Up, down, back, and forth. When you make a pendulum out of a spring, there's a lot to observe. Aspiring masters of motion examine the combined kinetic energies of spring and pendulum motion using a detailed interactive. Learners observe...

One-to-one means the answer is simple, right? Given four graphs, pupils use a vertical line to test each graph to find out if they are one-to-one. By using the resource, learners realize that not all one-to-one relations are functions....

Ramp up a design challenge. Class members design ramps to meet a client's requirements to comply with the American with Disabilities Act. The scholars create a scaled graph of their designs and determine the equations of the lines on...

Students gain an understanding of the concept of Diaspora relating to Greeks. They use guided discovery to apply the geographic inquiry model to an examination of the reasons for Greek Diaspora.

Delve deep into a Greek roots study with this graphic organizer. Scholars identify and define everyday words that are made from the Greek roots ast, bio, geo, and graph. 

There is zero reason not to use the resource. Given a graph with a polynomial function and a linear function, scholars move the line in an interactive. To wrap up the lesson, they note how zeros and intersection points change.

Looking for an out-of-this-world volcanic activity? Geologists study Earth's volcanic history and the neighboring planet Mars by modeling volcanic eruptions, lava flows, and building a shield volcano. Participants use graph paper and...

There's snow much to learn! Excited individuals use real-world data to discover how latitude affects the odds of a snow day. Scientists compare latitude, solar radiation, and temperature using NASA data for several locations....

Investigate what is pushing on us. An intriguing lesson has pupils calculate the amount of force on various squares due to air pressure. Using the data, individuals create a graph in the third lesson of the Up, Up and Away unit...

Many have played with seed helicopters at one time or another. Learners use paper to create their own helicopters to model the Linden seed. After a discussion of seed dispersal, they take their models outside, let them go, and make...

Diminishing habitats is a real concern that is threatening endangered species. Learners examine these concerns by studying the prairie chicken. Groups get a card with characteristics and threats to the species that they turn into skits.

After considering the role that gasoline plays in our lives and our dependence on it as a society, learners participate in a reading activity discussing why oil prices are increasing. They will then simulate being members of a committee...

Study diffraction patterns using CDs and DVDs! Scholars measure the diffraction patterns of a light wave as it hits a CD or DVD. Using the information, they can measure the distance between the tracks. 

Add some zing to your swing! Explore pendulum motion through an engaging interactive. Physical science scholars specify the pendulum's mass, rod length, and starting angle before they observe the resulting angle graph.

Put a squeeze on a sequence. An interactive provides a graphical display of a sequence. Using the graph, learners determine the algebraic expression for the sequence. Pupils use the general definition of a limit of a sequence to find the...

What variables change heart rate? Young scientists observe the beating heart in Daphnia to understand these variables. They make changes in temperature, chemicals, and other factors as they graph the heart rates. Analysis questions help...
