Classroom Resources: Quantitative Chemistry
26 – 33 of 33 Classroom Resources
-
Concentration, Mixtures, Interdisciplinary, Scientific Method, Measurements | Middle School, High School
Lab: Effect of Salt Concentration on Plants
In this lab, students will observe how salt concentration can affect the structure of a potato tuber.
-
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.
-
Density, Matter, Physical Properties, Measurements | Elementary School, Middle School, High School
Animation: Density Animation
This animation explores density on the particulate level. There are opportunities to make qualitative and quantitative comparisons between substances. **This video has no audio**
-
Conservation of Mass, History, Observations, Measurements, SI Units | Elementary School, Middle School, High School
Video: Antoine Lavoisier Video
This video tells the story of Antoine Lavoisier who many consider to be the father or modern chemistry. Lavoisier discovered oxygen and hydrogen and first proposed the Law of Conservation of Mass.
-
Gas Laws, Matter, Density, Density, Temperature, Pressure, Volume, Graphing, Observations, Measurements | High School, Middle School
Lab: Pressure Bottle
In this lab, students determine the relationship between volume and pressure of a gas and its temperature and address the common misconception that air does not have mass or density.
-
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.
-
Separating Mixtures, Percent Composition, Mixtures, Interdisciplinary, Measurements | Middle School
Lab: Metallic Breakfast
In this lab, students will separate iron filings from iron-fortified breakfast cereals. Students will use the recorded data to conduct percent composition calculations.
-
Conservation of Mass, Measurements, Conservation of Mass, Chemical Change, Observations, Physical Change, Chemical Change | High School, Middle School
Lab: Mass & Change
In this lab, students will use unified particle pictures of solid, liquid, and gas to explain the law of conservation of mass after carrying out various experiments.
