Rocks, Erosion, Wildlife, and More
Rivers are a freshwater biome full of life and motion. And they make fantastic places for nature walks. Grab a bucket and a net, and let's go to the river to explore.
After a few visits to your local river, lake, or stream, you may want to learn more about what you're seeing. Use any questions you and your children have as a starting point for your study. Learn the vocabulary associated with a river or stream and use those words on your next nature walk.
Here is a great resource to start with:
- This Habitat Assessment PDF has lots of photographs, vocabulary words, and diagrams related to streams and rivers.
When you're at the river, have fun safely exploring the shallow places and the river banks.
And don't forget that the hike to and from the river is part of the experience too!
Taking along a bucket and some type of strainer can be very helpful in studying river or pond life. Scoop up some of the dirt or gravel at the bottom of the river's edge. Back on the shore, pour your dirt and water mixture through cheesecloth or nylon stocking. You may find interesting creatures or pretty rocks in the mix.
Another fun activity is to wade in the water wearing either sandals or boots and see what you can catch with a net. Take a bucket to keep your creatures alive for observation. (And be sure to return them to the water after you've studied them.) Here are directions for making your own dip net.
Chart the seasons of the river. When is the water highest and lowest? When do you first spot certain flowers blooming or tadpoles?
Look for riffles -- where the water is flowing over rocks
Look for runs--where the river runs without interference.
Diagram what you see in your nature journal.
Study the riparian zone -- the land area bordering a river. Rivers with steep banks may have a riparian zone only a few feet wide. What plants grow there?

Save your rocks for a collection. You can arrange them in a glass or wooden bowl to keep on display. We like to take particularly pretty ones and spray them with clear varnish for that wet look.
Rivers & Lakes - a living book
Each river, stream, or pond has its own unique ecosystem, so you will have to find what animals exist where you play. But here are some common water animals to study. Create your own unique food chain diagram based on what you see.
