Explore the concept of this perfect square trinomial and difference of squares lesson. A hands-on activity that uses paper rectangles and squares to illustrate the perfect-square trinomial and difference of squares formulas.

The sky's the limit of what you create when combining functions! The module begins with a review of transformations of parent functions and then moves to combining different function types using addition, subtraction, and...

Don't let the term, "slotted wood board" detract you from the value of this experiment. Class members tie a string to a cart and, with even horizontal force, drag it up an inclined plane. The objective is to compare the work done with...

Students explain why compass angles need to be corrected for regional magnetic variation. They observe the difference between magnetic and true north. Each student measures the angle of variation for a town in a different state.

Learners observe bacteria that are able to orient themselves using the Earth's magnetic field.They comprehend the difference between anaerobic and aerobic organisms. Students can tell the difference of the shape of magnetic force field...

Work, energy, and their relationship to power: what is the common thread? Explore this with your class as they learn the concepts of work and energy, both kinetic and potential, before completing multiple practice problems to...

Middle schoolers work together to identify the accuracy of sundials. They track the position of the sun and create a shadow plot. They discover the difference between real time and clock time.

Students explore mechanical friction. They perform experiments to observe the direction of mechanical motion and the difference between rolling and sliding friction. Data results on the experiments are recorded and students answer...

An ambitious geography lesson is geared toward kindergartners. They discover what the differences are between states and countries. They look at maps of Arkansas, and learn what the shapes and lines mean. Additionally, they create a...

Your sixth and seventh graders deepen their understanding of a number line and adding integers in this concrete, hands-on activity. Learners play "Warehouse Puzzle" and then discuss their game strategies and the characteristics...

Your learners combine their knowledge of real and imaginary numbers and matrices in an activity containing thirty lessons, two assessments (mid-module and end module), and their corresponding rubrics. Centered on complex numbers and...

Discover the connection between vectors and translations. Through the lesson, learners see the strong relationship between vectors, matrices, and translations. Their inquiries begin in the two-dimensional plane and then progress to the...

Students study the concept of using a map as a tool with the usage of a balloon designed to mimic the features of the Earth with the major features marked and shown on the balloon.

Students use an inclined plane to move a heavy load.

Students explore the coordinate plane.  For this middle school/Algebra I lesson, students use dice with numbers and signs to play a game in which they must locate points on a coordinate plane.  Students work in teams to place...

Sixth graders explore how torque and work are different. In this torque lesson, 6th graders will understand the relationship between torque and work as it applies to force and distance. Students will be assessed on their conclusions of...

Learners perform translation and reflection. They identify the coordinate points of the new graph and create a formula for the movement. They identify the pre-image the and after image.

Students perform functional analysis. In this pre-calculus lesson, students recognize the different elements of a function, graph a function and analyze it. They synthesize composites of other basic functions.

Pupils convert quadratic functions from standard form to vertex form. In this algebra instructional activity, students solve polynomials using synthetic and long division. They derive and apply the remainder theorem and factor theorem.

Learners experiment with point graphs. In this math lesson, students are divided into groups and perform an experiment to see how high a ball bounces, recording their results on a point graph. Learners then answer provided questions.

Learners weigh objects using a triple beam balance. In this mass lesson, students use an inertial balance made with a metal rod to measure and graph vibrations of varying numbers of pennies in a bucket. References and discussion prompts...

Students study the conservation of energy.  For this energy lesson students explain the differences between potential and kinetic energy.

Students differentiate the properties of longitudinal and transverse waves. In this physics instructional activity, students calculate CEENBoT's rate of propagation by measuring its frequency and distance per cycle. They use a...

Students use the Pythagorean Theorem to solve problems. In this geometry activity, students solve for the distances by calculating the different parts of the shape of a two and three dimensional shape. They reason by analogy.
