Why Lesson Planet?
Glass comes into focus through these three activities. In the first, junior scientists actually make Borax glass. This activity would be useful when examining physical and chemical changes. The second activity involves glass blowing a tube into a bud vase. Use this as an enrichment activity when considering phase changes. Finally, the electrical conductivity of glass is measured and recorded. Use this with physics classes during an electricity unit. Mini videos, background information, and a teacher's guide are included for your support.
