Science Reasoning Center - Newton's Laws
There are three Newton's Laws passages that target students' science reasoning abilities. They are ...
This passage describes a simple experimental design exploring the effect of varying mass and varying force upon an object's acceleration. Data is presented in the form of two figures and two tables. Questions target a student's ability to understand the experimental design, to identify appropriate conclusions that are consistent with the data, to select data from the provided set, to extrapolate from the provided data to predict the result of additional trials, to recognize proportional and numerical relationships, and to identify the graphical representations of the data.
This passage describes a complex set of three experiments exploring the effect of several variables upon the amount of friction experienced by a wooden block dragged across a surface. Data is presented in the form of three different data tables. Questions target a student's ability to understand the experimental design, to recognize the effect of one variable on another, to extrapolate from the provided data in order to predict the result of conducting additional trials, and to represent the data in the form of a graph.
This passage describes a complex experiment that explores the changes in velocity over time for falling coffee filters. The effect of the number of filters upon the terminal speed is also investigated. Data is presented in the form of a diagram, two graphs and a data table. Questions target a student's ability to make meaning of written information, to select and interpret data presented in graphs and tables, and to identify conclusions that are consistent with experimental findings.
On the Resource CD:
A Resource CD is being prepared to assist classroom teachers in using this section of the website more effectively within their classrooms. The Physics Classroom plans to release the CD during the spring semester or summer of 2013.
The Newton's Laws section of the CD will include seven different passages, including these three passages. The passages are accompanied by questions, answers with thorough explanations, and a table that associates each question with a specific science reasoning skill (or college readiness standard). Each passage includes considerably more questions than those presented here in the Science Reasoning Center. In addition to PDF files, the information on the CD is also available as Microsoft Word files, allowing teachers the ability to pick and choose questions from the large bank of questions associated with each passage.
More information about the CD can be found at the Resource CD page.
