The hypothesis is that vegetable oil will lubricate metal the best, followed by baby oil, Softsoap, and Vaseline.

You will build a ramp, gather materials, measure out 5 ml of lubricant, label the paint brushes, color one end of the metal block, brush the lubricant onto the metal surface, time the block, record the time, and clean the ramp.

You will need a ramp, a steel block, distilled white vinegar, Vaseline, baby oil, vegetable oil, paper towels, a level surface, a stopwatch, a 5 ml calibrated container, four disposable paint brushes, and a permanent marker.

We found that Softsoap had the best average time, followed by baby oil, vegetable oil, and Vaseline. This was different from our hypothesis, which stated that vegetable oil would work the best. We learned that a substance's ability to lubricate is not determined by its density.

This science project is interesting because it shows that a substance's ability to lubricate is not determined by its density.

Experiment variations to consider include testing different angles of the ramp and testing different lengths of the ramp.

Hey there! Here are some awesome videos about this science project that we think you'll really like. They're not only super fun, but they'll also help you learn more about the science behind the project. So sit back, relax, and get ready to have some fun!!
