Now that you’ve been introduced to marine science and an example of how scientists apply the scientific method to solve a problem, you should be able to answer the following focus questions: What do marine scientists do? Is it science or not? How do scientists approach a problem in the ocean? What is the best solution to a marine science problem? How can an incorrect hypothesis still strengthen our understanding?

Kayla wants to find the width, ab, of a river. she walks along the edge of the river 65 ft and marks point c. then she walks 25 ft further and marks point d. she turns 90° and walks until her location, point a, and point c are collinear. she marks point e at this location, as shown. (a) can kayla conclude that δ and δ are similar? why or why not? (b) suppose de = 15 ft. what can kayla conclude about the width of the river?
