ENVIRONMENTAL SCIENCE A - UNIT 1: INTRODUCTION TO ENVIRONMENTAL SCIENCE

ENVIRONMENTAL SCIENCE A - UNIT 1: INTRODUCTION TO ENVIRONMENTAL SCIENCE  lesson 1 - ANS-what is science?  what is an example of science? - ANS-studying the universe, including motions, positions, and interactions of celestial objects  what is environmental science? - ANS-the studying of the composition of the environment and organisms' interactions within the environment  which are human causes of extinction? select all that apply. - ANS-burning of fossil fuels  introduction of a foreign species  how is conservation defined? - ANS-conservation is the careful management of resources and the preservation of wildlife and habitats  how is proper science validated? - ANS-experimentation and testing  what type of science is a pseudoscience? - ANS-false  which scientific questions can be disproved by conducting tests? select all that apply. - ANS-can monkeys communicate with each other? 1 are vegetables good for growing strong bones?  do video games negatively impact mental health?  which claim is credible? - ANS-from a university article: "flying squirrels can move through the air quickly, gliding to trees."  what is the focus of environmental science? - ANS-solutions to environmental problems  which are causes of extinction? - ANS-cutting down forests, overfishing  match each contribution to science with the correct individual. - ANS-rachel carson: warned of the dangers of pesticides and herbicides  robert shelford: collected different insects specimens  frank egler: encouraged scientific research in ecology  marjory stoneman douglas: advocated for the preservation of the everglades  who helped found a national park and a group called friends of the everglades? - ANS-marjory stoneman douglas  how did robert shelford contribute to the study of environmental science? - ANS-he studied and collected insects  what is ecological succession? - ANS-ecological succession is a predictable and sequential series of changes to a community that occurs over time  lesson 2 - ANS-careers in environmental science  a community is concerned about the impact a new factory may have on the environment. which environmental science career could help with the concern? - ANS-environmental engineer  living sea corals are losing their color. which environmental science career would study this? - ANS-marine biologist  lesson 3 - ANS-the scientific method  why are hypotheses important? - ANS-they allow scientists to question observations in the world around them and explore answers, which can lead to new discoveries.  what factors may cause a scientific theory to change? select all that apply. - ANS-advances in technological and data collection methods have improved an original theory.  subsequent groups of scientists cannot replicate the results of the original scientists who formulated the theory.  which options best define calibration? select all that apply. - ANS-it is the process of evaluating and adjusting equipment used for measurement.  it is the method of ensuring the accuracy of equipment by using a known standard.  which are important steps to carry out when using scientific equipment? select all that apply. - ANS-checking that the equipment is calibrated and working correctly  deciding whether it is necessary to use protective gear such as gloves  ensuring that the correct equipment is being used to measure a given property  what defines a scientific hypothesis? - ANS-a testable and falsifiable statement made based on observations what defines a scientific theory? - ANS-an explanation of observable phenomena that is supported by evidence  which is an example of a scientific hypothesis? - ANS-a person will not get cavities if they brush their teeth daily.  a group of researchers wants to prove that their hypothesis is true and can be supported.  which of these steps would help them prove their hypothesis? - ANS-evaluate the results of their experiments to look for patterns in data.  a student performs an experiment where he collects a sample of water to test the cloudiness of the water.  which of these factors may affect the result of the test? select all that apply. - ANS-amount of total sample collected  time at which the sample was collected  depth from which the sample was collected  a student performs an activity where a rubber ball is dropped from different heights and the height to which it bounces back is recorded.  which tool might help in collecting the data for the activity? - ANS-100-foot appraiser's tape  a student collected four different samples of river water for an experiment at a specific time of day and a specific location along the river. each sample that was taken had a different volume.
