Part B - Use the scientific method
Read the case study and use your knowledge of the scientific method to identify the observation, hypothesis, experiment, and conclusion.
Our English springer spaniels like our neighbors’ children and could play with them all day. We thought our dogs will never dislike any children they will ever meet. Last month when we took our dogs on a trip, we met some German tourists in a park. The dogs loved playing with the foreign family’s children. Our English springer spaniels like all children.

In the course of a conversation, you observe that three of your friends like horror movies. Horror movies happen to be your favorite type of movie as well. You also know
that all of these friends were born in the same week that you were, even in the same year.
An astrology-loving friend hypothesizes that people born in that week like horror movies more than other genres of movies. You decide to use the scientific method to test
this hypothesis.
Part A
What should you do next?
O Come up with a theory to explain why movie preference is related to birth week.
O Perform experiments to test your hypothesis.
O Propose several alternative hypotheses.
O Refine your hypothesis.

If not, how many are? Why is it important that scientists use all of their results and not just some of them? What should we do if the evidence neither supports nor contradicts the hypothesis?arrow_forwardWhich of the following statements is TRUE? A scientific law is fact. Once a theory is constructed, it is considered fact. A hypothesis is speculation that is difficult to test. An observation explains why nature does something. A scientific law summarizes a series of related observations.arrow_forward

Please use data given.arrow_forwardWhat is wrong with this statement? "The results of the experiment do not agree with the theory. Something must be wrong with the experiment."arrow_forwardWhat is wrong wrong with the following statement? "The results of the experiment do not agree with the theory. Something must be wrong with the experiment."arrow_forward
- If the results of an experiment to test your hypothesis show your hypothesis to be wrong: O the experiment was a failure. O you can make a new hypothesis and test it! O you need to redo your experiment until you prove your hypothesis correct! O you didn't follow the scientific method. O You can just fake your resultsarrow_forwardIn Section 1.3 the statement is made that it is worthwhile for scientists, auto mechanics, doctors, politicians, and poets to take a scientific approach to their professions. Discuss how each of these people could use a scientific approach in his or her profession.arrow_forwardSuppose you are trying to get lemon juice and you have no juicer. Some people say that you can get more juice from a lemon if you roll it on a hard surface, applying pressure with the palm of your hand before you cut it and squeeze out the juice. Others claim that you will get more juice if you first heat the lemon in a microwave and then cut and squeeze it. Apply the methods of science to arrive at a technique that will give the most juice from a lemon. Carry out experiments and draw conclusions based on them. Try to generate a hypothesis to explain your results.arrow_forward
- Compare the uses of the words theory and hypothesis by scientists and by the general public.arrow_forwardWhich of the following represent physical properties or changes, and which represent chemical properties or changes? You curl your hair with a curling iron. You curl your hair by getting a “permanent wave” at the hair salon. Ice on your sidewalk melts when you put salt on it. A glass of water evaporates overnight when it is left on the bedside table. Your steak chars if the skillet is too hot. Alcohol feels cool when it is spilled on the skin. Alcohol ignites when a flame is brought near it. Baking powder causes biscuits to rise.arrow_forwardWhich of the following statements are correct concerning the scientific method? There is more than one correct answer. "When a can of soda pop is opened, a fizzing sound is heard." This is an example of observation. DA scientific theory eventually becomes a law "Helium balloons float because helium is less dense than air." This statement can be considered an observation. Scientific law is a tentative interpretation or explanation. Both scientific law and theory have the potential to be proven wrong.arrow_forward
