Classroom Resources: Quantitative Chemistry
26 – 42 of 42 Classroom Resources
Periodic Table, Elements, Percent Composition | Middle School
In this activity, students are introduced to the periodic table and its elements. Student will discuss that all material in the Universe is composed of elements and that the atom is the smallest particle that still has the physical and chemical properties of any given element. Students will engage in an activity to determine the percent composition of common elements in the universe, and based on their results they will hypothesize the identity of each element based on its relative abundance.
Density, Measurements | Elementary School, Middle School
In this lab, students will learn how volume and mass affect density as they make comparisons and calculations.
Concentration, Mixtures, Interdisciplinary, Scientific Method, Measurements | Middle School, High School
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
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.
Temperature, History, Accuracy, Physical Properties | Elementary School, Middle School, High School
This video tells the story of how temperature as we currently know it evolved. The first thermometers invented in the early 1600s are very different than ones we use today!
Density, Matter, Physical Properties, Measurements | Elementary School, Middle School, High School
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
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.
Dimensional Analysis | High School, Middle School
In this activity, students will interact with a web-based tutorial that uses a drag and drop interface in order to learn how to convert between units of measurement using dimensional analysis. The tutorial allows students to learn at their own pace, and also provides feedback while they are solving problems.
Concentration, Solute & Solvent, Mixtures, Solubility, Percent Composition | Middle School
In this lab, the students will investigate how the concentration of a solution affects its properties such as color and taste.
Kinetic Molecular Theory, Pressure, Gas Laws, Volume, Temperature, SI Units, Molecular Motion | High School, Middle School
In this simulation, students investigate variables of a gas. From the computer models, they can see how pressure, temperature, and volume effect gas behavior.
Scientific Notation | High School, Middle School
In this activity, students are actively involved in putting numbers into scientific notation and taking numbers out of scientific notation.
Gas Laws, Matter, Density, Density, Temperature, Pressure, Volume, Graphing, Observations, Measurements | High School, Middle School
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.
Percent Composition | High School, Middle School
In this lesson, students explore the idea of percent composition by investigating different varieties of M&M’s.
Density, Dimensional Analysis, Review, Measurements, Accuracy, Accuracy, Experimental Design, Error Analysis | High School, Middle School
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
In this lab, students will separate iron filings from iron-fortified breakfast cereals. Students will use the recorded data to conduct percent composition calculations.
Percent Composition, Scientific Method, Introduction, Percent Composition | Middle School
In this lesson, students will develop a theory of how to calculate percent composition.
Conservation of Mass, Measurements, Conservation of Mass, Chemical Change, Observations, Physical Change, Chemical Change | High School, Middle School
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.
