This fun hands-on astronomy activity lets learners explore models of the Milky Way and other galaxies to get a sense of relative distances to other galaxies.

In this activity (on pages 16-21), learners get a sense of geological time by understanding how big a million is.

In this activity, groups of four learners must complete a set of four manual tasks. The restrictions are that they must complete the tasks in a limited time while wearing garden or rubber gloves.

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

In this activity, learners solidify their conceptualization of cells by building a model of a cell in a ziplock bag.

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.
