Logical thinking is at the forefront of this jam-packed lesson, with young mathematicians not only investigating geometric concepts but also how they "know what they know". Through each activity and worksheet, learners wrestle with...

Packed with visual aids and multiple learning opportunities, an engaging exercise challenges individuals as they explore the role of producers, consumers, and decomposers. After discussing differences between food chains, food...

What occurs following a natural disaster? High schoolers research this question and others as they investigate natural succession after a disaster. First, as they differentiate between primary and secondary succession, they explain...

Rather than waiting for the world to change, encourage your class members to become agents of change with a project that asks groups to select an issue found in Tyson Miller's Dream of a Nation: Inspiring Ideas for a Better America....

Encourage your young citizens to make a difference. Using Tyson Miller's Dream of a Nation: Inspiring Ideas for a Better America as a starting point, class members watch documentaries, investigate issues, and then write letters to...

What properties does area possess? Solidify the area properties that pupils learned in previous years. Groups investigate the five properties using four problems, which then provide the basis for a class discussion.

Are pyramids and cones similar in definition to prisms and cylinders? By examining the definitions, pupils determine that pyramids and cones are subsets of general cones. Working in groups, they continue to investigate the relationships...

Triangles are all about threes, and practicing proving postulates is a great way to get started. The first page of the activity provides a brief introduction of the different properties and postulates. The remaining pages contain...

Young programmers investigate the Single Source Shortest Path problem by working in paris to devise their own algorithm. They then progress to using Dijkstra's Algorithm to solve the problem. 

Class members investigate The Indian Removal Act of 1830, U.S. Theft of Mexican Territory Timeline, and President Abraham Lincoln’s letter to Horace Greeley, 1862, and then conduct a mock trial of each of these documents to determine...

Don't use an average resource ... use this one. As a middle school assessment task, learners first determine mean, median, and mode of salaries given in a frequency table. They then investigate how a change in one value changes the...

Drawing circles isn't the only thing compasses are good for. In this first installment of a 36-part series, high schoolers learn how to draw equilateral triangles by investigating real-world situations, such as finding the location of a...

How hard can it be to split something in half? Learners investigate how previously learned concepts from angle bisectors can be used to develop ways to construct perpendicular bisectors. The resource also covers constructing a...

You say that perpendicular bisectors intersect at a point? I concur! Learners investigate points of concurrencies, specifically, circumcenters and incenters, by constructing perpendicular and angle bisectors of various triangles.

Investigate the benefits of using global variables. The seventh installment of a 21-part unit continues the study of variables from the previous lesson. Young computer scientists modify two existing apps by adding variables and learn how...

Who knew the sum of a number's digits gives such interesting information? The 18th installment of a 21-part module has scholars investigate division by three and nine. After looking at several examples, they develop divisibility tests...

Primary graders become sun scientists and conduct experiments to learn about the beneficial and harmful effects of the sun and UV radiation. They also investigate their personal sunburn danger zones and learn about how to protect...

Investigate experimental design through a hands-on exploration. A creative lesson allows learners to design an experiment to monitor the effects of alcohol on the C. elegans worm. After conducting the experiment, individuals analyze...

Does the accuracy of the first guess make a difference down the line? Learners investigate the effects of the iterative process of finding roots, using Newton's Method. By moving the initial guess of a root on a graph, pupils observe the...

A change in a parameter can end in overpopulation. The resources gives pupils the opportunity to control the parameters of rabbits and wolves in a natural setting. Using the set parameters, the simulation runs and displays the population...

Why didn't the Emancipation Proclamation free all slaves? Young historians study primary source documents including Lincoln's proclamation and the 13th Amendment to the United States Constitution. Groups also investigate the three...

The Blue Man Group, three bald performance artists painted blue, offer lessons designed to engage, intrigue, and excite the imaginations of all ages of learners. Groups craft a trickster tale, invent melodious mathematical instruments,...

Microchips are a man-made wonder. Investigate the manufacturing wonder with a hands-on inquiry-based lesson. Scholars simulate the process of pattern transfer using photoresist. Their conclusion identifies how their process replicates...

Puzzle your way through to a new understanding of area. Scholars learn about the area of polygons through equidecomposability, the idea that polygons that can be decomposed into the same set of pieces have the same area. By using...
