Horizontal and vertical speeds change as projectiles move through space. As part of a series on vectors and projectiles, scholars create vector diagrams to compare these speeds at various locations. They they determine the values for...

Discover the properties of water-loving and water-hating surfaces. In the seventh installment of a nine-part series, scholars explore hydrophilic and hydrophobic surfaces by conducting an experiment. They observe surface coatings,...

Discover a new application of the Pythagorean Theorem. Learners prove and apply the converse of the Pythagorean Theorem in the 17th lesson in a 25-part series. The examples ask learners to verify right triangles using the converse...

It's not often that math allows for multiple answers. Young mathematicians identify possible numbers of triangles when given two sides and a non-included angle. An interactive helps with this investigation.

Does practice make perfect or just improvement? Scholars practice drawing a triangle on an Etch-A-Sketch. They learn about the part of the brain that controls sensory-motor integration and apply that to an analysis question.

Hands-on stations in which groups of primary learners experience what mirrors can do provide opportunities for experimenting and authentic discovery. Recording their observations in complete sentences seems age-inappropriate. Drawing...

Sharpen your pencil and grab a ruler, it's time to draw some quadrilaterals! Given the definition of a parallelogram, rectangle, and rhombus, learners draw examples and nonexamples of each figure. The three definitions are...

Compare and contrast the four types of transformations through constructions! Individuals are expected to construct the each of the different transformations. Although meant for a review, these examples are excellent for initial...

Ramp up using trigonometric ratios. After receiving a request to check school ramps to verify they meet ADA requirements, groups calculate the angle of the incline on ramps on campus. They report their findings via a letter to the...

This well organized poster shows a step-by-step algebraic proof and related graphic. Understanding how formulas were derived, connects learners to the idea that the study of mathematics is continuous and cumulative. Learners will...

After walking in a nearby neighborhood, have your class create this amazing city street pop-up. They study the facades of the buildings they see, focusing on geometric line, shape, and architecture. They then draw, cut, and create a city...

An excellent language arts instructional activity. Learners read seven sentences and determine if each is simple, compound, or complex. In order to practice sentence combining, young writers join 10 sets of sentences to form compound...

Middle and high schoolers investigate all the different places in math that square root is present. In this geometry lesson, pupils discuss square roots as it relates to a right triangle and construction. They go over altitude, rise,...

Graph equations of lines using the slope-intercept method or by plotting both x and y intercepts. Determine if two lines are parallel or perpendicular by comparing their slopes. This handout includes step-by-step directions and four...

Designed by School Power...NaturallySM, this lesson familiarizes advanced earth science and physics learners about the variables that affect our supply of solar energy. They examine gas spectra and perform calculations. There is an...

During the Battle of Baltimore in the War of 1812, only 25% of the bombs and rockets fired at Fort McHenry actually reached their target. Using an interactive online simulation, combine your historical study with physics and...

Introduce your classes to a fourth state of matter! Liquid crystals have a colorful sheen that changes based on different physical factors. Learners use this information to create a liquid crystal thermometer where the color of the...

Let the resource take center stage in a lesson on population density. Scholars use provided historical data on the center of the US population to see how it shifted over time. They plot the data on a spreadsheet to look the speed of its...

Students study elevation of the Sun above the horizon and the angle of the rays and their heating power.

Learners see application of construction techniques in a short but sophisticated problem. Combining the properties of inscribed triangles with tangent lines and radii makes a nice bridge between units, a way of using...

In this trigonometric ratios worksheet, students find the missing angle of 20 triangles by using sine, cosine and tangent ratios. Students compute the angle measurement of given ratios for six problems.

Students identify tangents, chords and secants. In this geometry lesson, students graph circles and identify angles created by secant lines, tangent lines and chords.

In this postulates and theorems worksheet, learners explore a concept map containing information about angles and sides, alternate interior angles, and diagonals of a parallelogram.  They use the concept map to prove theorems...

Students differentiate between the different properties of arcs, arc lengths, chords, and chord lengths. In this circles lesson plan, students calculate the arc length of a given circle, and find the measure of the inscribed angles of a...
