  6. A group of students is investigating what frogs eat. Each day the students observe a group of frogs in a local pond. What is it important for the students to carefully record their observations? Frogs are in danger of becoming an endangered species. Readers will help create a more frog-friendly environment. Other scientists will know exactly what the students observed. The students will be able to obtain support from the government. A 200

  7. C. Other scientists will know exactly what the students observed. A 200

  8. Which best explains why scientists need to keep accurate records of their work? It makes science appear more interesting. It helps organizations to keep track of al expenses. It allows other scientists to repeat their experiments. It is a government requirement for scientific experiments. A 300

  12. Scientists keep accurate records when they are conducting an investigation. Provide two reasons why it is important that scientists keep clear, thorough and accurate records. A 500

  13. With accurate records, a scientist can repeat the experiment or investigation to see if he or she obtains the same results. • With accurate records, other scientists can repeat the same experiment or investigation to see if they obtain similar or identical results. • With accurate records, scientists can see how their attitudes may have caused bias in the experiment. • With accurate records, other scientists can repeat the same experiment or investigation, reducing the risk of bias. • With accurate records, scientists have data to test theories and explanations. • With accurate records, scientists can study the exact relationship between different variables. • With accurate records, scientists can prove or disprove a hypothesis. A 500

  14. A group of students is conducting an experiment. At the end of their experiment, they obtain unexpected results. What should they do next? • Conduct a different kind of experiment. • Ignore all of the results that were unexpected. • Repeat the experiment to see if they reach similar results. • Create a graph of their results and communicate it to others. B 100

  15. C. Repeat the experiment to see if they reach similar results. B 100

  16. What conclusion can best be reached from a study of the work of Michael Faraday, Elisha Gray, Rachel Carson, Dorothy Hodgkin, and Xie Xide? • The greatest scientists have come from the United States. • Men have made greater contributions to science than women. • Most important scientific discoveries have already been made. • People from many different cultures have contributed to science. B 200

  17. D. People from many different cultures have contributed to science. B 200

  18. A scientist is conducting an experiment on the effects of a new virus on people. Which practice by the scientist shows the scientist is biased? • The scientist studies the virus using a high-powered microscope. • The scientist uses only research by scientists holding similar views. • The scientist creates a statistical study of people exposed to the virus. • The scientist injects humans with the virus after fully explaining all risks. B 300

  19. B. The scientist uses only research by scientists holding similar views. B 300

  20. Why might other scientists be skeptical about the above claim? • The scientist was not born in the United States. • The scientist studied chemistry at a leading U.S. university. • The scientist wanted more money from the pharmaceutical company. • The scientist may be biased since he works for the company that will produce the drug. A scientist is employed by a pharmaceutical company. The scientist discovers a unique drug that can help people fall asleep within five minutes. The scientist claims there are no negative side-effects to using the drug. B 400

  21. D. The scientist may be biased since he works for the company that will produce the drug. B 400

  22. Men and women from all countries and cultures have made important contributions to the development of science. Identify two individual who have contributed to the development of science. For each individual you identify, describe one contribution that he or she made to the world’s scientific understanding. B 500

  23. Alhazen - explained how lenses and the human eye operate. • Nicolaus Copernicus - hypothesized that planets move around the sun. • Galileo Galilei - used a telescope to study planets and performed experiments on motion. • Sir Isaac Newton - formulated the law of gravity and the laws of motion. • Sophie Germain - explained the vibration of elastic objects. • Michael Faraday - built the first electric motor • Louis Pasteur - explained how germs can cause certain diseases • George Washington Carver - developed new uses for food crops • Lise Meitner - showed it was possible to split the atomic nucleus • Barbara McClintock - explained how genes can turn on and off • Xie Xide - did research on solid-state physics and semi-conductors B 500

  24. James hypothesizes that the number of flowers on a plant will increase if the water given to the plant is increased. He wishes to design an experiment to test his hypothesis. James has four pots of geraniums to use in this experiment. • What conditions should NOT be the same for the four plants in order to test James’s hypothesis? • The size of the plants. • The temperature of the water. • The number of hours in sunlight. • The amount of water they receive. C 100

  25. D. The amount of water they receive. C 100

  26. Why is an experiment still valuable even when it does not prove that the hypothesis it is testing is true? • It does not need to be repeated. • It shows the experiment was biased. • It does not need to be communicated to others. • It eliminates the hypothesis as a possible explanation. C 200

  27. D. It eliminates the hypothesis as a possible explanation. C 200

  28. What should a student do when heating a solution in a test tube? • Cork the test tube • Wear safety goggles • Point the test tube in any direction • Hold the test tube with two fingers C 300

  29. B. Wear safety goggles C 300

  30. DAILY DOUBLE DAILY DOUBLE Place A Wager C 400

  31. A scientist is conducting an experiment on plant growth. What should the scientist do to find out how tall a plant grew each day? • Look at a leaf from the plant under the microscope. • Put the plant in a sunny place for an hour each day. • Measure the plant with a ruler at the same time each day. • Put the plant on a scale each day and weight it.

  41. A scientist places five plants of equal size in identical pots. Each plant is placed in a separate room, kept at the same temperature, and given the same amount of water at the same time each day. Each plant is exposed to a different amount of light each day. At the end of 4 weeks, the scientist measures the height of each plant. • What is the dependent variable in this experiment? • The growth of each plant • The light each plant receives • The water each plant receives • The number of flowers of each plant D 400
