1. Human Dynamics Cart – Part II Lab Requirements Grade Lab Design_____/7 Investigation Question Independent/Dependent & 2 Controlled Variables Hypothesis (Prediction/Reason): What do you think the shape of the graph will look like? Explain. Video Analysis _____/5 LoggerPro Velocity vs Time graph printed Graph has axes labels with units. Graph includes a title with your student(s) name Slope of velocity vs time graph (including units) is calculated and printed on graph. Data Table _____/3 Hand-written Data Table for data collected as a class includes labels and units. Graph (Acceleration vs. Force) _____/5 Labeled axes with evenly spaced increments Axes labeled with Units Data points are clearly marked and placed correctly Appropriate Title Trend line Analysis Questions _____/10 1.Draw a labeled Force Diagram that shows all of the forces acting on the person-cart-helmet system while being pulled across the floor by a rope. 2.Consider the Acceleration vs Force graph you generated from your group’s data table. A.What is the x-intercept of your force vs. acceleration graph (include units)? B.What do you think the x-intercept tells you about the forces acting on the person/cart system? C.What is the slope of your force vs. acceleration graph (include units)? D.What do you think the slope of the graph tells you about the relationship between these two variables. Conclusion _____/5 Consider the Acceleration vs Force graph you created, write a conclusion that answers the investigative question: “what is the relationship between acceleration and force for an object being pulled with a constant mass?” Make sure your conclusion includes the following: Claim: A description of the relationship between Acceleration and Force Evidence: High and low data to support your claim Reasoning: Logical reasoning (derive new data that links the evidence to the claim) and scientific explanation (use key concepts/vocab to explain the trend in the data) Total: _____/35 Human Dynamics Cart – Part II Lab Requirements Grade Lab Design_____/7 Investigation Question Independent/Dependent & 2 Controlled Variables Hypothesis (Prediction/Reason): What do you think the shape of the graph will look like?
