Runny Liquids - Teachers' Notes

The activity is primarily about fair testing in investigations, and requires children to work through a series of challenges to assemble factory equipment to produce a cough mixture.

In order to gather the pieces of equipment, they must answer questions about fair testing, make observations, time activities on video clips and interpret data.

There are four challenges:

Challenge 1: A fair test to measure runiness

Challenge 2: Using timer to measure runiness before and after warming

Challenge 3: The best way to move liquids about

Challenge 4: Choosing apparatus to test the runiness of the mixture

A final page summarises the activities.
