How far can you see out of the corner of your eye? Grab a partner and find out from the Exploratorium Science Snack.

In this activity, learners work in groups to match craft sticks that represent chromosomes. Learners must define critical attributes of their chromosomes as they look for matching chromosomes.

Learners add drops of alginate solution to a solution of calcium chloride. The alginate does not mix with the calcium chloride, but forms soft gel beads.

In this outdoor activity, learners first explore lizard feeding behavior by creating a "lizard rig" to dangle different objects in front of live lizards and see which objects the lizards try to bite.

In this activity, learners make critters out of recyclables and apply the rules of mathematics to solve genetics problems.

In this activity, learners will investigate and compare the root systems of plants. Explore how weed and edible plant roots differ, and take a closer look inside with the careful use of a knife!

In this data analysis and environmental science activity, learners examine the effects of pollution on amphipods using data from the Chesapeake Ecotox Research Program.

In this activity, learners make balloon models of disease-causing bacteria.

This is an activity where learners will discover what types and how many insects live in their own backyard.

In this activity, learners investigate the food, water, and space needs of common livestock animals.

In this activity, learners explore a bucket of sand and beach objects.

Learners make self-assembled polymer spheres as a model for the lipid nanoparticles found in COVID-19 mRNA vaccines.

In this lab (Activity #1 on page), learners compare bacteria growth on two petri dishes containing nutrient agar: one that has been touched by a finger washed only with water and one that has been tou

In this activity, learners construct a coastal landmass from sand and add features such as tidal creeks and barrier islands.

In this quick and simple activity about reflexes (third activity on the page), learners conduct a simple test to explore the knee jerk reflex, typically conducted at the doctor's office.

What is the optimal environment for hatching brine shrimp? Using a scaffold, learners design and conduct experiments testing the effect of a single abiotic factor on brine shrimp cyst hatch rate.

In this activity (2nd activity on the page), learners explore the sensitivity of their sense of touch.

In this quick and simple activity about reflexes (at the top of the webpage), learners conduct a simple test to explore pupillary response.

In this activity (8th activity on the page) about the sense of touch, learners make their own set of Braille letters. Learners use glue to make raised dots on a Braille Alphabet Sheet.

In this activity, learners use earthworms as "unknown creatures" from the South American jungle to find out how animals use senses.
