THE BUGGY LAB

I. PROBLEMDesign an experiment to determine the relationship between theposition of a toy buggy and time.

You have access to rulers, meter sticks, tape measures, andstopwatches.

II. DESIGN ___ Describe your experimental design with both a labeled diagram

and a verbal description. ___ State what the independent and dependent variables are. ___ Include how will you vary and measure your chosen parameters.

III. DATA ___ Perform the experiment and record your measurements in an

appropriate table.

IV. ANALYSIS ___ Graph and determine the numerical model for your data set.

V. CONCLUSION ___ What pattern did you find from your observations? Write a verbal

and mathematical description. ___ What is the physical significance of the slope of the graph? ___ What is the physical significance of the y-intercept? ___ Turn your numerical model into a general model.

You will be assessed using the rubric on the back of this page.
