B4U5 Revealing nature
Starting out
FREE TALK
What animals are you interested in
Group work. Discuss the animals you are interested in.
Dolphins: The "Intelligent Social Butterflies" of the Sea
They have high emotional intelligence. They form close-knit groups (called pods) and even help injured members or other species, like rescuing humans.
They use complex communication. Dolphins make clicks, whistles, and body language to "talk"—scientists think their "language" is more sophisticated than many animals.
Tigers (from "Mammals" in Vertebrates)
Tigers are such powerful and majestic mammals. I’m amazed by how they’re top predators in their habitats, with their beautiful striped coats that help them camouflage when hunting. Also, it’s sad but important to talk about how they’re endangered, so learning about tiger conservation feels meaningful.
Butterflies (from "With 3 pairs of legs" in Invertebrates)
Butterflies are so fascinating because of their life cycle—from caterpillar to chrysalis to the colorful adult butterfly. Their wings have such intricate patterns, and they play a huge role in pollination, which is vital for many plants. It’s cool how something so delicate can be so important for nature.
What do you think the title “Revealing nature”means
reveal: to make known something that was reviously secret or unknown.
nature
n. 自然，自然界
n. 本质；特性
“Revealing nature” likely means uncovering, exploring, and making known the various aspects of the natural world. This could involve discovering how different natural phenomena work, understanding the secrets of plant and animal life (like how seeds travel, as we talked about earlier, or how animals are classified), delving into the interactions within ecosystems, or bringing to light the beauty, complexity, and hidden mechanisms that exist in nature. It’s about peeling back the layers to gain a deeper insight into the natural environment around us.
Revealing nature
What do you expect from the title
How much do you know about nature
Man selects only for his own good; nature only for that of the being which she tends.
---- Charles Darwin
Look deep into the nature, and then you will understand everything better.
---- Albert Einstein
reveal: to make known something that was previously secret or unknown
Activity 1
Look at the page from a science magazine and answer the questions.
1. What do you know about these animals
The Komodo dragon 科莫多巨蜥
The Komodo dragon is the largest lizard in the world. It can grow to three metres in length and can weigh about 135 kilograms. Despite its size and weight, it can run for short distances at up to 20 kilometres per hour.
The Duck-billed platypus
鸭嘴兽
The duck-billed platypus is a small egg-laying mammal(up to 60 cm in length)found only in Eastern Australia including Tasmania. As its name suggests, it has a mouth that looks like a duck's bill, while its thick fur and flat tail are
similar to those of a beaver.
Nautilus 鹦鹉螺
As one of the oldest sea animals in the world, the nautilus has hardly changed in about 500million years, and that is why it is often given the name “living fossil”.
2. What other similar animals do you know about Share your knowledge with the class.
Pangolin
Golden monkey
Lynx山猫，猞猁 来自拉丁语lynx词源同light因该猫科动物在黑暗中发光的眼睛而得名
