Students investigate Nanotechnology. In this physic's lesson, students evaluate a hands-on model made from chocolate syrup and pretzels to determine the advantages of size.  Students weigh chocolate syrup to determine it's wait...

Get things moving with this elementary science unit on simple machines. Through a series of nine lessons including teacher demonstrations, hands-on activities, and science experiments, young scientists learn about forces, motion,...

All soil is not created equal! A lab activity asks learners to collect and analyze soil. Specific calculations determine the amount of sand, silt, and clay in a sample and allow individuals to identify the soil texture. 

Young scholars build and apply concepts of geometry. In this geometry lesson, students create a building using proportions and scale drawings. They use Cabri technology to create a virtual drawing first.

Students solve linear equations using two steps. In this algebra lesson, students add, subtract, multiply and divide to solve linear equations. They apply concepts of equations to a robot pulling cargo.

High schoolers investigate the Chernobyl nuclear disaster by mapping out the winds carrying radiation and viewing a short video about the aftermath and subsequent health problems. They then calculate the amount of radiation that people...

Two students are blindfolded and each receives a cardboard square, one with pompoms glued around the edge and one with pompoms glued all over the surface. They identify what they feel. The class discusses perimeter and area of polygons....

Learners listen to story, "The 100-Pound Problem," compare their weight with character in story, and weigh different classroom items using nonstandard units and standard units. They experiment with different items that can make scale...

Third graders explore tessellations and the spatial concepts used in creating them.  In this tessellations lesson, 3rd graders rotate, reflect and transform shapes to create tessellations.  Students become familiar with the...

In this black holes worksheet, students use a formula for time dilation which causes delays in events that occur near the black hole. They solve 6 problems using the equation.

Young scholars examine stoichiometry. In this chemical reaction and mole instructional activity, students complete an experiment based on readiness levels to explore that changes are quantified in chemical reactions.

Students explore the basic geometric shapes and geometric shape vocabulary through the use of geoboards and virtual geoboards. They create a variety of shapes with a partner, build ten different rectangles on their geoboards, and...
