How do sharks reduce drag? And what are the engineering applications? There are three types of drag present on the shark during locomotion. The first type of drag is known as frictional drag‚ which is the greatest element of drags in the shark. This is arises due to the friction created between the skin and the boundary layer and can be reduced with a condition that the boundary layer maintains a turbulent flow. The second type of drag is pressure drag‚ which causes by water deflecting off the moving

why recommended changes to the TWS unit are likely to improve outcomes (e.g.‚ evidence-based practices) (10 PT) I don’t believe that the students would benefit from repeating the lesson. Elementary schools have to stay on a strict schedule of what to teach and that was extremely challenging for me at times. If I was to make modifications on this TWS I would break down instruction into small-sub steps and practice each sub-step before moving on to ensure all students understood the material. Overview
