Find the needle on a lined paper. Pupils run a simulation of dropping a needle on a lined paper. The probability of the needle crossing at least one line is pi/2. After each trial, the interactive displays the approximation of pi based...

Are your young mathematicians having a hard time making heads or tails of probabilities? It's no toss up—here is a resource that's sure to straighten them out! Learners run the interactive to toss a coin a different number of times....

Adjust the overlap to compare probabilities. Using sliders, learners adjust the shape of two Gaussian curves. The interactive calculates the area of the left tail for one curve and the right tail for the other. Pupils set the interactive...

Control the spread of a contagious disease. An applet allows pupils to run a simulation on the spread of a disease. Rules govern how the disease is spread and the length of time it takes to recover. Learners view the spread visually and...

Teach budding mathematicians how to square a triangle with an interactive that shows a graphical proof of the Pythagorean Theorem. Pupils alter the lengths of the legs using sliders. Using the inputted lengths, the applet displays the...

Make sure the measurement is right. The interactive provides right triangles with a missing side measurement. Pupils use the given sides and the Pythagorean Theorem to calculate the length of the missing side. After entering the length,...

Slide the class into a skewed view. Learners alter the location of the median relative to the mean of a normal curve to create a skew distribution. They compare the curve to a histogram distribution with the same skewness. 

Does the size of the bin matter? The resource allows pupils to explore the relationship between the normal curve and histograms. Learners view histograms compared to a normal curve with a set standard deviation. Using the interactive,...

Explore different types of functions using an interactive lesson. Learners enter functions and view the accompanying graphs. They can choose to show key features or adjust the scale of the graph.

You'll have no regrets when you use the perfect lesson to teach regression! An interactive resource has individuals manipulate the slope and y-intercept of a line to match a set of data. Learners practice data sets with both positive and...

What does the graph mean? Pupils view 10 graphs and determine whether they are possible based on their contexts. The contexts are distance versus time and profit versus time.

Use a function to operate on two variables. Pupils look at operating with complex numbers as a function of two variables. The interactive squares the input and adds a constant to it. Learners visualize the resulting output and its...

Lead your class to construct a solar still on campus to demonstrate how water can be extracted from the soil. The power of solar energy is emphasized, as is the concept of how capillary water can be recovered and purified by using a...

Six different lessons comprise this unit on marine debris. Science, language arts, social studies, and art projects make this an ideal interdisciplinary unit. The result will be well-informed future citizens who can help make a...

Teams of electrical engineers work together to develop plans for increasing electricity to a fictitious, but growing community. They consider different sources of electricity, both renewable and nonrenewable, the cost of building and...

Assign each group of 3-4 upper elementary engineers to a different type of transportation fuel. A background information page is provided to get them started with researching their assigned fuel. Each group then produces an exhibit...

Study the impact of water pollution. A hands-on experiment and an interactive story about water pollution are the basis for the learning experience. 

Definitely for high schoolers, this lesson is an open-ended exploration of energy efficiency. Groups of two to three junior environmental engineers design an experiment to test for efficiency. They prepare a full lab report and...

Students view Elmer Holtzrichter's work Mystery Planet and discuss basic shapes and patterns. They create their own collage. and discuss the patterning they created. Students demonstrate how this pattern would sound with clapping and...

Students contribute to discussions and identify how an artist elicits a viewer's response. They use William Henry Jackson's Pawnee Indian Village, photograph and painting. After analyzing this information, students use information gained...

Fourth graders discuss early Nebraskan history. They view and discuss the painting "Sodhouse Family." Students are directed to the artistic elements of the painting, such as the horizon line. They follow a prescribed procedure to create...

Students explore, examine and study a module that focuses on the science of the oral environment and major scientific concepts relating to oral health. They investigate the process of tooth decay by interacting with stories and games...

Young scholars view and discuss the painting A Narrow Escape, by Alfred Jacob Miller. They write their own narrative about a time they were either scared or frightened. They make sketches of that time and choose one to paint using...

Students view and interpret Dan Howard's artwork entitled, Soliloquium:IV. They write a story of what they think is behind the painting and then paint their own soliloquy.
