Guest post: Teaching Kids about Frogs

We were happy to receive a guest post from Alicia Moore about how to teach children about amphibians. Alicia has always loved to learn and is working toward earning a teaching degree. She is particularly interested in how the advent of the Internet and technology are changing the educational landscape. When she is not exploring the future of education, Alicia enjoys writing about literature, languages, and online resources for teachers.

While it may sound surprising, the greatest threat to any animal on the planet is mankind. Humans are perched solidly at the top of the food chain, and our nation’s youth must understand the incredible responsibility that comes with that power. This responsibility, however, doesn’t end at protecting magnificent animals like tigers and whooping cranes. Even little creatures like amphibians are worthy of our help. Luckily, you can easily teach kids about endangered or threatened frogs and amphibians by talking openly with your students about the threats frogs face and what can be done to help them.

According to the National Wildlife Federation, nearly thirty percent of all the amphibians in the world are facing extinction. Many frogs species live in the United States, and you can easily teach your students about the choices made by man that have resulted in the near destruction of these animals. You can also discuss the fact that the damage has not always been intentional, making it even more important for people to carefully consider the full consequences of their choices on the environment.

One example is the Sierra Nevada yellow-legged frog, which has seen a 90 percent drop in numbers in recent years. Part of the problem has been pesticides that wash in from surrounding farms and private properties. Suggesting that people quit using chemicals on their yards may land you in trouble with parents, but you can safely mention that there are environmentally-friendly options available for lawn care. Another issue harming the Sierra Nevada frog is the introduction of non-native trout to the lakes these frogs once called home. As the trout population has exploded, the frog population has plummeted. This provides your students with a clear example of why critters from one area should not be moved to another.

Another is the dusky gopher frog, which could once be found along the Gulf Coast from Alabama to Louisiana. Over the years, this frog’s territory range has decreased so much that it is now only found in a few breeding ponds located in southern Mississippi. The biggest challenge faced by these frogs is that they depend on the burrows created by gopher tortoises to survive, but these animals are also an endangered species. Thus, these frogs serve as a prime example of the circle of life, cascading results, and unintended consequences. As one seemingly insignificant animal is driven to extinction, another animal that depended on it will also perish.

There are also a few success stories among the endangered species of amphibians. The National Wildlife Foundation reports that the Amargosa toad is one such example. The Amargosa toad depends on springs and ponds in the Oasis Valley of Nevada. Most of these highly valued water resources are privately owned, a fact that could severely hamper conservation efforts. However, landowners in the region have willingly worked with wildlife agencies to preserve or create and maintain the toads’ habitats. The partnership has resulted in positive results for the toad, and the realization that private owners and conservation groups can work hand-in-hand to prevent the extinction of animals. This is a valuable lesson for students, as it teaches them to find ways to work together for the greater good and the benefit of creatures who are at man’s mercy.

These are just a few examples that you can use to teach students in the classroom about amphibians and the importance of protecting them. These critters are all native to different regions of the United States, and you can find wonderful pictures of them at the National Wildlife Federation’s website. The lessons can easily focus on habitat protection, not moving animals from one environment to another and finding ways to work as a team to help the animals.

Keep in mind that it may be hard for your students to understand why frogs matter in the beginning. There may be many jokes about how slimy they are, and depending on the grade level, there may even be jokes about having frog legs for dinner. As a result, you must be prepared to teach your students about the importance of frogs and amphibians. You can find a variety of lesson plans and materials online, such as this one: Frog Unit Study: Hopping to Learn. Likewise, The Amphibian Rescue and Conservation Project is another excellent resource that can help you explain the importance of frogs to your students.

If your students would like to get actively involved, you can provide them with an opportunity to do so as a class. In fact, PBS even has a website, Give and Get Back!, dedicated to volunteering and offering suggestions for how children can get more involved and make a difference. This site can help you and your students turn the concept of volunteering and making a difference into a concrete reality.

The first step in educating students about endangered amphibians is to show them the pictures available online and talk to them about why the creatures are now struggling to survive. It’s important to connect the dots between the actions of man and the unintentional habitat destruction that can result. It’s important for children to know how different actions by humans could have resulted in a more favorable outcome for the creatures.

How far can a frog jump?

This morning at the library I found a recently published book called FROGS: The Animal Answer Guide by herpetologists Mike Dorcas and Whit Gibbons (Johns Hopkins University Press, 2011). The book is structured in the form of questions and answers, helping readers gain insight into amphibians and raising awareness about the importance of frogs and toads in our natural world.

FROGS: The Animal Answer Guide by Mike Dorcas and Whit Gibbons

Here are some questions posed in the book:

Do frogs sleep?

What color are a frog’s eyes?

How do some frogs stick to walls?

Why should people care for frogs?

What roles do frogs play in native cultures?

Do frogs have teeth?

The answers are easy to read and non-technical. While the book wasn’t shelved in the children’s room, it would be fine for kids ages 10 and up.

So here’s one question from the book:

How far can a frog jump?

Many frogs can jump at least 30 times their body length, and some smaller species of tree frogs can jump 50 times their length. This is the human equivalent of jumping the length of a football field without a running start. Some frogs in the genus Rhacophorus, flying or gliding frogs of Asia, can go even longer distances. These frogs have webbed toes that they use as parachutes to slow their fall and glide from one tree to the next, or to the ground. Jumping helps frogs avoid predators; the skeletons of some species are modified to absorb the shock when they land. Not all frogs are long jumpers. The narrowmouth toads of the southeast and or the Mexican burrowing toad can only hop a few inches.

World's Smallest Frog Discovered

Researchers have discovered two species of what may be the world’s smallest frog species. As described in the journal PloS ONE, these new species of mini, terrestrial frogs were found on the island of New Guinea, and represent not only the smallest known frog but possibly also the smallest known vertebrate species (animal with a backbone).  Both new species are members of the recently described genus Paedophryne, the four species of which are among the ten smallest known frog species. They attain an average body size of only 7.7 mm (range 7.0–8.0 mm), less than the size of an M&M.

The researchers believe that the frogs have evolved their teeny size in a unique ecological niche: the leaf litter of tropical forests that remains moist year round. The frogs eat even tinier creatures (mites etc) that most other frogs don’t exploit. They are well camouflaged among leaves on the forest floor, and have evolved calls resembling those of insects.

According to the researchers, other places in the world that also feature dense, moist leaf litter tend to possess such small frog species, indicating that amphibians are well placed to occupy this ecological niche.

Before the Paedophrynes were found, the title of “world’s smallest frog” was bestowed on the Brazilian gold frog (Brachycephalus didactylus) and its slightly larger Cuban relative, the Monte Iberia Eleuth (Eleutherodactylus iberia). They both measure less than 1cm long.

SPECIAL MENTION
This photo by Jan Knizek wasn’t easily categorized, but we wanted to give it  special mention because it poignantly tells the story of  how European Green Toads and other amphibians are losing their habitats through over development. This is one of a very few breeding sites of the toads in Prague, Czech Republic, and is currently endangered by a development project.
