Objective

SWBAT recognize and compare characteristics of marine life in the various zones that lie in the ocean.

Big Idea

Students will use ocean life to begin observe, and determine the characteristics that are need for survival in the various zones found in the ocean.

Water Pressure and Review

10 minutes

To explain water pressure, I ask the class if they have ever had pressure build up in their ears and then all of sudden they hear pop that seems to effect their hearing. This happens to us when we go into deep water. This is called hydrostatic pressure. The deeper we go under water the more we are covered by gallons of water, which adds up in weight. This weight is the pressure we are talking about as we go deeper into the ocean. 

I ask the class to share their notes from yesterday with me on the zones. I do this fairly quickly since they all create notes to reference during the activity. The activity is going to require them to work in groups and I randomly assign them by having them call off numbers 1-6. 

Read and Match

25 minutes

Once the groups are formed, students are going to be given a stack of ocean animal cards. These cards are part of a Project Wet lesson and the activity is adapted from it. They are mixed up and not in any order. Students are going to read the card carefully and try to determine which zone this animal might live in. They need to read carefully, take turns, and remember to use prompting to help each other with their reading. After each read, they need to check for understanding.

I give them a hint that the only change that occur zone to zone are in pressure, sunlight, and depth. No I just let them read and place their creatures into the zones they think they fit in. When the groups have finished, we check our findings by comparing what determinations were made and why. I facilitate the discussion and let the kids confirm and correct each other. I only help when I am needed.
