01 / UNDERSTAND

Here is what is happening.

A prototype is an early model used to learn about a design. For a paper pencil-holder model, stability and opening size matter before decoration. A failed test can reveal a useful change. Use a drawing or soft-paper model rather than loading a weak structure with sharp objects.

Pause. Make the idea your own.

Explain one idea to a partner, draw it or write it in your own words. Which part is an observation, an example or a question?

You can use a home language. No need to share personal experiences or finish everything in one sitting.
02 / MAKE IT YOUR OWN

Your little investigation

What you need

Paper and a pencil, or a partner to talk with. Drawing and speaking are welcome.

  1. Sketch a holder with a base, walls and an opening.

  2. Use paper strips as pretend pencils to test an unweighted model.

  3. Change one feature and explain what improved or stayed uncertain.
