Learners consider a set of questions to determine a series of transformations that will move one figure to another. Once the series is determined, the pupil then determines whether the pre-image and image are either congruent...

Prepare your AP Physics class for the exam with a video that covers work, energy, and power. The quick review also covers common mistakes and test-taking tips that will help your scholars find areas they need to spend more time...

Help pupils review for the portion of the AP Physics exam that covers linear momentum and impulse review with a short video that covers an extensive amount of material.

Can you justify that mathematically?  Help learners see the process of solving as using mathematical properties rather than a set of steps to memorize in the fourth module of a nine-part Algebra I series. The module contains six...

The beauty in this resource is the lengthy list of highly charged, controversial-issue research topics. Categories include issues of race, politics, law, environment, education, athletics, gender, and technology. After selecting a topic,...

How can you safely model exponential growth and decay? A hands-on activity uses candies to model not only exponential decay, but also exponential growth. Exponential equations are fitted by hand and by use of a calculator...

How can you compare linear functions? The seventh installment of a 12-part module teaches learners how to compare linear functions whose representations are given in different ways. They use real-world functions and interpret features in...

Teach cube roots by building on an understanding of square roots. The third installment of a 25-part series asks learners to solve simple quadratic and cubic equations using roots. Scholars compare square roots and cube roots throughout...

Help learners get their facts in line to build and solve complicated linear equations and inequalities. Pupils build upon their knowledge of solving basic equations and inequalities to solve more complex ones. Individuals work with...

What is the typical length of a yellow perch? Pupils analyze a histogram of lengths for a sample of yellow perch from the Great Lakes. They determine which measures of center and variability are best to use based upon the shape of the...

First graders read two stories.  In this literary elements lesson, 1st graders read The Hat by Jan Brett, notice patterns of prediction, identify the setting, problem and solution and compare the story to the book The Mitten.

Fifth graders design a fraction word problem PowerPoint presentation. In small groups they complete a storyboard graphic organizer for their word problem, evaluate another group's word problem, and create a PowerPoint presentation of...

Give your learners a small taste of the business world by calculating percent error and percent increase. The resource provides several practice problems to give your mathematicians practice setting up the ratio to convert to percents....

The final lesson in the 21-part series on climate change focuses on energy solutions to the consumption problem. Using data specific to their school, pupils make recommendations, follow up on actions, and carefully track progress....

Construction leads to habitat loss and local wildlife suffers. Scholars must build a reptile egg incubation device that meets many constraints. Various experiments help them discover the chemical reaction needed to reach...

Show high schoolers there is more to quadratic functions than just formulas and parabolas. Connect the math to realistic application problems with a resource that has learners consider such situations as a ball hit in the air, the...

Is light related to insulation? An informative hands-on STEM activity demonstrates how light affects temperature. First, the class investigates how light passes through different mediums and how that relates to temperature. Then,...

More than 100 cities around the world have shifted from fossil fuels to renewable energy sources. Scholars investigate a city wanting to make this switch, but needs help determining how to make the shift. Groups consider all options,...

The United States is the world's largest producer of biofuel. During an in-class investigation, young scientists produce their own biodiesel. They burn a sample of it to determine the heat of combustion. Then they discuss the...
