Joe's bike wheel is rubbing on his brakes and it's slowing him down. He heads back home and uses a wrench to widen the brake calipers so the wheel is no longer rubbing. Joe was able to

• develop a model.

• compare designs.

• design an experiment.

• solve a problem.

Your friend Shelly tells you that she has a great idea for a different kind of hairbrush. To help explain her idea, Shelly constructs a version of her hairbrush from materials she finds in her home. Shelly’s hairbrush is known as a

• prototype.

• solution.

• experiment.

• design

Jae, Seema, and Steve like to complain about the problem of constantly outgrowing their shoes. One day, they came up with a bunch of ideas on how to fix that problem by building a shoe that expands as you grow. They came up with three different ideas on how to build the shoe. What two parts of the engineering design process did this team complete?

• designed an experiment, made a model of the solution

• developed a product, tested the design

• identified the problem, brainstormed solutions

• brainstormed solutions, redesigned the solution

Your friend Mary asks you to try out the skateboard she is designing and give her feedback on it. You take it to the skatepark for 4 days and collect daily information about how it performs at the park. You give a table of recorded data to Mary, and the two of you talk about how the skateboard could be better. Then Mary makes another version of the skateboard. Which part of the engineering design cycle did you help with?

• designing the skateboard

• building the new skateboard

• testing and evaluating the skateboard

• identifying the problem

Bonnie works in a lab where she investigates microbes that cause an illness. She designs experiments with different kinds of microbes to learn how each microbe works. Based on this work, Bonnie is most likely to be considered

• a scientist.

• an inventor.

• an engineer.

• a technician.

Jae, Seema, and Steve are always arguing about who has the strongest ruler. They decide to figure out who has the strongest ruler by comparing the strength-to-mass ratio of each ruler. They place a ruler in the space between two desks (as shown below) and hang weights from the ruler until it begins to sag. Shown in the table below are the results of their investigation. According to their data, the ruler with the highest strength-to-mass ratio was

• wood

• plastic

• metal

• all the same
