ACTIVITY 1: INTRODUCTION
a) Objectives Introduce the topic of the lesson and to raise students' interest b) Content Wonderful nature
Task 1. What can the animals or the leaves in the pictures do that people can't? Name some things people have invented to make up for what they cannot do. Discuss your ideas with a partner and then read the text.
c) Products Suggested answers
People often use the natural world as inspiration for their inventions. By observing animals and plants, they design new products to serve humans. Here are some examples.
Animals can do many things humans cannot, like flying or staying underwater for a long time. The aeroplane, with its swings and shape imitating those of a bird, is one of the greatest inventions in our
history. Thanks to it, people can travel long distances in the air. This has helped to develop trade and tourism. The submarine, which can travel
underwater, imitates a dolphin's shape. Submarines are very useful for scientists to learn about the undersea world. Plants around us are also great sources of ideas for other wonderful inventions. The self- cleaning glass window and the fabric used to make umbrellas are both inspired by the smooth leaves of a lotus plant, with their ability to wash away dirt in the rain. Another product is Velcro. This hook- and-loop fastener was invented after a Swiss engineer observed how the seeds of a plant clung to his clothing. He then made two fabrics stick together thanks to the hooks on one surface and the loops on the other. Since then, Velcro has gradually become a familiar fastener for shoes, jackets, and even spacesuits.
It is definitely true that nature has inspired numerous inventions and technologies. Scientists and inventors have tried to imitate something in nature in an effort to create better, stronger, safer tools and devices for our everyday life.

Organization - Step 1- Assigning
State the requirements for each activity for the students. Make sure the students have a clear understanding of the task for each activity before performing the task.
- Step 2- Performing
Students work individually, in pairs, or in groups in the process of performing tasks. Teachers do general observations and help if necessary.
- Step 3- Reporting and discussing
Ask a few students or group representatives to present their answers. Other groups comment. Teacher general comments.
- Step 4: Concluding
Teacher presents specific learning products that the student must complete as required and clarify the problem to be resolved / explained; Learning tasks must be performed next.
ACTIVITY 4: APPLICATION
a) Objectives Students apply the knowledge they have just learned into communicative and practical situations
b) Content Task 5. Which of the four inventions mentioned in the text is the best imitation of nature? State your reasons.
c) Products Suggested answers
