Assignment 1: Scientifc Method, Geologic Time - ANSWER KEY This assignment is to get you thinking about some of the Frst topics we discussed in lecture including geologic time, order of magnitude estimation, and ideas involved with the Fve fundamental concepts in Environmental Geology. This assignment has both qualitative and quantitative aspects designed to help you foster both skill sets. While this is a slightly long assignment, it will serve as a great study guide for future tests! Part 1: Scientifc Method ±or this exercise, you will Fll out the provided form on page 2 of this handout. Step 1: Pick a location to observe. This could be in your dorm room, in a coffee shop, outside on campus - wherever you like. Spend ~5 minutes in this location quietly observing. This is perhaps the most important part of the activity. Step 2: Think of a question about this space that you could answer by making some simple observations . ±or example, if you are in a coffee shop, you might wonder: what percent of customers buy both a drink and food (versus only a drink)? or if you are outside on campus: what are the main types of animals living on our campus? You probably already have a guess or an idea of the answers to these questions. Think about the observations you could make (and keep track of) to Fnd the answer. Write down what you think the answer is (your hypothesis ). Step 3: Now take some time to make observations. This will take at least about 10 min. Jot down some notes of things you observe. Use all of your senses. ±eel free to count or measure things too! Perhaps a quick drawing or a data table will help you organize. Use the back of this page or additional pages if you need more space to record observations or drawings. Circle either QL if the observation is Qualitative or QN if the observation is Quantitative . You may end up having enough data to answer multiple questions - more than you imagined when you started observing. Step 4: Once you ! ve made enough observations to answer your initial question, make an inference of what the answer is. You may Fnd that your observations do not help you answer the question. Maybe they help you answer a different question. Make a note of this in the space provided under “Inference” below. In a real experiment you would modify the type of observations you make in order to better answer your initial question, but in this exercise, it is Fne to answer another question. That
