In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about

In this two-part activity, learners investigate buoyancy, density and surface area as well as biodiversity and the relationship between the structure and function of organisms.

In this activity, learners investigate color vision as well as plan and conduct their own experiments.

In this activity, learners cut, fold, and paste paper representing biomolecules to create a three-dimensional cell membrane with embedded proteins.

Make a big canvas of iridescent color with pvc pipe! In this Exploratorium Science Snack, you'll need to cut and assemble some PVC pipe, but the pay-off, the soap-bubble canvas, is big.

In this activity, learners create a model of a neuron by using colored clay or play dough. Learners use diagrams to build the model and then label the parts on a piece of paper.

In this biology activity (page 5 of the PDF), learners use yarn and sticky labels to build a model of a DNA strand. They discover that DNA is very long, very skinny, and packs well into cells.

The Ancient Egyptians used a naturally-occurring salt from the banks of the Nile River, called natron, to mummify their dead.

As a long-term project, you can rear monarch butterflies at home or in a classroom.

In this activity on page 8 of the PDF, learners make a slimy substance very similar to mucus, and sprinkle it with glitter to imitate the way that allergens are trapped.

Somatic Cell Nuclear Transfer (SCNT) is a cloning method that involves transferring a nucleus from a somatic cell of the individual to be cloned to an enucleated egg.

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

This activity provides an opportunity for learners to observe and examine how carbon dioxide, water, and light produce glucose/starch through a process called photosynthesis.
