Experiment with a helium balloon, a hot air balloon, or a rigid sphere filled with different gases. Discover what makes some balloons float and others sink.
Students explore static electricity by rubbing a simulated balloon on a sweater. As they view the charges in the sweater, balloon, and adjacent wall, they gain an understanding of charge transfer. This item is part of a larger collection of simulations developed by the Physics Education Technology project (PhET). The simulations are animated, interactive, and game-like environments.
The term "global average temperature" is defined and its importance in monitoring climate change is discussed. A supplemental column makes the analogy between Earth’s temperature and human vital signs. This lesson is part of the Climate Kids website, a NASA education resource featuring articles, videos, images and games focused on the science of climate change.
NASA scientists, using several NASA Earth observing satellites, continue to seek answers to questions related to climate change. Several of those questions, focused on such topics as the effect of clouds and aerosols, and the role of the sun's cycles and the carbon cycle, are included in this article. Images of the respective satellites involved in the research are shown. This article is part of the Climate Kids website, a NASA education resource featuring articles, videos, images and games focused on the science of climate change.
This article describes common misconceptions held by elementary students about the history of the polar regions, fossils, and geologic time. The article provides ideas for formative assessment, teaching strategies, and the National Science Education Standards.

This is a quick activity that shows how large amounts of rock and sediment are added to the edge of continents during subduction. You may ask, how can such a huge phenomenon be demonstrated quickly and cheaply? The answer is simple: with a cookie!
This 6-minute clarifies the first living things to colonize land. [Cosmology and Astronomy playlist: Lesson 42 of 85]
In this activity, learners use crayons to draw conclusions about rocks and the rock cycle. Learners form crayons ((which can be "weathered"--heated, compressed and cooled--like rocks) into models of sedimentary, metamorphic, and igneous rocks.
Most of our oceans still remain a mystery. Dr. Chris Massell Symons shares how scientists are exploring the depths to uncover their secrets. We'll also find out about a fun song to "lure" your students into learning about our "One Big Ocean."
This article highlights lesson plans and activities that help elementary students develop map skills as they learn earth science concepts.
This activity is a bioassay lab where students tested the effect of an environmental toxin (fertilizer) on the growth rate of Duckweed.
Earth science is the study of our home planet and all of its components: its lands, waters, atmosphere, and interior. In this book, some chapters are devoted to the processes that shape the lands and impact people. Other chapters depict the processes of the atmosphere and its relationship to the planets surface and all our living creatures. For as long as people have been on the planet, humans have had to live within Earths boundaries. Now human life is having a profound effect on the planet. Several chapters are devoted to the effect people have on the planet. Chapters at the end of the book will explore the universe beyond Earth: planets and their satellites, stars, galaxies, and beyond.
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.
This lesson teaches the students about the different layers of the Earth and how they work together. Students will be able to: Name and label the four layers of the Earth; Identify the main minerals that make up each layer; Explain how scientists formulated the idea that the Earth is comprised of four layers.
Students learn about the wonderful and fascinating country of China, and its environmental challenges that require engineering solutions, many in the form of increased energy efficiency, the incorporation of renewable energy, and new engineering developments for urban and rural areas. China is fast becoming an extremely influential factor in our world today, and will likely have a large role in shaping the decades ahead. China is the world's largest energy consumer and the largest producer of carbon dioxide emissions, leading engineers and scientists to be concerned about the role these emissions play in rural and urban public and environmental health, as well as in global climate change. Through exploring some sources of air pollution, appropriate housing for different climate zones, and the types of renewable energy, the lessons and activities of this unit present ways that engineers are helping people in China, using an approach to cleaner, smarter, healthier and more-efficient ways of living that apply to people wherever they live.
As part of this activity, students learn about geologic processes on Earth in order to interpret surface features recently seen on Europa by NASA's Galileo spacecraft. Materials presented here include a vocabulary list, geology jigsaw puzzle, review questions, and links to related sites.
In this inquiry based geologic field lab students will be estimating and measuring stream flow. Students will also map out a full scale live topography map of a dry streambed to help them estimate flow discharge. Students will use their journals to record their hypothesis, lab report questions, graphed data and evidence to backs up their observations.
Explore pressure in the atmosphere and underwater. Reshape a pipe to see how it changes fluid flow speed. Experiment with a leaky water tower to see how the height and water level determine the water trajectory.
Pump gas molecules to a box and see what happens as you change the volume, add or remove heat, change gravity, and more. Measure the temperature and pressure, and discover how the properties of the gas vary in relation to each other.
