Snack Sized Science: Chalk It Up to Ocean Acidification
EarthEcho invites you to play along with us during “Snack-Sized Science”. These 15-minute interactive science demos with the EarthEcho team are meant to help your young-learners get excited to investigate the fascinating world of SCIENCE and hopefully explore more of EarthEcho’s digital resources...maybe even on their own! Snack-Sized Science: Chalk It Up to Ocean Acidification Join us as we dive into pH and ocean acidification. Get ready to play along with your own experiments as we guide you through this demonstration.
PlasticSeas Reduce Your Plastic Use Calendar 2020
This calendar has been created by the EarthEcho International Youth Leadership Council. These youth, aged 16-22, designed this calendar to increase awareness and inspire behavior change to protect our collective future. The YLC invites you to use this calendar track and change your habits and, hopefully, provide monthly ideas to help you live a more sustainable, conscientious lifestyle.
Expedition: Water by Design Virtual Field Trip with Manatee Lagoon
Explore the fascinating connection between Florida manatees and powerplants. Take a deep dive into the history of Manatee Lagoon – An FPL Eco-Discovery Center®, an educational attraction located in Riviera Beach, Fla., and the adjacent Florida Power & Light Company Riviera Beach Next Generation Clean Energy Center. Learn about the role power plants play in this threatened species’ migratory habits and survival. This 45-minute event will take place on Friday, Friday 14th at 10 a.m. EST.
What’s the Problem with Trawling?
Commercial trawling has a devastating effect on biodiversity in areas where it has been used. Large commercial trawlers have been historically decimating both marine environments and significantly decreasing stock levels to a level at which they are unable to recuperate. The impact on communities sitting on the seafloor, known as benthic communities is devastating, the primary culprit being drag trawlers with beams of up to 12 meters, and several beams often deployed at the same time. This lesson looks at the effect of commercial trawling on both fish stocks and benthic community biodiversity. Students will understand relative sizes and impacts of large-scale fishing operations, and devise a plan to reduce the impacts of trawling. Students perform percentage calculations and analyze graphs.
Go Fish - A Hands On Lesson on Fisheries
In everyday life, students can be unaware of the impact of their food choices on the environment. Therefore, it is essential that students are educated in their food choices. If students cannot link their food to where it comes from, they are unlikely to make sustainable choices in the future. “Go Fish” aims to encourage students to start thinking about fish in the ocean and how fish stocks can change for the better or for the worse. In the educational game, cards will be selected by chance, so some students ‘oceans’ may be more successful than others. Students will complete a fishing log to monitor events of the game and reflect on the events that cause a change. By playing this game, students can come aware of the negative and positive actions that can take place to encourage fish stocks or declining fish stocks.
What’s the Stake?: A Lesson on Fisheries Management
A fishery is a geographic region that contains a population of aquatic species which are a natural resource that needs to be managed. This management requires people from different backgrounds and in different fields, such as stakeholders, scientists, fisherpeople, government groups, and citizens. The goal of managing fisheries is to ensure that the different fish populations will be sustainable and a resource for now and future use. It can be a difficult thing to manage since people in different roles will have different priorities. Students will re-enact a fisheries management meeting by adopting the roles of various stakeholders in Plymouth (commercial fishers, recreational fishers, environmental groups, citizens, scientists, etc.) and advocate for a certain policy based on their role as a stakeholder.
What’s the By-Catch? Lesson Plan
Seafood serves as a primary source of food and protein for many people across the world, and the economies of many nations are heavily influenced by fish stocks and fisheries management. While efforts are in place to manage fisheries in many places around the world, there are still risks associated with fishing on a commercial scale. Many fishing vessels are equipped to target specific species of fish, for example, cod, but the large nets and trawls used for efficiency have a downside. This downside is called “bycatch”. Bycatch is defined as any non-targeted species that are brought in accidentally within the catch. In this lesson, students will use the engineering design process to create an alternative to modern fishing nets to try and reduce the amount of bycatch. They will also practice data collection and review.
Bio-Blocks - A Fish Habitat STEM Design Challenge
Global populations have for decades migrated more and more to coastal regions. This colonization of the coast has resulted in large areas of what was formerly rocky shores, salt marshes, and mudflats becoming built environment for people. What’s more, as sea levels rise more, coastal defenses are being put in place to protect towns and cities from the oceans. These coastal defenses are also replacing natural habitats that play a vital role in the life cycle of fish, including spawning locations, nurseries, and sources of planktonic food. This, in turn, is affecting the fish stocks in the oceans. During this lesson, students will gain a basic understanding of the idea that specific habitats are essential in the lifecycle of some species. Students will work through the engineering design process to build a ‘bio-block’ solution to make sea walls a more nature-friendly solution for flood protection.
Fish Hooks, Not Bird Hooks: A STEM Design Challenge
Approximately 600,000 sea birds die each year by getting caught on hooks used in line fishing. A device called the Hookpod, invented by a UK company in Devon, has a clever solution to this problem. The fish hook is covered by a case so birds cannot get hooked. At a certain depth (below the diving depth of indigenous birds) a mechanism is triggered to release the case which floats to the surface and is retrieved to be used again. These lesson ideas provide an interesting practical idea to use a particle model to explain density and pressure in a gas. Students will then take part in a STEM design challenge to make a device to respond to a pressure change at a particular depth of water.
