A. Uses an objective process Is updated constantly B. Is not objective Does not use a process Resists new information A: "Science"; B: "Pseudoscience" Kaylee wants to test her hypothesis that she performs better on tests after getting more sleep.In which way will she best be able to do this? by analyzing her average test scores after nights with different amounts of sleep Justin notices a particular type of caterpillar feeds only on cottonwood trees in his neighborhood.In which way has Justin increased his scientific knowledge? He has made observations about the natural world Which describes a scientist being creative? Sara tries turning a test tube upside down to collect a gas. This chart represents four famous scientists and an aspect of their contributions. Gutenberg The idea that people behave in odd ways on a full moon is an example of pseudoscience. Jamie is not sure a new medication will work because it has not had a large test group. Is Jamie being creative? No, he is being skeptical. Letti is having a problem in her experiment that she does not know how to solve. In order to move forward, Letti needs to be creative Curiosity is important in the progress of science because it encourages new experimentation A new drug to combat acne has been developed from a compound that is found in a melon. Which scientists would contribute to the development of the drug? biologists, chemists, and physicians Quarks are thought to be the building blocks of protons. Which was most affected by the discovery of the quark? the view that the atom cannot be broken down further than protons A scientist reads relevant literature and designs her experiment. She repeats her experiment several times and collects an entire set of data every time. As compared to a single data set, the multiple data sets lead her to modified conclusions. How is skepticism important to the progress of science in this scenario? It led to the collection of several complete data sets. The first known telescopes, used around 1600, consisted of a lens and an eyepiece. Today, telescopes are often computer controlled and consist of a complicated array of sophisticated lenses. Which statement correctly describes how telescopes have changed over time? The telescopes of the 1600s were gradually improved upon over time, resulting in the telescopes that are available today. Which will most likely lead to new scientific discoveries in future years? current scientific knowledge Which trait would most likely lead a scientist to repeat an experiment and verify the data? skepticism Microscopes are used to study the structures of rocks. Over time, microscopes have become more and more powerful. has become increasingly detailed A teacher discusses a scientific theory that has been in place for almost a century. Which would present the greatest challenge to this theory? results from new experiments that contradict the theory The EPA is trying to decide whether or not to ban a certain chemical that has been associated with acid rain. What would be the most helpful in their decision-making process? ... What are positive effects of plastics? moldability, affordability, and durability How might society have been most likely impacted if Nikola Tesla, the inventor of AC technology, had not become a scientist? People's homes might not have been built with electricity. This chart represents four government agencies and a contribution each has made to society.\ Where is the error in this table The UNEP's and USDA's contributions are switched. Which scientific information most likely lead to school districts requiring vaccines? Vaccines prevent diseases and can improve a school's safety Hannah wants to write a book about how scientists and society interact, and she has generated ideas for chapters. Which chapter would be incorrect to include in her book? how water evaporates and then forms rain and snow Which are negative impacts that the internal combustion engine has had on society? noise pollution and health problems An advertisement for a new fish food claims that lab studies show that fish grew three inches in three weeks while eating the food. Travis wondered if the food was worth the extra cost. To evaluate the claim in the advertisement, Travis should look at the data for the control group to see how much the fish grew without the new food. Lidia plans an experimental investigation to see how the thickness of a lens affects the point where a beam of light is focused. She plans to shine light through a lens and measure the distance to a screen that is placed where the beam focuses. What are the controls in Lidia's investigation? the type of light and the material of the lens Omar observes that many buildings in his city were built using limestone. He has read that acid rain can damage limestone. He also knows that limestone reacts with acids and that chemical reactions are affected by temperature. With this in mind, he conducts an investigation to see how the amount of damage to the limestone is affected by the amount of acid on the stone. Which statement describes the correct plan for his procedure? The temperature, the type of limestone, and the type of acid are controls. The amount of acid and the amount of damage to the limestone are variables Keisha is making a table summarizing her notes about the different types of investigation. She places an X into the table to show which type of investigation includes that step. Part of the table is shown. Where should Keisha place an X? in Box 1 Which question about dogs could be answered through scientific investigation How fast does an Australian terrier grow? Pablo wants to enter the science fair. Which question could be answered through scientific investigation What is the best angle to throw a ball for maximum distance? Candace is interested in learning more about colors. Which question about colors could be answered through scientific investigation? Which color bends the most to make a rainbow? Chou is curious about the effect of magnets on how plants grow. He sets up ten pots with alfalfa sprouts. He places strong magnets under five of the pots but does not put magnets under the other five pots. This is an example of which scientific practice? performing an investigation For which question could a testable hypothesis be developed? Does all wood float in water? A describes something in nature and predicts how it will behave without explaining why. law Chan Hee is inflating a basketball using an air pump. He notices that the pump gets warm as he uses it. What is a good hypothesis that could lead to new experimentation If air in a pump is squeezed more, then the air gets hotter because energy is added to it. What is a main reason why the scientific model of atoms is considered a theory rather than a law? It has been changed over time After an investigation, Kuri determines that her hypothesis was wrong. What is the best thing for Kuri to do next? write a new hypothesis and conduct new experiments to explore the matter Which statement describes a scientific theory? A theory changes based on new observations and testing. What effect, if any, does the development of new areas of science and technology have on theories? Theories may change as a result of new information. Which phrase is most likely to start a description of a scientific theory? Based on the observations made and experiments performed over the last fifty years . . ." Which set of data is best described as accurate and precise when compared to an accepted value of 125? 122, 126, 121, 123 A scientist conducted one trial of an experiment and got unexpected results. How can the scientist increase confidence in the results by repeating the experiment several times
