You don't need to be discreet about using the resource on discrete variables. In the fifth installment of a 21-part module, scholars explore random variables and learn to distinguish between discrete and continuous random variables. They...

Create a neuron frenzy as your pupils play the part of the neurons. An engaging lesson creates a human chain of neurons that pass cotton balls posing as neurotransmitters. Scholars learn about pre- and post-synapses as they complete...

Does the number of calories you eat affect the total time you sleep? Young mathematicians tackle this question by collecting their own data and making comparisons between others in the class through building scatter plots and regression...

A cell of another color is still a cell. Pupils color a cell to identify its structures in the fourth segment of a seven-segment series. Groups work together to build a three-dimensional cell membrane segment, which is combined with...

Scholars apply previously learned skills to create a functional computer program. They produce a digital assistant incorporating string commands and complex conditional logic.

Show your class how people calculated complex math problems in the old days. Scholars take a trip back to the days without calculators in the 15th installment of a 35-part module. They use logarithms to determine products of numbers and...

The road to a better understanding of engineering lies with bridges and tunnels. A set of four engaging activities teaches learners about engineering concepts related to construction projects. They perform an experiment to find the...

Explain the importance of radioactive half-life as your high school biologists demonstrate the concept by performing a series of steps designed to simulate radioactive decay. Pupils use pennies to perform an experiment and gather data....

Trigonometry, art, and Valentine's Day come together in a creative activity about parametric equations. Learners calculate several equations before graphing them either by hand, on a graphic calculator, or Excel spreadsheet to curve...

Alphabet insects! Who has ever heard of such a thing? Get ready because your class is going to research insects that start with a specific letter of the alphabet. In small groups, they'll use the Internet and reference texts to locate...

Pasta is great for cooking—and for making Ferris wheels. Aspiring engineers use an assortment of pasta types to create a functioning Ferris wheel. They keep track of the design process to refine their designs, if necessary. Let's hope no...

Objects are larger (or smaller) than they appear! Scholars use a laboratory investigation to explore the difference between resolution and magnification. The activity allows them to calculate the size of the field of view of their light...

Teams work as material engineers to create ferrofluids, whose shape is influenced by magnetic fields. The activity, which is the fourth in the six-part series, has the teams create magnetic ink and use it to write, testing it with a...

Four steps to Open Mic Night! The location, invitations, supplies, and party favors are all part of the process in planning and hosting a fun-filled gathering where scholars read aloud an original poem or one by their favorite author. 

How do engineers turn something that is readily available, like wind, into energy? Scholars create a prototype of a wind turbine and attach it to a motor. They test out their prototypes and decide on their effectiveness. They also...

Here is a worksheet that takes all aspects of quadratic functions and incorporates imaginary numbers into the problems. The problems range from simplifying to graphing and solving by using a variety of methods with imaginary and complex...

Discover the connection between redox reactions and fuel cells. Collaborative groups build a Hoffmann Apparatus that demonstrates the electrolysis of water and then convert their models into a fuel cell. They use their fuel cells to...

Don't let your brain play tricks on you! Learners test brain reaction rates while it is receiving multiple stimuli. They time each other reading a set of color words written in different colors and again when they are written in black....

Step into the role of a zoo director with several activities about animal training and running a zoo. Kids calculate the amount of food each animal needs, design a habitat for penguins, decide how to breed bottlenose dolphins, and train...

The second lesson on finding inverse matrices asks class members to look for a pattern in the inverse matrix and test it to see if it works for all matrices. The teacher leads a discussion to refine the process in finding inverses,...

Young citizens construct an understanding of urban planning in this cross-curricular unit. Covering every aspect of city development from the political, economic, and social influences to sustainable building practices, this...

How can you teach a person about technology and engineering if he has never been exposed to the tools and devices used to create and construct? Learners with visual impairments examine a number of common tools, such as hammers, wrenches,...

Represent motion with arrows and call them vectors! The lesson is a presentation that models the mathematics involved when determining a resultant vector. It addrssses motions that are parallel, perpendicular, and a combination of...

Chemistry and physics combine forces to benefit nanofabrications. Learners examine the process of wet etching in nanofabrication. Using corrosive substances such as lemon juice and Coca-Cola, they model the etching process. They then...
