Nanofibers can be made through electrospinning or force spinning in order to reduce the negative impact on the environment. Pupils study the role of fibers and dye on the environment through a series of five hands-on activities. Then,...

Get your classes moving and practicing sequences at the same time! Learners move about the room solving problems and finding their solutions. Problems include both recursive and explicit formulas and both geometric and arithmetic sequences.

Seventh graders create and perform a skit that demonstrates their conflict resolution skills. They begin by examining the process of crafting a performance and review what they have learned about conflict resolution. Next, they...

Graphing all kinds of situations in one and two variables is the focus of this detailed unit of daily lessons, teaching notes, and assessments. Learners start with piece-wise functions and work their way through setting up and solving...

Looking for an easy way to give your class experience with acid-base chemistry outside the lab? Try a detailed interactive that puts them in total control! Young chemists determine the dissociation constant and concentration of an...

How do you engage pupils in a discussion about osmosis without leaving them overwhelmed? By providing them with the tools to perform an exciting experiment, and they will see osmosis in action! Young chemists and biologists use...

Why do the bases in DNA pair up the way they do? Unravel the mystery of the double helix in a virtual lab. Young scientists follow in the footsteps of Watson and Crick to determine the free energy associated with DNA base pair binding....

Your learners will enjoy playing a game as a motivator to learning and remembering the adding and subtracting of fractions.

Bystander or upstander and advocate? Three lessons have high schoolers investigating data about bullying and school safety. Participants then learn how to take a stand against bullying and use what they have learned to create a PSA to...

Let's see how complicated we can make this simple task. The last activity associated with a 10-part series has groups design and build a Rube Goldberg machine. Teams determine a simple task to accomplish and use the engineering design...

Learners demonstrate their knowledge pictorially, concretely, and abstractly in this unit meant to last three hours over three days. Using hands-on activities, manipulatives,  real-world applications, and problem...

Use mathematics to show your classes the power of a good model. Young mathematicians analyze the famous Ponzi pyramid scheme using an exponential pattern. They make conclusions on the reliability of the plan and why it is illegal. 

As part of a study of percent and percent change, learners first complete an assessment task with several percent change problems. They then complete an activity using cards to create a diagram expressing percent increases and...

Identify the identity. Learners first solve equations to find the number of solutions. Scholars then determine if given equations are always, sometimes, or never true, leading to the concept of identities.

Transform your learners into master geometers with an activity that asks them to first complete an assessment task drawing the result after transformation of a given shape in the coordinate plane. They then use cards to...

Parallel parking might be difficult, but finding parallel lines is fairly simple. In this lesson plan, learners first complete an assessment task involving parallel and perpendicular lines in the coordinate plane. Individuals then take...

Looking for a valuable resource on the spread of infectious diseases? Here is a lesson in which pupils simulate the spread of diseases and learn about how to prevent them from spreading. Class members read case studies about diseases,...

Learners make predictions and draw conclusions from given information as they learn the meaning of probability in this vocabulary-rich, integrated activity that presents a variety of teaching strategies to motivate and reach...

Airline mechanics must be precise, or the consequences could be deadly. Their target ranges alter with changes in temperature and pressure. When preparing an airplane for flight, you must read a maintenance graph. The second lesson of...

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...

Space, the Final Frontier. The nine NASA-created challenges in this unit are designed to teach class members the engineering design process. Each challenge comes with teacher and student pages that can be used individually or as a...

Turn your classroom into a music studio as groups work together to determine why music sounds different when performed live versus a recording. After listening to some different music, each group picks a poem, creates a recording, and...

Linear equations are the focus of activities that ask learners to first complete a task that involves interpreting algebraic expressions and solving linear equations. They then take part in a card activity matching...

Science, technology, and math come together in this one combination exercise. Analyzing the common soda can from both a purely mathematical perspective and a scientific angle allows for a surprisingly sophisticated comparison of...
