Students imagine they are scientists or engineers designing a new space probe to explore our solar system. They choose a planet, review its weather factors, and use a rubric to gather information, make a plan, modify and/or test their plan, and create their design. Students conduct peer evaluation and revise, publish, and present their designs.
