PLEASE HELP DUE IN 3 HOURS Criteria and Limitations: In this section, please list at least three criteria that must be met by your train design. Also include any limitations that could prevent it from getting its cargo to the station. Criteria Limitations Design Ideas—Pros and Cons: In this section, describe three design ideas you have for your train. List at least one pro (a positive) and one con (a negative) for each design option. Description of Train Design Pro Con Train One Train Two Train Three Data: Record the results of each of the test runs you make to the train station. Be sure to describe any changes you make to your train between each test run. Train One Train Two Train Three Test Results? Any redesign? Test Results? Any redesign? Test Results? Track One Track Two Track Three Analyze Data and Refine Design: This section will include an analysis of your test results and plans for redesigning your train. Please write in complete sentences. Were any of your train designs able to get their cargo to the train station without crashing? If yes, describe the design of the successful train. If no, describe the design of the train that got closest to the station. Which of your criteria presented the most challenge to getting the train to its goal, and why? Which limitation was the biggest roadblock to getting the train to the station? Why was it important to have endothermic and exothermic processes in the building materials of your train? Which engines released thermal energy in an exothermic reaction? Which engines absorbed thermal energy in an endothermic reaction? If you could add any building item options to your virtual train to improve its design, what would those items be, and why would you need to add them?

Read the passage. excerpt from "why equal pay is worth fighting for" by senator elizabeth warren, april 17, 2014 i honestly can't believe that we're still arguing over equal pay in 2014. when i started teaching elementary school after college, the public school district didn't hide the fact that it had two pay scales: one for men and one for women. women have made incredible strides since then. but 40 years later, we're still debating equal pay for equal work. women today still earn only 77 cents for every dollar a man earns, and they're taking a hit in nearly every occupation. bloomberg analyzed census data and found that median earnings for women were lower than those for men in 264 of 265 major occupation categories. in 99.6 percent of occupations, men get paid more than women. that's not an accident; that's discrimination. the effects of this discrimination are real, and they are long lasting. today, more young women go to college than men, but unequal pay makes it harder for them to pay back student loans. pay inequality also means a tougher retirement for women. . for middle-class families today, it usually takes two incomes to get by, and many families depend as much on mom's salary as they do on dad's, if not more. women are the main breadwinners, or joint breadwinners, in two-thirds of the families across the country, and pay discrimination makes it that much harder for these families to stay afloat. women are ready to fight back against pay discrimination, but it's not easy. today, a woman can get fired for asking the guy across the hall how much money he makes. here in the senate, sen. barbara mikulski (d-md.) introduced the paycheck fairness act to give women the tools to combat wage discrimination. it would ensure that salary differences have something to do with the actual job that they are doing, and not just because they are women. senator warren states that the effects of pay discrimination are long-lasting. is this a valid argument supported by accurate evidence? no; warren weakens her point by claiming that the paycheck fairness act would "give women the tools to combat wage discrimination." yes; warren supports her point by noting, "for middle-class families today, it usually takes two incomes to get by." yes; warren supports her point by noting, "pay inequality also means a tougher retirement for women." no; warren weakens her point by noting, "today, a woman can get fired for asking the guy across the hall how much money he makes."
