Lesson Plan: Clean Air Chemistry
In this lesson, students will learn about air pollution and some steps toward mitigating it. First, they will burn a candle and measure its mass and the concentration of CO2 over time. Students will discuss which data set they have more confidence in and why and then use stoichiometry to predict outcomes. Next, students explore incomplete combustion in a modelbased worksheet that shows how a lack of O2 in the burning of fuels can produce air pollution. Students work together to interpret the models, define terms, and draw conclusions. Lastly, students work in groups using Lego models to illustrate how a catalytic converter works. They race “Nature” against catalysts “Palladium,” “Platinum,” and “Rhodium” to see what breaks down air pollution molecules fastest.

Accuracy  High School
Activity: Football Accuracy
In this activity, students will analyze data collected from a football tryout. Using their knowledge of the terms accuracy and precision, students will interpret the data, and apply their understanding to several questions.

Measurements, Error Analysis, Accuracy, Accuracy, Significant Figures, Error Analysis  Middle School, High School
Lab: Accuracy, Precision, and Error in Measurements
In this lab, students make measurements of length and width using four measuring tools. They will measure the same object using measuring sticks of different precision. They will observe that the exactness of a measurement is limited by the precision of the measuring instrument.

Temperature, History, Physical Properties, Measurements, SI Units, Accuracy  Elementary School, Middle School, High School
Activity: Temperature Guys Video Questions
In this activity, students will watch a video and answer questions about how both the thermometer and the concept of temperature evolved over time

Significant Figures, Measurements, Accuracy, Density, Accuracy, Error Analysis, Error Analysis  Middle School, High School
Lab: Significant Figures and Lab Data
In this lesson, students will use laboratory equipment of different precision to collect data for several different metals, and then use the data to calculate the density of each. They will then compare their calculated densities to accepted values and determine the combination of equipment that leads to the most accurate calculation of density.

Accuracy, Measurements, Error Analysis, Accuracy, Error Analysis  High School
Lab: Glassware Accuracy
In this lab, students use different types of laboratory glassware to measure 50 mL of water and determine the accuracy of each piece of glassware.

Kinetic Molecular Theory, Ideal Gas, Gas Laws, Volume, Temperature, Graphing, Accuracy, Error Analysis  High School
Lab: Finding Absolute Zero
In this lab, students will experimentally determine the value for absolute zero in degrees Celsius.

Density, Error Analysis, Accuracy, Identifying an Unknown, Physical Properties  High School, Middle School
Lab: Density Lab
In this lab, students determine the density of several liquids and solids. They then identify an unknown metal by determining its density. They then calculate the percent error within the class for a specific sample.

Colligative Properties, Boiling Point, Molality, Concentration, Boiling Point Elevation, Graphing, Accuracy, Physical Properties, Error Analysis  High School
Lab: Changing Water's Boiling Point
In this lab, students will explore colligative properties in a quantitative approach. They will measure the effect of increasing the molality of a salt solution on the solution’s boiling point, and they will graph their data and use the slope of the line of best fit to calculate the boiling point elevation constant of water. There are three versions of the lab, some of which provide more structure and guidance and others of which are more studentdriven.

Density, Dimensional Analysis, Review, Measurements, Accuracy, Accuracy, Experimental Design, Error Analysis  High School, Middle School
Lab: Bowling Ball—Will it Sink or Float in Water?
In this lab, students will find the density of a bowling ball to determine whether it will sink or float in water.

Dimensional Analysis, Significant Figures, Measurements, Error Analysis, Accuracy, Interdisciplinary  High School
Lab: Nanoscale and SelfAssembly
In this lab, students determine both the diameter of one single BB and the length of an oleic acid molecule.

Measurements, Introduction, Dimensional Analysis, Scientific Notation, Error Analysis, Significant Figures, Accuracy, Density, Error Analysis, Interdisciplinary, Accuracy  High School
Lab: Math and Measurement
In this lab, students will practice introductory math skills that will be used in chemistry all year. This includes metric conversion, significant figures, scientific notation, dimensional analysis, density, percent error, accuracy and precision, as well as using lab equipment.
