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
