This lesson focuses on the gas laws of Boyles and Charles and a comparison of the graphs that laboratory data can generate.
Student should be able to use learned techniques in laboratory to write up an experiment and compare data from two difference experiments. The students should also learn about using a spreadsheet to write data and construct a graph using their data generated from experiment.
1: The learner should be able to utilize the following scientific process skills in lab explorations: observation, communication, metric measurement, prediction, inference, and gathering and interpretation information.
1.2: The learner will be able to judge procedures, data, and conclusions to find out the validity of scientific research.
3.1: The learner will be able to learn and use safety protocols that are specific to an exploration.
15.3: The learner will be able to utilize the gas laws to calculate and describe the impact of temperature and pressure on the volume of gas.

Lesson Materials to be attached:
Title: Boyles and Charles Laws Lab
Two separate lab exercises to enable the student to gather data to be used in graphing.
Title: Flinn Scientific www.flinnscientic
Using the data collected in the laboratory experiment, create a spreadsheet using a program such as Excel. Then graph the data using the graphing function. Compare the two graphs. Click here for a sample of students work.
The students are assessed based on lab performance and graphing
Students who already know the lesson can be asked specifically about the equation of the line or the slope of the line.
