Some things are hard to resist. Small collaborative groups build circuits and calculate the voltage using Ohm's Law. Budding engineers explore the connection between the voltage across different resistors and linear...

Elasticity and viscosity. Help your class understand the similarities and differences with an introduction to viscous fluids. After describing four types of fluid behaviors: shear thinning, shear thickening, Bringham plastic,...

Explore the concept of systems of equations in two variables and use matrices to solve them. Young mathematicians enter coefficients and constants into a matrix and then solve using row reduction. Instructions on how to use the shortcut...

As part of an initiative to strengthen our young adults' financial understanding, this problem explores the cost of bread and minimum wage since the 1930s. Learners are asked to find the percent increase from each year and compare it...

Investigate the effect of false positives on probability calculation with an activity that asks scholars to collect simulated data generated by a calculator. To finish, participants analyze the probability of certain outcomes which lead...

Get into the swing of things. Pupils use a pendulum to demonstrate the conversion of potential energy to kinetic energy and back. After measuring the speed of a pendulum and compare it to the calculated theoretical speed, they...

Pairs use an online simulation to determine the epicenter and magnitude of an earthquake. Using real data about the earthquake's maximum S wave amplitudes, they then determine the magnitude. The resource provides a great career...

There's a strong chance that class members enjoy learning math through engaging games. Scholars analyze games of chance to determine long-term behavior. They learn to calculate expected value to help with this assessment.

Do you have an energy hog in your home? Individuals pick at least one room at home to determine the amount of energy the appliances consume. Using that information, pupils fill out a worksheet to determine the cost of running each...

Intended as a reference tool for US Army personnel, this application can be used in a classroom that is studying historic and current wars or as part of an outdoor education or wilderness survival course. Some of the subjects addressed...

Pupils design a fence for a backyard pool. Scholars develop a fence design based on given constraints, determine the amount of material they need, and calculate the cost of the project. 

Is it a right triangle or not? Introduce scholars to the converse of the Pythagorean Theorem with a lesson plan that also provides a proof by contradiction of the converse. Pupils use the converse to determine whether triangles with...

Discover how to find the value of an interest-bearing account. Individuals watch a video to learn how to use exponential functions to model compound interest. After the video, they complete a instructional activity of problems on...

Try not to blind anyone with science by following the safety rules. The lesson encourages scholars to form an ionic compound from magnesium and chlorine. Then they determine the empirical formula and determine the mole ratio and percent...

Bar or circle graph—which is best? Given a circle graph and a total amount of money earned, pupils calculate the amount of money in each category. Learners use the calculated amounts to create a bar graph and compare the two displays.

Witness the power of exponential growth with an activity that investigates two different savings plans. Class members create tables of values to see how and when a savings plan increasing exponentially exceeds one increasing linearly.

Pupils often wonder how we know the distance to various stars. Starting with a thought experiment and progressing to a physical experiment, they determine the brightness and distance to various stars. The evaluation requires...

Illuminated physics stars show what they know about light by taking this exam. They match several related vocabulary terms to descriptions and answer multiple choice questions about the characteristics of light, magnification, and...

Take another look at the exam. A set of questions is a different form for the 2004 AP® Calculus BC free-response question section. The questions are evenly split into calculator and non-calculator sections. Pupils use their knowledge of...

Statistics can be manipulated to say what you want them to say. Teach your classes to be wise consumers and sort through the bias in those reports. Young statisticians study different statistical reports and analyze them for...

Statistics come front and center in this unit all about analyzing discrete data. Real-world situations yield data sets that the class then uses to tease out connections and conclusions. Beginning with the basic histogram and...

Explore the mathematics of infection outbreaks with activities that ask learners to use coordinate grids to locate infected patients. They calculate amounts of ingredients for antidotes and determine which groups of people should be...

Examine an exponential growth model. Using a fractal, learners calculate the perimeters of each stage. When comparing the consecutive perimeters, a pattern emerges. They use the pattern to build an equation and make conclusions.

Many high school science courses rely on mastery of algebra skills. In an integrated chemistry and Algebra II lesson scholars review solving equations for a specified variable with a worksheet. They use common chemistry equations to...
