Students find the different ratios of a right triangle. In this geometry lesson, students apply the concept of the Pythagorean theorem as they identify the different angles and parts of a Unit Circle. They find the ratios of sine,...

Pupils build and program a Lego Mindstorms Roverbot to travel for a given amount of time. They gather data on time versus distance traveled to determine a calibration constant for their robot, which relates time to distance.

Students study types, strength and construction of a variety of bridges. They build a model bridge and test the amount of weight it support.

Young scholars investigate how temperature and pressure cause a material to change phase. They heat water to reclaim a gas. They demonstrate that different liquids evaporate at different temperatures.

Students examine buoyancy and fluid pressure. They conduct a series of fun experiments to discover the effects of pressure and explore how pressure differences can be used to float, lift, transport, or hold a material in place.

Students explore the science of magnets and how magnets work. They conduct a series of fun experiments and magnetize objects and demonstrate how magnetism operates right through other materials.

Students examine basic electrical components. They build a simple electrical circuit which rings a buzzer. They experiment with conducting and nonconducting materials.

Students explore sound wave motion and conduct simple experiments to demonstrate how sound travels.

Students discover the different alternative fuel sources. In this biology lesson, students identify the different stages of the carbon cycle. They explain the pros and cons of using alternative energy.

Students use heart rate monitors and complete a swimming and running test. These tests allow students to obtain personal data, to manipulate the data through calculations of various parameters, and to graphically represent the data.

Learners complete cycle ergometer test to enable them to discuss their potential in each of the three events in a triathlon. They use their own dataset to make decisions as to their abilities in each sport.

Young scholars work together to design and build a paper rocket. They place a propellant in the contraption to make it fly. They discover Newton's third law of motion.

Students are introduced to basic aerodynamics through a discussion of thrust and drag and a hands-on activity. They examine the forces of thrust, drag, air pressure, aerodynamic shapes and Newton's Third Law Of Motion.

Students explore how different textures provide varying amounts of friction to objects moving across them. They build a tool to measure the amount of friction between a note card and various surfaces by measuring the distance that a...

Students discuss the importance of water in our daily lives. In this physics lesson, students calculate the pressure of water tower systems. They investigate the effect of certain variables using a computer simulation.

students analyze how oil is formed and where in the Earth we find it. Students take a core sample to look for oil in a model of the Earth. They analyze their sample and make an informed decision as to whether or not they should "drill...

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...

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 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.
