School children doing the laundry by hand? Sounds like a return to the Victorian classroom. Not with this engaging lesson, which uses a tablet, a lux meter app and good old-fashioned soap and water.
This lesson encourages the children to be critical thinkers about advertising claims made by washing powders. With the use of science, they can either support or refute these claims using their results.
The different claims made by washing powder manufactures provide a wide range of exciting investigations which can easily be completed within a classroom.
Students will learn
- Scientifically test claims made by companies about their products
- Measure light levels (in lux) using a tablet
- Risk assess and control the risks
- Use results to justify refuting or supporting a claim
