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 II
Source Institutions
In this activity, learners discuss the different salinities of oceans, rivers and estuaries.
Toxic Popcorn Design Challenge
Source Institutions
In this activity, learners explore the engineering design process (EDP)—the process engineers use to solve design challenges.
Future Moon: The Footsteps of Explorers
Source Institutions
In this activity, learners drop impactors onto layers of graham crackers!
Evolutionstechnik or Selection and Variation in the Egyptian Origami Bird (Avis papyrus)
Source Institutions
In order to examine the random nature of mutations and natural selection, learners "breed" clutches of Egyptian Origami Birds (Avis papyrus) using random number generators (dice and coins) to mutate s
Pom Pom Potential
Source Institutions
In this kinesthetic activity, learners move pom-pom "ions" across a membrane to simulate how an action potential is propagated along an axon.
Clipbirds
Source Institutions
In this simulation of natural selection, learners use binder clips in three different sizes to represent the diversity of beak sizes in a bird population.
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.
Population Game
Source Institutions
In this outdoor game, learners simulate a herd of deer trying to survive in an area called the "home range." Learners explore the concept of "carrying capacity"—what size population of an organism can
Wind Tunnel
Source Institutions
Scientists use enormous wind tunnels to test the design of planes, helicopters, even the Space Shuttle.
Generations of Traits
Source Institutions
In this hands-on activity, learners track and record the passage of colored "pompom traits" through three generations of gingerbread people.
Pick the Risk: The Polygenic Pedigree Challenge
Source Institutions
In this activity, learners are challenged to track and record the passage of colored pom poms (representing genes) through generations of a family using a pedigree.
Can Nutrients in Water Cause Harm?
Source Institutions
In this water pollution activity, learners create pond water cultures and investigate the effects of adding chemicals or natural nutrients.
Chocolate Lava
Source Institutions
In this yummy earth science activity (page 5 of the PDF), learners use fudge to learn about different kinds of lava.
Survival of the Fittest: Battling Beetles
Source Institutions
This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection through data collection and pattern recognition.
The Water Cycle
Source Institutions
Did you know that the water we use today is the same water found on Earth millions of years ago? The Earth constantly uses and recycles water in a process called the water cycle.
Radar Mapping: What's in the Box?
Source Institutions
In this activity, learners mimic remote sensing. Learners use a stick to measure the distance to a "planet surface" they cannot see, and create their own map of the landscape.
Scram or Freeze
Source Institutions
In this outdoor activity and animal-role-play game, learners discover and uncover the hidden world of "cryptozoa"—organisms such as spiders, salamanders and slugs that live under objects, like rocks a
Fuzzy Worms
Source Institutions
In this activity, learners explore the concepts of natural selection and observable traits in a game that can be played at home.
Water Treatment
Source Institutions
Water treatment on a large scale enables the supply of clean drinking water to communities.
