After learning about the properties of waves, students were given the following group engineering assignment: 1) Create an affordable seismograph that will record an earthquake's amplitude and wavelength. 2) Use only the materials provided 3) Work as a team 4) Plan and present their prototype, shaking the table gently for 10 seconds to simulate a light earthquake.
They were given the ability to research questions that they developed as a team, but other than that, were given no examples of a seismograph.
Their ability to invent and create always amazes me!
