How far above or below sea level is each animal? Measure to their eye level. A mobula ray is 3 meters above the surface of the ocean. How does its distance from the surface of the ocean Compare to the vertical distance from the eyes of: The jumping dolphin? The flying seagull? The octopus? An albatross is 5 meters above the surface of the ocean. How does its distance from the surface compare to the vertical distance from the eyes of: The jumping dolphin? The flying seagull? The octopus? A clownfish is 2 meters below the surface of the ocean. How does its distance from the surface compare to the vertical distance from the eyes of: The jumping dolphin? The flying seagull? The octopus?
Form a group of 3 students. If you need to join up with 1 or 2 people, raise your hand and indicate how many group members you re looking for. Once you have your group, get a set of cards from me. Order them from Least to Greatest. Have me check them and I ll get you started on the next step!
1. Get started on Exercise Set 1 Due on Monday next week! (It would be a GREAT idea to finish before the weekend!) 2. Work on a Playlist in your Platform
