Decent Essays

Prior to doing the lab investigation, the students will sketch graphs predicting what the force and spring stretch relationship will look like. Their graphs will demonstrate that the students that their data will need to support or reject their initial predictions; more importantly, the students will get an idea of what data to gather to support or to change their predictions. Once the students have finished plotting their data, they will share their findings with the class by explaining the relationship that their data indicates. To ensure that all students understand the importance of the learning targets, they will explain to one another why it is important to become skilled in data collection and in data analysis; they will also get to …show more content…

a. Prior academic learning, prerequisite skills, and understanding of the nature of science related to the central focus—Cite evidence of what students know, what they can do, and what they are still learning to do.
As indicated by the unit preassessment, the 22 students in the classroom scored the lowest, average or below average, in the analysis level of knowledge–the knowledge level from Benjamin Bloom’s Taxonomy. Furthermore, the preassessment asked the students to answer several questions and to provide evidence to support their responses; however, none were able to provide evidence to support their responses. This lesson will target deeper level thinking skills at the analysis level. I will have them practice those skills so they become proficient at identifying the data they need to gather and at developing interpretations of their data to support their claims. Moreover, it will be emphasized that they will be performing the same kind of experiment that Robert Hooke would have followed to determine the spring constant of the students’ springs, which would indicate to the students of their engagement in a real scientific …show more content…

Because of their math background and of their previous physics lab investigations, they are all able to gather and plot data while keeping track of which the independent and depended variables are. The new skills being addressed in this segment are the producing of relevant data and its analysis to determine the relationship between the force and stretch of a spring. The students have above average mathematics skills and have demonstrated high ability in solving equations; this is significant because they will be introduced to the equation that enables them to calculate for the force or displacement of a spring once they have determined the spring constant. Similarly, their mathematics background will help them determine the slope of the graph line that they will come up with as they plot their data. Lastly, the students have calculated several slopes of lines in several experiments during their first semester of physics–this is their second
