Earth's Systems (ESS2)

Step by Step Weather Observations

As a citizen scientist, you can take your own air temperatures with an outdoor thermometer and compare your readings to the official ones from the National Weather Service. It is important that you follow the correct procedures, however, for placing your thermometer. This activity will help you to do that, as well as find out what the normal yearly average temperature is for each day.

Take the Pulse of Your Classroom

The following activity can leverage SeisMac technology to help students understand how a seismometer records ground motions.

The EarthTrek Gravestone Project

The Gravestone Project, part of the global citizen science program called EarthTrek (www.goearthtrek.com), is seeking volunteers to visit cemeteries around the world and collect scientific data on how marble gravestones are weathering.

The Great Ocean Conveyor

Learn about ocean currents and systems in this activity from NOAA.

The Mountain Blows its Top

Students will observe fault movements on a model of the earth's surface.

Third From the Sun

In 1972, NASA launched a special satellite called Landsat that contained a new camera designed to take pictures of the Earth. Why was this satellite so incredible? Well, it could take a series of pictures of almost the entire Earth over and over again, season after season, month after month, year after year. You will be seeing Landsat images in this activity and learn how to interpret them.

Tropical Atlantic Aerosols

In this 50-minute activity, you can use NASA satellite data to find out where there are the greatest concentrations of aerosols over the course of a year in the tropical Atlantic region, and where these aerosols come from.

Watch Out for Landslides

Landslides not only are dangerous — causing on average more than 25 deaths and over $1 billion in damages a year — but are also widespread, occurring in all 50 states. Compounding the hazards, these natural disasters often occur along with other similar natural phenomena, such as floods or earthquakes. To minimize risk, the slope of land and materials underground must be considered when planning how to build in a community. Altering the slope of land, or even the amount of vegetation on a slope, can have dangerous consequences.

Water: A Never-ending Story

Water on earth is used over and over. The water cycle, the continuous movement of water from ocean to air and land then back to the ocean in a cyclic pattern, is a central concept in meteorology.

What-a-Cycle

Water moves from Earth’s surface to the atmosphere and then returns to the surface. This process is nearly always depicted in water cycle diagrams by arrows drawn in a circular direction.

However, the actual path water may take in its cycle is far more complicated. In this activity, you will discover multiple cycles by acting as water molecules and traveling through parts of the overall water cycle. In the end, your water cycle will look nothing like the conceptual model but will represent a more realistic cycle.
