My daughter found her favorite activity right away: stickers! The creature my children took the most interest in was learning about the frog! This Montessori frog puzzle was a huge highlight while learning about the anatomy of the frog. Montessori puzzles have been on my wishlist, so I was most excited about this. I was so thrilled to see an Usborne book about Tadpoles and Frogs in our life cycle kit! It gave us interesting facts, fascinating photographs, easy to understand diagrams, and it even provided detailed explanations for the many questions lingering through all of our minds.

One of our favorite facts was learning that frog eggs are also called frogspawn. A life cycle unit would not be complete without some hands-on exploration! We pulled out the ant life cycle model and ladybug life cycle models to explore. After talking about the stages of the life cycle with our life cycle charts, I put the life cycle figures in order and listened to them chant.

It is always so fun to explore life cycles, and this year was definitely one of the best.

Frog Facts for Kids

While we used this as a homeschool project this year, I absolutely plan to use many of these materials for my future preschool classes too! Brainy Kit came about when the owner, Viktoria, wanted to combine two of her passions — Montessori and affordable resources. After Viktoria opened a Montessori preschool, she had requests come in for her to expand her program. And next came Brainy Kits! It is Montessori homeschool curriculum in a box, and many materials can easily be used for the classroom too! Brainy Kits are a subscription kit service with a new, exciting kit each month.

Adult tree frogs are insectivores that eat flies, ants, crickets, beetles, moths, and other small invertebrates. However, as tadpoles, most of them are herbivores. Almost all male frogs attract mates with advertisement calls.

Each frog species has its own call so female frogs can listen for potential suitors of their own species. Some frogs hatch as miniature adults. More commonly, however, tadpoles emerge from frog eggs. As tadpoles mature, they lose their tail and grow legs until they eventually reach their adult form. The lifespan of tree frogs varies among species. Some of them are long-lived, such as the Australian green tree frog Litoria caerulea , which is often kept in captivity for upward of 15 years.

Species with lifespans of less than three years are considered short-lived. Amphibians are declining worldwide and are collectively one of the most at-risk groups for extinction.

They breathe through their skin, which makes them especially sensitive to environmental change. Threats to tree frogs include habitat destruction , pollution , climate change , and diseases like chytridiomycosis. Not all members of the tree frog family Hylidae live in trees, and not all frogs that live in trees are in the hylid family.

That day I also discovered one or two clusters of their eggs: nine or ten gelatinous balls wedged in a cavity, each about a centimetre in diameter.

Within each crystal orb, perched on a pale golden yolk, was a prominent tadpole—the only way I knew these were frog eggs. In the introduced Australian species the adult female lays a large number of tiny eggs which hatch into the small wriggling polliwogs beloved of children. These tadpoles grow a horny beak with toothlike denticles and feed on small aquatic plants particularly duckweed and moribund animals, including other tadpoles.

They possess gills for respiration and also for filtering out small organisms from turbid pond water as additional food. Changes happen inside the creature, too. Fast-moving insects replace plants in the diet. An extensile fly-catching tongue develops, along with proper jaws and some teeth.

The Poison-Arrow Frog and the Bromeliad

Eyes enlarge and eyelids form. The intestine shrinks in length. A stomach forms. Yes, tadpoles lack a stomach!

Vocal apparatus develops, to a greater extent in males than in females. Reproductive organs develop. The skin changes to protect the organism in air as well as in water. Native frogs undergo some but not all of these changes.

Since they are nourished by yolk until metamorphosis, the larvae do not go through a herbivorous feeding stage. The tongue is small and rounded, not highly extensile.

Tadpoles have only small gills, and adults lack a vocal sac. The more direct development of our native frogs seems peculiar. In southern Chile, the small Darwin frog lays eggs on moist ground, and days later attending males ingest the eggs and brood them in their vocal sacs until the young metamorphose. Females of the gastric-brooding frogs of Queensland go one step further, swallowing fertilised eggs which develop into froglets within the stomach. Production of stomach acid and digestive enzymes is temporarily turned off.

Sad to say, the two species possessing this peculiar habit, which were only discovered in the mids, are already feared extinct. Some species of frog lay their eggs in floating nests of foam which they whip up with their legs from special secretions. Other frogs place their eggs in nests of leaves hanging above water, so that when the tadpoles emerge they fall into it. Females of the flaming poison-arrow frog of tropical America transport their tadpoles, a few at a time, from the forest floor to water-filled hollows in the leaf axils of plants.

Each morning they visit their offspring and lay some unfertilised eggs, which the tadpoles devour.

Eggs for breakfast, anyone? Fertilisation in almost all frogs happens outside the body. Often his hands develop horny pads in the mating season to give a better grip, for amplexus often lasts for hours. She releases a stream of eggs which he fertilises as they are laid. While the development of our native Leiopelma frogs may not be extraordinary in frogdom, the animals themselves are. All other frogs are much more advanced.

Together with the tuatara and kiwi, Leiopelma was one of those ancient Gondwanaland groups that floated away on prehistoric New Zealand 70 million years ago and have changed little since. The features which set Leiopelma apart from most frogs are internal idiosyncrasies of the musculoskeletal system, including the persistence of relic tail wagging muscles in the adult, elongated ribs attaching to the sternum but not the vertebrae, the route that the facial nerve takes in exiting the braincase, and other details of little meaning to the non-herpetologist.

Despite the illustrious position our frogs occupy in the frog universe, only a small band of scientists pay close attention to the animals. For a long time this frog was considered identical to the Stephens Island species, Leiopelma hamiltoni. Frogs were first discovered on Maud Island in the s, and in a local priest was told of their existence. There are no possums or introduced predators on the island, which is also home to abundant lizards, giant weta introduced from Mana Island, off the Kapiti coast , and kakapo from Codfish Island, west of Stewart Island.
