At first glance, Katena might look like an ordinary inflatable with an unusually complex and oversized structure. But when they walk inside, visitors soon realize this is an entirely different experience. They enter a world apart, a world of interconnecting tunnels and domes saturated with light and color, called a luminarium. This video will take your students on a virtual tour of one luminarium that was featured at the Cincinnati BLINK festival. They will learn how the design team of Architects of Air blends geometry, art, and architecture to create a pneumatic, or air-filled, structure in which form must follow function.

In this feature, adapted from Interactive NOVA: "Earth," students explore the relationship between oxygen concentration and the well-being of various organisms by simulating a change in oxygen levels and observing what happens.

In this interactive activity from ChemThink, take a closer look at atomic structure, properties, and behaviors.

This video segment adapted from A Science Odyssey takes a look at the scale of the atom and the tremendous amount of space between the electrons and the nucleus. If all this empty space exists in matter, how can any substance be solid?

Novel representations and diverse perspectives can reveal new insights into complex systems, and can support rich understandings of the world. In this activity, students will identify and analyze the choices artists and scientists make when creating representations of living or non-living natural objects. This process will help students recognize the potential and place for their own articulation of how the world works. After drawing from nature, students will reflect on the process of representing information, then compare their drawings with that of a 16th-century artist. Students will consider what is included and what is excluded, and hypothesize about larger contexts and systems.
