Pupils identify and define intersecting lines and vertical angles. They draw two intersecting lines and measure one pair of vertical angles. Learners will also move a line to change the angles of a figure and describe the changes in the...

Learners work in groups to conduct experiments the demonstrate the differences between static and kinetic friction. They consider how friction affects us in our everyday lives, determine the effects of weight on friction and complete a...

Students discuss the different types of tornadoes and how they form. Working in groups, they record journal entries by conducting experiments with water bottles simulating vortex formation.

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...

Young scholars are introduced to the concepts of a watershed, stream flow and water quality. This five-day plan is an excellent way to introduce students to the concepts involved. They create their own watershed using a paper bag, water...

Students examine the characteristics and types of tornadoes. They discuss how they are formed, conduct an experiment with two liter bottles, analyze data and determine mean and median, and design a house to withstand tornado-force winds

Students begin with an overview of the Earth's interior and how volcanoes form. They learn how engineers predict eruptions. In a class demonstration, students watch and measure a mock volcanic eruption and observe the phases of an...

Students visit different departments at a local hospital to see how machines help peoples such as the CAT scan machine. They build a model of such a machine that shows how patients are moved in and out of the machine.

Students determine what an anemometer is and how it measures wind speed. They decide on a place to put a wind turbine by using an anemometer. They examine the role that engineers play when using wind speed to determine a place for wind...

Students explore similar objects. They participate in a series of hands-on, multimedia and online activities to examine how the edge length affects the angle measures, perimeters and areas of similar regular polygons. Students find the...

Fifth graders study environmental changes by examining the annual rings of a cross-section of a tree trunk. They access websites to complete a worksheet on the parts of a tree. They count the annual rings on a tree slice while observing...

Young scholars observe the changes a class tree goes through as the seasons change and record observations in journals. They investigate changes in the weather, changes in the length of the day, and how that affects people. They create...

Students collect data to create different types of graphs-line, pie, and bar graphs. They use StarOffice 6.0 to create graphs.

Students view a demonstration of how groundwater flows and define several related vocabulary terms. They complete a worksheet, participate in discussion and make a poster.

Students use everyday materials (milk cartons, water bottles, pencils, straws, candy) to build a small-scale transportation device that incorporates the wheel and axle and the lever. They race their carts/trucks, measure distance, time...

Middle schoolers determine location by using the technique of triangulation. They imagine that they are out in the wilderness and have come to the top of a ridge. How can one identify the ridge on the topo map? How can one figure out...

Students participate in a series of timed relay races using their skeletal muscles. They compare the movement of skeletal muscle and relate how engineers help astronauts exercise skeletal muscles in space. They list the three types of...

Pupils investigate segments in a triangle by constructing a triangle using Cabri Jr. They construct segments within the triangle that lie on the midpoints of the triangle's sides. Learners then compare the slope of base of the triangle...

Students learn navigational techniques change when people travel to different places. They understand differences between navigation on land, water, air and in space. They explain the concept of dead reckoning as it applies to...

Learners examine how wind energy is transformed into electrical energy. In pairs, they build miniature wind turbines and measure how much electrical current they produce. They asses the importance of design and position in energy...

Students observe a model of a waterwheel to investigate the transformations of energy involved in turning the blades of a hydro-turbine into work. They work as engineers to create a model for a new waterwheel while considering resources,...

Students study the physical force of linear momentum by investigating collisions. They analyze the difference between elastic and inelastic collisions. They calculate linear momentum.

Seventh graders investigate a ratio found in nature and in numerous pieces of artwork throughout history. The lesson is cross-curricular and builds a sense of appreciation of design for students.

High schoolers investigate the relationship between angle measures and sides of a triangle and the relationships among the three sides of a triangle. The use of technology (Cabri, Jr.) allows learners to make and test conjectures as they...
