Innovation: Inches, Feet, and Hands

INNOVATION—INVENTION—INQUIRYTechnological Literacy Units for Grades 5 and 6Innovation: Inches,Feet, and HandsThis unit integrates the study of technology, science,and mathematics through the applicationof anthropometrics by improving the design anddevelopment of a new product.AnthropometricsInnovation:Inches, Feet, and HandsGiven aDesign Challengestudents willunderstand howInnovationare usedwith theMeasurementto design and developan improved productthat is used by humanhands and solve theI 3EngineeringDesign ProcessI 3 ~ Page 1


Conducting the UnitThere are five main topics in this unit. Each topic varies in length andscope depending on the schedule and length of the teaching time. Begineach topic with a quote about innovation. A list is provided on page 22.Note: Topics III and IV should be presented as students progress throughthe Anthropometric Design packet.Notes:Topic I: Understanding Innovation (2-3 hours)1.2.3.Have students read through What is Innovation? handout (pages 31and 32) and try to define the terms: discovery, serendipity, invention,and innovation in their own words. As a class, discuss and showexamples of each word and explain how they have had an impacton our society. See the Terminology transparencies on pages 26 and27.Have students answer the questions on the What is Innovation?worksheet. This can be found on page 33.Show students an example of an innovation timeline. The Teacher’sResources section identifies some potential Web sites on page 13.Have students complete the Innovations from the Past activity unit onpages 34 to 35. The intent of these two activities is to give studentsan understanding of how technology has influenced our society inthe past and how it may impact the future.Answer key forWhat Is Innovation?worksheet1.

The transparency“Anthropometrics” on page 28 will assist with this discussion.Explain that innovation is a process that requires keen observation,thinking, and doing.Describe an engineering design process (EDP) by using the EngineeringDesign Process transparency on page 25 and the EngineeringDesign Process Notes page on page 36. A good way to describethe EDP is to follow the Teaching Innovation section beginning onpage 6.Distribute the Anthropometrics design packet on pages 42 to 49and review it with the class. The purpose of the design packet is togive students an experience innovating a hand product by followingthe EDP. To prevent haphazard and potentially unsafe practices,students will need to follow the packet rather closely. It is importantto remember that most innovators follow such a process becausethey want to use their time wisely.Review the "Anthropometric Innovation Scoring Rubric" on page 41with the class.4.

AnthropometricsBackgroundAnthropometrics is animportant aspect of manyproducts that people buyeveryday. It is the study ofthe human form as it relatesto product design. A child’sglove must be made tothe correct size so it can fitwithout being too big or toosmall. On a larger scale,anthropometrics is usedto design car seats, hats,shoes, computer keyboards,Hand Products1. Gloves/Mittens2. Computer mouse3. Soda can (to open)4. Coffee mug5. Baseball glove6.

What criteria do they follow whenimproving an existing product? An innovator’s most valuable “tool” isthe ability to look at products and figure out ways to make them better.This is called problem solving because people look for a problem andtry to solve it. To solve technological problems we use an engineeringdesign process. With this process, anyone can design and produce anidea by following each step carefully and working slowly. This activity isdesigned to improve your problem solving abilities; specifically related toanthropometrics, measurement, and technology.An engineering design process is used to provide direction when learningto solve technological problems. As you become more experiencedusing this process you will find that it becomes more natural.Anthropometric ChallengeYour challenge is to work with a partnerto examine a product that requires theuse of someone’s hand. A sample list of“hand products” is shown in the box onthe left. Find one thing that can be done toimprove a product. Then design and makea prototype of the product and show it tothe rest of the class. Since this may be thefirst time you have done this type of activity,it will be important that you follow anengineering design process. The pagesthat follow will aid you in this process.Innovation: Improving an existing productto meet a human need or want.Design CriteriaThe anthropometric hand product must be:• Neatly constructed and safe• Designed for a target audience• Supported with sketches andwritten ideas


How Big Do You Think It Is?Name: ______________________________________________Class: __________________In the previous activity you measured your hand. In this activity, you will be using your hand to estimatethe size of different objects. Estimating is a method that is used to get a quick guess of the sizeof something. Estimating is never as accurate as actually measuring, but it is much quicker. Estimatinghelps to check if an answer truly makes sense.With a partner, use your hand to estimate the size of the following objects. Write the approximate sizein the column labeled “Estimated Size” for each person. Your answers probably will not be exactly thesame. Once all the items are estimated, go back and together measure them accurately with a rulerto the nearest 1/8” (1 mm). Write these sizes in the column labeled “Actual Size.”Item MeasuredEstimated sizePartner #1Estimated sizePartner #2Actual Size1. Length of an unsharpened pencil2. Height of your chair seat3. Width of your chair seat4. Thickness of the top of your desk5. Width of a piece of paper6. Length of a shoeAnswer the following questions:1.Explain how using your hand as a means to estimate can be a good method.______________________________________________________________________________________________________________________________________________________________2.If you were to design a new glove for a child who is 10 years old, how would you know what sizeto make it?______________________________________________________________________________________________________________________________________________________________I 3 ~ Page 39
