By experimenting with materials found around the house, students learn that some substances react differently when they are mixed. This workshop examines the three states of matter, solid, liquid and gas. Students can learn about how materials change from a liquid to a solid form by making ice cream and candy. In the ice cream lesson students use liquid nitrogen to mix the ingredients. Graduate student Josh Pomeroy developed a lab called Edible Glass .
Students make candy to understand molecular bonding of materials like glass.
