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.
Dunking the Planets
Source Institutions
In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.
Exploring the Ocean with Robots
Source Institutions
In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.
Corals and Chemistry
Source Institutions
In this activity, learners investigate how increased carbon dioxide (CO2) emissions from the burning of fossil fuels is changing the acidity (pH) of the ocean and affecting coral reefs and other marin
What does Color have to do with Cooling?
Source Institutions
In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.
Glass and Mirrors: An Inside Look at Telescopes
Source Institutions
This hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.
Cook Up a Comet
Source Institutions
In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.
Inverted Foucault Pendulum
Source Institutions
In this demonstration, learners explore a variation of a Foucault pendulum, but upside down.
Acid Rain
Source Institutions
In this chemistry demonstration, acid rain is simulated in a petri dish.
Rock Bottoms
Source Institutions
Learners add acid rain (nitric acid) to two cups that represent lakes. One cup contains limestone gravel and the other contains granite gravel.
The Carbon Cycle and its Role in Climate Change: Activity 2
Source Institutions
In this activity (on page 7), learners explore the meaning of a "carbon sink." Using simple props, learners and/or an educator demonstrate how plants act as carbon sinks and how greenhouse gases cause
Differing Densities: Fresh and Salt Water
Source Institutions
In this activity, learners visualize the differences in water density and relate this to the potential consequences of increased glacial melting.
Burning Issues
Source Institutions
Learners use a candle to investigate the products of combustion. When a glass rod is held over a lit candle, the candle flame deposits carbon on the rod.
Canned Heat
Source Institutions
In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.
The Thousand-Yard Model
Source Institutions
This is a classic exercise for visualizing the scale of the Solar System.
Finding the Carbon in Sugar
Source Institutions
In this activity about combustion and energy, learners observe a burning candle in a sealed jar and the burning of white sugar.
What-a-cycle
Source Institutions
In this activity, learners act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.
Low-Tech Water Filter for High-Impact Clean
Source Institutions
In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.
Battling for Oxygen
Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.
Weathering and Erosion
Source Institutions
In this activity (page 13 of the PDF), learners discover how weathering and erosion change the Earth’s surface.
