These downloadable animations are part of the multimedia package Stuff and Substance, developed by the Gatsby Science Enhancement Programme (SEP). They can be used to introduce density as a property to identify substances.
The first animation introduces the idea of density by comparing the masses of equal sized blocks of different substances. Students are challenged to put six familiar substances in order of increasing mass. A balance is there to help if needed. In the second animation, students perform an experiment to find the density of three crowns and identify which is not gold (NB It needs to be used in conjunction with data on densities as given in the Stuff and Substance package).
These video and animation files form part of the resources in the section Density in the Stuff and Substance multimedia package, which provides a series of interactive pages that can be used by teachers or students in the classroom.
HEALTH and SAFETY
Any use of a resource that includes a practical activity must include a risk assessment. Please note that collections may contain ARCHIVE resources, which were developed at a much earlier date. Since that time there have been significant changes in the rules and guidance affecting laboratory practical work. Further information is provided in our Health and Safety guidance.
