Students groups act as aerospace engineering teams competing to create linear equations to guide space shuttles safely through obstacles generated by a modeling game in level-based rounds. Each round provides a different configuration of the obstacle, which consists of two "gates." The obstacles are presented as asteroids or comets, and the linear equations as inputs into autopilot on board the shuttle. The winning group is the one that first generates the successful equations for all levels. The game is created via the programming software MATLAB, available as a free 30-day trial. The activity helps students make the connection between graphs and the real world. In this activity, they can see the path of a space shuttle modeled by a linear equation, as if they were looking from above.

Students measure the relative intensity of a magnetic field as a function of distance. They place a permanent magnet selected distances from a compass, measure the deflection, and use the gathered data to compute the relative magnetic field strength. Based on their findings, students create mathematical models and use the models to calculate the field strength at the edge of the magnet. They use the periodic table to predict magnetism. Finally, students create posters to communicate the details their findings. This activity guides students to think more deeply about magnetism and the modeling of fields while practicing data collection and analysis. An equations handout and two grading rubrics are provided.

As a weighted plastic egg is dropped into a tub of flour, students see the effect that different heights and masses of the same object have on the overall energy of that object while observing a classic example of potential (stored) energy transferred to kinetic energy (motion). The plastic egg's mass is altered by adding pennies inside it. Because the egg's shape remains constant, and only the mass and height are varied, students can directly visualize how these factors influence the amounts of energy that the eggs carry for each experiment, verified by measurement of the resulting impact craters. Students learn the equations for kinetic and potential energy and then make predictions about the depths of the resulting craters for drops of different masses and heights. They collect and graph their data, comparing it to their predictions, and verifying the relationships described by the equations. This classroom demonstration is also suitable as a small group activity.

Repeated motion is present everywhere in nature. Learn how to 'make waves' with your own movements using a motion detector to plot your position as a function of time, and try to duplicate wave patterns presented in the activity. Investigate the concept of distance versus time graphs and see how your own movement can be represented on a graph.

This video presents a visual model for solving a word problem involving the multiplication of fractions. The problem asks students to use the amount of bamboo that a panda eats in an hour to determine how much he eats in a quarter of an hour if he eats at a steady rate. The video ends with a challenge problem for students to model themselves. [2:32]

This video illustrates how to use an array as a visual model for solving a word problem involving the division of fractions and mixed numbers. The problem asks students to determine the width of a rectangular fennec fox den based on its length and area. In the accompanying classroom activity, students get additional practice solving another more difficult area problem featuring the division of fractions and mixed numbers.

This video [2:31] illustrates a word problem involving the multiplication of fractions that requires students to find an unknown product based on a comparison of two quantities. One of the world's largest insects, the Goliath beetle, is known for its strength as well as its size. The animation shows a beetle lifting many times its own weight and then models how to determine the number of pounds that the beetle is lifting. In the accompanying classroom activity, students watch the video, reproduce the visualization modeled in the video, and solve a problem using a visual model. Includes teacher and student materials.

A collaboration between the National Aeronautics and Space Administration (NASA) and the CK-12 Foundation, this book provides high school mathematics and physics teachers with an introduction to the main principles of modeling and simulation used in science and engineering. An appendix of lesson plans is included.

Explore the relationship between degrees Fahrenheit and degrees Celsius. This video focuses on developing an expression to model the relationship between the temperature scales using a line graph to calculate slope and the y intercept.

Learn to identify different molecular shapes, to understand the interactions that create these shapes, and how to predict a molecule's shape given certain information about it. Explore these concepts using three-dimensional computer models and answer a series of questions to reinforce your understanding.

In this activity, students interact with 12 models to observe emergent phenomena as molecules assemble themselves. Investigate the factors that are important to self-assembly, including shape and polarity. Try to assemble a monolayer by "pushing" the molecules to the substrate (it's not easy!). Rotate complex molecules to view their structure. Finally, create your own nanostructures by selecting molecules, adding charges to them, and observing the results of self-assembly.
