Essential Chemistry Starter Lab Kit
10 labs used in the Chemistry Lab Stations
Grade Level: High School
Subject: Chemistry
Activities
01) Physical or Chemical Change
Students use a pH Sensor, a Conductivity Sensor, and a Temperature Sensor to collect evidence that supports their conclusion about whether a chemical or physical change has occurred.
02) Specific Heat
Students use a temperature sensor to experimentally determine the identity of a metal based on its specific heat capacity.
03) Chemical Reactions
Students predict products of a series of chemical reactions and use a temperature, conductivity, and pH sensor to verify a chemical change.
04) Determining Limiting Reactants
Students use a Pressure Sensor to experimentally determine the limiting and excess reactant when the amount of one reactant is varied and analyze data to reveal the coefficients in the balanced reaction.
05) Types of Bonding
Students use a Conductivity Sensor to predict the type(s) of bonding between atoms in solutions made with different substances.
06) Evaporative Cooling
Students use a temperature sensor to determine the evaporation rates of different compounds and use the Molecular Model Set to help relate differences in rates to molecular composition and intermolecular forces.
07) Solution Concentration
Students use a colorimeter to construct a calibration curve of known solution concentrations and determine the unknown concentration of a solution (Beer’s law).
08) What is pH?
Students use a pH sensor to test the pH of a set of serial dilutions and make a connection between the pH value (& pOH) of a solution and its hydrogen ion (& hydroxide ion) concentration.
09) Titration of an Unknown Acid
Students use a pH sensor to conduct a strong acid and weak acid titration with a strong base.
10) Lemon Battery
Students use a voltage sensor to measure voltage produced by a lemon battery with copper and zinc electrodes, then use their data to design a lemon battery that produces enough voltage to light an LED.
