Development of a Habitable Planet

Throughout this earth science exam, high school geologists complete a series of multiple-choice and short-answer questions about the solar system, atmosphere, and Earth system. This is an amazing test, as are all of the exams developed...

Researchers use scientific data to understand what is inside each of the planets. The first in a series of six, this instructional activity builds off of that concept by having pupils use a data table to create their own scale models of...

Amaze your class with the fact that more than 1,000 confirmed planets exist. The video explains the formation and development of planets, especially the earth. It covers the solar nebula, birth of the sun, and the development of the...

Planet Earth has come a long way from its dramatic beginnings. How long did all of these changes take? Science sleuths unravel the often-tangled timeline of our progress from single-celled sea creatures to world-traveling homo sapiens in...

Pair earth scientists up to use an amazing online arctic portal mapping tool and Google Earth to analyze permafrost changes. They compare changes to data on atmospheric concentrations of methane to see if there is a correlation. Then...

Scholars discover the amount of the Earth's water in various locations such as the ocean, ice, the atmosphere, etc. They then make a model of the how much water those percentages represent. Finally, analysis questions bring the concepts...
