Students discover how crystal structures go together to create minerals.  In this earth science instructional activity, students work in groups to create 3-dimensional shapes of crystals that they then put together in a compact...

Students examine clouds. In this technology skill lesson plan, students identify different cloud types, observe and photograph clouds in nature, and print and write a riddle about the objects they see in the clouds.

Emergine space engineers discover the area of complex geometric shapes. They find that, just as a spacecraft is composed of many smaller parts, so can polygons be broken into smaller shapes.

Students explore different sounds. For this sound lesson, students participate in an egg hunt. The eggs are filled with different materials and hid around the room. Students find the eggs and chart the different sounds they hear....

Learners write electron configurations and identify groups.  In this investigative lesson students use valence electrons to draw electron dot structures. 

Students practice using objective and quantitative means to describe and compare the weather. They compile weather conditions and create a spreadsheet to record their findings.

Students identify the properties and theorems of triangles. In this geometry lesson, students construct angle bisectors using a compass and straight edge. They identify triangular similarity and congruency.

Young scholars investigate Menelaus Theorem. In this geometry lesson, students calculate the area of polygons. They differentiate between boundaries point, interior points and area of lattice points.

Young scholars prove and use Ceva's Theorem to solve problems. In this geometry lesson plan, students analyze polygons for patterns and calculate the area of each shape. They relate polygons to the real world.

Students study the American Revolution using Google Earth and United Streaming online resources. In this American Revolution activity, students complete a KWL chart with information they know about the American Revolution. Students then...

Students explore the physical properties of density. In this hands-on lesson, students calculate density and distinguish between intensive and extensive properties.

Students examine the different changes in matter.  In this chemical change lesson students determine the amount of reactant made in a reaction using the law of conservation. 

Learners identify different parts of a prism and polyhedra. In this geometry lesson, students identify the number of faces, edges and sides of polygons. They solve problems by recognizing patterns.

In this space science worksheet, learners read about the space shuttle mission and answer 6 short answer questions about life of astronauts in space stations.

Students become familiar with common microorganisms and experience exploring the microbial world.

Middle schoolers dentify the period of the Lewis and Clark Expedition and the life of Sacagawea on a timeline that demonstrates the chronology of important events in American History.

Seventh graders examine the controversial role of Christopher Columbus. In this Christopher Columbus instructional activity, 7th graders determine what Columbus was like and what his motivations were as they research print and Internet...

Students explore basic transportation vehicles, specifically air, land, and water vehicles, name six different modes of transportation, identify four different kinds of train cars, and three differences between two different modes of...

Ninth graders research the work of Carlos J. Finlay and his contributions to science. Once they have discussed his theories about diseases, they create tables comparing diseases that use insects as carriers. The lesson also includes a...

First graders practice rhythm and beat. In this music instructional activity, 1st graders sing and clap to the song "Yankee Doodle Dandy".  They find the rhythm of the music and practice making rhythm with other instruments.

Seventh graders examine music examples to investigate a conflict in history about Hitler's invasions during WWII. In this music analysis lesson, 7th graders discuss vocabulary and the history for the Holocaust and Hitler's invasions....

Students solve for the area and perimeter of polygons. In this geometry lesson, students identify repeated patterns and create formula to solve problems. They make conjectures and prove hypotheses.

Students describe the physical characteristics of dinosaurs, compare and contrast the evolution of land, and they explore the extinction of dinosaurs.

Students use space technology to monitor migratory species, map their movements, and gather data about their habitats and possible responses to climatic shifts.
