Establish student-generated evaluation criteria in the form of a rubric for assessing each team's device and presentation. Scientists studying sports have paid particular attention to properties of various balls that affect their bounce. Students will integrate and apply the processes of practicing scientists by designing and constructing a device to evaluate these properties. Only the materials provided may be used to construct the device which may be placed on a table. All the balls must be released from the device.
Students measure the bounce a ball of at least four different heights from their device.
Students design a data table and record respective heights. Student teams use materials provided to design and build their testing devices. Teams will conduct preliminary tests of their devices and make necessary modifications, particularly ensuring precise measurements of the balls' dropping height and bouncing heights. Explain your thinking and test your hypothesis, if possible. Record your calculations and compare the prdicted heights with those obtained experimentally.
