LESSON STRUCTURE

Greet the class.

Ask four or five students to respond.
Review
1)Homework check.
2)Choose some students to present their Garden Plan.
3)Review the vocabulary and concepts from the last lesson. Make a list on the board of things you need to make your garden grow as a class.
KEY CONCEPTS FOCUS STRUCTURES: It grows in eastern Asia.
When something touches this plant's leaves, they close up tightly.
After a few minutes, the leaves open up again. This plant is fun for small children to play with. When people first hear it laughing, they are usually quite surprised and begin to laugh along with the tree.
It grows in the middle of Africa.
Its two leaves continue to grow for its whole life. This plant can live as long as 1 500 years, so people call it a living fossil.
STEP 1: Present
CLASS WORK: Think About It
1)Divide the class into groups to discuss the Think About It questions. Then have each group share their answers with the class.
Teacher: What is a plant
Students: A plant can be a flower, tree, bush, vegetable, fruit or grass.
Teacher: Good work. How many plants can you name
In their groups, have the students make a list of plants they know. Ask the groups to share their answers with the class and create a list of plants on the board. Students may look up words in the dictionary to help them answer this question.
Teacher: What do you think makes a plant special Students: A special plant is something that is not common. It is a plant that you don't see every day. Teacher: That's right. Do you think grass is a special plant
Students: No.
Teacher: Right. I agree. Grass is a very common plant. How about a cherry blossom tree Do you think that is a special plant
Students: Yes. Cherry blossom trees are very beautiful and they are not so common.
Teacher: Very good. Some plants are special because they are very beautiful, but there are other plants that are special because they do interesting things that most other plants don't do. Now, with that in mind try to make a list of plants that you think are special.
Again, have the students return to their groups to make a list of special plants, and then have them share it with the class. Make a list on the board. Teacher: The title of this lesson is"Amazing Plants" because this lesson talks about plants that can do amazing things. What does the word "amazing" mean in Chinese
