In this activity (on page 2 of PDF), learners mix oil and water. Then, they add soap and observe what changes! The activity demonstrates how oil and water don't mix, except when soap is added.

In this arts and crafts activity about animals and animal characteristics, learners will design animal hats and role-play as animals.

In this activity, learners use their imaginations and experiment with different materials to create bug hats.

In this activity (on pages 41-47 of PDF), learners explore tesselating geometric patterns (repeated shapes, similar to the art of M.C. Escher).

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

This is an activity in which learners create magic wands from a variety of materials making their choices by considering what kind of magic they want to make.

This activity is on page 3 (continued on page 2) of the pdf, part of the Simple Machines Discovery Box. In this fun activity, learners "create" a complex machine by simulating the parts in action.

In this tabletop activity (on pages 32-40), learners make Möbius strips -- 3D surfaces with only one side.

In this activity (on page 2 of the PDF), learners use art supplies to build models of insects, both real or imagined.

In this activity about dinosaurs and survival, learners use scrap materials to create a miniature dinosaur habitat that includes a food source, water source, and shelter.
