The St. Johns River is about 310 miles long, making it the longest river in Florida.
The picture shown on this slide depicts a new type of dock that can be used to allow penetration of sunlight to reach underneath the dock. This allows aquatic plants below the dock to receive the sunlight needed to grow.
The picture in this slide shows students demonstrating the EnviroScape, a watershed model.
Divides will separate watersheds from each other. A divide is an area of higher ground that separates two watersheds. The important thing to remember about watersheds is that whatever we put down on the ground, fertilizers, pesticides, etc. could end up in our waterways – because all land drains into a water body.
Why does a river flow north?A. That is where the river flows into the ocean.B. It is being pumped.C. It is flowing downhillD. It is flowing uphill.
The correct answer is C. It is flowing downhill.The headwaters are at a higherelevation than the mouth of theriver.
You’re correct.A river flows downhill or from a higher elevation to alower elevation.
Why are many of the rivers in theSouth a dark color?A. The water is polluted.B. The soil makes the water appear to be a dark color.C. Tannins released from decomposing plant material stain the water a dark color, like a tea bag. D. None of the above.
The correct answer is C. Tannins released fromdecomposing plant material stain the water a darkcolor, like a tea bag.It is part of the natural process for tannins to be releasedand the rivers are called a dark water system.In these systems, sunlight is limited in how deeply it canpenetrate through the water. Sunlight is important forphotosynthesis. Photosynthesis helps to place oxygen inthe water and is important for the health of a river.
You’re correct.It is part of the natural process for tannins to be releasedand the rivers’ ecosystem and inhabitants are adjusted toa dark water system.In these systems, sunlight is limited in how deeply it canpenetrate through the water. Sunlight is important forphotosynthesis. Photosynthesis helps to place oxygen inthe water and is important for the health of a river.
Who lives in a watershed?A. Only those people who live next to a water body.B. EveryoneC. People who live within 5 miles of a water body.D. None of the above.
The correct answer is B.Everyone lives in a watershed.A watershed is the land area thatwater moves through and drains intoa body of water.When it rains water runs downhill intosmall creeks that run into biggerstreams and then into rivers until itreaches the ocean. We all live in a watershed, no matter where we live. And we all have an impact on the river.
Correct.When it rains water runs downhill intosmall creeks that run into bigger streamsand then into rivers until it reaches theocean or a gulf.We all live in a watershed, no matterwhere we live. And we all have an impacton the waterways.
What contributes to algaeblooms in a river?A. Over fertilizing lawns and landscapesB. Stormwater draining into waterwaysC. Warm temperaturesD. All of the aboveE. None of the above
The correct answer is D.All of the above.In warmer weather, algae blooms can occur.They are often caused by the overuse ormisuse of fertilizers on landscapes. Thisfertilizer and other sources of nutrients runinto our waterways after a rainfall.
You’re right.Everyone needs to be careful to• Follow label directions when using fertilizers• Not apply near or along the edges waterways• Use slow-release fertilizers• Apply only the amount needed by the plants
How can you and your dog helpprotect our waterways?A. Don’t walk your dog near a waterway.B. Collect the dog’s waste in a plastic bag and put it in a storm drain.C. Pick up after your dog and dispose of the waste properly.D. All of the above.

Right answer.Remember, proper disposal meansplacing it in a trash can not down astorm drain.
What is the most common waytrash enters our waterways?A. After a rain, trash moves to a storm drain and empties into a water body.B. Trash blows out of a trash can or dumpster.C. Trash is thrown directly into a water body.D. All of the above
That’s not right. The correct answer is A. After arain, trash moves to a storm drain and emptiesinto a water body.It is important that only rain go down a stormdrain.• Pick-up any litter you find.• Never put lawn clippings or used motor oil down a storm drain. • All storm drain eventually lead to our waterways.
You’re right.It is important that only rain go down a stormdrain.• Pick-up any litter you find.• Never put lawn clippings or used motor oil down a storm drain.• All storm drain eventually lead to our waterways.
What is the relationshipbetween leaky car fluids and ariver otter?A. Both can be found in the river.B. Both can be wet and slippery.C. Both are brown.D. All of the above
Both river otters and leaky car fluids, such as oil, gasoline, orThe correct answer antifreeze, can be found in ouris D. All of the waterways.above. By maintaining our cars properly and repairing leaks as soon as possible, we can prevent these types of pollutants from getting in our waterways.
You’re right.By maintaining our cars properly and repairingleaks as soon as possible, we can prevent thesetypes of pollutants from getting in our waterways.Everyone plays a part in protecting our river andwaterways.
