This activity will have students collect data, graph it, and compare the information to what they already know about radioactive elements and dating the planet's age.
The atmosphere is a mixture of gases. Similarly, the world's oceans and fresh waters contain dissolved chemicals. Many substances dispersed in air or water are measured in parts per million. Some of these substances are colorless, odorless, and tasteless, yet even in small quantities they can be toxic. To develop an understanding of parts per million as a concept, teams of students will create successive dilutions of a solution to reach a parts-per-million concentration.
As a citizen scientist, you can use a soil test kit to find out how much of each type of chemical is in your soil.
People find inspiration in many different places and things. Among them is taking joy in sensing the Earth around you. Feel the breeze on your face. Take in the fresh smell of the air after a spring rain. Use your hands to build something. Wherever you live you can get outside, savor your surroundings and observe what makes up the rhythms of the place you live.
Dendrochronologists use tree rings to go back in time to learn more about past climate. Using straws to recreate tree rings, you can learn how dendrochronologists work.
Learn about the Earth's magnetic poles and paleomagnetism in this activity from Consortium for Ocean Leadership.
Learn how to make a compass using household objects!
A refuge is a place where you can record observations of seasonal changes to plants, trees, and wildlife. You can use GPS (global positioning system) data to mark an observation spot and record your observations. Then, if you can, visit the same national wildlife refuge during other seasons in the year to document changes in the natural world.
Today, people are “mapping our world” with the aid of Geographic Information Systems (GIS) technology. Mapping can be done in the field or the lab—even from smartphones. You can make maps with real-time data about wildfires, tsunamis, and tornadoes. You can make maps with imagery collected with visible light, infrared, and radar data.
A map can represent data from an area on a flat surface. The part of our Earth system most frequently mapped is the atmosphere. Weather—the state of the atmosphere at a particular place and time—needs constant monitoring because it perpetually changes as weather systems evolve and move.
Awareness of what the weather is and is likely to be has numerous benefits. Weather can be hazardous, causing injuries, death, and loss of property. Weather maps are valuable analytical tools for informing people about current or future conditions.
