11-13-17 Nature of Science Unit Test Review - Cambridge

Do Now If you were absent for the test Thursday, you have 5 minutes to prepare to take the test (e.g., sharpen pencils, briefly review your notes). Everyone else, answer the questions below in your science notebook: What kind of relationship does a controlled experiment attempt to identify? What is a key word that should be found in a question that is investigated by a controlled experiment?

Test Retake Procedures If you earned less than a “B”, you are eligible to retake the test. To retake the test, ask Mr. Santos for a copy of your test to be made. This copy will be given to you tomorrow. By Friday, 11/17, review each incorrect question from your test. On a separate piece of paper, for each question you got wrong, write down why the other choices on the test are incorrect. Ex: For Question 1, “start a new experiment” is incorrect because this is not a part of the steps of scientific inquiry. “Change their experiment” is incorrect because this would not make sense since the hypothesis was supported. This must be completed by Thursday, 11/16. If not, you will not be able to retake the test. You will need to retake the test before school (8:00am) on Friday, 11/17.

Science Fair Project Assignment #1: Purpose A science fair project begins with a good testable question. For many students, the hardest part of a science fair project is selecting a good question. Select a question that is interesting to you. The question should lead to an experiment where something is changed and the result is measured.

A good question: Must lead to an experiment not a report, demonstration or model. The question must ask about the effect of one thing on another. Is one from which you can collect measurable data or direct observations rather than opinions. Should be very narrow and specific, not broad. Is one in which the materials needed to experiment are easy to find.

Science Fair Project Assignment #1: Purpose To come up with a testable question, begin by thinking about something you’ve observed. For example, have you ever played with a parachute? Think about what variables may affect the speed at which the parachute falls. (size, shape, weight, material, length of strings, number of strings, etc.). Select one variable to test and formulate your testable question. Example: How does the type of material of the parachute’s canopy affect the rate at which it falls?

Questions How does temperature affect the bounce of a ball? Examples of good questions: Examples of poor questions: How does temperature affect the bounce of a ball? Does the shape of a container affect how fast water evaporates? Does the drop height of an object affect the size crater it will make? How do volcanoes erupt? This question is poor because it is a model not an experiment, is too vague/broad, and will not involve data collection. Why are there craters on the moon? The question is not an experiment and would require only research, not experimentation to answer. How do bean plants grow? This question is too broad and would require research rather than experimentation and collecting data.

Purpose Statement Ideas What is the effect of sunlight on the growth of plants? What is the effect of eye color on pupil dilation? How does the color of light affect the growth of plants? How does humidity affect the growth of fungi? How does the color of a material affect its absorption of heat? How does listening to different genres of music affect human heart rate? How does the type of soda affect the volume of bubbles produced when Mentos are added?

Homework: Brainstorm a Science Fair research question Come to class with 3 possible questions written down. Meet the requirements as stated in the rubric: Project Elements 5 Excellent 3 Fair Incomplete/ Incorrect   Purpose Testable question references a cause and effect relationship. There is a measurable outcome. There is only one independent variable present in the question. Testable question that does not have a measurable outcome or has multiple variables that may affect the outcome. Question not testable. Total Score /5 = %
