Knowing how to mix concrete is a big part of having a construction job. Here vocational learners will go through the types, economy, and uses for concrete. Each slide is rich in text but organized in an easy-to-read style. Images and...

In this physics learning exercise, students complete 11 short answer questions related to general metrology. They define basic metrological terms.

Third graders explore the difference between a physical change in a substance and a chemical change. students study the volume, density, altering shape and chemistry of a copper penny.

Learners analyze the amount of space required to pack round objects. In this geometry instructional activity, students practice using space economically by practicing packing spheres into beakers. They then translate this concept to...

Students construct aluminum foil boats that float while holding the greatest number of pennies. They investigate the concept of water displacement, record their results, and watch a Bill Nye video on buoyancy.

Students analyze data taken from proteomic experiments. In this biology lesson plan, students explain the importance of bioinformatics tools in the study of proteins. They evaluate scientific results using math and computer software.

Students form "companies" of 3-4 students and build bottle rockets for analysis and experiment. This lesson uses NASA's RcketModeler Version 1.2 rocket simulator to evaluate each rocket's flight.

High schoolers examine World War I war crimes. In this world history instructional activity, students use primary and secondary sources to research and understand the systematic nature of the Armenian Genocide. High schoolers reflect on...

Fifth graders observe and compare apples. In this apples activity, 5th graders work in groups to record the physical characteristics of a variety of apples. Students predict each apples weight and then weigh them to see if they were...

Young scholars examine why diffusion and osmosis happen in an egg cell.  In this diffusion lesson plan students demonstrate a semi permeable membrane.

Students learn the metric units engineers use to measure mass, distance (or length) and volume. They make estimations using these units and compare their guesses with actual values. To introduce the concepts, the teacher needs access to...

Students learn about the concept of pushing, as well as the relationship between force and mass. Students practice measurement skills using pan scales and rulers to make predictions about mass and distance. A LEGO MINDSTORMS NXT robot is...

This activity can be used to explore forces acting on an object, to practice graphing experimental data, and/or to introduce the algebra concepts of slope and intercept of a line. A wooden 2x4 beam is set on top of two scales. Students...
