What is viscosity?

This week we investigated the viscosity of liquids. We discovered that viscosity means how fast or slow a liquid flows. We ran a viscosity race with 4 liquids choosing from BBQ sauce, oil, water, shampoo and syrup. We made sure it was a fair test – the only element we changed was the type of liquid. We predicted which liquid would win the race. Next we carried about the test and observed what happened. We then recorded analysed and evaluated our results.

Water had the lowest viscosity and flowed the fastest. Shampoo and syrup had the highest viscosity and took the longest to flow.
