Four is the perfect number—if you're talking about parallelograms. Scholars determine a possible fourth vertex of a parallelogram in the coordinate plane given the coordinates of three vertices. They read a conversation...

What is a chemist's favorite plant? Stoichiome Tree! Scholars produce hydrogen gas by reacting magnesium with hydrochloric acid. Then they calculate the molar volume of the gas produced before answering assessment questions. 

Building off young chemists' knowledge of the states of matter, kinetic molecular theory is the focus of the unit. Eight days of lessons including multiple demonstrations, one lab experiment, directed instruction, and worksheets,...

Parallelograms are pairs of triangles all the way around. Pupils measure to determine the area and perimeter of a parallelogram. They then find the area of the tirangles formed by drawing a diagonal of the parallelogram and compare their...

Where does the pop in pop rocks come from? An engaging activity asks scholars to measure the amount of carbon dioxide in a package of Pop Rocks candy. Learners dissolve the candy in water and use the solubility of CO2 to determine its mass.

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...

Geometric figures are perfect to use for proofs. Scholars prove conjectures about whether given points lie on a triangle and about midpoints. They use a provided dialogue among fictional students to frame their responses.

Don't think negatively about exponents. Young mathematicians dissect a fictional conversation between pupils trying to evaluate an expression with a negative exponent. This allows them to understand the meaning of negative exponents.

Expand your knowledge of exponents with an activity that promotes critical thinking and comparison skills. Middle and high schoolers compare numbers written in expanded and exponential form and explain their strategies for solving...

Math was easier before it got mixed up with the alphabet. A 10-page test covers material from multiple years of high school math. Scholars demonstrate knowledge across domains with a mixture of short answer and applied problems.

Introduce your class to the idea of magnetic fields around electrical wires with an activity that provides the information about the direction of a magnetic field around a wire carrying an electric current.

Don't let the rules overrule the lesson. Mental math steps in and helps learners understand exponent patterns. The material focuses on the introductory problems of exponents, such as simplifying expressions. Teacher guides are...

You'll never look at floor tiles the same again. An assessment task prompts learners to investigate relationships between patterns involving squares and kites to determine angle measurements. They then prove...

"Does this work every time?" We've all heard it. Now learners get to explore methods to answer that question themselves. Pupils analyze a mistake that has been made with creating a formula for multiplying binomials. They then create...

Design protection from high-speed particles. The STEM lesson plan highlights why astronauts need protection from space debris. Pupils use the design process to design, build, and test a spacesuit that will protect a balloon from a...

Create bending joints—but don't break! The activity shows how to make a puppet using straws and fishing line. Pupils create cuts to make joints that rely on the elasticity of the straw to bend and return to their original shapes.

Change the way you teach about rewriting expressions. A diagnostic task asks learners to transform expressions in different ways. Given two linear expressions and two quadratic expressions, they rewrite them into the indicated forms.

Three branches of government help create a system of checks and balances. A helpful resource provides a series of articles regarding the balance of power between the legislative and executive branches of government. Historians answer...

A two-part lesson asks young scientists to research the contributions of African American scientists at Bell Laboratories. After presenting their findings, class members watch two demonstrations that introduce them to total internal...

Stars exist from a few million years to over 10 billion years, depending on their mass. Scholars perform a play acting as stars to learn about their different life cycles. They develop an understanding of many of the fundamental concepts...

Young scholars examine the legal issues involved when there is a dispute over lunch money at school. They read the case study, discuss the two points of view, and illustrate a picture of how they would solve the problem.

Students employ a wide range of strategies as they write and use different writing process elements appropriately to communicate with different audiences for a variety of purposes. Students conduct research on issues and interests by...

Learners are introduced to the basic states of matter: solids, liquids and gases. Through experimentation, students determine that liquids and solids have definite volume, that gases do not have definite volume, and that solids have a...

Students read and respond to science fiction literature, such as that written by Jules Verne. They research characteristics of deep-sea environments and use this information to design an underwater exploration apparatus. in addition,...
