Water Cycle in a Bag
Source Institutions
In this activity, learners create a biosphere in a baggie.
Hand Battery
Source Institutions
In this activity about chemistry and electricity, learners form a battery by placing their hands onto plates of different metals.
Sawing Away
Source Institutions
In this outdoor activity, learners saw sections from fallen trees, then count tree rings and look closely at patterns of tree growth.
Colored Shadows
Source Institutions
In this optics activity, learners discover that not all shadows are black. Learners explore human color perception by using colored lights to make additive color mixtures.
Otter Smorgasbord
Source Institutions
In this graphing activity (on pages 33-40), learners investigate how much and what kinds of food sea otter pups eat during their first year of life.
Exploring Size: Scented Solutions
Source Institutions
This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).
Water Treatment
Source Institutions
Water treatment on a large scale enables the supply of clean drinking water to communities.
Freshwater Ecosystems
Source Institutions
In this activity, learners create a freshwater ecosystem in a large plastic bottle. Learners cut and prepare bottles, then fill with water, aquatic plants, snails and fish.
Sand Dunes
Source Institutions
This outdoor activity (on page 2 of the PDF under SciGirls Activity: Sand Dunes) is a full inquiry investigation into how the amount of moisture in a sand dune relates to the number of plants growing
Biotechnology Through Time
Source Institutions
In this activity, learners investigate the history and development of agricultural biotechnology.
Global Climate Change and Sea Level Rise
Source Institutions
In this activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.
Comparing Sizes of Microorganisms
Source Institutions
In this activity related to microbes, learners create scale models of microorganisms and compare relative sizes of common bacteria, viruses, fungi and protozoa using metric measures: meters, centimete
Aerial Imagery
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Earthquakes) is a full inquiry investigation into aerial imagery.
Blue Sky
Source Institutions
In this optics activity, learners explore why the sky is blue and the sunset is red, using a simple setup comprising a transparent plastic box, water, and powdered milk.
Junk-in-the-Box
Source Institutions
In this outdoor activity, learners explore how a surprising number of animals use human-made litter, such as cans and crumpled paper, to find food and shelter in their environment.
Fruity-Glows: Pictures of Health on a Microarray Canvas
Source Institutions
In this activity (page 12), learners apply the concepts of pixilation and pointillism to the world of biomedical science.
Leapin' Lizards
Source Institutions
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.
Hatch-a-Cyst
Source Institutions
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.
The Variety and Roles of Microbes
Source Institutions
In this activity, learners use sets of cards to assign microorganisms to different groups.
Hike the Habitat: Field Trip in Canyonlands National Park, Utah
Source Institutions
This detailed lesson plan for a field trip to Canyonlands National Park in Utah (page 32 of pdf) teaches students about the habitat of bighorn sheep.
