Fifth graders explore geometric building blocks in the real world in order to describe the characteristics and relationships of points, lines, line segments, rays, and planes. This is the first lesson plan in a series of lessons in...

Students gain an understanding of the difference between electrical conductors and insulators, and experience recognizing a conductor by its material properties. They build a conductivity tester to determine whether different objects are...

Students explore the concept of quadrilaterals. In this quadrilateral lesson, students play with a floor tile applet to see that there are many types and characteristics of quadrilaterals including parallelograms, trapezoids, rectangles,...

Fifth graders write and illustrate books to make a class library of math term books. They utilize vocabulary associated with geometry to make their books. For example, one character may be, Mr. A Cute.

Students create and observe coacervates. In this origin of life lesson, students create coacervates by mixing carbohydrate and protein solutions. They observe the life-like qualities of the structures and discuss the origin of life.

Students solve one step linear equations. In this algebra lesson, students manipulate their variables and numbers to answer each problem. They make sure the equations stay balanced at all times.

Students examine the gold-mining industry in Africa. In this geography skills lesson, students watch "Africa: Economics and Change," investigate the challenges of working in mines, research attributes and production of gold and discuss...

Students inspect the causes and effects of earthquakes and examine how seismic waves travel. For this earthquake lesson, students determine where earthquakes happen and why, before determining how to build an earthquake resistant...

Students solve problems using ratios and proportion. In this algebra lesson plan, students analyze skittles and their different colors as they apply the properties of ratios and proportions to solve their problems.

Don't worry, this resource actually exists. Scholars learn about imaginary numbers and work on problems simplifying square roots of negative numbers. As an extension, they research the history of imaginary numbers.

Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...

Make the connection between Hooke's law and elasticity with an activity that introduces the class to the behavior of elastic materials. The resource defines stress and strain to calculate the modules of elasticity of...

Working with imaginary numbers — this is where it gets complex! After exploring the graph of complex numbers, learners simplify them using addition, subtraction, and multiplication. 

Show your math class how to use vectors in adding complex numbers. Vectors represent complex numbers as opposed to points in the coordinate plane. The class uses the geometric representation to add and subtract complex numbers and...

Students investigate diversity. In this diversity instructional activity, students look at a variety of apples in order to compare and contrast their physical characteristics. They apply the concept to people by listing how people are...

Students brainstorm the different uses of petroleum distillates. In this chemistry lesson plan, students explain the process of fractional distillation. They analyze the impact of oil extraction to the environment.

Students examine and describe the four physical systems of the Earth. Using two of the systems, they practice their writing skills and use vocabulary associated with the different types of landforms. They predict the types of shelters...

Middle schoolers add, subtract, multiply, and divide rational numbers. They find the square and the cube of numbers. They create a game incorporating computation on rational numbers. Everyone works together to write and evaluate...

Tenth graders explore parallel and perpendicular lines.  In this geometry lesson, 10th graders investigate the relationships associated with parallel lines and transversals, perpendicular lines, and the angles formed by these...

Ninth graders discuss the real number system and its' properties. In this algebra activity, 9th graders discuss rational, irrational, closure, real numbers and the distributive property of algebra. They solve problems using these...

Students use the scientific process to show that when various surfaces are exposed to similar environmental conditions, surface temperatures may vary. They examine the "urban heat island" phenomenon and analyze why it increases energy...

Don't cover up this resource — use it out in the open! Pupils learn how to cover up various parts of a linear equation in order to help solve the equation. A worksheet of problems provides practice with this skill.

Metal slinkies, coils of wire, magnetic fields, and MRIs. To determine the safety hazards of MRI machines, class members use the provided formula to calculate the magnetic field along the axis of the solenoid.

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...
