Activities
01) Significant Figures
In this lab, students complete a series of measurement activities to practice determining the correct number of significant figures.
02) Density
This lab helps students demonstrate that density is an intensive property of a substance and is independent of the shape or size of an object.
03) Graphing Mass versus Volume to Determine Density
In this lab, students will use multiple mass and volume data to graphically determine the density of a substance.
04) Percent Oxygen in Air
In this lab, students use an absolute pressure sensor to study air characteristics and determine the percent of oxygen present.
05) Conservation of Matter
In this lab, students test the law of conservation of matter for both physical and chemical changes by finding the mass of the reactants before the reaction and the mass of the products after the reaction has occurred.
06) Properties of Ionic and Covalent Compounds
In this lab, students use a conductivity sensor to determine if an unknown substance is an ionic, polar covalent, or non-polar covalent compound.
07) Electrolyte versus Non-Electrolyte Solutions
In this lab, students use a conductivity sensor to determine which substances in sports drinks (water, sugars, or salts) are electrolytes.
08) Boyle's Law
In this lab, students use an absolute pressure sensor to determine volume's effect on the pressure of a closed system containing a fixed amount of molecules at a constant temperature.
09) Gay-Lussacs's Law and Absolute Zero
In this lab, students use an absolute pressure sensor and fast response temperature sensor to determine the temperature at which all motion stops (absolute zero).
10) Phase Change
In this lab, students use a fast response temperature sensor and stainless steel temperature sensor to determine how to add heat to a substance without the temperature of the substance increasing.
11) Specific Heat
In this lab, students use a fast response temperature sensor to determine the identity of an unknown metal by calculating the specific heat of the metal and comparing it to a list of known values.
12) Heat of Fusion
In this lab, students will use a fast response temperature sensor and calorimetry to determine the heat of fusion for water.
13) Intermolecular Forces
In this lab, students will use a stainless steel temperature sensor to determine the effects of molecular size and shape on the strength of intermolecular forces for different alcohols within the same homologous series and between isomeric pairs.
14) Concentration of a Solution: Beer's Law
In this lab, students will use a colorimeter to determine the concentration of a copper(II) sulfate solution.
15) pH of Household Chemicals
In this lab, students will use a pH sensor and common household chemicals to relate pH and hydronium ion (H₃O⁺) concentration. Students will classify solutions as acidic, basic, or neutral.
16) Electrochemical Battery: Energy from Electrons
In this lab, students will use a voltage sensor to place metal reactants in their proper order on the table of standard electrode potentials.
17) Evidence of a Chemical Reaction
In this lab, students will use a fast response temperature sensor to distinguish physical changes and chemical reactions. Students will identify unknown changes as either physical or chemical reactions using evidence to support their decision.
18) Stoichiometry
In this lab, students will use a temperature sensor to determine the mole ratio between the reactants sodium hypochlorite and sodium thiosulfate.
19) Single Replacement Reactions
In this lab, students will use a colorimeter to determine the mass of copper consumed and silver deposited in a single replacement reaction.
20) Molar Mass of Copper
In this lab, students will use a voltage-current sensor to determine the molar mass of copper through electroplating in an electrolytic cell.
21) Double Replacement Reactions
In this lab, students will complete a titration to determine the amount of chloride ion in water samples.
22) Rates of Reaction
In this lab, students will use an absolute pressure sensor to determine the effects of temperature, concentration, and surface area on the rate of a chemical reaction by measuring changes in absolute pressure as the reaction proceeds.
23) Ideal Gas Law
In this lab, students will use an absolute pressure sensor and stainless steel temperature sensor to determine the number of moles of carbon dioxide gas generated during a reaction between hydrochloric acid and sodium bicarbonate.
24) Heats of Reaction and Solution
In this lab, students will use a temperature sensor to determine the molar heat of solution for sodium hydroxide and ammonium chloride when they are dissolved in water, and the molar heat of reaction when magnesium reacts with hydrochloric acid.
25) Hess's Law
In this lab, students will use a temperature sensor to show that the change in enthalpy for the reaction between solid sodium hydroxide and aqueous hydrochloric acid can be determined using both a direct and an indirect method.
26) An Acid-Base Titration
In this lab, students will use a drop counter and pH sensor to determine the concentration of a hydrochloric acid solution and an acetic acid solution by titration.
27) Diprotic Titration: Multi-Step Chemical Reactions
In this lab, students will use a drop counter and pH sensor to determine the concentration of a sodium carbonate solution. Students will learn that chemical reactions can be the sum of several individual reactions.
28) Le Chatelier's Principle
In this lab, students will use a pH sensor to determine how concentration changes effect the equilibrium of a system. Students will relate pH values with the acid-base indicator phenolphthalein.
