10-18-17 Cambridge - The Importance of Communication within the Science Community Standard SC.7.N.1.7

Do Now: Answer in your science notebook Why would it be important for scientists to communicate with each other? By discussing their work with others, scientists can consider different ways of analyzing data and looking at evidence. Scientists share their findings so that others can check their work, learn from their work, or expand on their findings.

Quiz on Monday, 10/23 What will be on the quiz? Identifying type of investigation given an experiment or research question Provide an example of how scientific knowledge can be gained through a method other than experimentation

Crime Scene: The Case of the Missing Computer Chip Lesson Objective: Students will be able to explain that scientific knowledge is the result of a great deal of debate and confirmation within the science community. Standard SC.7.N.1.7: Explain that scientific knowledge is the result of a great deal of debate and confirmation within the science community.

Activity Explanation This activity uses a simulation of a crime scene to help illustrate several principles of the nature of science. You will be divided into groups of 3-5. Each team will be given an introductory sheet, a diagram of the crime scene, and an envelope containing 14 clues.

Directions After reading the introductory sheet and looking at the diagram, draw 5 of the clues from the envelope at random. Using the information at hand, attempt to solve the crime by organizing the evidence in various ways that may lead to a tentative explanation.

Directions Uncover more evidence can by drawing 3 more clues. Begin the process again. Do not discourage minority opinions!

Directions Draw 3 more cards and proceed as before.

Directions You can now collaborate with another group.

Directions Draw the final 3 clues and continue until there is some general agreement. Again, allow for minority opinions!

Discussion Science is built on evidence that can be observed or deduced from the physical world. Evidence is often confusing, seemingly conflicting, and apparently random. Scientists hope to be able to find more than one line of evidence to help them solve a problem. They try to integrate this evidence into the larger amount of evidence they already have and make connections in new and different ways that may allow new and different ways of looking at a problem.

Discussion In the game, there are several independent types of clues that may be used to develop a solution. This illustrates how scientists use a variety of criteria to compare explanations and select the better ones. Another key point in this game is that scientists try to connect different lines of evidence to form a new hypothesis. With new evidence comes new ways of connecting the clues.

Discussion Human values deeply influence science Each clues is affected by how important each group member believes it is. Some people may have strong opinions or strong personalities and have a major effect on what the group thinks. But sometimes, their reasoning may not be clear.

Discussion Good science must also provide ways to exclude some alternatives. This was illustrated by how a combination of clues seem to remove certain characters from suspicion (some lacked motive, opportunity, etc.)

Discussion Scientific knowledge is the result of a great deal of debate and confirmation within the science community. By discussing others, we can consider different ways of analyzing data and looking at evidence. You shared your findings with other groups so that others can check your work, learn from your work, or expand on your findings.

Discussion Science is open ended. The game is open ended. There is not enough information presented to say with certainty who the thief is and each clues may create more questions than it helps to answer.

Summary of Key Points Scientists hope to be able to find more than one line of evidence to help them solve a problem. Scientists use a variety of criteria to compare explanations and select the better ones. Scientists try to connect different lines of evidence to form a new hypothesis. Human values deeply influence science Good science must also provide ways to exclude some alternatives. Science is open ended Scientific knowledge is the result of a great deal of debate and confirmation within the science community.
