Core Skills Analysis
Mathematics
Bella counted how many balls she placed in each cardboard tube and recorded the number of rolls each ball made. She measured the distance each ball traveled by using a ruler and noted which ball went the farthest. By comparing the lengths, Bella practiced ordering numbers from shortest to longest and added the distances of multiple runs to find a total. She also used simple subtraction to see how much shorter one ball’s travel was compared to another.
Science
Bella observed how different balls rolled through the tubes, noting that heavier balls tended to travel farther than lighter ones. She experimented with gravity and friction, seeing that smooth surfaces allowed balls to move faster while rougher tubes slowed them down. Through trial and error, Bella formed cause‑and‑effect predictions about which ball would win a race. Her observations introduced basic concepts of motion, force, and energy transfer.
Design & Technology
Bella built a simple racing track by cutting and joining cardboard tubes with guttering pipes, deciding where each piece should go to create a smooth path. She tested the first design, observed the results, and then adjusted angles or lengths to improve speed. By selecting materials and assembling them safely, Bella practiced planning, problem‑solving, and iterative design. The activity let her experience how engineers prototype, test, and refine a product.
Physical Education
Bella used her whole body to set up the track, lifting and positioning the tubes, which helped develop her gross motor coordination. While rolling the balls she practiced timing, hand‑eye coordination, and the ability to judge speed and distance. She also experienced friendly competition, learning how to cheer for herself and stay focused during each race. The activity supported her balance, strength, and spatial awareness.
Tips
Encourage Bella to create a prediction chart before each race, writing down which ball she thinks will travel the farthest and why. After each trial, have her graph the results on a simple bar graph to visualize differences and discuss patterns. Extend the project by introducing ramps of varying steepness or adding obstacles, turning the experiment into a mini engineering challenge. Finally, connect the activity to storytime by reading books about inventors and forces, then ask Bella to design her own “ultimate race track” using recycled materials.
