        Hands-On Project Questions

        Name:

        Class:

        1.    What did you make?

        2.    Function (what does it do)?

        3.    What category, or categories, of structure does it fit into? Explain how you know.

        4.    Describe any internal forces acting on your structure and where they act.

        5.    Describe any external forces acting on your structure and where they act.

        6.    Expand on the one aspect of your project you found most challenging and briefly explain why. How did you overcome the challenge?

        7.    If you were to rebuild your structure, describe one or two things you would do differently to end up with a better final product.

        8.    Briefly describe any new hands-on skills you learned or improved upon through this project (i.e. –measuring, sawing, drilling, glue gun, using a mitre box, scroll saw, band saw, drill press, etc.).
