A science barge is like a big boat that travels around and teaches people about science. It's kind of like a classroom on a boat! But it's not just any old boat, it's a special kind of boat called a barge. A barge is a flat-bottomed boat that is mostly used to carry things like cargo or supplies.
The science barge has been converted into a floating laboratory where scientists can perform experiments using renewable energy technology. This means that the boat uses energy sources like the sun, wind, and water to power the experiments on board instead of using traditional fossil fuels like oil or gas.
The science barge also has a lot of gardens on it where plants are grown in a special way called hydroponics. Hydroponics means that the plants are grown without soil and instead they get their nutrients from a special mixture of water and minerals. This is a really cool way to grow plants because it saves space and is good for the environment.
People can visit the science barge and learn about all kinds of science topics like renewable energy, plants and agriculture, and more. It's a fun and exciting way to learn about science while also enjoying the outdoors on a boat!
