Soap Film on a Can
Source Institutions
The beautiful iridescent colors of a bubble in a can! With this Exploratorium Science Snack, create beautiful soap films on the open end of a can to see beautiful rainbows of color.

Ruminating on the Digestive System
Source Institutions
In this activity, learners will review the functions of basic digestive organs, understand how diet affects digestion, understand how digestive tracks may differ, and then step outside to compare the

Does Sunscreen Protect My DNA?
Source Institutions
In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.

Rock Pioneers
Source Institutions
In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.

See It to Believe It: Visual Discrimination
Source Institutions
In this activity (12th on the page), learners investigate their ability to discriminate (see) different colors.

Dark Adaptation
Source Institutions
In this activity (6th on the page), learners investigate how photoreceptors in the eye (rods and cones) "adapt" to low light conditions.

Finding a Gene on the Chromosome Map
Source Institutions
In this activity, learners use pedigree and jigsaw puzzles to explore how scientists use genetic information from a family to identify a gene associated with a genetic disorder.

Measuring Your Blind Spot
Source Institutions
In this activity, learners calculate the width (horizontal diameter) of the blind spot on their retina. Learners make a blind spot tester using a piece of notebook paper.

Attention!
Source Institutions
In this outdoor art/environmental activity, learners create designs that will attract attention to animals and plants in particular habitats, and then test whether their designs attracted the "right"

Mystery Noises
Source Institutions
In this game (4th activity on the page) about hearing, learners test their ability to identify various sounds without looking.

Beam Me Up!
Source Institutions
This is a quick activity (on page 2 of the PDF under Stained Glass Activity) about the "Tyndall effect," the scattering of visible light when it hits very small dispersed particles.

Expose Your Nose
Source Institutions
In this simple exploratory activity (1st activity on the page), blindfolded learners try to identify mystery items by smell.

Our Chemical Senses: Olfaction
Source Institutions
In this activity, learners investigate the olfactory system by conducting several experiments.

How Loud is Too Loud
Source Institutions
In this activity (described on pages 39-42 of PDF), learners make a paper wheel (on pages 57-60 of PDF) that shows them the relative loudness of different sounds.

Cardiac Hill
Source Institutions
In this outdoor activity linking human health to the environment, learners use their pulse rates as a measure of the effort expended in walking on different slopes.

Coral, Carbon Dioxide and Calcification
Source Institutions
In this group activity, learners act out key stages of the "ocean carbon cycle" (also known as the "carbonate buffer system") through motions, rearranging blocks and team tasks.

Crunch Time
Source Institutions
In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.

Fish Features and Habitats
Source Institutions
In this activity, learners observe live fish in tanks to consider how their body structures are related to their behaviors and habitats.

Depth Spinner
Source Institutions
Experience a spinning spiral...you won't be hypnotized, but you'll see what happens when you look away. It's like getting off a merry-go-round and everything keeps moving.
