1. What is Bio-technology?Why is it important to understand your genetic make up?How does this information affect your life? Society? http://www.komonews.com/news/consumer/17071161.html Advancement of technology for research associated with life science. Especially Genetic Engineering (changing genes and recombinant DNA (changing DNA sequences)

2. Stolen IPOD? Cell Phone? We are going to begin EHS CSI training!

3. Eliminating crime at EHS by incorporating electrophoresis into our discipline policy. Would you like to help? • Tools you need to learn to use… Micro pipettes… • Electrophoresis… • Before we can use these tools we will need training on how they work…

4. What is the metric system?. Standard measurement system used through out the world • How big is a Liter? • How big is a mili Liter? • mL(1/1000 L) mili means one thousanth • How big is a micro liter compared to a L and a mL? • (1/1000 of a mL) (1/1,000,000 of a L) • Which of these units do you think would be the best for looking at pieces of DNA? • Why?

5. The MICRO LITER!! • DNA IS SO SMALL THAT IT NEEDS TO BE LOOKED AT IN VERY TINY PIECES • What tool should we use to measure DNA? • Micro-pipettes allow us to take samples as small as .5 µL and as large as 1000 µL (1 mL)

6. Are you a metric system master? • When I convert from L to mL will the number get smaller or larger? • Larger, I will move my decimal place 3 spaces to the right because it is a thousand times smaller. • When I convert from mL to µL will the number get smaller or larger? • Larger, I will move my decimal place 3 places to the right.

7. Metric System Master? • When I convert from µL to mL will the number get smaller or larger? • Smaller, I will move my decimal place 3 places to the left. For example 2 µL = .002 mL • When I convert from mL to L will the number get smaller or larger? • Smaller. I will move my decimal place 3 spaces to the left. • 2.0 mL = .002 L

8. Factor Label Method • A great way to set up conversions • Start the conversion with what you know and make a relationship that relates to what you want to know • For example when determining how many µL are in 20 L set up this conversion 20L 1,000,000 µL 1 L This means 20 X 1,000,000 =20,000,000 µL

9. Metric System Master??? • If I have L and want µL what should I do? • Move the decimal place 6 places to the right • Or set a conversion using factor label method

10. I will give you a measurement and you must tell me how many µL I have… Use Factor Label method • 2 µL = how many L? • 2 µL 1 L 1,000,000 µL 2µL X 1L /1,000,000µL = • .000002L • 87 mL = how many µL? 87mL 1,000 µL 1 mL 87mLx 1000 µL/ 1mL • 87,000 µL

11. Try these on your own…. • 100 µL = How many L • 2,300,000 L = How many mL • 45 L = How many µL? • .0001 • 2,300,000,000mL • 45,000,000 µL

12. EQUIPMENT!!! • You must show competentence before you can join the EHS crime fighting team!! • P-10 range of .5-10 µL • P-20 range of 2- 20 µL • P-200 range of 20-200 µL • P 1000 range of 200-1000 µL

13. IF YOU USE THE WRONG PIPETTE IT WILL MAKE THEM LESS ACCURATE AND MAY DESTROY THEM..AND THEY MIGHT EXPLODE! • If I want to measure 2 µL which pipette would I choose? • P-10 • If I want to measure 178 µL which pipette would I choose? • P-200 • If I want to measure 778 µL which pipette would I choose?

14. Try these on your own. • Tell me the pipet for the specific measurement. • 600 µL 25 µL • 225 µL 90 µL • 1 µL 18 µL • P-1000 4. p-200 • P-1000 5. P-200 • P-10 6. P-20

15. Use Factor label method to determine How many mL are in 2,000 чL? How many чL are in 3 L?

16. How to use pipets • Lets look at our Fabulous handout your wonderful teacher gave you….

17. Tommorrow, I’ll be back to… • Make sure you are measuring the correct amounts of DNA? • In order to participate in the lab and gain your CSI Terrace crime fighting skills… • Finish Metric system/Pipet worksheet • We’ll practice using pipets tommorrow

18. We will continue our CSI EHS crime fighter training tommorrow… • Practice your conversions and pipette choice worksheet tonight!
