Target group

Student of the fifth grade

Core curriculum

General requirements

II. Skills and application of knowledge in practice.

4 . Determining relationships and dependencies between particular elements of the natural, socio‑economic and cultural environment, formulating theorem on regularities, making generalizations.

Specific requirements

III. Lands and oceans on Earth: the distribution of lands and oceans, the first geographical expeditions. Student:

2) lists the names of continents and oceans and indicates their location on the globe and world map, and determines their position relative to the equator and the prime meridian;

Purpose of the lesson: The student learns the classification of sea waters on Earth.

Success criteria

• you will point the oceans on the globe;

• yuo will tell and describe the basic types of seas;

• you will show examples of basic types of seas on the map.

Teaching measures

• computers with internet access, or tablets;

• multimedia resources contained in the lesson „Types of seas and characteristics of marine waters” in the e‑textbook;

• interactive whiteboard / blackboard, marker / chalk.

Methods and forms of work

• feeding methods: information lecture;

• problem methods: didactic discussion, brainstorming;

• programmed methods: using a computer, using an e‑manual;

• practical methods: expert tables method, exercises concerned;

• forms of work: individual work, in pairs, in groups and collective.

Lesson plan

Preliminary

1 . Before class, the teacher instructs students to get acquainted with all the material from the lesson „The Global Ocean and types of seas” in the abstract.

2 . In class, the teacher determines the purpose of the lesson, informing students about its planned course.

Realization

1 . The teacher informs students that all oceans and seas on Earth are all‑global. He writes this concept on the board and asks students to write around the known names of the oceans and seas during brainstorming. After the creative phase, ideas are verified.

2 . The teacher runs Google maps and asks willing / selected students to search all the oceans one by one. Together with the class, it discusses their location, and explains the different types of ocean classification.

3 . The teacher then discusses particular types of seas (open seas, marginal seas, island seas, mediterranean intercontinental seas, mediterranean intracontinental seas).

4 . The teacher divides the class into 5 groups. It informs that their task will be to find and mark the different types of seas with the appropriate color on the world map. He assigns one type to each group. After expiration of the appointed time, the teacher displays on the interactive whiteboard exercise 1, and the representatives of the groups present the results of the work. The teacher watches over the correctness of the task.

5 . Work in groups of 5 people using the expert tables method. Pupils implement this method with the content of command 1 from the lesson in the e‑textbook. In each group there is one person who is responsible for finding one of the basic types of seas on the hypsometric map. Students from different groups who have to find the same type of sea, sit together and discuss the characteristic features of the sea and look for at least a few examples. Then they return to their groups and share their knowledge with them. At the end of the work, each group should indicate one example:

• open sea;

• marginal sea;

• island sea;

• mediterranean intercontinental sea;

• mediterranean intracontinental sea.

6 . Individual work or in pairs. Students carry out interactive exercises aimed at improving the ability to identify major types of seas.

Summary

1 . Summary of lessons in the form of an open discussion, which serves to consolidate the message, explain students' doubts and complete the notes.

The following terms and recordings will be used during this lesson

The Global Ocean and types of seas

The Global Ocean - an area of all oceans and seas connected to each other, covers about 71% of our planet's surface. Thanks to the combination of waters, their level is basically the same. However, various factors may cause short‑term or periodic changes of this level in certain parts of the Global Ocean. There are 4 oceans separated on Earth, the boundaries of which are formed by land and formal lines marked out by humans.

We distinguish:

• The Pacific Ocean - covers almost half of the Global Ocean,

• The Atlantic Ocean - makes up 25% of the Global Ocean,

• The Indian Ocean (around 21%),

• The Arctic Ocean (around 4%).

Classifications are distinguishing 3 (the Arctic Ocean is not included) or 5 oceans (the waters around Antarctica are considered to be the Southern Ocean).

Some parts of the oceans tend to be called seas. Mostly, there are 5 main types of seas:

• open seas (without a clear border with the ocean),

• marginal seas (limited by land and archipelagos of islands or peninsulas),

• island seas (surrounded by islands)

• mediterranean intercontinental seas (limited by the shores of two continents),

• mediterranean intracontinental seas (surrounded by the land of one continent).

Sea fragments surrounded by land from three sides are called bays, and a narrowing of the water area separating two land areas – straits.
