CK-12 Earth Science For High School covers the study of Earth - its minerals and energy resources, processes inside and on its surface, its past, water, weather and climate, the environment and human actions, and astronomy.

Students will explore the relationships and patterns among the Earth, Sun, and Moon system in our solar system. Students will design, build, and test a model of a lunar rover.
When the North Pole is tilted toward the sun in the summer, the Northern Hemisphere experiences more daylight. This results in longer days and warmer temperatures.
Earth's axis runs from the north pole to the south pole and is tilted at 23.5 degrees. Rotation is the spinning of Earth on its axis. It takes 24 hours to make one complete rotation.
The moon goes through several phases based on its position in relation to the sun and Earth. When the moon is between Earth and the sun, none of it is illuminated and it is referred to as a new moon.
Earth's tilt on its axis is responsible for the different seasons.
Earth bulges slightly at the equator and flattens slightly at the poles.
The sun is huge compared to Earth. About one million planets the size of Earth could fit inside the sun.
Earth spins, or rotates, at a speed of about 1600 kilometers per hour at the equator.
The tilt of Earth affects the length of day. When the north pole is tilted away from the sun, the northern hemisphere experiences less daylight. But when it is tilted toward the sun, it receives more daylight.
Waning refers to the process of the full moon growing darker as the moon revolves around Earth. The animation depicts the last quarter phase, from which it slowly grows darker and disappears until it becomes a new moon, starting the cycle over again.
This video segment adapted from NASA's Goddard Space Flight Center discusses how a drought can have negative effects locally, for example by increasing the number of forest fires, and also globally, for example by impacting air quality thousands of miles away.
This video segment adapted from NASA's Goddard Space Flight Center describes El Niño, how it forms, and the chain reaction of consequences it triggers around the globe.
This video segment adapted from NASA's Goddard Space Flight Center explains how hurricanes develop and why there are fewer hurricanes in the Atlantic Ocean in strong El Niño years.
This video segment adapted from NASA's Goddard Space Flight Center shows how integral satellites are to everyday life and describes the different types, including orbital and geostationary.
Students shape up their reading, writing, and listening skills in this lesson by creating original diamante, acrostic, and shape poems about science.
In this lesson, students will engage in a creative assessment of Earth's systems and their interactions. Through the creation of a stop motion animated story, students will demonstrate their understanding of how different Earth systems interact. Working in groups, students will select at least two Earth systems to portray in their stop motion film, using playdough. This lesson is designed to span 3 45-minute blocks, allowing time for brainstorming, planning, and presenting their animations.
