Students solve and graph linear equations. In this algebra instructional activity, students collect and plot data on a coordinate plane. They use the CBL and TI calculator to graph systems of equation.

Students identify the properties of a circle. In this geometry lesson, students relate properties of diameter to sections of a pizza. They calculate the measure of an arc and missing angles.

Young scholars 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 distinguish between natural and man-made radiation. They measure radiation using a Geiger counter and investigate footprints of radiation.

Students investigate, describe, and predict the effects of parameter changes on the graphs of exponential functions; describe limitations on the domains and ranges of these functions; and examine asymptotic behavior.

Students investigate the history of the computer. They explore who invented the computer, how it was invented, and how it has evolved. Students work together in order to gain the knowledge need to repair computers.

Second graders investigate the meaning of temperature. They determine what happens to a thermometer when the temperature rises or falls. They place thermometers in different classroom locations in order to compare the temperature in a...

Students investigate the properties of lines and congruent triangle theorems as well as apply geometric properties and relationships to real-world mathematical problems. Given two different scenarios, they examine maps that have been...

Students evaluate the friction of tennis sneakers and redesign them to increase friction. In this physics lesson, students calculate starting, sideways and forward stopping friction. Using quantitative data, they prove that redesigning...

Young scholars investigate polygons and construct ferris wheels. In this geometry lesson, students create a circle and differentiate properties of circles and polygons. They compare the relationship between angles and circumscribed...

Students investigate the properties of quadrilaterals. In this geometry lesson, students solve problems dealing with construction and designs. They work with quadrilaterals, midpoints and parallelograms.

Pupils investigate the relationship between fractals and sequences. In this geometry lesson plan, students build a fractal tree. They investigate different career fields where fractals are used in the real world.

Students write equations of a line. For this algebra lesson, students investigate the assassination of JFK through linear equations. They calculate the length of given line segments.

Students collect information and use a line to represent it. In this algebra lesson plan, students investigate real world data to see if it makes a line. They graph the line comparing the relationship of the x axis with that of...

Students investigate tips for calculating math problems mentally.

Ninth graders test water in a local creek using chemical kits and probes. They take GPS readings and digital photographs. They calculate the Water Quality Index and create a spreadsheet.

Students research using a variety of materials and technology. They explain the specifics of growing crops. They use mathematics in common business calculations.

Students investigate how much energy is used during different athletic activities. They conduct Internet research to obtain information on the top three athletic sporting events from around the world, and calculate the calories burned...

Students investigate the probability necessary to win the lottery. They view a PowerPoint Presentation, evaluate combinations, calculate lottery probability, conduct analysis of a fair game, and design a lottery to meet various...

Students investigate the force of compression and how it acts on structural components through a hands-on group project. They use everyday products such as paper, toothpicks, and tape to construct a structure that will support the...

Students explore physics. They investigate the strategies used by an engineer to solve a problem. Students construct various models to solve the problem. They display their solutions and explain how they solved the problem.

Middle schoolers study the basic concepts of the Global Positioning System and how it increases the accuracy of navigation. They examine trilateration and how the speed of light is used to calculate distances.

Students investigate how Global Positioning Systems work and how and why GPS receivers make errors. They graph data points and apply estimation and prediction to real-life GPS situations, discuss time delay, and complete a worksheet.

Ninth graders measure the insulation properties of different fabrics by immersing cans of water covered with fabric "socks" in an ice bath and measuring temperature changes. They then calculate heat loss and graph the data individually.
