Welcome to Louisiana Sea Grant’s
Ocean Commotion Online 2020
The first Ocean Commotion was held in 1998 at LSU’s Field House. About 2,458 students and 374 teachers and chaperones spent that day exploring exhibits about some of our region’s coastal resources. Twenty-two years later, we’re hosting our first virtual Ocean Commotion due to COVID-19.
We have more than 25 exhibits this year, featuring amphibians, the ocean’s depth and pressure, hurricanes, invasive species and more! So, a special thanks to all the exhibitors and those who helped make Ocean Commotion Online a reality.
We hope you enjoy the exhibits! And don’t worry if you can’t get to all the exhibits in one day. They’ll be available for viewing for months to come.
But first, a little background info about the sea turtles in our logo this year.
|#1||Age and Growth of Fish
Ear stones in fish – the scientific name is otoliths – detect sound and vibration and help fish orient themselves in the water. For biologists, they help give the precise age of the fish.
|#2||The Adventures of Happy and Big Wanda: Backyard Bayou
Join best-selling children’s author Happy Johnson for a reading of Backyard Bayou. Learn about the importance of Louisiana wetlands, how they have been changing and what students can do to help.
|#3||Where Does the Water Go?
Learn about the power of water and how it can carry debris off your roof or trash from your yard into our streams and bayous.
|#4||What is a Watershed?
Watersheds aren’t sheds made of water, they’re areas of land where water collects and makes its way into waterways. Louisiana is part of the Mississippi River Watershed, which is the fourth largest in the world.
Have you ever sat outside at dusk and just listened to the cacophony surrounding you? Chances are, you were probably listening to at least one of the 26 different frog and toad species that call Louisiana home.
|#6||Depth and Pressure in the Ocean
Follow the journey of Styrofoam cups underwater and investigate the relationship between depth and pressure in the ocean.
Giant Salvinia, a non-native vegetation, is overtaking some parts of Louisiana. This causes big problems for navigation and the ecosystem. Learn more about this invasive species and how the state is managing it.
|#8||Oh No! Hannah’s Swamp is Changing
The book Oh No! Hannah’s Swamp is Changing introduces students to an ever-growing problem of nonindigenous, or non-native, species facing Louisiana.
|#9||How Do Fish Breathe?
The objective of this video is to understand how fish breathe under water. Viewers can recreate the experiment using items found in the average kitchen.
|#10||Geographic Impact of Hurricanes
Hurricanes impacts can be far reaching. Explore how widespread the impact of 2005’s Hurricane Katrina were by looking at how it could affected other parts of the United States.
|#11||The Ice Cube Experiment
Temperature and salinity affect the density of water. Using common household items, conduct your own experiment to see which plays a larger role and compare your results to the video.
|#12||Louisiana Art & Science Museum
Explore some of the exhibits and STEAM activities at the Louisiana Art & Science Museum.
|#13||Life as a Scientist
Learn about exciting career opportunities in the sciences and see many of the thrilling places coastal and ocean scientists visit.
|#14||The Importance of Biodiversity in our Bayous and Swamps
Learn about the awesome science of ecosystem biodiversity, terrapin turtles and the American alligator.
(WARNING: This video contains the remains of turtles and alligators.)
Conduct a backyard survey to see where mosquitoes may be breeding on your property. Report your findings as part of a citizen science program.
|#16||Phytoplankton in Lake Pontchartrain: How the Bonnet Carré Spillway opening affects populations
In this lesson, students will learn about how phytoplankton in Lake Pontchartrain fluctuate throughout the year and how the opening of the Bonnet Carré Spillway can affect those cycles.
|#17||How to Make a Pollution Catcher
Air pollution is caused by particles suspended in the atmosphere. Learn how to make a pollution catcher from everyday items typically found around the home.
|#18||River Deltaic Simulation
Assistant Professor Giulio Mariotti and graduate student Shamim Murshid, both in the Department of Oceanography and Coastal Sciences, demonstrate how a delta works.
|#19||Rubber Band Powered Boat
Power an easy-to-make boat with nothing more than a rubber band. Materials for boat building can be found (and tested) at home.
|#20||Lake Pontchartrain Salinity Stratification
In this lesson, students will learn about coastal estuarine habitats, how salinity can vary vertically in a given place and why parts of Lake Pontchartrain aren’t fully mixed.
|#21||Sea Turtles and Marine Debris
Evidence of loggerhead and green sea turtles can be found on some of Louisiana’s barrier islands. The public can help ensure the longevity of the species by preventing plastic and other waste from entering the environment and becoming marine debris that turtles often mistake for food.
Paddlefish are one of the most distinctive freshwater fishes in North America. In Louisiana, this species is primarily found throughout most of the major river systems and in large impoundments. This video provides on overview of how paddlefish spawn as part of the Native Fish in the Classroom project.
(WARNING: This video contains images of dissected fish.)
The video teaches elementary school-aged children how to be safe on a boat and the importance of wearing lifejackets.
|#24||Introduction to Wax Lake Delta
In this lesson, students will use quadrant grids (elementary school) or coordinate planes (middle school) to document dramatic changes that happened to Wax Lake Delta over the span of a month. Students will then hypothesize what has caused this change.
Learn about ocean acidification and conduct your own acidification activity.
|#26||Using Supercomputers to Study Coastal Disasters
High performance computing can model and analyze coastal disasters like hurricanes and the dead zone so scientist and local leaders can better understand risks and potential impacts.
|#27||Aerated Sewage Treatment
The water we use – for laundry, dishes or even the toilet – has to go somewhere. This video shows how aerated sewage treatment systems clean water.
