Does the accuracy of the first guess make a difference down the line? Learners investigate the effects of the iterative process of finding roots, using Newton's Method. By moving the initial guess of a root on a graph, pupils observe the...

Learning about tangents doesn't have to be a slippery slope. Pupils drag a point around a unit circle to see how angle affects the slope of a line. They individually answer a set of challenge questions to come to the conclusion that...

Explore a geometric sequence model through a simulation. Learners change the starting drop height of a ball and watch how the heights of following bounces change. They consider the ratio of the consecutive bounces as they analyze...

Hyenas normally hunt alone, however scientists discovered that in Israel, hyenas hunt with wolf packs. When relationships develop between different species, we call it symbiosis. The videos teach about the three types of symbiosis and an...

Some molecules move through a membrane with diffusion while others require protein channels. The video and interactive discuss both types of passive transport. Challenge questions allow scholars to demonstrate their understanding.

How much negative feedback does a body get daily? The interactive walks through one negative feedback loop, increasing body temperature. Then it challenges scholars to relate this to mechanical feedback loops and disorders that prevent...

Do predators look for different things in different seasons? The quick interactive shows how some species survive longer in one season than another based on the conditions. The challenge questions encourage pupils to demonstrate that...

An interactive challenges mathematicians to round large numbers with help from a large scale that measures the weight of a blue whale. The practie's five questions include multiple-choice, fill-in-the-blank, true or false, and an open...

A soccer-themed interactive challenges mathematicians to solve five questions involving percent equations. Question types include multiple-choice, fill in the blank, true or false and a discussion. A color-coded stadium with movable...

Challenge your class with these essay questions based on Percy Bysshe Shelley's poetry. This resource includes 3-8 short answer and essay questions for each of 9 different poems by Shelley. Pick and choose the poems you would like to...

Informational text about the Civil Rights Movement challenges young historians to prove their reading comprehension skills with six multiple choice questions. After answers are submitted a new screen displays a score,...

Shockingly, wasps sometimes challenge lions as the king of predators! Learners explore the life of a wasp in an interactive online lesson. They read about the characteristics of wasps and then complete activities to learn about their lives.

An interactive practice challenges scholars to read an informational text and answer 10 questions. The topic of the passage is the American Revolution.

In this addition worksheet, students write partner numbers on each side of a domino, then write the total and the addition equation another way. Students then complete a "write about it" question.

In this related problems worksheet, students read a word problem, then solve a series of questions relating to it. Students then write a word problem and an equation to solve.

For this numbers worksheet, students count hats in one column and match them to their corresponding number in a second column. Numbers 1-5 are used.

How can an object as heavy as an airplane fly? Turns out the answer is quadratic! Your classes explore the Bernoulli Effect through an interactive graph representation. As a plane increases in speed, the lift force also increases. Young...

Who wouldn't want to wear four pairs of sunglasses? Each pair of sunglasses reduces the percent of incoming light by one-half. An interactive tutorial helps young mathematicians build a graph that models this scenario. They...

Can natural disasters alter natural selection? The interactive explores this concept with mice living through a forest fire. As the environment changes, the camouflage also changes. How does this one disaster impact future generations?

Can human activity influence the colors of moths? The simulation explains how pollution changed the color of tree bark, which led to the survival of a different variation of moths. It also discusses the shift back as air quality improves.

Before iPhones and calendars, how did humans determine the seasons of the year? Middle school scientists discover how to use shadows to determine the time of year in an enlightening interactive. Pupils manipulate the sun and examine the...

Does the value exist? The interactive allows pupils to visualize the Intermediate Value Theorem. Using the visualization, individuals respond to questions using specific values and general values. The class comes to the conclusion what...

How can you determine the rate of change on a curve? Pupils use the interactive to discover what happens with the average rate of change as the point move closer to the other. Using the definition of the derivative, learners find that it...

Have you ever stretched out a Slinkie so much it wouldn't go back to its original shape? Slinkies, like all springs, follow Hooke's Law. A simulation uses springs and masses to demonstrate kinetic, potential, and thermal energy. It...
