Product Details

Put some STEAM into your STEM curriculum! Add art to science and engineering concepts with this creative activity. The lab begins with an introductory activity in which students discover the law of levers by balancing different numbers of washers on either end of a ruler. The results guide students to design a three-tiered mobile. Once the theme of their mobile is chosen and the objects to be balanced are constructed, students weigh each object and predict the location of the center of gravity for each level. A sketch of their design is drawn and then the construction begins! Will the mobile be in perfect equilibrium? Additional learning takes place as students consider sources of error and make necessary adjustments. Soon your classroom will be filled with wonderful works of science, technology, engineering, art and math!

Complete for 30 students working in groups of three. A support stand and ring clamp are recommended 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-ETS1-4. 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
