The tension builds as learners experiment in your classroom. The 17th installment in a 24-part series has scholars investigate the concept of surface tension. After discovering characteristics of surface tension, they add a compound...

In a time of fake news, media manipulation, and Internet trolls, a resource equips learners with the tools they need to recognize and combat resources that are designed to appeal to our cognitive biases. Introduce learners to five...

Enter the world of Harry Potter and learn new vocabulary at the same time. A high-interest reading passage provides insight into the history of Harry Potter. Follow-up activities incorporate key vocabulary strategies, such as using...

Ride the wave to an understanding of refraction! The first in a series of two inquiry-based lessons challenges learners to create transverse waves with two different types of springs. As their wave hits an object, they observe the change...

Create a coat of armor for dinosaur volunteers. Young scientists explore the oxidation-reduction reaction facilitated by electric current. The result of the reaction is a dinosaur coated in copper and zinc, which leads to an...

It's gameplan time! Journalism scholars create a social media plan based upon work completed in previous lessons. The activity, fifth in a 16-part Social Media Toolbox series, focuses on using data and consensus to create an effective...

Making inferences isn't an exact science. Using data about salaries, learners investigate the accuracy of their inferences. Their analyses includes simulations and randomization tests as well as population means.

Nathaniel Hawthorne's "Rappaccini's Daughter" provides the text for an activity that asks readers to select specific passages from the story, identify the aspect of American Romanticism the passage exemplifies, and then provide an...

Find similarities in seemingly unlike organisms. The second instructional activity in a series of 12 builds the concept of a taxonomy and explores the use of a dichotomous key. Learners begin in part one by attempting to group a set of...

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...

What is the fastest way to get from point A to line l? A straight perpendicular line! Learners use what they have learned in the previous lessons in this series and develop a formula for finding the shortest distance from...

You know about the tangent function, but what are tangent lines to a circle? Learners investigate properties of tangents through constructions. They determine that tangents are perpendicular to the radius at the point of tangency,...

Time for statistics and learning to overlap! Learners examine Venn Diagrams as a means to organize data. They then use the diagrams to calculate simple and compound probabilities.

Show scholars the importance of recognizing a normal curve within a set of data. Learners analyze normal curves and calculate mean and standard deviation.

Triangles, triangles, and more triangles! In this second installment of a 36-part series, your young mathematicians explore two increasingly challenging constructions, requiring them to develop a way to construct three triangles that...

Use the resource to teach methods for solving exponential equations. Scholars solve exponential equations using logarithms in the twenty-fifth installment of a 35-part module. Equations of the form ab^(ct) = d and f(x) = g(x) are...

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...

Use context to explain the importance of the key features of a graph. When context is introduced, the domain and range have meaning, which enhances understanding. Pupils use application questions to explore the key features of the graph...

Many learners find completing the square the preferred approach to solving quadratic equations. Class members combine their skills of using square roots to solve quadratics and completing the square. The resource incorporates a...

How many points are needed to define a unique parabola? Individuals work with data to answer this question. Ultimately, they determine the quadratic model when given three points. The concept is applied to data from a dropped...

Relevance is key! The resource applies quadratic modeling by incorporating application of physics and business. Pupils work through scenarios of projectile motion and revenue/profit relationships. By using the key features of the graph,...

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...

Ours is to wonder why, not just to invert and multiply. The seventh installment of a 21-part module uses fraction models to help pupils understand why the invert-and-multiply strategy for dividing fractions works. They then work on some...

Take any number, multiply it by five, and then divide by five. Did you end up with the original number? In the same vein as the previous lesson, pupils discover the relationship between multiplication and division. They develop the...
