Dean Campbell uses demonstrations and props to illustrate concepts while teaching his collegiate Materials Chemistry course. Many of the examples described are also suitable for use in high school and collegiate General Chemistry courses.
This lab assessment is a wet lab that has students use lab skills to demonstrate their knowledge of polarity, Lewis structures, solubility, and intermolecular forces by justifying the polarity of given compounds.
What is some of the chemistry involved in the formation of ice clouds when boiling water is thrown into icy air?
This initial study outlines the effect on the colour of anthocyanin-containing solutions when mixed with caffeine. Given the diversity of anthocyanin structures available from other vegetables, fruits or flowers, there is great potential for series of open-ended experiments for students in classes or science clubs to investigate.
Discover the secrets behind flame-shaped highlighter markings that not only disappear and reappear but also glow and flicker under the influence of acids, bases, and UV lights.
Try out this though-provoking capstone demonstration for the Chemical Reactions unit!
Tissue paper can be folded and cut with chemistry-related patterns to make decorative paper banners that can be used as Mexican-themed decorations. Chemistry concept connections include lattice energy, bandgap energy, and ionic crystal fracture.
Igniting paper towels that have been soaked in concentrated potassium nitrate and allowed to dry yields a flame reminiscent of that produced by guncotton. Repeating this experiment with other metal nitrates produces flames with different colors, plus a few other chemical surprises! This series of experiments is fascinating and connects to a wide variety of chemical topics including combustion, redox reactions, chemical thermodynamics, and flame tests. You don't want to miss this one!
Regularly dimpled trays such as those used in food packaging can be used to represent layers of atoms in solid structures. For example, the square array of dimples in transparent plastic mini quiche trays can be used to depict layers within cubic or tetragonal unit cells. Multiple solid structures and ways to represent those structures are described.
