Gravimetric analysis of a metal carbonate, Chemistry lab experiment.
This easy to follow (AP) chemistry lab experiment is intended to complement your teaching on Percent Composition, Percent by mass, Concentration of Solutionor as an integral part of your Stoichiometry unit. The activity utilizes concepts of the mole, molar mass, molarity and limiting and excess reagents. The lab handout includes an illustrated materials list and a simple and clear procedure. The lab activity uses chemicals easily sourced at any chemical supplies store. The detailed illustrated

Chemistry lab: Percentage of copper in brass
This easy to follow (AP) chemistry lab experiment is intended to complement your teaching on Percent Composition, Percent by mass, or as an integral part of Concentration of Solution. The activity utilizes concepts of the mole, molar mass, molarity and the Beer-Lambert law. The lab handout includes an illustrated materials list and a simple and clear procedure. The lab activity uses chemicals easily sourced at any chemical supplies store and a brass sample procured from a hardware store. The d

Nuclear Lab Simulation
Multiple experiments in one. In one tab students are able to use a Geiger counter to determine the radiation output in CPM and use that to calculation the half life of 3 different isotopes. In another tab, students can determine the percent composition of a rock layer (i.e. C-14 to N-14) and use that to determine the age of a fossil. Students begin by typing in their name so it appears on their screen at all times and then can work through these 2 experiments. In a 3rd tab all their data is reco

Sound Pollution Assessment Lab
Sound pollution, or noise pollution, is unwanted or harmful sound that disrupts the environment. The decibel (dB) scale measures sound intensity logarithmically, meaning each 10 dB increase represents a tenfold increase in sound intensity. Prolonged exposure to sounds above 85 dB can cause hearing damage, while levels above 120 dB can cause immediate harm. Smartphone apps use the device's microphone to estimate sound levels, but their accuracy can vary based on microphone quality, calibration, a

Synthesis of Salicylic Acid Lab Simulation
Students begin by typing in their name so it appears on their screen at all times. Students are walked through the steps of saponification to isolate salicylic acid. This includes requiring students to measure out and mix reagents, perform vacuum filtration, and using boiling and ice baths. A data table collects the information and provides assistance with performing the calculations to find percent yield. Although a simulation, it is designed to not give 100% yield and students will get differe

Strong Acid Base Reaction Simulation
Students begin by typing in their name so it appears on their screen at all times. This focuses strictly on the reaction of NaOH with an unknown concentration of HCl. Students complete 4 trials which includes adding the NaOH dropwise and measuring, recording, and graphing the pH change. After 4 trials students calculation the concentration of HCl using the chemical reaction and mol ratio and not the dilution equation to ensure better understanding. Students will receive feedback if they are corr
