Exploring Conductors and Insulators in Science

Andrew and Kate from the Connecticut Science Center explore the concepts of conductors and insulators using two seemingly identical blocks. They conduct an experiment with ice cubes to demonstrate how different materials affect heat transfer. The metal block, a conductor, melts the ice faster than the plastic block, an insulator. Viewers are encouraged to try similar experiments at home using everyday materials and to share their findings with the science center.

What initial observations did Andrew make about the two black squares?

• They are different sizes.

• They are different colors.

• They are the same color and size.

• One is thicker than the other.
