Core Skills Analysis
Math
Brantley used math skills by comparing and measuring how different conditions changed his sand sledding results at Great Sand Dunes National Park. He thought about variables such as slope, sand texture, and moisture, which involved making comparisons and recognizing patterns in speed and resistance. As a 13-year-old, he practiced informal data analysis by noticing which runs felt faster or slower and using those observations to make better choices on later attempts. His trial-and-error approach showed that he was beginning to connect quantitative reasoning to real-world performance.
Physical Education
Brantley actively participated in a physically demanding outdoor activity that required balance, coordination, and body control. He adjusted his posture and weight distribution on the board to improve stability, speed, and steering, which showed growing awareness of how movement affects physical performance. As a 13-year-old, he demonstrated endurance and adaptability by repeating runs and refining his technique after each attempt. His engagement reflected persistence, self-regulation, and a willingness to improve through practice.
Science
Brantley explored science by observing how friction, motion, slope, and environmental conditions influenced sand sledding at the dunes. He discovered that finer, drier sand reduced resistance, while steeper slopes increased speed and flatter surfaces slowed momentum. As a 13-year-old, he practiced scientific observation by testing ideas, comparing results, and drawing conclusions from direct experience. His careful attention to cause and effect showed strong curiosity and an early understanding of basic physics in a natural setting.
Tips
Tips: To extend Brantley’s learning, have him create a simple run log with columns for sand type, slope, body position, and result so he can organize his observations like a young scientist and mathematician. He could also sketch the dune and label where friction seemed higher or lower, helping him visualize how terrain affects motion. For a hands-on follow-up, try a home experiment with a ramp, different surface materials, and a toy sled to compare speed and resistance in a controlled setting. To deepen reflection, ask Brantley to write a short explanation of which adjustment helped most and why, connecting his experience to the physics of motion and balance.
