NAME: DATE: Lab Report
Sensory Transduction: Learn why
you feel pain when you get hit by a
rock
This lab report is for you to reflect on what you completed and learned in this
simulation, and to practice your written scientific communication skills. Include enough
detail to clearly describe the lab experience to someone who understands the concepts
but has not participated in the simulation. Use correct scientific terminology whenever
applicable. Sections
1. Describe the overall objective and make a hypothesis
2. Introduce relevant background knowledge on this topic
3. Summarize the steps taken in the simulation
4. Explain any obtained results 5. Discuss the conclusions and implications

1. Describe the overall objective and make a hypothesis.
What is the overall purpose of the experiments or activities? Make a hypothesis. Recall that
the hypothesis is a claim that answers a question or makes a prediction about an event
that has not yet occurred. Hint: The purpose is often stated in the welcome message of the simulation (as shown in
the example image below).
For your entry make sure to include the following: ●
The objective is to learn which painkiller will work for Lee.
●
I hypothesize that the correct painkiller will not inhibit his motor function.

2. Introduce relevant background knowledge on this topic.
What have you learned in class or researched on your own that would help prepare for this
simulation?
Hint: You can review the “THEORY” section in the simulation (as shown in the example
image below)
For your entry make sure to include the following: -
The sensory system detects pressure, temperature, pain, taste/smell, light, and change in concentration.
-
Afferent Neurons carry impulses from the cite of stimulus to the central nervous system.
-
Action potential correlates to electrical potential.

3. Summarize the steps taken in the simulation.
Explain all steps you completed, including the equipment and techniques you used.
Hint: You can use the “MISSION” tab in the LabPad as inspiration (as shown in the example
image below).
For your entry make sure to include the following: Dissected rat to get dorsal root ganglia
Prepared voltage clamp experiment
Conducted voltage clamp experiment
Analyzed current output
Tested rat reaction time with drugs
Analyzed motor function data

4. Describe any obtained results. Explain all obtained results. Were these results expected or unexpected? Hint: You can use the “MEDIA” tab in the Lab Pad to revisit relevant images from the
simulation (as shown in the example image below).
For your entry make sure to include the following: ●
Lidocaine was not affected by capsaicin.
●
This was expected

5. Discuss the conclusions and implications. How do your results relate back to the original purpose and your hypothesis? Were there
any systematic sources of error that could have affected the results? What did you learn? For your entry make sure to include the following: ●
Since capsaicin and lidocaine reduce withdrawal latency in rats, suggesting these drugs reduce pain.
●
I did not encounter any systematic sources of error. ●
I learned how neurons send signals based upon stimuli. I also learned of ways this can be inhibited by different ion receptors.

can you answer these questions on solar thermal collector experiment using the following bullet points.
Why does correct positioning and weather affect the results obtained?
Why it worked/failed.
In your opinion, is Solar Thermal a useful technology for the UK? Avoid giving a binary answer and try to think of all variations of solar thermal technology and all regions of the UK.
How would you modify the technology to become better/more efficient and more appropriate for the UK?
If you were given the chance to do the experiment again, how would you do it and why? The answers to these questions should be supported by mindful arguments. This should occupy, at least, two pages of the report.
