Your task today: count all the trees on a tree farm. To complete the assignment, learners first estimate the number of trees on a tree farm using random sampling. To improve their own response they then evaluate provided...

Don't stuff money under your mattress. To find out why learners first complete a task determining how $24,000 in cash would affect the height of a mattress and whether this same amount would fit into a suitcase of given dimensions....

Polygon ... an empty bird cage? After finding the angles of a polygon, young mathematicians use the provided methods to solve the problem in multiple ways.

Who knew running a greenhouse required so much math? Amaze future mathematicians and farmers with the amount of unit conversions, ratio and proportional reasoning, and geometric applications involved by having them complete the...

Explore capillary action from different perspectives. In the fourth installment of a nine-part series, scholars perform several experiments to observe capillary action. They look at the meniscus of water in a glass, observe capillary...

After viewing short clips of unfortunate events, your class will consider two sides of a homeowner's court case, and then learn about the Marcellus shale deposit beneath the state of Pennsylvania and the hydraulic fracturing process. In...

Students stud angles, and then play the "What's Your Angle?" game. They complete at least 10 computer generated problems from the Angles Applet.

Students calculate the size of a molecule. In this molecules and their sizes lesson plan, students find the size of an oleic acid molecule by using a measured amount of drops of oleic acid to find the volume of the sample, the thickness...

Students examine the descriptive science dealing with the surface of Earth, its division into continents and countries, climate, natural resources, inhabitants and industries of the various divisions and analyze the political geography...

Learners observe how measurements are made with different instruments.  For this remote sensing lesson students investigate the physical state of surfaces including the surfaces of the solar system. 

Students gain first-hand experience on how friction affects motion. They build a hovercraft using air from a balloon to levitate a craft made from a compact disk (CD), learning that a bed of air under an object significantly reduces the...

Students list and describe three types of surface water pollutants. They observe the effects of various water pollutants on algae growth. Three causes of each surface water pollutant is listed.

Learners discuss metabolism. In this metabolism lesson, students evaluate evidence form a research report and discuss the basis for hypothetical metabolic adaptations to low-oxygen environments in the anchialine caves.

Students design a model watershed. In this watershed lesson, students learn the needed parts of a watershed and how they work. Students evaluate how watersheds effect communities.

Students explore energy by creating a light project in class. In this kaleidoscope lesson, students discuss the properties of light and how mirrors can reflect the energy in different directions. Students view a diagram of light...

Students investigate the strength of different adhesives. In this physical science lesson, students compare the force needed to peel adhesive tapes from a surface. They analyze collected data and make a generalization.

Fourth graders develop an understanding of how engineers use wind to generate electricity. They will build a model anemometer to better understand and measure wind speed. They discover that engineers design wind turbines that generate...

Seventh graders build a watershed from various materials. In this life science lesson plan, the students will be able to change the design of their watershed to see the changes in the way the water will drain. Each group will be able to...

Students compare and contrast the properties of salt water in the oceans/seas and freshwater elsewhere on the planet. They also analyze mixing caused by currents in the ocean, including the effects of warm and cold water as well as with...

Students investigate the urban heat island effect. In this urban heat island effect lesson, students learn how trees, grass, asphalt, and other things on the school grounds effect temperature. They use the information to generalize it to...

Students explore the causes of erosion and observe how different surfaces erode differently. They recognize erosion and predict what type of erosion caused it. In addition, they predict the outcomes of erosion on different materials.

Young scholars explore what the Bermuda triangle is and the theories as to why it is so mysterious.  In this mystery lesson students read and discuss the history and the mystery behind the Bermuda Triangle. 

Students explore islands. They create a two- or three-dimensional map of an island. They explain how the topography of an area influences the location of water sources, ecosystems, and human settlements. Lesson includes adaptations for...

Learners assess the damage natural forces have caused Maryland's geographic features. In this state geography and ecology activity, students work in a group to research ways in which weathering, erosion, and deposition have affected the...
