October 22, 2010

1) Making Connections Lab Part A and Part B - due on Monday, October 25th. This includes fully complete Part A (data tables, histogram, and questions 1-12) and Part B (typed up lab report).

Lab Report must include (refer to pages 7/8 of the lab packet):
Organization of the Final Report
When you are finished, organize your data and determine what the data “tells you.” Also, review what you did and think about whether or not some procedures should have been done differently to give you more reliable results. Your final report should be word processed, in complete sentences, and have the following sections:
•Title- Use your notes from the previous section.
Question
•Hypothesis- Use your notes from the previous section.
•Methods and Materials- Describe the materials (what you used) and procedures (what you did) in your experiment. This may be done in the form of a list, a paragraph, or a combination of both. Use your notes from the previous section to guide you in this. (Refer to Guidelines 4 and 6.) Be sure to identify the dependent and independent variables.
•Data Collected- Include your completed data table(s) and, if appropriate, a graph or graphs to summarize the data for easier understanding of what you found.
•Discussion and Conclusions- These will relate back of the title and hypothesis for the investigation. Be sure to note whether your data supports or does not support your hypothesis. You also need to include an explanation of how or why this conclusion follows from the data you collected.
•Suggestions for Improvement- Discuss any possible sources of error that may make your data less reliable. Include a discussion of controlling the variables when investigations involve human subjects. State three additional variable that may have influenced the outcome of your experiment.
•Suggestions for Further Research- Nearly any experiment that is done produces new questions that could be answered with new investigations. Include two suggestions for other investigations that could be done or additional data that needs to be collected to further support your findings or to answer any new questions that came up during the experiment.

EXAMPLE OF A DISCUSSION/CONCLUSION:
If an individual did not exercise their clothespin squeezing rate would be higher than someone who exercised because their muscles would be relaxed and rested and thus would have the required energy to squeeze the clothespin more times in a minute. The data collected supported the hypothesis. The data collected from Austin shows that he squeezed the clothespin 100 times with no exercise and only 65 times after exercise. The experimental group who didn't exercise showed an increased clothespin squeezing rate as compared to the control group with no exercise. This was further supported in our data as Karla squeezed the clothespin 95 times without exercise and only 60 times with exercise. Therefore, our experimental data proves that clothespin squeezing rate is increased without exercise.

2) BIOBUS FORM and $5 due ASAP. You are receiving homework credit for getting this in. Remember this is a mandatory lab session occurring on November 4th.

3) INTREPID Consent Form and Photo Release Form due by Monday, October 25th. The trip is on Thursday, October 28th.
