Students explore the layers of the Earth and the dynamic changes that they cause on Earth's surface. Volcanoes and earthquakes become the focus of the activity as the Oregon State quarter and its Crater Lake images are linked to the topic.

In this changing seasons worksheet, students read about the geography concept of changing seasons and then respond to 9 short answer questions.

Eighth graders describe how the Earth's position causes seasonal changes. In this astronomy lesson, 8th graders explain how solar radiation varies depending on the season. They create a collage or poster on each of the Earth's four seasons.

Learners read an online article about an earthquake and follow up with a series of discussion questions about earthquakes. They answer questions in their science journals about continental drift, plate tetonics, and their influence on...

How can climate change affect our water supply? Have kids read a passage about the water cycle and water conservation, which includes six questions that challenge them to use context clues.

Students describe and compare the layers of the atmosphere. They explain how to measure the temperature of the atmosphere and discover what causes the atmosphere to heat up in some places more than in others.

Is everything really connected? Take your class on a walk outside, where they will make observations and write them down on a worksheet. Once they are back in the classroom, learners will work to determine if and how things like birds,...

Students observe evidence of erosion and various rock formations that have formed as a result of erosion and weathering. Their task is to explain how the forces of weathering and erosion contributed to sculpturing these rocks into arches...

First in a two-part instructional activity on the greenhouse effect, this instructional activity involves a classroom demonstration of the phenomenon, and a lab group experiment with color and absorption. Although there are easier ways...

Here's a stat for your pupils: 18 percent of the human body is carbon! Part 10 in the series of 12 takes pairs on an adventure through the carbon cycle. After a class reading about carbon, pairs read and choose their own adventure...

Environmentalists test stream water for temperature, pH, and turbidity. Each group shares their information and then the class makes an overall evaluation of the water quality. A slide show sets the backdrop for the teaching portion and...

Space scientists use water displacement to determine the mass of a cubic centimeter mini meteorite, and then use it as a small-scale representative of an asteroid. They figure out the orbital velocity of an asteroid. Then they use a...

Ecosystem, human body system, weather system. We hear the word system a lot, but what does it really mean? In the activity, pairs or groups of learners discuss how a bicycle is a system and then analyze objects in their classroom and...

Writing a persuasive argument starts with a clear thesis. Using this resource, your class will write a persuasive paper on a conservation issue. They will then transform their argument into a 30-second public service announcement. If...

Although recycling is definitely beneficial, reducing our waste and conserving our natural resources should really be the focus of environmentalists. Encourage the future generation to create a public service announcement about a...

Demonstrate the path of the sun across the sky at different times of the year with an engaging science lesson.  Learners use a series of questions and diagrams to examine the movement of the sun and appearance of the sky around...

Why is there so much frozen water at Earth's poles? Because water is a polar molecule! Young scientists observe polar molecules moving in a mixture of oil and water. They see the changes in potential energy in the hydrophilic and...

Turn up the heat! Young mathematicians develop models to represent different climates and collect temperature data. They analyze the data with regression and residual applications. Using that information, they make conclusions about...

What can shadows tell us about the changing season? Over several months, astronomy learners record length and position of an outdoor object's shadow, such as a flagpole. They apply the data to a growing hypothesis and note the...

Young ornithologists watch an informative video and use the Internet to gather data about the life, size, habitat, and migration of hummingbirds. The interdisciplinary lesson includes activities that target art, science, math, and...

To what degree do learners understand coordinates? Get them some practice in Yosemite National Park in a simple, fun interactive. Pupils explore a map and locate coordinates of popular sights within the park, then answer questions...

It is not a barrel of monkeys—it's a jar of worms! Scholars create a worm farm in a spaghetti sauce jar. Pupils layer moist soil, sand, and oatmeal to create a habitat for worms. Individuals place worms into the habitat, cover it with...

Students explore Earth's seasons using an interactive website. In this earth science instructional activity, students watch video segments and explain Earth's seasonal milestones. They discuss the factors that causes seasonal changes.

In this maps worksheet, students read about the Earth, sky, rivers and lakes, and more, and then answer short answer questions about it. Students complete 3 questions.
