The Amazing Aerogel
Introducing ... the aerogel. The first of a two-installment series teaches young engineers about the properties and uses of aerogels. A PowerPoint presentation provides information about this unique material to help solidify the concept.
Curated OER
ENGINEERING TOOTHPASTE
Students make a class list of household products and discuss how many of these products are made through chemistry. They guess the ingredients in the products and imagine how toothpaste might be made. They make toothpaste.
