The purpose of this activity is to construct a model that will provide students with a visual representation of parts per billion. Students work in teams to construct cubes of different volumes and to compare them to get a feel for parts per million by volume and parts per billion by volume. The intended outcome is that students gain a feeling for the small quantities of gases, such as ozone, present ... Full description.

This resource gives an impression of how immense our Universe is by starting with an image of the Earth and then zooming out to the furthest visible reaches of the Universe. Its goal is to show astronomical distances without scientific notation. Instead, it focuses on the large number of zeros that are in astronomical distances when we measure them with a familiar unit like the kilometer. The number ... Full description.
