At a depth of 3,000 m in the ocean, the pressure is 300 times that at sea level! In the activity, individuals predict what will happen to Styrofoam cups submerged 3,000 meters into the ocean. They then convert these units to soccer...

Question: What do rectangles and bathtub volume have in common? Answer: Linear equations. Learn how to identify situations that have constant rates by examining two different situations, one proportional and one not proportional.

Play a game of capture the points. Young scholars receive a number line with specific points graphed and must write an inequality that captures all the points. The second task of the algebra project is to write an inequality with...

Go for a walk in the mall. Pupils find distances between stores on a diagram of a mall on Quadrant I. The scholars also determine the midpoint between a store and an entrance to the mall to then create their own paths and determine their...

Artists working in different media often explore the same themes—to model how these same themes weave their way through different forms of artistic expression, scholars analyze images by Dorothea Lange, identifying key themes in her...

This resource is part of a three-activity unit that introduces your class to the concept of popular culture and the role that it plays in their lives. Here, learners examine the importance of the music industry and music videos in pop...

Keep track of your sixth graders' mastery of the Common Core math standards with this practice assessment. Taking a different approach than most standardized tests, this resource includes not only multiple choice questions, but also...

Young scientists find out what makes amphibians such unique and interesting animals in this simple life science lesson plan. After looking at pictures and discussing the characteristics of amphibians, learners complete a...

Proving triangles are similar is often an exercise in applying one of the many theorems young geometers memorize, like the AA similarity criteria. But proving that the criteria themselves are valid from basic principles is a great...

Solving systems of equations underpins much of advanced algebra, especially linear algebra. Developing an intuition for the kinds and descriptions of solutions is key for success in those later courses. This intuition is exactly what...

Ever sigh when learners ask why they have to know so many different forms of the quadratic equation? Here is a lesson plan that comes in handy! Using hands-on matching activities, quadratic equations are...

Introduce gas laws using the popular topic of SCUBA diving. This activity makes a connection between the gas laws and the effect of pressure and temperature changes during diving. Young engineers complete introductory experiments to...

Buying a new sofa? Learn how to use the Pythagorean Theorem, as well as algebra and graphing techniques, to determine whether the sofa will fit around a corner (which I'm sure you'll agree is a very important consideration!).

Once you know how to graph y = b^x, the sky's the limit. Young mathematicians learn to graph basic exponential functions and identify key features, and then graph functions of the form f(x) = ab^(x – h) + k from the function f(x) = b^x.

Our bodies have some amazing capabilities, but there are some limitations. Explore the limitations of the human eye through the eighth lab activity in a series of 12 biology lessons. Individuals measure their own peripheral vision...

Two teams—the environmentalists and herons—play four rounds of the game, Oh Heron. Using hand symbols to represent food, shelter, and water, players locate their match to produce more herons while those unmatched decompose. 

It's not just any circle—it's the unit circle. The fourth lesson in the series is an introduction to the famous unit circle. While working through a series of activities, young scholars learn the components of the unit circle and how to...

How do we know where we are in the world? A presentation for middle schoolers explains absolute location and other geography terms such as relative location. It also gives scholars the opportunity to practice finding absolute location on...

Developing a positive self-concept can sometimes be a challenge. Seventh graders engage in an activity that helps them identify their individual strengths and helps them recognize how these strengths can contribute to being a successful...

Emerging biochemists more fully understand the flow of energy in ecosystems as they explore the laws of thermodynamics and relate them to energy transfer in food chains. They also investigate heat loss from the human body and how...

In the 16th lesson in the series of 32 the class uses the concept of complex multiplication to build a transformation in order to reflect across a given line in the complex plane. The lesson breaks the process of reflecting across a line...

The second day of a two-part lesson on motion introduces the class to circular motion. Pupils learn how to incorporate a time parameter into the rotational matrix transformations they already know. The 24th installment in the 32-part...

What do those points on the graph mean? The 10th instructional activity in a series of 22 presents proportional relationships as graphs. Class members interpret various points of the graph — including the origin — within the context of...

Don't feel negative about negative numbers. Individuals extend their knowledge of positive numbers and fractions to rational numbers. They learn how to represent negative rational numbers on a number line, understand opposites and...
