The Chemist's tools 9.1.6 - The volume of a water drop
Matter: states and properties of matter.
Particle/kinetic theory, diffusion.
Pure and impure substances. Types of mixtures (solutions, oils, alloys, emulsions)
Separation techniques, including filtration, distillation [including crude oil - myp10], chromatography.
The size of an oil molecule.
This is a standard experiment using light oil on a flat surface covered by lycopodium powder.
Part of this will discuss how to measure the volume of an oil drop.
Experiment to investigate a factor that could affect the volume of a water drop.
The maths while simple can cause confusion in the less able students. Shape diagrams for cylinders and the oil drop on the surface are essential.
Pre-knowledge of maths skills is useful.
