In this activity, students learn to interpret current weather maps. They will observe weather map loop animations on the internet, learn the concept of Zulu time (Universal Time Coordinated, UTC) and visualize the movement of fronts and air masses. They will then analyze a specific weather station model, generate a meteogram from their observations, and answer a set of questions about their observations.

Students learn how Newton's Law of Gravitation can be used to determine the mass of the Earth. By calculating mass and volume, they can then determine the Earth's density, and compare that result with the densities of other solar system bodies. Knowledge of Earth's density can also provide information about the planet's interior.

In this exercise, students investigate long-term weather variables such as temperature and humidity to determine their affect on the climate of a particular region. They will choose two cities, use an online resource to obtain geographic and climatic information for each, and use a spreadsheet program to produce graphs that compare data for the two cities.

The activity describes Eratosthenes' experiments which determined that the Earth is spherical, rather than flat. Students reproduce Eratosthenes' methods using a slice of pizza to calculate the circumference of the entire pie.

The purpose of this resource is to introduce students to the concept that sometimes there is no one "right" answer to a question or measurement. Students learn to be careful when searching for a right answer to questions such as 'What time is it?' by comparing multiple measurements of the time of day. Students gain an intuitive understanding of the characteristics of imperfect measurements. Using different clocks, students simultaneously record the displayed times. The resulting time measurements are converted from minutes and seconds to seconds. These measurements are plotted to illustrate the mathematical techniques of averages and deviations from an average.

This lab activity uses the internal structure of newspaper (its fibers) to explore the ways in which the internal structure of a material can affect how it behaves. The findings can be related to the physical and chemical properties of minerals, which are influenced by their own internal molecular structures.
In this activity, students investigate the mass, pressure, and temperature of air. …
In this activity, students investigate the mass, pressure, and temperature of air. They will measure and record the mass and temperature of a bottle of air as they increase its pressure by pumping in more air, record their observations, and answer some questions about what they have seen.

In this activity, students use METeorological Aerodome Reports (METARs) to view changes in temperature, dew point, air pressure, sky condition, wind, and visibility at White Plains, New York. After studying the reports, they answer a series of questions related to radiation and insolation, radiative balance, and meteorological processes.
