Life Below Water, Eleventh Grade Science Projects (8 results)

The United Nations Sustainable Development Goals (UNSDGs) are a blueprint to achieve a better and more sustainable future for all.
These projects explore topics key to Life Below Water: Conserve and sustainably use the oceans, seas and marine resources.
Science Buddies' eleventh grade science projects are the perfect way for eleventh grade students to have fun exploring science, technology, engineering, and math (STEM). Our eleventh grade projects are written and tested by scientists and are specifically created for use by students in the eleventh grade. Students can choose to follow the science experiment as written or put their own spin on the project.

For a personalized list of science projects, eleventh graders can use the Science Buddies Topic Selection Wizard. The wizard asks students to respond to a series of simple statements and then uses their answers to recommend age-appropriate projects that fit their interests.

Build a Remotely Operated Vehicle (ROV) for Underwater Exploration
Science Fair Project Idea
Engineering Design Process
Have you ever wanted to explore cold or murky water? What about places where it could be dangerous or difficult for humans to swim? Remotely operated vehicles (ROVs) allow humans to take pictures, videos, and scientific samples of underwater life and habitats while safely operating the vehicle from a boat or from shore. In this project you will design and build your own small ROV that you can test in a bathtub, pool, or nearby body of water. Read more
Build an RC Boat
Science Fair Project Idea
Engineering Design Process
Do you like playing with radio-controlled (RC) toys like cars, planes, and boats? What if you could build and customize your own? In this engineering project, you will learn how to build your own RC boat using an Arduino and a plastic food storage container. Read more
Fish Markets and Sustainability
Science Fair Project Idea
Scientific Method
The sustainability of our ocean fisheries is a topic of concern for many, including environmentalists and fishermen who make their living on the bounty of the sea. It is important to use sustainable fishing practices so that our fisheries are not over-fished leading to a decline in productivity. Some states require fish markets to post information about their fish so that consumers can make informed decisions about which fish to buy. They post the type of fish (e.g., Coho Salmon), the source of… Read more
Harmful Algal Blooms in the Chesapeake Bay
Science Fair Project Idea
Scientific Method
Harmful algal blooms occur when algae, which form the base of the ocean food web, grow in massive numbers and produce toxic or harmful effects on people, fish, shellfish, marine mammals, and birds. In this project you will learn how to use archived data from continuous monitoring stations on the Chesapeake Bay to study how water quality measurements (dissolved oxygen (DO), salinity, temperature, pH, turbidity, and total chlorophyll) change before, during, and after harmful algal blooms.

Invasive Species
Science Fair Project Idea
Scientific Method
Invasive species are organisms (either plant or animal) that have been introduced into a new, non-native area and spread rapidly in the new environment due to a lack of regulation by predators. Frequently, invasive species will out-compete native species for resources which can put native species at risk. This is an especially big problem for threatened habitat and endangered species, which are already at risk. Survey your area to document cases of invasive species invading a local… Read more
Macroinvertebrates as Indicators of Pollution
Science Fair Project Idea
Scientific Method
In this science project, you will collect macroinvertebrate samples from multiple points along a body of water, ideally a small creek or stream, and test the pollution burden and biodiversity of small organisms or insects to see if pollution impacts biodiversity. Read more
Sandy Beaches and Reef Disturbance
Science Fair Project Idea
Scientific Method
When you go to the beach, you may not know if the beach is natural or man-made. The popularity of sandy beaches prompted developers in the past to bring in sand to cover rocky shorelines and turn them into more popular sandy beaches. However, the actions of the tides, currents and waves carried the extra sand out into the reef, endangering the reef and the creatures living on it. You can use a water table to conduct experiments with sand movements and reefs. How is sand moved by water? How… Read more
Silt Deposits in Streams
Science Fair Project Idea
Scientific Method
Silt is a fine sediment that collects on the bottoms of rivers, streams and lakes. The natural process of the decay of organisms into the water can lead to the production of silt at the bottom of a lake. Silt can be a rich source of nutrients for fish and bottom dwellers like crayfish. However, it can also be introduced by unnatural processes. One problem for rivers, lakes and streams is the buildup of excess fine sediment introduced by industry. Because it often contains harmful chemicals it… Read more
