Slide2Think Tank Time
How might engineers use technology in their work?Write your answer on an index card.
DAY 1
Slide3Can you identify the steps of the engineering design process in this
Engineering Design Process
VIDEO
Slide4Grabbers/Levers
Slide5Assistive Devices
As you watch the video, think about the role that technology plays in engineering.
Slide6Technology & Communication
What types of technology could your team use to communicate with the electrical engineering team? solve practical problems.
Slide7Criteria & Constraints
Criteria--Device must:Grasp the objectMove the object Lift the object from the floor to the tableThe ratio of “forearm” length to “hand” length is approximately 1.6:1Constraints—Device must:Be built from only the materials providedBe able to grasp and lift at least one object
Slide8Grabbers/Levers
Slide9Human Levers?
A human arm is a lever. The elbow is a hinge for the long bones of the arm
How can that motion help when you pick something up?
Slide10Muscles Move the Bones
What are two arm muscles that play a role in raising and lowering the arm? Think of how might you raise and lower an artificial device.
Slide11The Right Ratio
Nature has always been admired for its patterns and symmetry.
In particular the ratio of 1.6:1 is known as the Golden Ratio and is seen repeatedly throughout the natural world.The ratio of the lengths of the human forearm to the hand is one example of the Golden Ratio.
How do you measure up?
Work with your team to measure and calculate each team member’s forearm length to hand length ratio. Record the data and use it to help make decisions about your prototype design.
Slide12Think Tank Time
List the steps of the engineering design process (EDP) your team has completed.Write what your team did for each step.Which step will your team be working on next?Write your answer on an index card.
DAY 2
Slide13Criteria & Constraints
Criteria--Device must:Grasp the objectMove the object Lift the object from the floor to the tableThe ratio of “forearm” length to “hand” length is approximately 1.6:1Constraints—Device must:Be built from only the materials providedBe able to grasp and lift at least one object
Slide14Think Tank Time
Think about the mechanical device you built on Day 2……Did your prototype work the way you wanted it to?What improvements could you make?Write your answer on an index card.
