The document discusses calculating the retention factor (Rf) in chromatography using the formula Rf=Distance Spot Moved/Distance Solvent Moved. It explains the students chose this topic for their science fair project because they were not allowed to do experiments with fire or explosions, and found chromatography interesting. It also notes how the experiment relates to solar power technology through variations in pigment and coloration to create more efficient solar panels.

1. Retention Factor Dayna M. Hannah E. Jordan B.

2. Retention Factor "The retention factor of a particular material is the ratio of the distance the spot moved above the origin to the distance the solvent front moved above the origin." You can calculate the retention factor by using the formula Rf= Distance Spot Moved ------------------------------ Distance Solvent Moved

3. We chose to investigate this topic in our science fair experiment because we were not allowed to do anything with fire or explosions, and we found it extremely interesting and worthy of further investigation. Why Did We Choose This Topic?
