Installment eight of the 10-part Discover Your Changing World series tests the class's understanding of climate. Scholars play alone or in small groups to assess their understanding of climate systems, causes of climate...

In 150 BC, Seleucus of Seleucia theorized that the moon causes the tides. Scholars learn about what causes tides by studying the interactions of gravity between the sun, moon, and Earth. They use technology to formalize otherwise...

This science assignment produced by NASA teaches inquiring minds the distribution of Earth's water. Learners will appreciate and understand the importance of fresh water and how weather and climate affects everything.

Students consider the affects of space travel on the human body. In this human physiology lesson, students compare how the 5 different body systems work on Earth and in Space. Students then design a product that an astronaut could use as...

Take your science class on a hypothetical field trip to Mars with an engaging astronomy lesson. After first learning about NASA's Mars rover missions, young scientists plan their own scientific investigations of Earth's...

Searching for an eclipse activity that sends scholars over the moon? Try an interesting interactive to get their minds active! The resource, part of an extensive Space series from PBS Learning Media, uses modeling and data analysis to...

Explore the sun in a lesson plan about space. The lesson spans ten weeks, with students performing activities to answer weekly questions about the Sun and Earth.

This PowerPoint is a comprehensive review of all the facts related to an atom's basic structure and function. What makes this unique is that it is geared toward an audience of junior geologists. After introducing the periodic table of...

If you need a comprehensive review of the development of Earth's atmosphere through the ages, then this is for you! The presentation starts with a introduction to theories of planet formation and initial distribution of isotopes in the...

Chemistry and earth science meet in a lesson on carbon dioxide emissions. After reading about atmospheric problems caused by using fossil fuels, science stars balance equations for the burning of different alkanes. They compute the...

How is solar energy able to move wind and water to control the climate? Scholars explore the concept of solar energy in the first of 10 activities in the Discover Your Changing World series. They follow instructions to build homemade...

Ninth graders set up a scale model of the solar system using the same scale for distance and diameter. They calculate scale distances and sizes for modeling the solar system and relate actual distances to difficulties in discovering and...

People may not be able to jump over the moon, but scientists can still study it! The moon is covered with mons (mountains) and mars (seas). Aspiring astrologists learn about the moon's features and phases in a PowerPoint presentation. In...

Space scientists investigate the cosmic phenomena in order to search for answers to possible origins of the solar system. They consider the concepts of elements and  isotopes. Data is analyzed looking at tje abundance of elements...

Researchers think they have evidence of a new planet deep in our solar system that is the size of Neptune and orbits the sun far beyond Pluto. The orbit simulator shows the orbits of our well-known planets, as well as Pluto and the comet...

Why is the weather man wrong so often? Young climatologists discover how chaos rules both weather and climate through a math-based activity. Using an iterative equation, the class examines how small day-to-day weather events total up to...

Mercury, Venus, Earth, and Mars are collectively known as the terrestrial planets. Although part of the same group, each planet has its own set of characteristics. Scholars explore the characteristics that make the planets unique and...

When van Leeuwenhoek saw cells and single-celled organisms for the first time, he knew these small things were a big deal! Share his discoveries with young learners through a narrated video, model-building activity, and scale study....

Young scholars explain that there are pollutants in the Anacostia River, what those pollutants can cause, and how to prevent further pollution. They read about pollution and graph levels of fecal coliform in the water.

Students describe the components of an HVAC system and determine which factors influence how efficient the system can be. They work together to develop hypotheses about the systems and their cost effectiveness and efficiency.

Students examine GIS technology as it is used to locate energy sources. In this GIS lesson, student access an assigned website to locate a series of lessons using the GIS software. They use the maps that are located on the primary lesson...

Students become familiar with different times around the world through the reading of 9 O'clock Lullaby.  In this Earth, sun, moon activity, students recognize the movement of the Earth and the relationship to the sun and the...

In this solar system activity, students complete a crossword puzzle given 11 clues about objects in the sky such as asteroids, meteoroids, comets and planets.

An interesting lesson takes pupils on a trip through the carbon cycle. A reading passage allows scholars to take notes and make choices about what happens to the carbon on its journey. This third lesson in a series of 21 discusses...
