Save Fred
Purpose:
The goal was to save Fred without letting him touch the water.
Procedure:
We must use paper clips to transfer Fred from the top of the boat to the life preserver. Fred must be in the life preserver to survive.
Pre-Lab Questions:
1. Why is it important in science to follow an agreed-upon procedure?
It is very important to follow an agreed-upon procedure to successfully complete the lab with little mistakes.
2. Why is it important to document your procedure and any errors or differences?
It's important to document the procedure to explain the process taken to complete the lab and see changes in the experiment.
3. Why do we not normally have food in chemistry class?
There are many chemicals in the room that have been on the floor and tables, and the chemicals could make someone ill if it gets on someone's food.
Data Tables and Observations:
______________________
|Fred | 7.8g |
|Life Preserver| 0.74g|
|Boat | 11g |
Calculations and Graphs:
1000 x 0.74 = 74 8.5 x 3.14 = 2.7
Fred: 7.8g Life Preserver: 74mg Boat: 266mL 8cm 30mm 2.7cm
Conclusion:
My partner and I successfully saved Fred
Discussion of Theory
The theory my partner and I came up with was if we stretch open the life preserver with the paper clips, we will be able to put Fred in successfully. We successfully saved Fred the first try by testing out our theory and the purpose of the experiment was fulfilled. The experiment did work because the objective was to save Fred by putting him in the life preserver which we did successfully.
Error Analysis
I accidentally forgot to put a decimal point in the weight of the life preserver and in turn made my calculations way off. I got 7400 mg as my, then I realized I didn't put a decimal point. This showed me that just a slight mistake can ruin someone's calculations.
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?
During the lab we worked equally to save Fred. However, I did more of the calculations for both of us.
2. What areas of expertise can you bring to a project? (What are you good at?)
I'm good at calculations, teamwork and collaborating with groups.
3. What do you feel you might struggle with in chemistry?
I feel I will struggle with understanding the elements in chemistry and the different types of chemicals.
