How can we slow down the transfer of heat energy? Our class tested various insulators and wrapped these materials around a plastic bottle containing warm water. These materials included aluminum foil, plastic wrap, bubble wrap, polyester batting, fleece, and a carpeting pad. The insulated bottles were places in gallon ziplock bags and then set in a tub of ice cold water. Temperature readings were taken at the start and after five, then ten minutes. Findings were compared and discussed.

Many adjustments were made to the boats to help them move faster and straighter. After the excitement and clean-up, students reflected on the energy transfers that took place and what steps they took to improve their boats. This week, our class has explored what energy is, the many forms in which it can be found, and the transfers energy can take from one to another. A Plasma 360 ball allowed for scientific thinking and wondering. Students tested out various toys in small groups at stations to study the toys' energy transfers. Next week, they will build boats that use various forms and sources of energy using various supplies such as rubber bands, balloons, baking soda and vinegar. |
