Marble Ramp Trials

Students time a marble down a cardboard ramp again and again; the times never match, so they hunt for causes (a late tap, a bump, a typo) and mark outliers, then change the ramp's height and surface to see how two attributes work together.

Play style: Lab
Module: Why Data Varies: Repeat measurements, spot outliers and relationships between attributes
Grade: Grades 3-5 · Computer Science
Standards: E3-DAT-DI-10 E4-DAT-DI-10 E5-DAT-DI-10
