1.4.3 Test (TST): Teacher-Scored Unit Test Test Biology Sem 1 Points Possible: 50 Name: Bryce Lau Date: In this test you will apply what you have learned in the unit. Please answer the questions below. Submit this to your teacher when you are done. 1. a) Throughout history, people have been studying the living and nonliving world. Name and describe the formal procedure scientists use to study the world around them. (5 points) b) Science has limits and cannot answer all questions. Define science, and then give an example of a question that cannot be answered by science. (5 points) 2. Scientists have a great deal of responsibility. Why is it important for scientists to accurately communicate their results to people? (5 points) 3. Complete the table below by filling in the blanks with the remaining steps of the scientific method. (5 points) 4. Experiments that lead to new discoveries are peer-reviewed by other scientists. Peer review helps determine two things. Name one of them. (5 points) 5. Matter is found throughout the universe. Is the food we eat considered new matter? Why or why not? (5 points) Application and Critical Thinking 6. Some students studied the effect of growing plants in acidic soil. Indicate which of the following is being done in each student activity: stating the question or problem, drawing a conclusion, forming a hypothesis, or conducting an experiment. (5 points) Student Activity What is Being Done? State, "Plants growing in acidic soil grow faster than the same kind of plant in regular soil." Forming a hypothesis Ask, "How does the acidity of soil affect plant growth?" Two groups of plants of the same type and size are chosen. One group is planted in regular soil. The other group is planted in soil that is acidic. Observe the growth of the plants for three months. Record the height of each plant growing in the acidic soil and each plant growing in the normal soil. State, "Since the plants in the more acidic soil did not grow as much as the plants in the normal soil, we can conclude that acidic soil is not good for growing plants of this type." 7. Describe two themes that connect all the information in biology. Use an example to help explain each theme. (5 points) 8. Technology has affected society by causing radical changes in how people live. For example, the use of pesticides has increased the amount of food available to people. Describe another example of how technology has changed how people live. (5 points) 9. Technology can have both good and bad effects. Pesticides can make crops more resistant to insects (good) but can harm humans if they are used improperly (bad). Give examples of both the good and bad effects of a technological advancement.
