The Mystery Lab

What does this filter include?

Students have to use experimentation to answer a simple question - which material is a sample made of, what chemical is being used, or what electric component is in this circuit? This makes the aims instantly clear in the students mind, and by solving the mystery they inadvertently learn the key concepts!

Here are some examples of the Mystery Filter being applied:

Notes and limitations of applying this filter

This Filter is great for material/substance characterisation labs, but can also be used in a "What's in the box?" scenario where you shroud a component (electrical component or a fluids device) from view and students can measure outputs from a range of inputs to identify what's inside.
