Constructing a Working Crane

Illustration Elements


Students were asked to construct a functioning model construction crane like the ones dominating the skyline in their community.


Teacher Reflection

This student and her group researched cranes online, created a design sketch, assembled materials, developed multiple versions of the design, tested component pieces, redesigned a half-lap joint that proved too weak, and then built the crane. She incorporated a swivel scavenged from an old computer hard drive into the final design.

Creative Thinking

I can get new ideas in areas in which I have an interest and build my skills to make them work.

I generate new ideas as I pursue my interests. I deliberately learn a lot about something by doing research, talking to others, or practicing, so that I can generate new ideas about it; the ideas often seem to just pop into my head. I build the skills I need to make my ideas work, and usually succeed, even if it takes a few tries.

Critical and Reflective Thinking

 I can gather and combine new evidence with what I already know to develop reasoned conclusions, judgments, or plans.

I can use what I know and observe to identify problems and ask questions. I explore and engage with materials and sources. I can develop or adapt criteria, check information, assess my thinking, and develop reasoned conclusions, judgments, or plans. I consider more than one way to proceed and make choices based on my reasoning and what I am trying to do. I can assess my own efforts and experiences and identify new goals. I give, receive, and act on constructive feedback.
