In this activity students use a simple model of the moon to do an experiment to see how impact craters are formed. The lesson worksheets are differentiated and students are put into pre-determined teams by ability to conduct the experiment.

This article highlights resources that can be used to supplement lessons on extreme weather, including games and video clips. The article appears in the free, online magazine for K-Grade 5 teachers Beyond Weather and the Water Cycle. The magazine focuses on the essential principles of climate science.

This activity is a lab investigation where students design their own lunar phases model using household materials.

This activity is a reinforcement activity where students will make a flipbook of the lunar phases.

This set of activities is designed to help students develop an understanding of scale/distance and ordering the planets from the sun, understanding Earth's position in the solar system, and developing new ways of determining "order."

This is a classroom activity in which students will observe, question, and investigate the relationship between the sun and the earth and how that relationship causes day and night.

In this video segment adapted from NOVA, a scientist explains the unexpected heat source fueling widespread volcanic activity on Io, a moon of Jupiter that many had previously assumed to be frozen.

In this activity, students identify spirals and other shapes present in nature and discuss at what sizes or scales these shapes exist. Examples include a hurricane, foraminifera, nautilus, and a galaxy. They will discuss the differences and similarities of each of these spirals and investigate the powers of ten that identify the scales at which these different examples exist.

This experiment uses the heating of water to explore the concepts of density and volume. Students learn about the transfer of heat energy within the atmosphere, hydrosphere, and Earth's interior, and connect this transfer to differences in density, which in turn result in motion. As part of the investigation, students will also become familiar with the Celsius and Fahrenheit temperature scales.

In this activity, students organize a set of fossils chronologically and learn to correlate, based on fossil evidence, the stratigraphy of one location with that of an adjacent location. Earth Science Reference Tables are used to identify the epoch of occurrence and the age of each of the fossil specimens. Students will become familiar with the concept of index fossils and understand what makes a good index fossil.

This lesson helps students explore the functions of the kidney and its place in the urinary system. Students learn how engineers design instruments to help people when kidneys are not functioning properly or when environmental conditions change, such as kidney function in space.

In this final lesson of the Dancing Lights curriculum, students will reflect on and discuss what they learned about the aurora. First, students will compare what they know now with what they knew at the beginning of the program, and discuss their answers with a partner using Think, Pair, Share. The entire class will create a new KWL (Know/Want-to-know/Learned) chart on the board before turning in their individual work.

This 2-page color fact sheet briefly describes NASA's Kepler mission, its instruments, and ground system. Also included are tables listing the instrument parameters and the major institutions involved. Kepler is a spaceborne telescope specifically designed to survey our region of the Milky Way galaxy to detect and characterize hundreds of Earth-size and smaller planets in or near the habitable zone. The habitable zone encompasses the distances from a star where liquid water can exist on a planet's surface. Note: The fact sheets states that the Kepler Telescope was launched in 2007 but did not launch until 2009.

In this video from Science City, Kerri-Ann Richard, an environmental engineer, describes how she became interested in the field and why it is important to clean up the environment by removing contaminants from soil and ground water.

ZOOM guest Amy wants to be a meteorologist and volunteers at a weather observatory. In this adapted video segment, she shows us instruments used to predict the weather and describes how air pressure affects weather patterns.

In this activity, students will model the time after the Big Bang when the first nuclei of hydrogen and helium were created. The students will move and display cards that show the elements that are formed. This activity requires a large area - e.g., an outside location, a large classroom with seats moved back, or a gym. This activity is part of the "What is Your Cosmic Connection to the Elements" activity and information booklet. The booklet includes teacher notes and instructions as well as follow-up questions.

This activity shows how our experience of the Sun changes with time and location. The sun dagger at Chaco Canyon is thought by many to be a sort of ancient timekeeping device. By creating a place where the movement of the Sun could be tracked day after day, Chacoans could mark the passage of time and gain an idea of when seasons were changing. If the Chacoans could use a particular location and the Sun to tell them about time, can we use time and the Sun to tell us about our location? In this easy experiment, you'll see how the position of the Sun in the sky is related to where we are on the earth.

In this Nature video, follow geologists as they retrieve samples from a fresh batch of Kilauea's molten lava.

In this video profile produced for Teachers' Domain, meet La'ona DeWilde, an environmental biologist who integrates her Athabascan heritage and her Western scientific training to help remote Alaskan villages address environmental issues.

Isaac Newton's famous thought experiment about what would happen if you launched a cannon from a mountaintop at a high velocity comes to life with an interactive computer model. You are charged with the task of launching a satellite into space. Control the angle and speed at which the satellite is launched, and see the results to gain a basic understanding of escape velocity.
