Engineering is Elementary is a rigorously researched,

classroom-tested curriculum that increases students’ interest in

and confidence about engineering. EiE is designed to encourage

all children—including those from underrepresented groups—to

envision themselves as potential engineers.

EiE’s 20 units present fun, engaging engineering challenges that

allow students to apply science knowledge in meaningful ways.

Each unit is introduced by a storybook about a child who solves a

problem through engineering. Set in locations around the world, the

storybooks integrate literacy and social studies—and provide context

and meaning for the hands-on activities that follow.

Comprehensive, Teacher-Tested, EconomicalThe EiE curriculum consists of three components: teacher guides,

storybooks, and materials kits.

Teacher guides include background content, four detailed lesson plans, and duplication masters for student handouts—including planning and data collection sheets as well as reflection and assessment sheets.

Background content includes learning goals, related scientific and social studies knowledge, information on alignment with common science curricula and national standards, and a unit-specific vocabulary list.

Materials kits with supplies for 30 students are available for each unit. These kits were designed to include commonly available supplies, and materials lists are published in the teacher guides and online for those who prefer to create their own kits. (Refill kits that include consumable items only are also available.)

Storybooks introduce each unit with the tale of a child somewhere around the world who solves a problem through engineering. The books integrate literacy and social studies into the unit and illustrate for students the relevance of STEM subjects.

As they walked up to the huge model of the

Tyrannosaurus rex, Tanya pointed out the sharp, pointy

wedges that he had for teeth.

“I wonder if dinosaurs could dance.” Aisha giggled.

“I think the Tyrannosaurus rex would dance like this.” She

puffed up her chest and rocked back and forth with big,

lumbering steps as Tanya and Malcolm laughed.

They moved on to the baby chick incubator where

several chicks were about to hatch.

“So, Aisha, you were inspired by the dinosaur,” said

Malcolm. “Do the little chicks give you dance fever too?”

A Visit to the Museum of Science

Machines like this are designed to

make a simple process complicated,

using as many steps as possible!”

“It’s more fun this way. Look at

how many cool steps it takes to move

the little balls around,” said Tanya.

She watched the ball move from the

bottom of the machine to the top by

taking a ride on a corkscrew.

“I see a lever and wheels and

axles, too,” Aisha said. “We’ve barely

gone inside the Museum and we’ve

already found all kinds of simple

machines. I bet we can find more!”

she said, pulling Malcolm’s hand.

Part 3: Activity

1. Display the transparency of The Engineering Design

Process {4-1} or {4-2} and point out the “Improve” step

of the Engineering Design Process. Ask students:

♦ Why do you think this step is important?

♦ What information do you already have that might

help you figure out how to improve your subsystem

design? Data from testing our first subsystem design,

especially which parts of the design did not work very

well, what we learned in Lesson 3 about the different

simple machines and about ergonomics, etc.

2. Working in their groups, give students time to brainstorm

improvement ideas for their subsystems. If a group’s first

subsystem design was successful, encourage them to think

of ways to make their total score even lower. If groups

wish to swap simple machines, that is fine as well.

3. Have each student complete Engineering Design Process:

Improve! {4-7}. Remind them to make sure they list the

materials they will need for their improved subsystem

designs and label their diagrams.

4. Allow students to collect the necessary materials for

building their improved designs from the materials table.

5. Give groups time to create their subsystem designs,

reminding them to follow their plans on Engineering

Design Process: Improve! {4-7}. Assist students with

construction, if necessary.

Teacher Tip

To add an additional challenge to the “Improve” step of the Engineering Design Process, set a quantifiable “force goal” for the class. For example, challenge students to use less than X Newtons of force to move the load from the “X” on the floor to the Loading Dock. Determine the numerical value for X based on groups’ testing results from Part 2 of this lesson. Be sure to do some testing on your own to be sure you are setting a reasonable goal for your students.

Teacher Tip

Any materials not utilized by students during Part 2 of this lesson can be reused here.

115 Improving a Factory Subsystem

6. Once a group has finished creating their improved

subsystem design, have them bring it over to the Testing

Station and set it up. Groups should test their improved

subsystem designs in exactly the same way as they did in

Part 2. See pp. 109-110 for detailed testing instructions.

7. Have each group complete a second copy of Scoring Sheet

{4-8} with the results of testing their improved designs as

well as a second copy of Engineering Design Process:

Create! {4-6}. Remind students to put a “2” in the

“Design #” box on each page, as these are their second

designs.

8. Once all groups have had the opportunity to test their

improved subsystem designs, gather the attention of the

class and discuss students’ findings. Ask:

♦ What part or parts of your original subsystem

design did you decide to improve? Why did you

choose those parts?

♦ Did your group’s improved design work better than

your first design? How do you know?

♦ How might you improve your subsystem even

more?

Teacher Tip

Remind students that if they are using the single or double pulley, they must wait to set it up until they get to the Testing Station as there are “over-the-door” hooks at the Testing Station that they can use (with your assistance) to set up the simple machines.

Teacher Tip

If time permits, have students go through another cycle of the Engineering Design Process and try to improve their subsystem designs even further.

English Language Learners

Instead of having each group report their results to the entire class, pair groups together and have each group explain their improved design to the other group.

Differentiation ideas are provided in the margin of the lessons.

Student handouts are shown on the relevant pages for easy reference.

Teacher Tips pass on handy insights, many suggested by teachers during field testing.

EiE teacher guides include lesson instructions and suggestions for leading thought-provoking class discussions.

Online “Educator Resources” include short videos that help with lesson prep and show experienced EiE teachers in action. A library of “Content Connections” or extension lessons help you integrate engineering with other content areas.

For Teachers

The teacher guides make preparation, instruction, activities,

and assessment as easy as possible.

Student Response to "I would enjoy being an engineer when I grow up"

Meets Curriculum Standards

EiE aligns with all 50 state science standards, the Common Core ELA

and math standards, and the Framework for K–12 Science Education.

Supported by Rigorous Research

Each EiE curriculum unit is the result of research-based design principles

and more than 3,000 hours of development, testing, and revision.

IMPLEMENTING Common Core State Standards and AssessmentsA Workbook for State and District Leaders

UPDATED MARCH 2012

EiE has a measurable impact

Children who use EiE perform significantly better than control group students on questions about engineering, technology, and science.

Students from groups historically underrepresented in engineering (women, racial and ethnic minorities, students with an IEP, students from low-income families, and English language learners) show enhanced interest, engagement, and performance after participating in EiE when compared to students participating in a science curriculum alone or in school in general.

In addition, children who use EiE are more likely than control group children to express interest in engineering as a career.

1. Students should have already met with their groups and come up with 2-4 design ideas (4-5). Begin by discussing the word budget and give real world examples of budgets. 2. Give each group a different budget ( Between $2.00 and $6.00) should work. As groupmembers are deciding which of their models to go with, they must calculate the cost of each and determine if it fits their budget. 3. Once they have found a model they feel can pollinate effectively and remain within theirbudget, they will check with a teacher. 4. They can then move on to Activity sheet 4-6.Reflections

Have students write on an exit slip what the process of having and sticking to a budget was like. Possible extensions include thinking about budgets in other areas. What are the pros and cons ofhaving a budget? Where and when do your parents need to have a budget? Share ideas whenfinished.
