Termite Lab – Notebook Set-up1. Title2. Pre-lab

- Termite background/characterisitics- Scientific method overview

3. Purpose4. Personal Account

- Observations (Day 1)- Hypotheses #1, #2, #3- Choose “best” hypothesis- Experimental design/procedure for “best” hypothesis- Day 2—Carry out experiment- Observations (Day 2)- Data Table & Graphs

5. Discussion- Did data support or refute hypothesis? EXPLAIN.

6. Conclusion- What did you learn?- What is the significance?- What is your revised hypothesis (if needed)?

• Develop 1 best experimental design• Conduct experiment• Collect data• Finish writing up lab in notebook• Due Monday, 8/31

• A preliminary study testing the effectiveness of a new HIV drug was implemented on HIV-positive humanized mice at Wake Forest University. Over a period of 6 weeks, mice were split into seven equal groups. One group was given a placebo, while the other six groups were given incrementally increasing dosages of the experimental antiviral drug. Measurements of HIV viral load (viral particles per mL blood) were taken at Day 0, Day 7, Day 14, Day 21, Day 28, Day 35, and Day 42 in order to determine efficacy of the drug.

1.Title your graph & label axes w/ units2.Keep consistent scale3.Start at X & Y vertex4.Connect dots5.Key – if more than one line per axes set

Good Experimental Design
