Discussion Prompts

Observing

• Which parts of the Pantograph build are important for it to create scaled drawings?
• If you move the tracing attachment to the left, which direction does the pen attachment go? What happens to your drawing?
• Were your larger and smaller drawings equally accurate, or was one better than the other? Why do you think that is?

Predicting

• What other things could you create scaled drawings of using the Pantograph?
• If the beams of the Pantograph were twice as big, do you think the scaled drawings would be larger or smaller?
• If you were an architect in charge of designing a new house, how could you imagine using the Pantograph?

Collaborating

• How did your group work together to build and use the Pantograph?
• Were there any difficulties that you worked through together? What strategies did you use to overcome a challenge?
• What is something that worked well for your group today that you can apply to future group work?
