Students identify features that make an automobile practical for a cross-country trip and then design a 1903 era auto using lessons learned from Horatio's journey.

Young scholars discover how viruses effect living organisms. Focusing on HIV, they explain why it is unique and how it attacks the immune system. They simulate the spread of viruses through an experiment using water containing sodium...

Students are introduced to the biomechanical characteristics of helmets. They incorporate these characteristics into designs for helmets for various applications. They understand that using a bicycle helmet helps to protect the brain and...

Learners study the main methods to measure earthquakes; the Richter Scale and Mercalli Scale. They make a model of a seismograph and investigate which structural designs are most likely to survive an earthquake.

Students design and create their own heart valves out of a variety of materials. Their heart valves are one way valves designed for water flowing through a tube representing blood moving through the heart.

Students study concepts of energy and energy transfer. They look at how these concepts apply to musical instruments. They study the law of conservation of energy. They use the concepts studied in the lesson to design a musical instrument.

Students investigate the friction between tires and the road and how it affects the movement of cars while driving. They discuss and define friction, experiment with sandpaper and wax paper to determine which material provides the least...

Students design and build a device to protect and accurately deliver a dropped egg. They review and study a number of vocabulary words that are associated with this lesson. They work in a small group in order to develop a successful...

Students use vector analysis to examine the concept of dead reckoning. They listen to a teacher-led lecture, complete a Vector Voyage Worksheet with the teacher, answer discussion questions, and use the Pythagorean Theorem for speed...

Students conduct a simple inertia demonstration by spinning a hardboiled and raw egg. They push a wagon to demonstrate inertia. They explore Newton's first and second laws of motion.

Students triangulate using a compass, topographical (topo) map and a view of outside landmarks. They take a field trip to another location away from school and mark discernible landmarks (like mountains or radio towers) and changes in...

Students examine the concept of angular momentum and its correlation to mass, velocity, and radius. They listen to a teacher-led lecture, conduct an experiment with rotational inertia, angular momentum, and rotation speed by making...

Students learn examples of friction and drag, and suggest ways to reduce the impact of these forces. The equation that governs common frictional forces is introduced, and during a hands-on activity, students experimentally measure a...

Learners examine and observe how many human-made objects get their basic design from things in nature. They listen to the book "Nature Got There First," compare/contrast hollow bones with drinking straws, bird beaks and tool pliers, and...

Learners simulate the spread of a virus such as HIV through a population by "sharing" (but not drinking) the water in a plastic cup with several classmates. Although invisible, the water in a few of the cups will already be tainted with...

Students identify the different sources of fossil fuels. For this environmental science lesson, students research about how these impact our environment. They explore renewable energy sources that could replace fossil fuels.

Middle schoolers comprehend that inventions can change the way we live. They comprehend that many inventions start out with design flaws and are refined later by subsequent inventors and designers. Students are explained that the...

Young scholars investigate various aspects of the human body  in this imaginative Tree House Detective episode about the biological biosphere. In a series of They take measurements, analyze data, and use technology. The lessons...

Eighth graders build a structure that is able to withstand a simulated earthquake. They research earthquakes, earthquake measurement, and society's preparation for and reaction to them. Pupils build models and present them to the...

In this science worksheet, students read about the Mars Pathfinder. Students also answer 2 comprehension questions about the reading.

Students create a picture of a train. For this train lesson, students read Freight Trainand discuss the trains that they see. Students discuss what it would feel like to be a train and play a game where they pretend to be a train. They...

Young scholars locate and print samples of two different business letter formats. They write rough drafts of business letters inquiring when, where, and how math is used.

Students determine how music is produced through sound waves and how instruments produce music differently than others. They construct flutes out of straws and explore how to adjust the sound.

Students study an erosion problem which existed on the school playground from as many points of view as possible. The ultimate aim is to suggest and encourage implementation of a plan to prevent further damage to the playground.
