In this activity, students investigate how pressure affects the temperature of air and how this relates to the formation of clouds in the troposphere. They will form a cloud in a bottle, find the dew point and relative humidity of air at different places in the school and use a chart to estimate how high that air would have to rise to form a cloud.

This video segment from NatureScene features the area of the Congaree Swamp where the high ground and the flood plain meet. Learn how a few feet of difference in elevation on a floodplain can yield drastic changes in what youŰ__Ű__Çll find living there.

In this activity, students use a National Weather Service flood forecast, USGS gauging data, and other reports to estimate the maximum storm discharge from the New River and Wolf Creek, two streams in the Southeast U.S. which experienced flooding in November 2003. Topographic and urban maps are used to predict where flooding would occur and to evaluate strategies for reducing flood risk for the residents of the region.

In this adaptation of a video that high school students created in collaboration with the Environmental Justice League of Rhode Island, learn what's whack about our current food systems and the many actions individuals can take to address these issues.

SYNOPSIS: This lesson explores the complexities of food waste and its connection to climate change.
SCIENTIST NOTES: This lesson illustrates the concept of food waste and food loss and provides initiatives to reduce food waste. This will not only help in improving food security but is a good alternative to drawdown greenhouse gas emissions from food waste. All materials have been fact-checked, and the lesson is credible for teaching.
POSITIVES: -This lesson includes a diverse set of perspectives, communities, and solutions. -Students are able to learn about the complexity of food waste from different contexts.
ADDITIONAL PREREQUISITES: -Students are likely to have different perspectives and emotions regarding food waste. It can be an overwhelming experience to learn about the severity of this problem. This lesson embeds questions to give students time and space to process these emotions and inequities. -The Big Waste video contains some statistics from 2012-2013, so some data may be outdated and obsolete.
DIFFERENTIATION: -Seeing the severity and inequities of food waste might cause feelings of anxiety, sadness, anger, despair, or surprise in some students. It is recommended for teachers to remind them that those feelings are normal and natural. Sharing those feelings with the class can help support students’ social-emotional learning. It is recommended to encourage students to share their honest reactions. -This exploration and these discussions might naturally lead into the “What can we do about it?” discussion.

About 4.6 billion years ago, a cloud of interstellar dust, ice crystals, and gas collapsed to form a rapidly rotating disk with a young sun at its center: our solar system. This comic strip, a supplement to the Hall of Meteorites Educator's Guide, explains the processes that led to the creation of the planets and the asteroid belt.

The lesson will first explore the concept of current in electrical circuits. Current will be defined as the flow of electrons. Photovoltaic (PV) cell properties will then be introduced. Generally constructed of silicon, photovoltaic cells contain a large number of electrons BUT they can be thought of as "frozen" in their natural state. A source of energy is required to "free" these electrons if we wish to create current. Light from the sun provides this energy. This will lead to the principle of "Conservation of Energy." Finally, with a basic understanding of the circuits through Ohm's law, students will see how the energy from the sun can be used to power everyday items, including vehicles. This lesson utilizes the engineering design activity of building a solar car to help students learn these concepts.

In this two-part example, students are given clues about properties about the terrestrial and Jovian planets respectively and asked to match up the planet with the correct equatorial radius, mean orbital velocity, and period of rotation.

In this Digital Universe activity, students learn firsthand about estimation strategies and observational bias. They estimate how common several celestial objects are based on their location and make inferences about larger population patterns throughout the galaxy. The printable PDF activity includes illustrated step-by-step instructions for the following hands-on and computer-assisted activities: Introduction to Celestial Objects, Broad Distribution of Objects in the Galaxy and Making Galactic Estimates

This video segment adapted from NOVA shows how Galileo, using his newly developed refracting telescope, observed four of Jupiter's moons, the first astronomical bodies to be discovered since ancient times.

In the early 1600s, most people believed that the Sun revolved around a stationary Earth. This video segment adapted from NOVA tells how Galileo proved that the Sun, not Earth, is at the center of our universe.

This video from NASA describes the GLAST satellite, which is equipped with a gamma-ray telescope, and shares some background about the kinds of extreme universal phenomena indicated by the presence of gamma rays.

The Gamma-ray Burst Skymap website automatically updates for each gamma-ray burst as it occurs, whether detected by Swift or other orbiting satellites. For each burst, the location on the sky, star map, constellation and detecting mission are generated automatically. It is then quickly updated by hand to include a written description of the burst properties and scientific significance, as observations continue. Note: In order to view the content of the website, users need to download and install Silverlight on their computers.

Students learn how a telescope's aperture determines how much light it can gather in this Moveable Museum unit. It has three procedures, one of which is optional. The four-page PDF guide includes suggested general background readings for educators, activity notes, step-by-step directions, and information about where to obtain supplies. In this activity, the light collector is not a lens or a mirror, but a hole in a cardboard box. Light enters through the hole and lights up the box. Users can change the size of the hole and see how the amount of light entering the box changes. The results show why increasing the aperture of a telescope increases the amount of light it can collect.
