"Class, this is a treefrog. It is an example of natural selection."
"Where does the treefrog live?"
"Lakes, rivers, swamps and trees near water are examples of a green treefrog habitat."
"The treefrog lives in wet places and absorbs water into skin for survival."
"Some structural adaptations God gave it are: camouflage for hiding from predators; a long tongue for catching flying prey; & webbed, sticky feet for latching onto trees; Some green treefrogs have the physiological adaptation of poison. A behavioral adaptation is being nocturnal to avoid being eaten during the day."
"The treefrog has many adaptations God gave it, including structural adaptations, physiological adaptations, and behavioural adaptations."
"How does a treefrog survive in its habitat anyway?"
That's creative design!
The grade seven science class at Regent Christian was studying evolution when, all of a sudden, a green tree frog hopped into the classroom. The science teacher took the opportunity to teach her class about one animal's particular habitat, the adaptations it needed to survive, and how the treefrog can demonstrate evolution by natural selection. Mrs. Kientz took her class a journey outside to learn more about the tree frog's life and how it survives in nature.
The treefrog uses these adaptations to find food, hide itself from predators, and to live.
"Why does the treefrog need these adaptations though?"
The class goes on an adventure into one of the treefrog's habitats, a nearby swamp.
"But what is natural selection?"
"Natural selection is an important component of evolution wherein favorable traits are aquired permanently in the organism's genetic sequence through mutations, and passed on to the next generation."
One of the students had a great question about the sorts of adaptations the green treefrog has, since she had just learned about this concept in science class.
"These favourable traits help to improve the organism's chances for reproduction and survival."
"But how are favorable traits that promote survival acquired?"
Mrs. Kientz went on to explain the purpose of the treefrog's adaptations to her class.
Then, because the students had been learning about natural selection as an evolutionary process, they wanted to know how natural selection is seen in a treefrog. First, they did a basic review of some definitions. what is natural selection anyways?
After doing some explaining, Roger had a great question!
