1. Science 7

2. Review From Last Class Do you have…? Senses Lab Sheet
Data table (On Graph Paper)
Analysis Questions Completed

3. Calculating Average
For each trial you are required to calculate average or mean of your trials
Mean= T1+T2+T3+T4+T5 5
If you had a “dropped” ruler you add it as 30cm
t = d X 1000 g
Where:
t = Reaction time (milliseconds)
d = Distance ruler dropped (cm)
g = Acceleration due to gravity (980 cm/sec2)
X 1000 = To convert the time from seconds to milliseconds.
Extension: Calculate reaction time in milliseconds

4. Graphing and Reporting

5. Bar Graph
Average Reaction Time of 3 Senses
cm Drop Average

6. Formal Lab Report You must include the following in your typed report:
Problem Statement (written on Wednesday)
Hypothesis (written on Wednesday- do NOT make changes even if it’s wrong)
Materials used
Data (chart of your trial results; Bar Graph- title, x & y axis labelled, correct independent and dependent variables labelled)
Analysis questions (from worksheet)
Conclusion statement (next slide)

7. Conclusion Statement- RERUN
Restate: Restate the lab experiment. Describe the assignment. (include your independent, dependent and controlled variables)
Explain: Explain the purpose of the lab. What were you trying to figure out or discover? Talk briefly about the procedure you followed to complete the lab.
Results: Explain your results. Confirm whether or not your hypothesis was supported by the results. (Use simple language such as, “The results supported the hypothesis,” or “The results did not support the hypothesis.”)
Uncertainties: Account for uncertainties and errors. Explain, for example, if there were other circumstances beyond your control that impacted the experiment (“Controlled Variables” that weren’t controlled)
New: Discuss new questions or discoveries that emerged from the experiment.

8. Computer Lab Before we go make sure you have:
Rough Draft
Graph Paper
Copy of Checklist/How to Write a Conclusion document
Please bring everything with you, you will be dismissed from computer lab

9. Finished? You have 2 options for submitting your assignment:
the assignment to ; hand in graphs if created by hand
