Core Skills Analysis
Mathematics
Jeremy used measurement and comparison skills when he measured the height of the free-standing paper towers with string. He compared structures to see which designs reached higher while still staying upright, which showed him that numbers and measuring tools can help test ideas in a fair way. He also used mathematical thinking again in the Cartesian Diver activity when he chose to use 3 split pins, making a practical decision based on how the diver needed to balance and sink. These experiences helped Jeremy connect measurement, comparison, and problem-solving to real results.
Science
Jeremy explored several science ideas through hands-on experiments. He tested plant growth by labeling three lettuce plants and watering them with water, juice, and milk, while thinking about nutrients and water content and predicting which liquid would help the plants stay healthy. He also investigated motion, forces, and engineering by building a rubber band-powered vehicle and revising it to improve traction and distance, and he learned about surface tension, chromatography, and gas density in the Magic Milk, chalk chromatography, and Cartesian Diver experiments. Jeremy showed strong scientific curiosity, careful observation, and persistence, especially when he successfully made the Cartesian Diver work.
Tips
Jeremy could deepen his learning by keeping a simple science journal for the lettuce experiment, recording daily changes, drawings, and short predictions about which liquid is helping most. He could also compare different tower designs by changing only one thing at a time, such as base width or number of folds, to see which design is strongest. For the vehicle project, he could test different wheel sizes, surface materials, or rubber band twists and then graph which version travelled the farthest. To extend the chemistry activities, he could try a new chromatography test with different markers or an extra Cartesian Diver challenge using a different number of split pins and explain the result.
