Earth Turns? Prove it!

In this demonstration, evidence of the Earth's rotation is observed. A tripod, swiveling desk chair, fishing line and pendulum bob (e.g., fishing weight or plumb bob) are required for the demonstration.

Plotting Pulsating Variable Stars on the Hertzsprung-Russell (H-R) Diagram

The H-R diagram is a scatter graph of stars, a plot of stellar absolute magnitude or luminosity versus temperature or stellar classification. It is an important astronomical tool for understanding how stars evolve over time.

Carbon Cycle and Life

In this lesson, learners explore the steps in the carbon cycle and draw conclusions about the importance of the carbon cycle in the planetary temperature system.

Spoon Mirror

Using the reflection seen in the bowl of a spoon as an example, this resource describes how an everyday childhood observation can lead to understanding how curved mirrors are used in telescopes and satellite dishes.

The Inverse-Cube Law of Magnetic Forces

This is an activity about the magnetic deflection. Learners will observe and measure the deflection that an iron mass causes in a soda bottle magnetometer and plot the data. The data should show the inverse-square cube law of change in the magnetic field.

Mars for Earthlings: Integrating Introductory Geology with Mars Planetary Data

This series of learning modules is designed for adaptation in an introductory Earth science or planetary science course. The modules actively engage students through Mars remote-sensing data and Earth-based analogs to understanding Mars geology.

GLOBE: Pedosphere (Soil) Protocol eTraining

The pedosphere (soil) is the focus of this GLOBE eTraining program module. Protocols for investigating soil temperature, moisture, characterization, density and infiltration are explained. In addition, each module includes interactive digital field and lab experiences, and online assessments.

Earth Exploration Toolbook: Exploring Regional Differences in Climate Change

In this activity, users download and graph modeled climate data to explore variability in climate change. Most people know that climate changes are predicted over the next hundred years, but they may not be aware that these changes are likely to vary from region to region.

MY NASA DATA: Earth's Energy Budget - Seasonal Cycles in Net Radiative Flux

Net Radiative Flux (NRF) is used to determine the flow of solar energy in and out of the Earth system. NRF is influenced by seasonal variations related to the tilt of the Earth's axis and degree of cloud cover as well as Earth’s surface features.

What is Global Systems Science?

In this introductory textbook chapter, students become familiar with how scientists view planet Earth. This is the first chapter in the unit, A New World View, which introduces global systems science, emphasizing the concepts of environmental diversity, Earth as a system, and sustainability.
