Mercury in the Environment
Source Institutions
In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.
Water Body Salinities I
Source Institutions
In this activity, learners investigate the different salinity levels of oceans, rivers and estuaries.
Water Body Salinities II
Source Institutions
In this activity, learners discuss the different salinities of oceans, rivers and estuaries.
Habitat Adaptation Matchup
Source Institutions
In this activity, learners work in small groups to match various marine animals with their different environments.
Bone Identification
Source Institutions
This activity (page 3 of the PDF under SciGirls Activity: Dinosaurs) is a full inquiry investigation into fossil hunting and identification.
Measuring Biodiversity
Source Institutions
Learners use a variety of beans to represent a variety of species, and scatter these beans over a large piece of paper representing the environment.
Biodomes Engineering Design Project
In this design-based activity, learners explore environments, ecosystems, energy flow and organism interactions by creating a model biodome. Learners become engineers who create model ecosystems.
Life in a Nutshell
Source Institutions
In this multi-faceted game (on pages 25-35), learners recreate what happens to creatures in the Brazilian rain forest as they grow from egg to adult—especially those that use fallen, empty Brazil nut
Water Quality and pH Levels in Aquatic Ecosystems
Source Institutions
In this fun and in depth hands-on experiment, learners test various liquid samples (distilled water, lemon juice, vinegar, and baking soda mixed with water) to determine their pH levels and identify e
What's in the Water?: Biotic and Abiotic Elements in Aquatic Ecosystems
Source Institutions
In this investigation learners explore the differences between, and interdependence of, living and nonliving elements in a water ecosystem.
Biological Succession in a Microecosystem
Source Institutions
This laboratory activity helps learners understand the concept of biological succession by simulating the process in a microenvironment with various protozoans.
Sustainable Fishing
Source Institutions
In this activity, learners use a model for how fishing affects marine life populations, and will construct explanations for one of the reasons why fish populations are declining.
Food Webs
Source Institutions
In this activity, learners construct possible food webs for six different ecosystems as they learn about the roles of different kinds of living organisms.
Human Impact on Estuaries: A Terrible Spill in Grand Bay
Source Institutions
In this activity, learners make a model of a pollution spill that occurred at Bangs Lake in Mississippi and measure water quality parameters in their model.
There’s Oil in My Eggs
Source Institutions
In this activity, learners investigate the impact of oil pollution on the environment and wildlife. Learners use hard-boiled eggs and feathers to understand the damage that oil spills can cause.
Give or Take?
Source Institutions
In this outdoor activity, learners work in pairs using their senses—especially touch—to learn more about individual trees.
Marine Ecosystems
Source Institutions
In the wild, small crustaceans known as brine shrimp live in marine habitats such as saltwater lakes.
Creating a Local Field Guide
Source Institutions
In this activity, learners survey living organisms near where they live or go to school, and create a local field guide.
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.
Sustainable Grazing
Source Institutions
In this activity, learners investigate the food, water, and space needs of common livestock animals.
