Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.

In this hands-on activity (on page 2 of the PDF), learners experiment with lemon juice and paper to create a message that can only be revealed using chemistry.

In this activity, learners write a secret message in "invisible ink" and then use chemistry to view the writing.

In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.

In this activity about combustion and energy, learners observe a burning candle in a sealed jar and the burning of white sugar.
