Ocean Commotion Online 2020


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.

Sea Turtles

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 OC 2020 - LDWF 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.

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 OC 2020 - BREC Conservation video 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.

#5 OC 2020 - BREC Zoo video Amphibians 101

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.

Follow the journey of Styrofoam cups underwater and investigate the relationship between depth and pressure in the ocean.

#7 OC 2020 - LDWF video Giant Salvinia

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 OC 2020 - La Sea Grant exhibit 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 OC 2020 - CEGO video 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.

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 OC 2020 - CEGO video 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 OC 2020 - LASM exhibit Louisiana Art & Science Museum

Explore some of the exhibits and STEAM activities at the Louisiana Art & Science Museum.

#13 OC 2020 - CEGO video Life as a Scientist

(WARNING: This video contains the remains of turtles and alligators.)

#15 OC 2020 - UNO exhibit Mosquito Hunting

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 OC 2020 - La Sea Grant exhibit 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 OC 2020 - CEGO video 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 OC 2020 - CCE exhibit 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 OC 2020 - SPM exhibit 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 OC 2020 - La Sea Grant exhibit 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 OC 2020 - FWS exhibit 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.

#22 OC 2020 - STM exhibit Paddlefish Spawn

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.)

#24 OC 2020 - La Sea Grant exhibit 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.

#25 OC 2020 - YWP exhibit Ocean Acidification

Learn about ocean acidification and conduct your own acidification activity.

#26 OC 2020 - CCE exhibit Using Supercomputers to Study Coastal Disasters
