All students will have continued work in their Inventor’s Logs with preliminary models of specific inventions. Invention is a necessary activity in every society and in every economy. Inventors continue to invent and re-invent to come up with better solutions. How do inventors evaluate and improve their and others’ inventions? Modifications Assessment Materials/Resources/ Technology You may use any commonly used material to use as a primer for brainstorming improvements. You may incorporate the SCAMPER activity into the lesson. For older students, have them review each other’s designs and provide constructive suggestions for improvement. Review the students’ drawings of their modifications of the ketchup packets with labeled parts and their explanation and reflection for evidence that they understand this part of the invention process.
