Classroom Resources: Chemistry Basics
26 – 35 of 35 Classroom Resources
Observations, Density, Gas Laws, Density, Pressure, Temperature, Measurements, Matter, Volume, Graphing | Middle School, High 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.
Electricity, Electrostatic Forces, Subatomic Particles, Electrons, Electrons, Graphing | High School
In this lab, students will better understand that opposite charges attract each other, and like charges repel.
Physical Properties, Mixtures, Solubility, Melting Point, Freezing Point, Solute & Solvent, Intermolecular Forces, Polarity, Molecular Structure, Intermolecular Forces, Boiling Point, Lewis Structures, Mixtures, Intramolecular Forces, Graphing | High School
In this lesson, students investigate how intermolecular forces effect physical properties by investigating substances’ melting points as well as solubility.
Exothermic & Endothermic, Calorimetry, Heat, Specific Heat, Temperature, Scientific Method, Graphing, Experimental Design | High School
In this lab students construct a model of a car radiator to investigate parameters that lead to efficient cooling. Students investigate multiple variables as they experiment with various radiator designs. This lesson focuses on thermochemistry calculations and engineering practices.
Physical Properties, Concentration, Colligative Properties, Boiling Point, Accuracy, Graphing, Error Analysis, Boiling Point Elevation, Molality | High School
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 student-driven.
Physical Properties, Gas Laws, Pressure, Ideal Gas, Volume, Graphing, Error Analysis | High School
In this lab, students stack books on top of a closed syringe and use the volume change to determine the mass of the books.
Radiation, Alpha/Beta/Gamma Decay, Scientific Method, Graphing, Experimental Design | High School
In this lab, students will investigate properties of three types of ionizing radiation—alpha, beta and gamma radiation. Students will have the opportunity to design their own procedures to explore the relationship between distance and radiation intensity.
Concentration, Chemical Change, Chemical Change, Molarity, Balancing Equations, Stoichiometry, Limiting Reactant, Chemical Change, Titrations, Indicators, Measurements, Acid Base Reactions, Graphing, Error Analysis, Error Analysis, Equivalence Point | High School
In this lab, students study several concepts, including acid-base reactions, limiting reactants, and stoichiometry, by observing the contained reaction of acetic acid (diluted vinegar) with sodium hydrogen carbonate (baking soda) in an unconventional, cost effective titration.
Melting Point, Freezing Point, Phase Changes, Heat, Temperature, Heating Curve, Molecular Motion, Graphing | Middle School, High School
In this lesson, students will create a particulate model of matter that explains energy changes and transfer during a phase change.
Reaction Rate, Le Châtelier's Principle, Reversible Reactions, Establishing Equilibrium, Equilibrium Constants, Graphing | High School
In this lab, students will explore equilibrium using paper clips to mimic a chemical reaction.
