressure of a gas is directly proportional to its temperature.

Coloured liquids showing density

Adding different amounts of sugar to water and dying it. Put the most dense at the bottom and then carefully pour the less dense liquids on top one at a time and we get pretty layers which diffuse together over time

 

Too much time on Practicals

It used to take ages to set up the circuit then, record some values and then graph them. I don't have time for this, so for the properties of resistors and bulbs and diodes the @pascoscientific voltage current sensor records everything in seconds and plots them. Perfect.

 

Whoosh Bottle

A-Level Chemistry one of the properties of Alcohol is that it burns - No far better get out the whoosh bottle and fill it with a bit of alcohol, shake and then ignite. Much more fun, and then lots of discussion on rockets.
