Gases laws.
In these experiments students work on the behaviour of gases in relation to different variables: Temperature, pressure and volume.
Although not all of them are related with the Boyle, Charles and Mariotte´s laws, all of them have been funny and interesting.
Here’s kitchen chemistry that turns a solution of sugar and water into a tasty treat.
Crystallisation: The compound that we wish to obtain must be soluble in a hot solvent and not very soluble in the same solvent when cold.
We work on different concepts: Solubility and saturated and oversaturated solutions.
