Laser and Fiber Optics14. Nuclear Technologies What else can you think of? 7 V.4.0D 5/2/11

  8. The IEEE Houston Section Committee MISSION Of the Houston Section Committee To provide Pre-University teacher in-service programs (TISP) and Support to help improve student interest in Science, Technology, Engineering and Math, and to encourage careers in STEM fields. 8 V.4.0D 5/2/11

  9. What is the Problem with Math and Science? Perceptions and Miss-Conceptions • What is the Problem with Math and Science teaching in general? • Only Math and Science are tested • Teachers do not have time for engineering and technology • Teachers are not fluent in the ability to teach STEM • General lack of spatial skills • Classroom environments do not support engineering projects • How are STEM-related careers generally perceived by teachers and students? • Usually perceived as being too hard • Girls in general do not appear to be interested in STEM subjects • Other types of careers are seen as easier and better Our task today is to find a solution…………………… So – let’s get started….. 9 V.4.0D 5/2/11

  10. TryEngineering.org A Tour of TryEngineering.org Let’s explore TryEngineering.org….. http://tryengineering.org Key Links 11 V.4.0D 5/2/11

  12. Lesson Plan 1 Give Binary a Try Find Give Binary a Try….. Use search tool Full PDF Lesson plan is displayed Click Download PDF 13 V.4.0D 5/2/11

  13. Lesson Plan 1 Give Binary A Try - Overview 14 V.4.0D 5/2/11

  14. Lesson Plan 1 Give Binary A Try - Overview • How binary codes function • Binary applications • Downloading, running, and reading a binary clock 15 V.4.0D 5/2/11

  15. Lesson Plan 1 Give Binary a Try – Materials needed Materials • Internet Access • Binary Clock Download • Online Resources • Paper plates and markers • Electric Sand Timers • Net Cetera Booklet • Datasheets: • Binary Basics. • What Time Is It? • Binary Software Download. 16 V.4.0D 5/2/11

  16. Lesson Plan 1 Give Binary a Try Binary Bytes and Computer Applications • The binary numeral system (base 2 numerals) represents numeric values using two symbols, • 0 (off) • 1 (on) • Electronic circuitry, the binary system used internally • Computers in most products 17 V.4.0D 5/2/11

  17. Lesson Plan 1 Give Binary a Try Binary Bytes and Computer Applications Binary Bytes and Computer Applications • Binary Clock Example • http://www.sb-software.com/binaryclock/ • Downloading Software – How do you know it is Safety? • E-Rate Internet Safety Rule – Always ask a parent or teacher first. 18 V.4.0D 5/2/11

  18. Lesson Plan 1 Give Binary a Try Binary Bytes and Computer Applications • Computer memory cell stores binary numbers in groups of eight bits (a byte) • Fundamental level computers are just machines for flipping binary digits on and off. • Computer stores information represented in numerical form. • Computers have trillions of bytes of memory. 19 V.4.0D 5/2/11

  19. Lesson Plan 1 Give Binary a Try How Does It Work? • Compare binary with our usual numbers. • Base ten system, the decimal system, has 10 digits. • Each position is represented by one of ten possible symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9. • When we begin counting values, we start with the symbol 0, and proceed to 9. We call this the “ones” or “units” place. 20 V.4.0D 5/2/11

  20. Lesson Plan 1 Give Binary a Try How Does It Work? • Base two system, binary, has two symbols: 0 and 1. • Walking model – Alien or Being: • Aliens are numbers that do not exist in the world. • On paper plates write a 0 on one side and a 1 on the other. • Or draw an Alien on one side and a 1 on the other. • Count and Add Binary Numbers 21 V.4.0D 5/2/11

  21. Lesson Plan 1 Give Binary a Try • KID’s MATH NOTES: • Counting means adding 1 to the previous number. • Out of symbols in a numeral system, "move to the left" one place and use a "1" to represent the ”next" place. • Reset the symbol in the ”previous” place back to the first symbol, zero. Karen: I found this graphic – thought it might be useful – if not we can loose it…. 22 V.4.0D 5/2/11

  22. Lesson Plan 1 Give Binary a Try • Compare representing numbers in binary and decimal systems. • In each world you have power. • The column to the left has the highest power and the column on the right has 0 power. In all number systems 0 power = 1. How Does It Work? Are you doubling numbers when multiplying by 2? 23 V.4.0D 5/2/11

  23. Lesson Plan 1 Give Binary a Try • Representing numbers: How Does It Work? 24 V.4.0D 5/2/11

  24. Lesson Plan 1 Give Binary a Try • Representing numbers: • Electronic Sand Timer • Number Based Clocks • How does are numbers represented? • Play with number systems for 3 minutes • What did you learn? Are you Fluent? How Does It Work? 25 V.4.0D 5/2/11

  25. Lesson Plan 1 Give Binary a Try How does it work? • Learn how binary coding works by telling time. • The clock is set up in an array: Do you see the pattern? 26 V.4.0D 5/2/11

  26. Lesson Plan 1 Give Binary a Try How does it work? Which light are illuminated will determine the hour, minute, and seconds. The time below is 10 hours, 37 minutes and 49 seconds. This is brain exercise and teaches head math and seeing patterns. 27 V.4.0D 5/2/11

  27. Lesson Plan 1 Give Binary a Try Past and Future Lessons …. HTML and Hexadecimal Code Past and Future Lessons …. HTML and Hexadecimal Code • Binary had 2 symbols: 0, 1 • Decimal has 10 symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 • Hexadecimal has 16: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F • RGB Color is what it is used for: bgcolor.html • Tags: <html><body bgcolor=“FF3300”> • View the Source of any webpage and you will see HTML Code. • Writing blogs you can toggle between visual and HTML. • WHY learn this? Visual hooks kids on writing. 28 V.4.0D 5/2/11

  28. Lesson Plan 1 Give Binary a Try Past and Future Lessons …. Computational Thinking and Computer Science Past and Future Lessons …. Computational Thinking and Computer Science • Patterns in Problems • Binary had 2 symbols: 0, 1 • Decimal has 10 symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 • Hexadecimal has 16: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F Patterns in puzzles – Zoo video Patterns in movement – Dancing with Bees Patterns in graphics – Pixels and Code Art Patterns create connections for thinking Patterns in math Patterns in the world Writing about patterns 29 V.4.0D 5/2/11
