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.
Hold a Hill
Source Institutions
In this outdoor activity, learners investigate the relationship between the slope of a trail and soil erosion.
Quadraphonic Wind
Source Institutions
In this activity, learners discover how the extent of various wind speeds changes in each of the four quadrants around a hurricane.
A Cubic Foot Per Second
Source Institutions
In this activity, learners measure and calculate the amount of cubic feet various containers contain. Next, learners investigate cubic feet per second (cps), by carrying jugs in one second.
Whose Fault Is It?
Source Institutions
In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.
Arctic Sea Ice
Source Institutions
In this activity, learners explore how the area of Arctic sea ice has changed over recent years. First, learners graph the area of Arctic sea ice over time from 1979 to 2007.
Let's Count Humpback Whales: Environmental Effects on Population
Source Institutions
In this activity, learners use whale count data from the Hawaiian Islands Humpback Whale National Marine Sanctuary to compare whale counts in relation to environmental factors.
The Scoop on Scallops
Source Institutions
In this data analysis activity, learners quantify the abundance and distribution of sea scallops in and adjacent to the Mid-Atlantic closed areas.
Sea State: Forecast Conditions at Sea
Source Institutions
In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.
Percentage of Oxygen in the Air
Source Institutions
In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.
The Shadow Knows II
Source Institutions
In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.
Prehistoric Climate Change
Source Institutions
In this online interactive, learners use fossils to infer temperatures 55 million years ago, at the sites where the fossils were found.
For the Birds: Environmental Effects on Population
Source Institutions
In this activity, learners will investigate how shorebirds and seabirds are extremely vulnerable to changes in their environment, whether human-induced or otherwise.
Chilean Sea Bass: Off the Menu
Source Institutions
In this data analysis activity, learners use data collected by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) to study Chilean sea bass populations.
Inverted Foucault Pendulum
Source Institutions
In this demonstration, learners explore a variation of a Foucault pendulum, but upside down.
Earth Walk
Source Institutions
In this hands-on and feet-on excursion, learners take a science walk to visualize the planet's immense size and numerous structures, without the usual scale and ratio dimensions found in most textbook
Mosquito Life Cycle
Source Institutions
In this activity, learners build a plastic emergence chamber (or use purchased "mini mosquito breeder") to observe and analyze the mosquito life cycle.
Globe at Night
Source Institutions
In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.
Fish Eyes: More than Meets the Eye
Source Institutions
In this data collection and analysis activity, learners evaluate fish physiology and ecology using vision research data from Dr.
Determining the Amount of Transpiration from a Schoolyard Tree
Source Institutions
In this activity, learners calculate the number of milliliters of water a nearby tree transpires per day.
