Students are briefed on Mars, NASA's goals at the planet and current analysis being completed for landing site selection. They complete a mock GIS analysis of a potential landing site by learning about their site and why it is scientifically important. Then they assess the engineering criteria to determine how safe it is and if the rover can navigate safely and efficiently. Finally, they use imagery to determine what the rover might find once on the ground and plan out a nominal traverse for the rover, including key locations for detailed study. Results of their work are presented to their peers and students try to convince the others that their landing site is the best choice.

Welcome to Statistics! In this statistics course, we learn about the ethical use and the basic practice of statistics. As we learn, we will also explore how statistics have been used unethically to create enduring and false myths about African Americans. We will also see how statistics can be used to illuminate injustice and offer clear information upon which we can act to become anti-racist agents in our communities.

Students apply high school-level differential calculus and physics to the design of two-dimensional roller coasters in which the friction force is considered, as explained in the associated lesson. In a challenge the mirrors real-world engineering, the designed roller coaster paths must be made from at least five differentiable functions that are put together such that the resulting piecewise curving path is differentiable at all points. Once designed mathematically, teams build and test small-sized prototype models of the exact designs using foam pipe wrap insulation as the roller coaster track channel with marbles as the ride carts.

GaDOE is using a new technical specification by the IMS Global Learning Consortium (IMS Global) called the Competency and Academic Standards Exchange (CASE) to enable a machine readable, linked data versions of state standards. With CASE, open-educational resources can be more easily tagged and discovered. Districts and individual educators can build crosswalks to their local learning targets, organize assessment results, and discover content through these crosswalks. The CASE format enables teaching, learning, and assessment software systems to access or consume competency frameworks and crosswalks.

This hands-on demonstration illustrates how GPS can be used to measure the inflation and deflation of a volcano. Volcanoes may inflate when magma rises closer to the surface and deflate when the pressure dissipates or after an eruption.

Students learn about the statistical analysis of measurements and error propagation, reviewing concepts of precision, accuracy and error types. This is done through calculations related to the concept of density. Students work in teams to each measure the dimensions and mass of five identical cubes, compile the measurements into small data sets, calculate statistics including the mean and standard deviation of these measurements, and use the mean values of the measurements to calculate density of the cubes. Then they use this calculated density to determine the mass of a new object made of the same material. This is done by measuring the appropriate dimensions of the new object, calculating its volume, and then calculating its mass using the density value. Next, the mass of the new object is measured by each student group and the standard deviation of the measurements is calculated. Finally, students determine the accuracy of the calculated mass by comparing it to the measured mass, determining whether the difference in the measurements is more or less than the standard deviation.

By measuring the spacing of fossil footprints it is possible to estimate the speed of the trackmaker, but only after making several assumptions based on footprint size and the behavior of a wide range of living animals. A widely applied method for estimating speed from trackways was developed through the research of R. McNeill Alexander, an expert in biomechanics. This lab is a group exercise designed to lead students step-by-step through the methods and principles involved in estimating speed of movement from trackway data using Alexander's method. First students test the method on humans to see how accurate it is, and then they apply it to measurements taken from a variety of dinosaur trackways. This activity involves having students collect speed and footprint data on subjects while they are running and walking. The footprint data are analyzed and the speed estimates are compared to the actual measured speeds. Students then collect trackway measurements from published illustrations of dinosaur trackways to estimate dinosaur speeds. Students calculate the percent error for their experimental estimates and use this to interpret the results obtained from dinosaur trackways. Spreadsheets may be used to record and carry out the calculations in the analysis. Students are asked to discuss the significance of their results to ongoing debates over the physical capabilities of dinosaurs.
