I used this in a unit after we have reviewed the key contributions, causes and effects, from select inventors and their inventions. After we learn about the inventors, I assign students to create their own invention. This is the engaging sheet I pass out to get their thoughts organized, and to make the sketch of invention. I have students sketch the invention, plans, blueprint, and/or ideas on the back of paper (blank).
Use the back of this chart (blank) for invention plans!
