TLF ID A006044
In this activity, students investigate the properties of familiar liquids by comparing how they behave when dripped onto a coin. They investigate a range of household fluids, like tap water, soapy water and oil; they predict and observe how the liquids behave when placed in drops on a coin, and are challenged to change variables (such as temperature) and observe the results. The activity includes a list of what is required, suggestions of what to do and notice, questions to ask, an explanation for the underlying science of what students observe and suggestions for other related activities.
