The Links Above Contain The Materials You Will Need To Calculate The S
The links above contain the materials you will need to calculate the speed of a Dinosaur using the measurements of foot size, stride length and the Alexander formula. This will allow you to demonstrate your progress toward acquiring math skills, used in everyday life, by using graphs, simple computations such as averaging scale and metric conversions and formulas, to accomplish a task. The briefing document should be read completely before starting. The Footprint Comparison document will allow you to determine from the shape of the footprints, which type of dinosaur you are dealing with by comparing the pictures illustrated on the footprints for exercise document. The dimensionless speed graph will be used once you have calculated the relative stride length. Note the graph is rotated such that the X axis is across the top and the Y axis is to your left. If you print it out, then simply rotate it so that the X axis is to the left and Dimensionless speed is at the bottom. Find the relative stride length you calculated on the Y axis; then, draw a horizontal line across to touch the diagonal line on the graph (do not use the example shown, this is just for illustration). Now read straight down to the X axis (at the bottom); that is your value for dimensionless speed. The final document, the Trackway Data Sheet, is where you will record your calculations and submit for grading.

The task involves calculating the speed of a dinosaur using measurements such as foot size, stride length, and the Alexander formula. This process requires understanding and applying several steps involving data collection, analysis, and interpretation, blending fundamental math skills with scientific inquiry. This exercise is valuable for developing practical skills in measurement, graph reading, and application of formulas, which are essential in many aspects of scientific research and everyday problem-solving. Initially, students need to gather measurements of foot size and stride length, possibly through observing footprint data or provided diagrams. The first step involves identifying the type of dinosaur by comparing footprint shapes using the Footprint Comparison document. Recognizing the footprint shape helps narrow down the species and provides context for subsequent calculations. The shape analysis is crucial because different dinosaur species had different gait characteristics reflected in their footprints, which informs the proper application of the Alexander formula and other related calculations.
Once a specific dinosaur type is identified, students will proceed to measure the stride length and compute the relative stride length. This ratio, typically stride length divided by the foot length, is key in further
calculations. Using the Alexander formula, which relates stride length to dinosaur speed, students can derive a preliminary velocity estimate. The formula considers limb proportions and stride patterns, linking biological measurements to motion. The speed calculation incorporates critical units—converting between metric and imperial systems as needed—and requires averaging or scaling measurements for accuracy, demonstrating essential mathematical skills.
Upon calculating the relative stride length, students will then use the dimensionless speed graph for further analysis. The graph, rotated such that the X-axis runs along the top and the Y-axis is on the left, visually represents the relationship between stride length ratios and speed estimates. Students will locate their calculated relative stride length on the Y-axis, draw a horizontal line to intersect the diagonal line on the graph, and then read downward vertically to find the corresponding dimensionless speed value on the X-axis. This step integrates graph reading skills and enhances understanding of how biological data can be visualized and interpreted graphically.
The final step is documenting all the calculations and observations on the Trackway Data Sheet. This record should include the measured dimensions, analysis steps, graph readings, and final speed estimate. Proper data recording ensures transparency and reproducibility of the scientific process. Submitting this document for grading not only assesses technical accuracy but also promotes scientific communication skills, emphasizing clarity and organization in presenting scientific data.
This activity exemplifies the interdisciplinary approach linking biology, mathematics, and data interpretation. It highlights the importance of measurement accuracy, the application of formulas, and the ability to analyze and interpret graphical data essential skills for students pursuing careers in science and engineering. The exercise also fosters critical thinking, attention to detail, and patience, which are invaluable traits in scientific research and real-world problem-solving scenarios.
