Dust Catchers
Source Institutions
In this activity related to indoor air pollution, learners build take-home dust catchers with wax paper and petroleum jelly.
Skin Deep
Source Institutions
In this activity, learners explore how to protect their skin while applying pesticides to plants.
Clam Hooping
Source Institutions
In this two-part outdoor activity, learners conduct a population census of squirting clams on a beach or mudflat, and investigate the clams' natural history.
Pollinator Play
Source Institutions
In this activity, learners will build a bee hotel for pollinators. Learners will explore building and ecology through this activity.
Crime Scene Investigation (CSI) with Powdery Mildew Fungi
Source Institutions
This exercise can be used to stimulate the investigative nature of learners as they use forensic plant pathology techniques to prove the learners' innocence in a mock murder investigation.
OBIS Oil Spill
Source Institutions
In this outdoor activity, learners simulate an oil spill using popcorn (both oil and popcorn float on water), and estimate the spill's impact on the environment.
Cool Tool
Source Institutions
In this activity (on pages 10-17), learners discover how scientists study biodiversity and the health of the environment based on inspection of small areas—a process known as sampling.
Shoebox Dinosaur Dig Site
Source Institutions
In this activity, (on page 6 of the PDF under SciGirls Activity: Dinosaurs) learners participate in a hands-on fossil excavation.
How Greenhouse Gases Absorb Heat
Source Institutions
Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.
Malformed Frogs
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Malformed Frogs) is a full inquiry investigation into using indicator species to assess the health of an environment.
Scavenger Hunt: A Group Collection
Source Institutions
In this activity, learners are divided into teams.
Great Steamboat Race
Source Institutions
In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.
Cool It
Source Institutions

Off Base
Source Institutions
In this activity, learners explore the factors that tend to resist changes in pH of the ocean and why the ocean is becoming more acidic.
Wintergreen
Source Institutions
In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.
Microbes are Everywhere
Source Institutions
In this four-day activity, learners grow bacteria and/or fungi from a variety of locations and compare the results.
Blowin' in the Wind
Source Institutions
In this environmental engineering activity, learners build windmills using everyday items. The first challenge is to build windmills that spin when placed in front of a fan.
Mystery of the Disappearing Cottonwoods
Source Institutions
Learners will explore the scientific mystery behind a disappearing group of trees by examining data and attempting to explain the decline.
