What really is a mixture?

In this hands-on science workshop your primary students will investigate all manner of suspensions, colloids and solutions to find out different ways of separating mixtures. Filtration, chromatography, magnetism, centrifugation, evaporation and chemical separation techniques are all explored...are they physical techniques or chemical techniques?

The presenter was enthusiastic and animated about all things scientific... his presentations were exciting for the students. The programmes specifically suited the stage level and worked perfectly. A very valuable resource.
