Интегрированный урок биология на английском языке "Flower and its structure"

The beginning of the lesson:

1. Org. moment

- Good morning dear our guests and students. Today I’m very glad to see you at our lesson.

Today we have an unusual lesson biology in English.

- You know that English is widespread language in the world and it’s business, science language. That’s why many school subjects such as biology, geography, maths and other ones are in English in many schools in Kazakhstan. Such experiment is conducted in our school.

- So, let’s start our lesson  (Slide #1)

1. Biology and its meaning

- How do you understand the word “biology”?

The word Biology is made up of two smaller words, “bio” and “logy.” Bio means life. Logy means a study of science. When we put these two words together ? Bio-logy, or Biology, the science of life.

- What can you say about living things?

Your families, friends and neighbors are also alive. Life is all around us.  Biology is the science of learning about every kind of life, no matter where it is, or how big or small it is.

1. Dividing into groups

- Such living thing is flower. So, the theme of our lesson is “Flower and its structure”

- At first let’s divide into 3 groups. Take a piece of picture and make the one.

I group – “Roots”

II group – “Leaves”

III group – “Flower”

- (Slide #2) You know that we have had lessons about leaves, root system and flower. (Slide #3) So the aim of our lesson is to show all our knowledge about flower structure, to use biological terms at the lesson and to be able to listen to the opinion of each other for the creation of working groups       

- Now each team will protect their names of groups by poster. And for this task I give you 5 minutes. (Slide #4) (Dubai miracle garden)

1. Protecting the names of groups

I group – “Roots”

Vegetative organs of plants are root, stem and leaves. Root is one of the main organs of plants. By the type of the origin and development of the roots are divided into main, lateral root and adventitious root. The main root is developed from embryonic root seed. From the main root runs lateral roots. Adventitious roots grow from the stem and leaves. Root system is divided into the tap root and the fibrous root. A tap root system is well developed the main root.  In the fibrous root system of the main root absent or stands out among the others.

II group – “Leaves”

The leaf refers to vegetative organs of plants. Leaf consists of  leaf  blade and petiole. Leaf blade is an extended part of the leaf. The base of the leaf grows and grabs your stalk on a node called vaginal leaves.  Form of leaf blades: kidney-shaped leaves, arrow-shaped leaves, the diamond-shaped leaves, heart-shaped leaves, needle-shaped leaves. Leaves with one blade are called simple leaves. Leaves having three or more of the leaf blades are called compound leaves. Among the compound leaves are distinguished: three-shaped leaves, pair pinnate leaves, not pair pinnate leaves, finger-shaped leaves.

III group – “Flower”

The conspicuous part of many flowers consists of the petals which are white or brightly coloured.  The sepals are usually small and green.  The stalk of the stamen is the filament. At the end of the filament is an anther which contains pollen grains. The female part of the flower consists of carpels. Each carpel consists of an ovary which contains an ovule which is the female gamete.  All the parts of the flower are attached to the receptacle. Nectaries are swellings, often at the base of the ovary or on the receptacle, which produce a sugary solution called nectar. Insects visit the flower and drink or collect this nectar

1. Magnifying devices

- So you know that every flower has leaves, root and flower and to see their inner structure we use magnifying devices. (Slide # 5)

- What magnifying devices do you know?

  The most common magnifying device - magnifier. It gives the increase in 3 - 5 times. A tripod  magnifier have a tripod and the subject table and give an increase in 10 - 25 times. Conventional light microscope will increase to 1500. The main part of the microscope is tube with magnifying glasses. In the upper part of the tube is installed eyepiece, at the bottom - the objective lens. On both sides of the tube there are screws settings. The tube is attached to the tripod. With the help of the screw can be lowered and to lift tube. In the center of the object table, there is a small hole, which set the rotating mirror light trap.

(explaining with light microscope)

1. The inner structure of flower

                                                                                                                                                                           - - With this light microscope we can see inner structure of leaves like this (slide #6)

- Now who wants to tell with showing what are they?

            (slide #7)

1. Fertilizers

As you know this is the inner structure of well developing leave. For normal growth and development of flower and plants we use fertilizers. One of the conditions for improving the fertility of the soil is fertilizing.

• What types of fertilizers do you know?

• What are organic fertilizers?

• What are mineral fertilizers?

Fertilizers can be divided into organic and mineral fertilizers. Organic fertilizers are substances of plant and animal origin. Mineral fertilizers are nitrogen, phosphorus and potassium.

Mineral nutrition is the uptake by plant roots of the necessary elements from the soil. For normal growth and development of plants need nitrogen, phosphorus and potassium. With a shortage of nitrogen plant is lagging behind, leaves turn yellow and fall off prematurely. With a shortage of phosphorus slows down the formation of fruits, reduced their weight. Potassium plant necessary for normal development of the roots.

VIII.      Characteristics to the flowers

So, with organic and mineral fertilizers flowers grow as beautiful as these flowers. (slide # 8) And can you tell me the names of these flowers? (Rose, tulip and snowdrop)  For each team I give one type of flower and your task is to give characteristics of them. For this task I give you 3 minutes.                  (slide #9)

IX.        Watching video

Now let’s watch the video about flowers. In this video the names of flowers and their characteristics. After the watching the video your task is to give your opinions about flowers. (slide #13)

1. Biology is the science of language
2. Only trees have root system
3. All plants have leaves
4. The fibrous root is well developed the main root
5. Leaves can be with petiole and without petiole
6. The petals of flower are only yellow.
7. All the parts of the flower are attached to the petal
8. Magnifier gives the increase in 10-25 times
9. Light microscope give the increase to 1500
10.  On the both side of the light microscope there are the objective lenses.
11.  Leaves have only upper epidermis
12. Mineral fertilizers are the substances of plant and animal origin
13. Organic fertilizers are nitrogen, phosphorus and potassium
14. There are only red tulips in the world.
15.  The roses lie under the snow and grow in the early spring

XI.      Reflection                                                  

Have we reached to the aim of our lesson? What emotion do you feel? (slide# 14)
