Another one of Dr.O.’s very hands-on laboratory experiments that will engage students and incite their curiosity, while they learn several chemistry concepts. These concepts include: single-replacement reactions, making and documenting observations, balancing chemical equations, chemical and physical properties, and much more. Students will be intrigued as aluminum foil appears to vanish before their eyes, yet, they will soon deduce that it is nothing more than a reduction-oxidation (REDOX) reaction.
I have used this laboratory-experiment assessment with middle school students, as well as high school students. It can be used in a high school chemistry class or a lower level physical science class. I used it earlier this year with my 8th graders who enjoyed the experience, while reviewing key concepts they had already been taught in class. This lab experiment is also great to use as a teacher demonstration, while students write down their observations on the sheets provided.
