Winter Weather Safety Infographic

http://bit.ly/2R7gF8k

It's important for K--12 students and their families to learn how to stay safe in extreme cold and to avoid dangers such as frostbite or hypothermia. A colorful infographic from the CDC presents information about the symptoms of frostbite and hypothermia, along with tactics for avoiding these dangers and guidance on when to seek medical attention.

2019 Marine Debris Calendar

Featuring winning artwork created by K--8 student participants in NOAA's 2018 Keep the Sea Free of Debris contest, this colorful calendar highlights the problem of marine debris and provides links for learning more about it. In addition to creating original artwork, the calendar artists shared their thoughts about what can be done to prevent or reduce the impact of marine debris on the oceans. These ideas included organizing events such as beach cleanup days, recycling metal and plastic products to keep them out of the oceans, and creating signs to inform people about how trash impacts the oceans.

ChemReview Modules

http://chemreview.net/

Use this resource to help advanced high school and undergraduate students review and learn math fundamentals needed to solve calculations and succeed in first-year college chemistry courses. The tutorials are modules (in PDF format) from the textbook Calculations in Chemistry, written by chemistry educators Donald Dahm and Eric Nelson. Module One addresses the topic of scientific notation; Module Two addresses the metric system. To access the materials, click on the link in the upper-right corner (Download Free Chapters), and follow the prompts.

GeoInquiries

These short, standards-based inquiry activities can be used for teaching map-based content found in commonly used textbooks in grades 4-12. Developed by educators at Environmental Systems Research Institute (ESRI), each map-based activity is designed around a common inquiry model and can be presented quickly from a single computer and projector or modified for students' hands-on engagement. Click on a theme (e.g., "Earth Science," "Environmental Science," "Human Geography," or "Upper-Elementary"), and choose from a collection of 15-20 lessons on the topic. The Earth Science collection, for example, contains lessons such as Topography and Our Natural Heritage; North American Landforms; Rock Types Tell Stories; Fluid Earth: Winds and Currents; Rivers: Watershed Analysis; and Oceans: Hot Spot. Most lessons can be completed in about 15 minutes and require only internet access and the lesson plan; however, some more in-depth lessons in each collection require a free school subscription to ArcGIS online. All of the activities engage students in working with data and interpreting maps.

The Whirligig Aerospace Challenge Lab

http://edut.to/2C3a4Bg

Targeted for grades 8-12, this simple activity from Edutopia.org excites students about space exploration and teaches the engineering design process. After watching Seven Minutes of Terror, a video that describes the challenges NASA scientists faced in Curiosity Mars rover's final minutes before landing on the surface of Mars, students are given a challenge of their own: Build the slowest whirligig--i.e., Mars lander--from inexpensive supplies (e.g., tape, paper, and paper clips). As students build their models, they work through several key steps in engineering design: defining problems, making models, carrying out investigations, interpreting data, constructing and designing solutions, and communicating information. Find the activity, which includes teacher instructions, whirligig templates, a student reflection sheet, and links, at the site. …
