A portable science exhibit packed into a board book exploring topics in neuroscience and biology.

"The Visual System" invites learners to put "lesions" along the visual system and hold up the book to their eyes to experience an altered visual system.
When parts of the optic nerve or optic tract are destroyed, our vision is affected in predictable ways. Depending on where damage occurs on the visual system, it can cause blindness to a single eye or to a "visual field" that is created by both eyes.

"Membrane Transport" invites learners to put proteins on the membrane to observe how the LED "particles" move across.
Our cells need to control their contents by allowing substances in and taking substances out. When substances are not able to pass through the membrane on their own, they need the assistance of facilitated diffusion or active transport. Facilitated diffusion doesn't require energy but only allows substances to "even out", whereas active diffusion can move substances anywhere but requires energy every time.
