1. 1441 Laboratory BIOL 1441-033 Tue 3:00 – 4:50 LS 207 BIOL 1441-030 Wed 11:00 – 12:50 LS 200 BIOL 1441-037 Fri 11:00 – 12:50 LS 200 Heath Blackmon LS 459 Office Hours: 10:30-12:00 Tue and Thu heath.blackmon@mavs.uta.edu

2. Syllabus

3. Safety Training If you do not get confirmation that you have completed the online training, then you must contact the office of compliance. Your GTA is unable to access those records or make any changes.

4. Typical lab day: You will show up on time and a quiz will be administered: up to ½ new material...so read ahead! If you are late, you do not get to take the quiz We will highlight key concepts and go over how the experiment will be performed Perform the experiment(s) and keep a record of your results

5. IntroLabs Website http://biology.uta.edu/introlabs/ Posting of the syllabus, announcements, supplemental materials, etc... Check announcements often....if there is supplemental material for the lab, print it off and bring it with you to lab.

6. Laboratory 1: Lab Safety The Scientific Method The Metric System Lab Manual pages 1-20

7. Lab Safety Material Safety Data Sheets (MSDS) Blood-Borne Pathogens – If there is an accident, do not help one another clean up blood No Horseplay Use Common Sense

8. The Scientific Method Critical method of evaluating observations in science 1.Make an observation and construct a related question. 2.Formulate a hypothesis and make a prediction. 3.Design and perform experiments 4.Conclusion

9. The Scientific Method Experiments: – Independent variable: is manipulated – Dependant variable: is measured – Controlled variable: kept constant – Experimental group: contains the manipulated organisms – Control group: contains the organisms that are held constant

10. The Metric System The system of measurement universally used by scientists. Base 10 system of measurement. Basic units: mass = grams, volume = Liters, length = meters Consult page 2 of your lab manual for specific conversions

11. Dimensional Analysis Always show your units and cancel them as you do your conversions this will eliminate careless mistakes.

12. Assignment Download Web Assignment 1 and complete it. Turn it in at the beginning of class next week. Make sure you purchase the lab manual Complete your online safety training...you can be dropped from the class if you do not.
