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

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

Ronald Reagan and the Iran-Contra Affair Decision-Making Simulation
The Decision at a GlanceIt is December 7, 1985. President Ronald Reagan has gathered a handful of his most senior advisers in the family quarters of the White House—away from the staff and the note-takers. The subject is a secret so closely held that most of the government does not know it exists. American hostages are being held captive in Beirut by terrorist-linked groups. A secret channel to the Islamic Republic of Iran promises their release—in exchange for American anti-tank missiles.The di
