Lab Equipment: Collecting Data

Test tubes and Bunsen burners With the person next to you in lab, decide who is going to be the test tube and who is going to be the Bunsen burner

Objectives SPI 3210 Inq.3 Determine the appropriate tools to gather precise and accurate data SPI 3210 Inq.4 Evaluate the accuracy and precision of data SPI 3210.T/E.1 Distinguish among tools and procedures best suited to conduct a specified scientific inquiry Enrichment Objective: Use significant digits when recording data in the lab

Collect Data Data = recorded observations Two Types of Data Quantitative Data- data that involves numbers or measurement Example: The length of the plant is 18.5 cm Qualitative Data- descriptive data that does NOT involve numbers or measurement Example: The Listerine has dark blue color; while, Wal-Mart and Scope are lighter blue.

Test tubes and Bunsen burners Partner time Test tubes explain what quantitative data is. Give an example that is not in the notes Bunsen burners explain what qualitative data is. Give an example that is not in the notes

Reliability of Data Accuracy refers to the closeness of a measurement to the correct or accepted value. Precision refers to the closeness of a set of measurements to each other (consistency).

Three students were asked to determine the volume of a liquid by a method of their choosing. Each student performed three trials. The table below shows the results. The actual volume of the liquid is 24.8 mL. Trial #1 Trial #2 Trial #3 Student A 24.8 mL 24.6 mL Student B 18.5 mL 18.6 mL Student C 22.3 mL 23.1 mL 19.7 mL

Objectives: What do these have to do with the notes we took? SPI 3210 Inq.3 Determine the appropriate tools to gather precise and accurate data SPI 3210 Inq.4 Evaluate the accuracy and precision of data SPI 3210.T/E.1 Distinguish among tools and procedures best suited to conduct a specified scientific inquiry Enrichment Objective: Use significant digits when recording data in the lab

Lab In today’s lab, we will measure materials using different instruments. The goal is to find the most useful and precise instrument for the type of data we are trying to collect.

Test tubes and Bunsen burners Wrapping up lab Test tubes: explain the difference in precision between a graduated cylinder and a beaker Bunsen burners: Explain the difference between accuracy and precision

Objectives: Did we do these?? SPI 3210 Inq.3 Determine the appropriate tools to gather precise and accurate data SPI 3210 Inq.4 Evaluate the accuracy and precision of data SPI 3210.T/E.1 Distinguish among tools and procedures best suited to conduct a specified scientific inquiry Enrichment Objective: Use significant digits when recording data in the lab
