1. Welcome to:
The School of
Computer Science
Demonstration
Roadshow
Carnegie Mellon
http://www.cs.cmu.edu/

2. What is the Roadshow?
Goals:
 To show computer science as a broad and exciting field with the
potential for diverse participants
 To challenge stereotypes
 To show the breadth of the field
 To get students (and parents and teachers) excited about the field
and its possibilities
 To leave audiences wanting to find out more …hopefully through
further studies
A presentation by SCS students aimed at broadening
public understanding of computer science.

3. Roadshow Details
Teams of 3/4/5 Student Presenters (women and men):
• Undergraduates
• Graduates: representing Computer Science, Robotics,
Language Technologies, Human Computer Interaction
Software Engineering, and more……..
Audiences:
• K-12 boys and girls (mostly Middle/High School)
• Teachers, Parents, Educators
• Undergraduate men and women
• CS community e.g. conference audiences
Time Commitment and Travel:
• One 1 hour practice session (or 2 practices for beginners)
• Outreach day depends on location –from 1 hour total to 2 hours
• Transportation by CMU outreach bus

4. What’s in it for Presenters?….
 Public speaking and presenting experience
 Team work experience
 Teach and talk about subjects you enjoy
(teaching/explaining helps you learn)
 Build a broader resume
 It’s different and it’s Fun!

5. Why Do we Need the Roadshow?

6. The Roadshow in the Middle School
Classroom

7. The Roadshow at the Western PA
School for the Deaf

8. The Roadshow at the American
Association for Advancement of Science
Conference (AAAS)

9. SCS Students Present the Roadshow
• We would not use all of the following slides in one Roadshow.
The Roadshow team selects which slides they want to use …
…….and/or add new ones…
• It is important to have lots of interaction, especially with very young
audiences –we include at least one puzzle/game, one short video and
conclude with a demo of our robot dog.

11. Who We Are
YOU!

12. Computer
Science
is all about solving
problems…
…and using the computer to
solve some very difficult
problems.

13. Who is a Computer Scientist?
Ready to guess

20. What Is Computer
Science?

21. Lets solve a problem!
In computer science we build Algorithms…
a sequence of steps/instructions to solve a problem
Computer Science is
about problem solving
Note: Here we ask for 4 volunteers to act out the parts of the farmer, the wolf, the
sheep and the carrot—identified by different hats. Sometimes the children need a little
help to solve the problem.

22. Problem Solving
A farmer has to get a sheep, a
carrot and a wolf over the river
to the grassy field.
BUT he can only take one of
them with him at a time …

23. BUT if left alone,
Problem Solving
 The wolf will eat
the sheep
 The sheep will eat
the carrot

24. It’s MAGIC!! …….
…….Or is it?

25. The Magic of Computer Science!

 Carry on conjuring
 The 21 card trick
 The out of body experience
 The remote control brain experiment

30. Crimes and the Internet

31. Who Uses the Internet?
Who Uses E-mail and IM?
Who has Internet connection at home?

32. Some Examples:
 Purchasing music, movies, and t.v. shows
 Managing money (online banking)
 Ordering food
 Getting directions
 Playing games
 And SO many others…

33. Here’s the BAD news…
 Crime has followed the same trend and gone
online as well…
 Introducing CYBERCRIME

37. What about Computer Science
and Sports?

How can computer science help
quarterback Ben Roethlisberger
improve his game?

39. Motion Analysis

40. Raise your hand
if you think computer science can
help these athletes!

45. What Does Computer Science
have to do with Art?

46. Computer Animated Films...

47. Computer Animated Films …..

48. …are made by Computer Scientists

49. Computer Scientists take this...

50. And make this!

51. Can Computer Science
Help the Environment?

52. Going for a drive
 You drive to an
intersection where
you can turn left or
right.
 Which turn is faster to
make?

53. Going for a drive
 If you turn left, how
many lanes do you
have to cross?

54. Going for a drive
 How about a right
turn?

55. That’s Not Important.
Actually, yes it is!

56. Cars use a lot of gas.
 Yes, they do.
 Even when they’re stopped.
 Even when you’re checking
three lanes to see if cars are
coming.

57. So let’s use less gas.
 So, turning right is faster
 And it saves you gas

58. But I don’t want to turn Right
 It’s true that one right turn might not save you
any time at all, if you really just want to go left.
 But you know who makes a lot of right turns?

59. The Mailman Does!
 This guy makes a lot of
right turns.
 He used to make a lot of
left turns too.
 But not anymore.

60. He doesn’t have to go Left
 90% of the time, he goes right.
 United Parcel Services (UPS) uses computer
algorithms to find out how he can visit all the
streets he needs to go to, making very few left
turns.

61. Can Computer Science...
 Help solve crimes?
 Help athletes perform better?
 Create pieces of art?
 Help the environment?

62. Can Computer Science...

63. Human Computer Interaction
Does your computer ever make you feel like this?

64. Human Computer Interaction
Computer scientists working in human computer interaction work to make
computers easier to use.

65. Human Computer Interaction
So that hopefully you feel less frustrated when using your computer

66.  A computer can only do what it is told to do
 A program is a set of instructions telling a
machine what to do
 Programming involves learning how to write
instructions that do specific tasks
 COMPUTER SCIENCE IS SO MUCH
MORE!
What is Programming?

67. Let’s program Anthony the Robot
to make a jelly sandwich!
Note: For this exercise you will need bread, napkins, a
plastic knife and a jar of jelly. One SCS student is the
“robot” who can only follow very precise instructions.
The audience gives instructions.
