Setting the Strategy: Engineering in the Community 10 mins.

1. Kick off a group discussion by asking: What do you think

people with STEM careers can do to achieve goals in communities? (Answers may include: STEM careers provide valuable services like health care; or that technology and engineering can make communities safer and improve how they function.)

2. K ids may be familiar with science, technology, and math

as part of their daily lives, but less so with engineering. Discuss kids' prior knowledge about this topic by asking:

? W hat is engineering? (Engineering combines science

and math to improve the world around us.)

? W hat do engineers do? (There are dozens of types

of engineering careers. Some engineers create and construct buildings, bridges, and other structures. Other engineers design planes and cars. Still others clean up oil spills, create new computer technology, or formulate new chemical compounds.)

Shifting Gears: STEM Challenge! 15 mins.

Take the idea of engineering in the community further. Have kids pair up to name the engineering aspects in their own neighborhoods. Hand out Activity Sheet A: Engineering in Our Community and ask kids to work together to imagine engineering solutions for their communities. Explain that solutions may need to be revised as new challenges appear. Have kids come up with different solutions to solve the same problem.

Use the Tablets! 15 mins.

Wrap-up Session and Reflection Activity: Ask kids to imagine themselves improving their neighborhoods with an engineering project. Kids will need to reflect on what would have to change in their neighborhoods, what they would build, and what the benefit of their engineering project would be. Then have them use the Cartoon Maker app to create a short animation that answers the question, "What engineering project can improve my community and how?"

Engineering in Our Community

If you want to see engineering in action, all you need to do is look around! When you walk through your neighborhood, what types of engineering projects might you spot? Maybe new bike lanes are being built. Buildings might have ramps for people with disabilities. There could be street signs with flashing lights to warn drivers to slow down in school zones. Engineering can be found everywhere!

Instructions: As a team, list the types of engineering you've seen in your neighborhood in the middle column of the chart below. Then think of engineering projects that could improve people's lives in your community, and write those in the last column. Imagine what your ideas could do!

Types of Engineering

Our community has...

Our community could use...

Public Buildings (like museums, town halls,

post offices, libraries)

Structures (like bridges, water towers, dams)

Technology (like lighting and traffic control)

Utilities (like sewage systems, storm

drains, electrical lines)

Public Facilities (like parks, piers, recreational areas)

Transportation (like roads, bike paths, sidewalks, buses, trains)

(from Activity 1)

SESSION 1

Explore STEM Careers 15 mins.

Have kids use their tablets to open the STEM Career Flip Book. Point them to the land surveyor in the math section. After kids read the text, ask: What skills do you need to work as a surveyor? What do surveyors do? (Answers may include: map the environment to determine property borders, help architects

plan new construction, map crime scenes, survey land under the ocean to look for oil or find dangers to boats.)

Goal Selection:

? What goals would surveyors set?

Setting the Strategy: Engineering in the Community 15 mins.

1. Discuss the responses kids wrote on Activity Sheet

A: Engineering in My Community from the previous activity. Call on volunteers and use a whiteboard or chalkboard to list some of their ideas for engineering projects that could help achieve goals in their community.

2. Explain that nothing is built in a community without

the input of engineers called urban planners. They

decide on the best places to build roads and parks. They design improvements to things like outdated sewage systems. Get kids thinking about the role of an urban planner by asking: What are some other parts of communities that are engineered?

3. Explain that urban planners rely on maps to do their

job. They need to know the location of buildings and streets. They even have maps that show where sewer or electrical cable lines run underground.

Use the Tablets! 15

mins.

1. Have kids use the tablets to search for images of

maps and blueprints (or design plans) of their city.

2. Then ask kids to open the Google Maps app on their

tablets and use the zip code of your school or local military base to locate their neighborhood. They can orient themselves by finding familiar locations such as their home, school, or local library.

3. Guide them through the app's features, such as Satellite

View to see an aerial image of their neighborhood. For even more detail, they can also access the Google Earth app with Street View (drag and drop the yellow Pegman icon) for a pedestrian's-eye view.

Wrap-up and Reflection Activity:

4. At the end of Session 1, have kids team up into

groups of two. Explain that kids will remain on these teams for the remainder of the Building Blocks program, so they should pair with someone they work well with. You may need to create the pairs, so no one feels left out. Ask the kids to choose a team name and let them know that in the next session they will be working with their teams to create a neighborhood map.

5. Ask kids to discuss within their teams what they

discovered in their neighborhood map.

SESSION 2

Shifting Gears: STEM Challenge! 45 mins.

To Get Started: Remind kids that they discussed maps and blueprints in the last session. They also used Google Maps on their tablets to locate their own neighborhood. Ask them to discuss what landmarks in their community helped orient them while using Google Maps.

1. Have kids separate into their teams and provide each

team with four copies of the Activity Sheet B: Map It or four sheets of graph paper. They will also need a printout of the map showing the neighborhood surrounding your school.

2. Instruct kids to divide the map printout into fourths

by measuring a vertical line and a horizontal line down the middle of the printout. Be sure to discuss how kids should measure the total length and width, then divide both in half to find the measurements that will create grid lines that separate the map into equal parts.

3. Explain that each team will draw the map grid-by-grid

on its Activity Sheet B: Map It activity sheets or on grid paper. Each grid square on the map will correspond to one activity sheet or one sheet of graph paper. At

completion, kids will have a larger map hand-drawn to scale of the Google map they've printed.

4. Before kids begin drawing, discuss the idea that all

maps need scale. Scale is a tool that mapmakers use to make sure the objects they place on the map are the correct size. Make sure that students understand that the size of items on a map relates to the size of the items in real life.

5. Explain that scale is determined by making a

comparison called a ratio. For mapmaking, ratios compare the measurements of a real place to the measurements on a map. For example, if the width of a drawn map is 6 inches and the width of a Google map is 3 inches then the ratio is 2/1, or 2:1. That means if students are drawing a map with a ratio of 2:1, the objects they draw on their map would be two times the size of the ones on the Google map.

6. Tell groups that they will work together to choose

the scale for their map grids. Have students use rulers to measure the width of each grid square on the Google map printout. Then measure the width of the map area on the activity sheet. If kids are using graph paper, they will measure the width of the sheet of graph paper. They will then compare the width of their graph paper to the width of the area on the Google map.

7. After they've determined the scale for the maps,

they should each use the same scale to calculate the size of map objects, such as streets or buildings, that will be included in their grid. For example, if their scale is 2:1, a building that is 2 inches wide on the Google map should be 4 inches, or twice as wide, on the maps they draw. Give students time to draw their map grids. When done, teams will piece together their grid squares and attach them to poster board to make a completed neighborhood map. After they finish their map, give teams time to reflect and make adjustments as necessary.

Drawn Map Width 6 inches 2

Example:

=

= or 2 : 1

Google Map Width 3 inches 1

Explain that as groups are working to agree on the scale they will use to draw their map grids, they should simplify the scale to make it usable.

Map It

You may know your community like the back of your hand, but this activity will give you an urban planner's?eye view of it.

Instructions: Use the map printout of the community where your school is located to draw the map one grid at a time. As you work, don't forget to draw everything to scale. This will ensure that each grid aligns with the other sections of the map.

When done, tape together each map grid to make a completed neighborhood map. Do the streets match up? Did you and your teammate use the same scale? Don't be afraid to make changes if needed.
