![]() Students should compare their design concepts with the data they've collected and explain why the data matches their expected results or not.To test a design, attach a PocketLab, turn on the 3 axis accelerometer (detailed instructions below), record the peak force for 3 to 5 trials, calculate the average peak acceleration, range or standard deviation, and calculate average velocity. Have students start building and testing designs.Students should use force, velocity, time, and acceleration to explain why they think their designs should achieve the expected goal. Before building anything, students should hypothesize which design factors are important, and draw at least two or three potential design concepts.Have students draw a free body diagram and discuss the direction and magnitude of the forces on the egg.Here is how to transform the experiment to include data collection and engineering design (student worksheet is below): For an extra challenge, assign costs to the materials, and have the students track and minimize cost of their design.There is a fixed height ‘drop zone’, each lab group has a set of materials to use, and students understand the general objective. ![]() Students are working together in lab groups. ![]() ProcedureĬonduct a standard egg drop experiment, making sure: By adding data collection, an egg drop can be turned into a rich engineering design activity for the following NGSS standards: MS-ETS1-3 Engineering Design and MS-ETS1-4 Engineering Design. ![]()
