*TITLE:

# Comparing the graphs of Boyles and Charles Gas Laws

*Annotation

This lesson focuses on the gas laws of Boyles and Charles and a comparison of the graphs that laboratory data can generate.

## *Primary Learning Outcome:

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.

*Assessed QCC:

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.

*Total Duration:

2 and one half hours

Procedures:

## Step One

Estimated Time:

2 hours

Lesson Materials to be attached:

Title: Boyles and Charles Laws Lab

Annotation:

Two separate lab exercises to enable the student to gather data to be used in graphing.

Title: Flinn Scientific www.flinnscientic

Step 2:

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.

*Assessment:

The students are assessed based on lab performance and graphing

Extension:

Students who already know the lesson can be asked specifically about the equation of the line or the slope of the line.
