**Measure for Measure**Pre-Lab Discussion**Discuss/Define Terms**• Measure – Your definition • Measure(verb) – the process of determining the size, amount, or degree of something by using an instrument or device marked by standard units (Google Dictionary)**Discuss/Define Terms**• Estimate/Estimation (Your definition) • Estimate/Estimation(verb/noun) – To form an approximate idea of a measurement; to calculate roughly**Discuss/Define Terms**• Instrument (your definition) – • Instrument of Measurement (noun)– A device/tool for measuring the present value of a quantity under observation**Discuss/Define Terms**• Accurate/Accuracy (Your definition) – • Accurate/Accuracy (adjective/noun)– measurement that follows a current rule, model or standard; precise**Set up Lab in Journal**• Hypothesis: • Mass • Procedure: • Number and leave room for 5 steps • Data: • Paper • Fold • Label Categories: • Samples 1st Estimate 2nd Estimate Mass • Samples 1st Measurement Length**Shutter Fold**• Fold in Half • Open up, fold sides to the middle line**Procedure – Part 1**• Step 1: • Without lifting or handling the objects in your bag, estimate their mass in grams. • Record your data in the upper part of your Data Table under 1st Estimate • Step 2: • Lift each object up and handle them to estimate the mass of each in grams. • Record your data in the upper part of your Data Table under 2nd Estimate**Procedure**• Step 3: • Learn How to Use a TBPB • Use a Triple Beam Platform Balance to calculate the actual mass of each object • Record your data in your Data Table under Mass**Procedure – Part 2**• Step 4 • In this step you will measure the length of each object • HOWEVER, you may NOT use a standard unit (cm, in, etc.) you MUST use unconventional units • Horse length – 13 index nails • Record your data in the lower half of your Data Table under 1st Measurement • Step 5 • Measure the length of each object with a standard unit of measurement – cm on a ruler • Record your data in the lower half of your Data Table under 2nd Measurement**Analyze data**• Pick up Data Analysis Sheet and complete with partner at your Lab Station
