76 – 93 of 93 Classroom Resources
Concentration, Molarity, Mole Concept | High School
In this demonstration, students will determine the molarity of several different solutions demonstrated by the teacher.
Covalent Bonding, Ionic Bonding, Conductivity | High School
In this lab, students will analyze the conductivity of several common household solutions using a light emitting conductivity diode tester to determine if the solution is a strong or weak electrolyte. Students will interpret the brightness of the lightbulb to determine the strength of the electrolyte. Students will also have an opportunity to consider the connection between conductivity and bond type during this lab.
Solubility, Covalent Bonding, Precipitate, Ionic Bonding, Molecular Structure, Solute & Solvent, Saturated/Unsaturated/Supersaturated | Middle School, High School
In this lab, students create a snow globe by taking advantage of benzoic acid’s solubility properties in hot water.
Solubility, Precipitate, Solute & Solvent, Saturated/Unsaturated/Supersaturated | Middle School, Elementary School, High School
In this lab, students will create a supersaturated solution by dissolving borax in boiling water. They will create a snowflake using pipe cleaner to suspend in the solution, which will serve as a nucleation site for crystallization as the solution cools and remains undistributed overnight. This lab gives students an opportunity to experience the exciting crystallization process and become more familiar with an engaging chemistry spectacle!
Solubility, Concentration, Acid Base Reactions, Intermolecular Forces, Titrations, Indicators, pH | High School
In this lab, students will use a reaction to investigate temperature and the solubility of carbon dioxide and will use a neutralization reaction and an indicator to verify the amount of carbon dioxide produced at each temperature.
Observations, Physical Properties, Mixtures, Solubility, Intermolecular Forces, Polarity, Identifying an Unknown, Intermolecular Forces, Chemical Properties, Intramolecular Forces, Mixtures | High School
In this lesson, students determine whether unknown substances are polar, nonpolar, or ionic by testing their solubilities.
Concentration, Solute & Solvent, Molarity, Stoichiometry, Mole Concept, Dimensional Analysis, Tyndall Effect | High School
In this inquiry activity, students investigate types of solutions, identifying the solute and solvent, and classifying each solution. They them solve stoichiometry problems involving solutions of different concentrations.
Density, Physical Properties, Mixtures, Solubility, Freezing Point, Polarity, Phase Changes, Intermolecular Forces, Colligative Properties, Intermolecular Forces, Freezing Point Depression, Mixtures | High School
In this lesson students will explore the role of a gasoline additive, fuel line antifreeze (generally methanol or 2‑propanol), in reducing the potential of water to block fuel lines in freezing weather. Students will prepare test tube models of water-contaminated fuel tanks and explore the effect of adding different types of fuel line antifreeze. This lesson can be used to bolster concepts about miscibility, density, intermolecular forces, phase changes (freezing), and colligative properties (freezing point depression).
Solute & Solvent, Intermolecular Forces, Scientific Method | High School
In this lab, students will investigate the idea that “like dissolves like” by discovering which liquids are best suited for dissolving various substances. This can serve as a great inquiry lab prior to teaching intermolecular forces.
Mixtures, Solubility, Reaction Rate, Saturated/Unsaturated/Supersaturated | High School
In this lab, students observe how particle size, solvent temperature, and agitation affect rate of solution.
Concentration, Reaction Rate, Temperature, Graphing | Middle School, High School
In this lab, students perform an iodine clock reaction to determine how concentration and temperature effect the reaction rate.
Physical Properties, Mixtures, Solubility, Melting Point, Intermolecular Forces, Freezing Point, Polarity, Molecular Structure, Solute & Solvent, Intermolecular Forces, Boiling Point, Intramolecular Forces, Graphing, Mixtures, Lewis Structures | High School
In this lesson, students investigate how intermolecular forces effect physical properties by investigating substances’ melting points as well as solubility.
Interdisciplinary, Concentration, Review, Identifying an Unknown, Culminating Project, Molarity, Balancing Equations, Stoichiometry, Classification of Reactions, Scientific Method, Experimental Design | High School
In this lab, students identify an unknown from a list of 12 possible compounds by designing a procedure and using evidence to prove their claim. They must draw from knowledge gained throughout the year to properly develop a procedure to identify the unknown.
Observations, Physical Properties, Mixtures, Intermolecular Forces, Polarity, Intermolecular Forces, Mixtures | High School, Elementary School, Middle School
In this lab, students mix polar and nonpolar substances and then add various emulsifiers to encourage the mixing of the two substances. They use ingredients in salad dressing to relate science to real life scenarios.
Chemical Change, Precipitate, Balancing Equations, Chemical Change, Chemistry Basics, Solubility Rules, Reactions & Stoichiometry | Middle School, High School
In this lab, students use solubility rules to predict which chemical reactions will produce precipitates.
Solubility, Physical Change, Solute & Solvent | High School, Middle School
In this lab, students will prepare a solution to observe a physical change.
Observations, Physical Properties, Mixtures, Interdisciplinary, History, Chemical Properties | High School, Middle School
In this lab, students will learn about the history of invisible ink and will have the opportunity to compare two types of homemade invisible ink recipes.
Physical Properties, Mixtures, Molecular Structure, Mixtures | High School, Middle School, Elementary School
In this demonstration, the teacher will create a sequence of mixtures in a single test tube. Water, oil, food coloring and soap will be used in this demonstration to introduce the concepts of heterogeneous and homogeneous solutions as well as the idea of miscibility. Students will also have the opportunity to analyze the properties, such as surface tension of each component used.
