Sample Hooks

1. Native metric users vs. Native imperial users Compare knowledge of units Lbf & lbm vs. N & kg 2. Scary slide of unit conversions 1000g=1000ml H20=1L=1kg=1000cm3 16oz=1lbm=0.016077ft3 H20=0.1202 US GAL

Speech 2 Outline

Introduction The imperial unit system is inefficient and causes problems Parts manufactured to be incompatible with metric problems in conversions/scholarly work inefficiency of the units Body Examples of problems caused  (miscalculations/communications) Miscalculation of gravity Metric system units are more connected Relationships across unit systems vs no/little relation Everyone else is on the metric system More universal How we can change to the metric system Metric preferred but both still printed for x number of years Conclusion Metric system more efficient Metric system is more universal 2 systems causes problems

Evaluation of Sample Proposals

Textbook Costs (1) Strengths 1. The paper does a good job of introducing the problem. 2. The paper justifies it's solution well. Weaknesses 1. The paper doesn't really offer alternative solutions 2. The paper needs specifics, talk about a certain student spent a certain amount on a book. Meal Plans (3) Strengths 1. Has a good introduction and catches the attention. 2. Does a very good job justifying why the current system doesn't work. Weaknesses 1. Doesn't talk about alternatives 2. Doesn't address the issue of actually implementing the plan Nuclear Power (2) Strengths 1. Very well justified argument 2. Good use of examples and evidence Weaknesses 1. Doesn't talk about how we can expand nuclear power 2. Needs to work on the introduction, it seemed like it just rushed in.

Lower and Upper Flammability Limits of

I will be doing my second major writing assignment on lower and upper flammability limits of methane in air in standard Iowa weather conditions. Due to the nature of the assignment and my topic it is likely that I will have to focus on one of the limits, not both. LFLs and UFLS have been widely tested across many conditions, however slight variations in temperature, pressure, humidity, air composition, and many other factors may have effects on the LFL and UFL. Recently I conducted a laboratory experiment on LFLs among other things, and therefor already have the data. Data was collected using a flammability chamber built by Fauske & Associates. LFLs and UFLs are extremely important chemical property data because they essentially give the % volume concentration range at which a gas will burn in air under different conditions. This is very important information because it may be used to both transport and store gasses so that they are less likely to explode or cause a fire.
