Module 9: Intertidal Zones and Introducing SeaPerch

January 13, 2015 PowerPoint:  Honors Marine Biology Module 9 Intertidal Zones January 17, 2013

SeaPerch Underwater ROV Program

Each year the Association for Unmanned Vehicles Systems International (AUVSI) offers a series of educational programs as well as robotics competitions that allow students to apply their STEM education outside the classroom.  Our class was awarded a grant for this project.  The experience is an ideal preparation for entering the workforce,which is why participating students are frequently offered coveted internships and employment opportunities while still in school.  This year we are providing students with a hands-on robotic activity to designed to fuel and sustain their interest in science, technology, engineering and math (STEM).

Four groups have been formed in class and will build and then test their vehicles.  I am allowing class time each week to work on their project.  We have scheduled April 28, 2015 for the launch test day.  More information will be provided in the future.

Module 9 begins our study of  the Intertidal Zone . This is the area of shoreline between high and low tides.  It is also known as the Littoral Zone.  This coastal strip where the land meets the sea is by far the smallest area in all the world’s marine environments, yet more is known about it than any other. This is a narrow strip of land that is only a few meters in width, and it is defined as the area between the oceans’ high tide and low tides.  Although it is small, it is the most accessible place to scientists, and is therefore the most studied marine habitat. Even though this zone is small, it has the greatest variation of environmental factors as compared to any other marine ecosystem.  There are even several differences within a single square meter containing huge diversities of life.  As the tides rise and fall, covering and then exposing areas along the coast we can observe the dramatic changes in the environmental conditions.  Review this week’s PowerPoint after you have read your reading assignment in Module 9.

This week’s class was Mr. Wilson last day with us. For the past eight years I have been blessed to have been able to teach with Mr. Wilson and I have learned so much from him. Each week we have turned a Sunday school classroom into a science lab.  He has brought to our students his unmatched expertise of marine science and biology.  His  enthusiasm for science has excited students to love it too! It has been a joy to learn of several  students through the years who have received internships at Mote Marine and have chosen to pursue marine science and/or biology as a career.  They have all said it is because of the Marine Biology class they took with Mr. Wilson. I know you will join me in thanking him for his many years of teaching our children and blessing him in his future career.  Mr. Wilson, you will be missed.

Have a good week. -Mrs. S
