This activity lets students measure distances in the classroom using parallax. The exercise can be done either at a high school level using trigonometric functions, or at a middle school level using simple arithmetic approximations to the trigonometric functions. A work sheet is provided for the middle-school-level activity.The resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

This classroom activity helps students understand the benefits and drawback of globes, Mercator maps, and polar map projections. After closely examining all three, students discuss how we represent a spherical object like the Earth on flat surface. The printable five-page handout includes a series of inquiry-based questions related to the representation of Antarctica on the three types of maps.

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.

In this animated video segment adapted from NASA, astronomer Doris Daou explains how the forces of speed and gravity keep the Moon in a constant orbit around Earth.

In this activity, students learn that the small droplet size of water the in the clouds and wind contribute to clouds remaining suspended in the sky. The demonstration requires a clear beaker, sand, and rocks. Several other activities are suggested.

In this week-long unit, students examine weather reports from all over the world in order to understand global temperature patterns. Throughout the unit, students collect their findings in a portfolio. The comprehensive curriculum materials contain teacher tools, a Web activity in which students examine 12 months of weather data for several U.S. cities, comparing their findings with the same 12 months at Antarctica weather stations, two hands-on experiments, two Q&A interviews and a student handout with guidance for putting together their portfolios and examples of creative final projects.

This activity, effective outdoors or indoors, demonstrates how insolation is affected by latitude by using a pair of thermometers, each taped to some cardboard, placed outside on a sunny day. A globe can also be used, outdoors or indoors. Students learn that seasonal variations in temperature are the result of the heating of the Sun as a function of its peak angle and length of the day. A template for a folded paper structure to explore the effects of the angle of illumination on heating is included. The resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

In this activity, students use mathematics to understand tides and gravitation and how gravity works across astronomical distances, using an apparatus made from a slinky, meter stick, and a hook. A description of the mathematical relationships seen in the demonstration is included.

Students will be exploring the idea of ecosystems and wildfires. They will become familiar with what an ecosystem is and how to keep them healthy. Students will also see the positive and negative effects of wildfires on ecosystems. Also how wildfires influence the local government and federal government when it comes to land management.

In this problem-based learning (PBL) scenario, students prepare a presentation for investors showing how their fishing company has a significant advantage because it locates upwelling zones and fishing areas using TRMM (Tropical Rainfall Measuring Mission) and other satellite data. Prior to launching the PBL, students learn about wind: the topics of air pressure, coriolis effect, upwelling and the role of differential heating on the atmosphere are explored in classroom demonstrations. Materials required include a beaker, coffee grounds, drinking straw, balloon, flashlight, and turntable. The resource includes teacher background information, glossary, assessment rubric, and an appendix introducing problem-based learning.

In this problem set, students learn about rainfall rates and how to convert them into the volume of water that falls.

This interactive resource from the Exploratorium calculates your weight on other bodies in our solar system and offers an explanation of mass and weight and the relationship between gravity, mass, and distance.

Test the pH of things like coffee, spit, and soap to determine whether each is acidic, basic, or neutral. Visualize the relative number of hydroxide ions and hydronium ions in solution. Switch between logarithmic and linear scales. Investigate whether changing the volume or diluting with water affects the pH. Or you can design your own liquid!

In this activity, learners use basic measurements of the Earth and pieces of rock and iron to estimate the mass of the Earth. Learners will calculate mass, volume, and density, convert units, and employ the water displacement method. To calculate an even more accurate estimate of the mass of the Earth, this resource includes optional instructions on how to measure the iron core mass.
