Disección de un Cerebro de Oveja

Al disectar un cerebro de oveja los estudiantes logran apreciar la complejidad de un cerebro. Los estudiantes realizan observaciones, aprendiendo acerca de la estructura y función de las áreas del cerebro, de la sustancia blanca y gris.

Open Inquiry using C. elegans

C. elegans is a free-living nematode. It is small—growing to about 1 mm in length—and lives in the soil (especially in rotting vegetation) where it survives by feeding on microbes such as bacteria.

In this lesson, students pose questions, design, conduct, and analyze a controlled experiment testing different behavioral stimuli of the worm C. elegans.


To be healthy, the human body must maintain equilibrium in its many systems — e.g., levels of water and minerals in the blood, blood pressure, absorption of nutrients and removal of waste products from cells. This is called homeostasis.

The body's heat regulation system is another example of a homeostatic system. As the internal temperature rises, the body sweats to cool off. Alternatively, when the body gets very cold, it starts to shiver to generate some heat. The goal in both cases is to bring the internal temperature back to 98.6 degrees F.

Try Angle

Students use an Etch A Sketch® device to trace a triangle shape, erase it, and repeat the trace a couple of times to test the effect that repetition has on the ease or difficulty of a task.

This Is Cool

A student tests heat/cold sensitivity by dipping a finger into containers of cold and warm water. Human sensory systems are highly adaptable. This activity demonstrates the process of sensory adaptation. Students investigate how the perception of temperature changes under three separate conditions. They also relate the process of sensory adaptation to homeostasis.

Tell Me About It

Two partners face each other; one builds a structure that the other cannot see. The builder describes the structure and the partner tries to build the same structure following only verbal instructions.

Once the partner's structure has been built, both builders discuss what parts of the brain may have been involved and consider the difficulty or ease of this activity. Key concepts include mirror neurons and memory.

Memory Box

Two students work together - one opens a box and looks at the contents for 10 seconds then, with the box closed, tells the other student all the items remembered. The task is repeated with a second box. Will more items be remembered the second time?
