This activity (on page 2) explores how sensing is part of robotics. Learners try tying their shoes with different constraints.

In this outdoor archaeology activity, learners use mathematical skills and scientific inquiry to generate and process information from their own excavation site.

In this activity (23rd on the page), learners conduct an experiment to examine memory and learning.

In this genetics activity, learners extract DNA from an onion, using detergent solution, a food processor, and rubbing alcohol. They will also discuss genetic engineering of plants.

In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

Using pipe cleaners, straws, and beads, learners explore the building blocks of life by creating their own model of DNA.

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

In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

In this activity (25th on the page) about learning and memory, learners explore a training method that animal trainers employ called "shaping." Working in pairs, learners will attempt to "shape" each

In this optics activity, learners discover basic lens-making techniques by using a tennis ball to make a lens out of ice.

In this activity (on page 134 of the PDF), learners explore reaction time.

In this yummy biology activity (page 3 of the PDF), learners participate in a demonstration of natural selection.

Millions of organisms can live in and around a body of water.

This is an activity about lung capacity. Learners will measure their own lung capacity using a homemade spirometer.

In this outdoor activity, learners review the parts of the synapse and their functions by playing a game.

This is an activity where learners will compare the different metamorphosis stages of amphibians.

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.

This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells. It includes an optional test for the presence of DNA.

In this activity, "write" a secret message in genetic code as beads on a string.

The purpose of this plant biotechnology activity is to demonstrate the effect of changes in the environment on the growth and fertility of landscape grasses and crop grasses such as wheat and rice.
