Students perform a classroom activity of measuring the angular size of something from several distances. On the Internet, they obtain and examine images with various magnification factors and estimate the angular size of Andromeda.

Students calculate the stride length of a walking or running animal. They use scale models of dinosaurs to calculate the leg and stride length of the animals.

Students determine with math concepts how much plastic pollution is affecting marine life. In this plastic pollution lesson plan, students collect scientific data from a field trip to a water treatment plant.

Learners study the nature of a satellite's orbit around the Earth.

Ninth graders study the origin and organization of the solar system. They investigate the Earth's place in the system and how planetary motions explain natural phenomena observable from Earth.

Young scholars identify the characteristics of aerosols. Using remote sensing, they participate in an experiment in which they determine how the sun's radiation and elements in the atmosphere interact with one another. They also...

Students explain the cause of and effects of fluid shift in a microgravity environment. Students identify the effects of microgravity during long duration space flight. Students describe research on cardiovascular effects in microgravity...

Learners see the difference between weight and mass when they examine the method of measuring each of them.

Third graders watch a video on the solar system and examine the role of the sun. As a class, they complete a KWL chart and make different color temperature pockets to use during their experiment. In groups, they make predictions about...

Seventh graders observe that heat is produced when two substances are combined. They brainstorm how, and then experiment to find out which of two chemicals created the heat.

Students explore the ways in which satellite images provide details of the Earth's surface and how they are capable of taking digital images of the Earth from space they vary in resolution and breadth. They view how cameras and lenses...

Students explore how GPS works, the mathematics behind the technology, and how GPS is used. They find positions in one and two dimensions, and participate in a WebQuest that explores how math is used to find a location on Earth using GPS.

Students take an imaginary hike in two opposite directions along a lake. They view and interpret satellite images and discuss the pros and cons of hydroelectric dams.

Students examine the possibilities of communication with other living organisms within our solar system through research and hands on activities, as well as observing and analyzing teacher demonstrations.

Students are taught that they can gather information about objects using the five senses of vision, touch, smell, taste, and hearing. They are told that some sensing, like sight, is done remotely. Students observe how a camera can...

Young scholars assess the environmental impact of their transportation choices. They keep a transportation journal and use a website to calculate vehicle emissions for themselves and their class. They evaluate their transportation choices.

Students identify and separate the different zones of the beach by observation. They investigate beach zonation by gathering and comparing sand samples gathered from different areas of the beach.

Students practice plotting temperature data points on a line graph in groups and examine the temperature differences at the same time of year. They graph the temperatures in Lannon, WI, and Mitchell's Plain, SA. After the data has been...

Students recycle discarded automobile tires and create gardening sites for limited space areas.

Learners record data, make observations, and share in experimentation and discussion of numerical experiments.

Students design and conduct investigations that illustrate the effect bioremediation has on organic matter and determine environmental applications. They, in groups, present their findings to the class.

Students examine how to plan for prudent use of trees so that we never run out of this natural resource. They determine what the oldest wooden object in their home is and draw picture of it. They observe a cross section of a tree and...

Learners construct a barometer and collect data on the changes in air pressure. They work is small groups using plastic tubing, corks, and green food coloring. They then use a formula to convert inches of mercury to barometric pressure...

Students watch programs from a series titled "Planetary Landers". As a class, they view a poster of various vehicles that have made their way into space. In groups, they brainstorm the characteristics that should be included when...
