Worksheet 1 NAME:__________________________________________________________ ***This assignment must be HANDWRITTEN and will not be accepted typed*** Use the lecture notes and the textbook reading to finish this assignment. What does it mean to be subjective and objective? Which is needed in science? How is it maintained? What is a scientific observation? Why is it important that scientific observations be repeatable and objective? Give an example of a scientific observation. Describe a hypothesis. Write one hypothesis that is a testable hypothesis and one that is not. DO NOT copy one of mine:) Why can a hypothesis never be truly proven? Use the following hypothesis to help you think about this: Humans cannot live forever. What is the definition of the independent and dependent variables? Why is it important for the researcher to only manipulate one independent variable? What is a controlled experiment? Why is this so important in experimental design? What is the difference in the independent variable in the control group and the treatment group? What is a scientific theory? How is it different from how people outside of science use the term theory? What is a very simple view of the science process? A local farmer notices dramatic declines in the number of bees in his apiary. This is a major concern as bees are important pollinators for many crops. The farmer suspects it may be the new formula of pesticide that is being used on the crops. What is your independent variable: What is your dependent variable: What are your control group: What is your treatment group: What variables would the farmer have to keep constant between the control and the treatment groups?: Design a study to test whether the new pesticide is harmful to bees. If the farmer’s suspicions are accurate, then what would you expect your data to look like? (HINT: graph it and be sure to label your graph!): Let’s say that in the above experiment you did not have a control group and all the bees in the treatment group died. Would you be able to say that the pesticide was what killed the bees? Explain. Measurement What are magnitude and units? How do they relate? Give an example and label it. Biological Hierarchy Below are terms that describe the biological hierarchy. Order these terms from less complex to more complex. This will be referred to many times this term! monomer cell individual organ system atom tissue organ macromolecule Characteristics of Life List the 5 characteristics of ife: 1. 2. 3. 4. 5. The cell is the fundamental unit of life? Explain the cell. Why is reproduction via DNA a characteristic of life. In other words, without reproduction what would happen to life? Why do organisms need energy from their environment? All living organisms sense their environment and respond to it. In addition all living organisms maintain homeostasis. How are these two related? Why is homeostasis important? Why is it that all living organisms must be able to evolve as a group? What is matter? Describe and draw the three phases of matter and how they go between each phase: Solids Liquids Gasses What is the difference between mass and weight? Why is weight ok in the clinic? What are the Law of Conservation of Mass and Law of Conservation of Energy? Give examples of both. Describe elements. Describe and draw an atom. Describe protons. Describe neutrons. Describe electrons. What is an ion, cation, and an anion? What is an electrolyte? Draw an example of the Bohr Model and explain why it is useful. What are electron orbital shells? Draw and label. What is a valence shell? What is its significance to chemical bonding? Textbook Study Guide Questions Chapter 1 Answer the following questions from the textbook study guide pages for each chapter From the “Building Your Medical Vocabulary” answer the following. These will not be on the exam until they are used in lecture. 3. epi- 4. hypo- Academic Learning Using the notes and tools from lecture, and the Information under the Academic Learning Header on this week’s module, or the website linked on the QR code below, answer the following questions: Passive Learning Definition Examples of this done in the classroom or lab? A. Examples of this done at home? C. Active learning done at home (D.) is most important for exam studying. Explain why. Active learning done at home (D.) is often the thing students want to do the least. Why do you think this is? How can a positive mindset affect what you wrote in question #37? 1pt Extra Credit ***Understanding of ALL of the underlined terms in this Worksheet is needed to succeed in this class. These study tools that you create here will be a part of the AP Reference Portfolio. These extra credit points are given when the work is self-made, and turned in with a Worksheet that is not late. To further study these terms do any of the following: The best thing to do is make Study Sheets! Draw pictures with the terms (for example, when we are studying cells in week 7 you could draw a cell and label all the different parts). Make flash cards of all underlined terms (quizlet is not accepted) Make concept cards with questions that include all of the underlined terms. Make a concept map of all terms (if you don’t know what this is look it up on Wikipedia) Write out definitions of all terms (this cannot be typed) Rewrite your notes incorporating all of the lecture and additional textbook information that helped you learn the information Or come up with your own way of studying these terms. Just make sure to ok it with me to make sure you’ll get your extra credit. This must be turned in attached to this Worksheet at the time the Worksheet is due!!!! No part of the extra credit can be typed What’s working well? Are there suggestions you have to help things work better? ----------------------------------- I just need questions 1-2, 5-14, 20-24 only. I've done the rest.
