Product Details

Set those marbles and minds in motion with this STEM Design Challenge! The Marble Down activity familiarizes students with the exciting world of engineering design. Students practice the design process by asking questions, defining problems, planning, creating, testing, evaluating and more! First, students investigate variables to determine how each affects the marble’s speed along a rubber band track. Watch students’ engagement increase as they apply the concepts from the introductory activity to build a marble maze with the longest run time.

A timer or stopwatch is required for each group and available separately.

Performance Expectations

MS-ETS1-2. Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
MS-ETS1-3. Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.
MS-ETS1-4. Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.
HS-ETS1-2. Design a solution to a complex real-world problem by breaking it down into smaller, more manageable problems that can be solved through engineering.
MS-PS2-2. Plan an investigation to provide evidence that the change in an object’s motion depends on the sum of the forces on the object and the mass of the object
HS-PS2-1. Analyze data to support the claim that Newton’s second law of motion describes the mathematical relationship among the net force on a macroscopic object, its mass, and its acceleration.
