Students investigate what causes electrical circuits to work. They construct a wire circuit and pass a paperclip through the maze, trying not to touch the wire, and answer discussion questions.

Students explore concept of current in electrical circuits. They examine how energy from the sun can be used to power everyday items, including vehicles.

Students discover the types of stress that materials undergo. They examine how bridges and skyscrapers are built to withhold the tension. They create their own structure out of marshmallows and spaghetti.

Students investigate the history of the waterwheel and common uses for water turbines today. They construct an experimental waterwheel using a two-liter plastic bottle, measure the rate of revolution of a waterwheel, and complete a...

Learners explore different levels of permeability and compare the permeabilities of several different materials. They are introduced to the basic concepts of building design, landscape architecture, and environmental pollutant transport....

Students research the demands or limitations on Earth scientists. In groups, they design and build a model that would be useful to them in the lab or field. They share their model and their ideas behind it to the class and answer any...

Students identify the radius and diameter of a circle. In this geometry lesson, students calculate the volume and area of a cylinder and circle. They relate the circumference of a circle to Pi.

Young scholars apply the Unit Circle to solve ratios of triangles. In this geometry lesson, students derive the different ratios of a triangle using the Pythagorean Theorem. They find the angles of a unit circle using a right triangle.

Students work together to identify the accuracy of sundials. They track the position of the sun and create a shadow plot. They discover the difference between real time and clock time.

Students demonstrate how to take bearings using a compass. In pairs, they select objects in the classroom then write down its first initial and bearing. They exchange papers and try to disciver their partner's object.

Students study about chromatography, a process used to separate mixtures.

Students discuss ways to make homes more environmentally friendly. They comprehend ways to reduce home resource consumption, such as passive solar heating, insulation, and geothermal heating and cooling

Students use data from real-life models to calculate and compare the force required for an airplane of a given weight to become airborne. They use a graphing calculator to evaluate data and use the World Wide Web to access data.

First graders study the basic needs of animals and compare them to human needs. They make bird feeders using milk carton and pine cones. They review the basic needs of food, water, air, and shelter and discuss what happens when animals...

Students carry out a series of experiments using self-locking plastic baggies. Each experiment demonstrates a phenomenon or principle of biotechnology.

Students discover the relationships between minerals, crystals and gems. They bring in rocks that they find at home, in the schoolyard, etc. and examine them and attempt to identify them. They set up a classroom exhibit that includes all...

Students explore the concept of ecological footprints. In this environmental stewardship lesson, students calculate their ecological footprints and consider how to reduce them.

Students identify the harmful and beneficial effects of bacteria. In this biology lesson, students test the effectiveness of antibacterial cleaners. They create a presentation based on researched information and experimental results.

Students explore human discovery by reading historical stories in class. In this inventors lesson, students define the terms scientist, invention, inventor and discovery before discussing the many differences between them. Students read...

Pupils experiment using a compass for navigation and consider how various instruments affect how we travel.

Students learn the geography of Japan and its location in reference to the United States.

Students use a NASA website do activities which help them better explain how air temperature and kinetic energy are related to aircraft propulsion.

Second graders make weather observations and record data. They use the internet to get data on the weather. After 5 days students predict the weather for the next 3 days.

Students work together to complete a 757 Glider kit. They use a GPS to discover how it operates in all weather landings. They complete different obstacles with the glider as well.
