Measuring Surface Tension
How do you measure surface tension? The fifth installment of a nine-part series is an experiment where young scientists use tubes of different sizes to measure surface tension. They calculate the average and standard deviation of the...
Curated OER
Ink Analysis
High school chemistry class members become "detectives for a day" and use the concept of paper chromatography to analyze a note left at the scene of a crime. Pupils test the ink on the note with a solvent, such as isopropyl alcohol, to...
