Earth’s Magnetic Field

If you found yourself in the middle of the ocean, do you think you could find your way home? Sea turtles can, thanks in part to Earth’s magnetic field!

Educational Resources

For teachers and educators: Earth Science Week 2022 will be celebrated from October 9 - 15, with the theme "Earth Science for a Sustainable World." During Earth Science Week, we hope that you will bring some aspect of Earth Science into your classroom, and take your classroom outside! Your students will not only learn something new about the world around them, but will have fun discovering why Earth Science is important to society.

Energy and Population

Just as your GPS helps you make sure you’re getting from point “a” to point “b” correctly, maps help scientists draw important conclusions and visualize important concepts they study. The right map can help a petroleum engineer find the best drilling site, or help a meteorologist make the best prediction. This interactive mapping activity will help you understand the relationship between the population of a given state and the amount of energy consumed there.

Energy Efficiency

Even in an area with an extreme climate, the ground maintains a relatively constant temperature. Because of this, a house that is built partly or entirely underground can be more energy-efficient than a home above ground. During the winter, the ground is warmer than the air. During the summer, it is cooler. Any large mass of earth tends to maintain a constant temperature. You can see for yourself how this works by testing how long it takes for a thermometer buried in sand or soil to reach the temperature of surrounding air.

Engineer a Satellite

In this activity, you will select the scientific instruments for your satellite, calculate the power requirements for all the subsystems, and construct a scale model of your very own Earth observing satellite.

Enliven Data With Art

There are many reasons people look to art for expression. Art is a means to express emotion, document events, and convey information. In this exercise, you will select a scientific graph that addresses an important real-world issue, create an illustrated graph from that original, and craft an effective artist’s statement that connects the two. Once you’re done, keep an eye out for other ways you can merge science with art. The possibilities are endless!

Erosion in a Bottle

Soil erosion is the process of moving soil by water or wind — this happens naturally or through human interference. Preventing soil erosion is important because nutrients are lost, and sediment that accumulates in waterways impacts life there. Conserving soil depends on how it is protected by plants and coverings.
You will model erosion by water and compare the amounts of runoff and soil loss generated from three different ground cover types.

Exploring 'Wild' Places with GIS

Regardless of where you live, engaging with the landscape means exploring spatial relationships between human and natural phenomena. Geographic information systems (GIS) technology (www.gis.com) provides an effective way to visualize and analyze these places, and your contact with them.

Exploring Caves

An instructional unit on caves for grades K-3. Five short chapters, with follow-up activities and lessons.

Exploring Change with GIS

On our ever-changing Earth, conditions may change quickly or slowly. Some changes come from natural processes; some from human activity. Satellites allow us to see conditions and track changes over time — in land use, forest health, land/water interface, and so on. Since 1972, Landsat satellites have been collecting data using various portions of the visible and invisible electromagnetic spectrum, at a scale close enough to see highways, but not individual buildings on a city block.
