Intermolecular Forces

Bubble, Bubble, Toil and Trouble

In this Activity, students first create a standard bubble solution by mixing water with liquid dishwashing detergent. They then add different substances to samples of the detergent solution. The solutions are compared to see which produces the longest-lasting bubbles. The Activity is a fun way to introduce the concepts of surface tension, intermolecular forces, and the use of surfactants.

New Paper from Newspaper

In this Activity, students examine a piece of newsprint and recycle the paper to make a new sheet of paper that can be compared to other types of paper. They then use this experience, and information from Internet sites, to create a paper work of art. The Activity could be used as a cross-curricular topic in an art class.
