Mass Volume Lab n Take out a piece

Mass & Volume Lab: n Take out a piece of paper. n Write the Title and Purpose n Purpose: How does the volume of a substance relate to its mass?

Mass & Volume Lab n Data (take notes as you conduct the experiment) n n n Collect quantitative data in an appropriate table Observations/qualitative information gathered during data collection. Please write in complete sentences. Procedure: n Numbered steps in complete sentences needed to measure your independent and dependent variables. (This you can do while you gather data. )

Mass & Volume Post-Lab n Using Logger Pro and your assigned Stream computer, plot your data for your metal type (Steel or Aluminum (shiny/light). n n X axis = Volume and Y axis = Mass Write the math model and do the 5% rule. Y=m (units) x + b (units) Substitute the first letter of the y variable on the graph in for Y and the first letter of the x variable in for x. n 5% = y intercept/highest y value *100= n

Mass & Volume Post-Lab n Whiteboard a sketch of your plot. n Sketch graphs = labels/units on axes, number the axes, sketch in data points or trends, and write the graph title. n Write the math model and 5 % Share whiteboards in a circle. Please look at the following items on the next slide and then write a Conclusion summary paragraph.

Mass and Volume Post-Lab n n CER: Claim: What is density of Aluminum and Iron? Evidence: What evidence do you have to support this? Reasoning: Density is a constant physical property. How does your analysis support this?
