Title:
Save Fred!
Purpose:
To save Fred the Worm from drowning without touching him or his life preserver.
Procedure:
First, we lifted the the boat and removed the life preserver from beneath it. Then, we pushed Fred from atop his overturned boat into his life preserver.
Pre-Lab Questions:
1. Why is it important is science to follow an agreed upon procedure?
It is important because if someone doesn't know what procedure the group decided upon, they might do something incorrect and ruin the experiment.
2. Why is it important to document your procedure and any errors or differences?
It is important because documents with data recordings can prevent future mistakes from begin made
3. Why do we not normally have food in chemistry class?
Having food around chemicals is unsafe, and should not be brought to chemistry class.
Data Table and Observations:
Fred-
Mass: 7.70g
Length: 8cm
Life Preserver-
Mass: 74mg
Diameter: 35mm
Boat-
Circumference: 26.7cm
Volume: 266mL
Calculations:
Circumference Formula: Diameter*3.14
Work: 8.5*3.14=35mm
Conclusion:
After doing this experiment, we were able to record the measurements of Fred, his life preserver, and his boat. We were also able to get him into his life preserver safely and save him.
Post Lab Questions:
1. Was one of you more a leader, and the other followed, or did you share the responsibility for ideas equally? Why did it work out that way.
Both my parter and I shared responsibility for doing the work equally, for example, we would take turns measuring, and compare results for the final product. This worked out because we have a similar way of thinking.
2. What am are you good at?
I am good at physically doing experiments, in this case, handling Fred was my strong point.
3. What do you feel you might struggle with in chemistry?
I think I will struggle with calculating math problems.
