While it is not content-rich enough to be a standalone instructional tool, Earth-Now could be a great supplemental resource in the classroom. Use it during an earth science unit to track climate data. Assign students to a specific data set and have them record observations for several weeks. As they track data, students can do research to learn more about climate change and the implications of the data they're tracking. It could be fun to have kids create a digital representation of their findings to share with the class or on social media.Continue reading Show less
Earth-Now is a hub for recent climate data gathered from Earth satellites. The data sets are visual color scales that cover a 3-D model of Earth, and students can rotate the model and zoom in or out. A color-coded legend shows the relative weaknesses or strengths of the data sets, which include surface air temperature, carbon dioxide, carbon monoxide, gravity field, ozone, sea level, sea surface salinity, and water vapor.
Kids select a data set from a drop-down menu, and then the most recent data is displayed. By tapping on a "Details" icon, students can read about the data set. They can also tap on an arrow to view animations of the data displays, which may show changes over time. For example, the ocean-surface-salinity animation displays several data sets from the past 10 months. According to the developers, images of large curated events, such as storms and fires, are updated two to three times per week.
Students can learn about recent climate data, which encourages them to think about potential global issues. Brief explanations of each data set teach kids the basics about the data sets they are viewing. The app includes external links to NASA websites that provide more information about climate change and future NASA missions. While these links are useful, it would be great to have more of this information, as well as baseline data, embedded in the app.
Key Standards Supported
Earth and Human Activity
Ask questions to clarify evidence of the factors that have caused the rise in global temperatures over the past century.
Analyze geoscience data and the results from global climate models to make an evidence-based forecast of the current rate of global or regional climate change and associated future impacts to Earth systems.
Use a computational representation to illustrate the relationships among Earth systems and how those relationships are being modified due to human activity.
Develop and use a model to describe how unequal heating and rotation of the Earth cause patterns of atmospheric and oceanic circulation that determine regional climates.
Analyze geoscience data to make the claim that one change to Earth’s surface can create feedbacks that cause changes to other Earth systems.
