How has Gorongosa National Park changed over time? Discover the park's rich history, dating back to primitive human times, through an interactive timeline and scientific reading. The second installment in an eight-part series explores...

Finish or launch your unit on the solar system with a jigsaw project covering major celestial concepts such as the Milky Way Galaxy, asteroids, meteors, comets, Earth's moon, and, of course, all the planets. Learners start by...

Individuals in your class research the origin of an animal and present their discoveries to the class. The first appearance of the animal and its date of extinction are indicated on a class time line. 

This demonstration of solar ponds can be used in an earth, environmental, or physical science setting. Lab groups set up a solar pond and model how it is able, due to a salt concentration gradient, to maintain heat for future use. 

Water with varying amounts of dissolved salt are dyed and then used to compare densities. The objective is to discover the effect of salinity, and therefore density, on ocean water on the stability of the ocean. Many branches of science...

Check out a resource that's erupting with engaging material! Earth science scholars discover how igneous rocks form in a well-rounded interactive. They manipulate the cooling time of lava to watch crystals form, learn visual...

Blast off! How do satellites, space shuttles, and space stations escape Earth's gravity and achieve orbit? Young astronauts study rocket science (literally) with an interactive lesson. They discover the four main uses for satellites, how...

Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

Show the six-minute video, "Changing Planet: Fading Corals," and then demonstrate how calcium carbonate forms a precipitate in the presence of carbon dioxide. Separate your scientists into small groups to gather information about coral...

Students research and explore the earth's past and make comparisons with the earth's present. They map out a timeline that explains how the earth and its organisms have changed over time. Studnets create a scale for their time line, they...

Students figure the number of half-lives since the sample solidified, and therefore the "age" of the sample rocks.

Young scholars observe a teacher demo on how clouds form. In this earth science lesson, students discover how cloudiness affects relative humidity. They explain the scattering of light by clouds.

Students create a calendar for an imaginary planet. In this earth science lesson, students analyze the errors on the different calendars used on Earth. They present their work in class.

Students identify and analyze how the geologic time scale was developed by investigating 11 periods of time and the vast expanse of time of the Earth's existence. They study their period, determine the important factors indicative to...

Students calculate wind chill using a mathematical formula. In this earth science lesson, students compare the wind chill in Antarctica to that of their local area. They explain how this can lead to hypothermia.

Students test turbidity, pH, oxygen content and temperature of local stream. In this earth science lesson, students collect and record data from the experiment. They analyze findings and present it to class.

High schoolers reflect on and discuss theories of how the solar system was formed. They respond to prompts in a structured sequence to relate the formation of the solar system and the age of the Earth.

Young scholars label the fault lines and tectonic plate boundaries on the world map. In this earth science instructional activity, students simulate ocean floor formation using CEENboTs. They explain the causes of earthquakes.

Students research news articles relating to global climate change. In this earth science lesson, students create a news broadcast using the information they gathered. They present this in class and each student gives their peer...

Students count the number of varves (annual layers of sediment) in shale billets, taken from the Green River Formation in Wyoming. The count is then extended to reflect the entire 260 meters of sediments where the billets originated.

Students conduct a simulation to determine radioactive decay and half-life. Using pennies, dice or sugar cubes as isotopes placed in shoe boxes simulating rocks, they hold five trials representing 1000 years each to find the theoretical...

Students explore how to read fossil range charts. They develop an knowledge of the strengths and weaknesses of the fossil record. Students become familiar with the concepts index fossil and fossil range. Students use bar graphs to...

Sixth graders engage in problem solving, communicating, reasoning, and connecting to represent and solve problems, using geometric models.

Learners are able to identify natural resources from a shared reading by highlighting, scoring at least a 3 on a 4 point rubic. They describe in journal entries, after reading the book Amelia Bedelia Goes Camping or Curious Geogre Goes...
