1. Objectives.

To identify an element by its symbol.
To understand how elements are arranged in the Periodic Table.
To learn the differences between atoms, elements and compounds.
To identify elements and compounds in well known and frequently used substances.

2. Contents.

- Elements and symbols.

- Periodic Table: groups and periods.

- Pure substances: elements and compounds.

- Common chemical elements.

- Common chemical compounds.

3. Language Content / Communication.

3.1.- Vocabulary.

- Nouns: atomic mass/number, periodic table of elements, property, gap, column, period, group, layer, noble gases, bioelement, trace element, room temperature. Common chemical compounds (sulphuric acid, hydrochloric acid...)

- Adjectives: challenging, outer, average, primary, secondary...

- Verbs: discover, face, sort, attempt, provide, arrange.

- Prepositions: according to.

3.2.- Structures.

Passive voice (recognition: ..are formed by…, are called…, ...were discovered…, ...is used to/as..).
Such as…,
It plays a role/a part in.., it is present in…, It contributes to…

3.3.- Discourse type.

Narration, exposition and description.

3.4.- Language Skills.

Reading, listening and speaking.

4. Contextual (cultural) element.

To know the importance of the elements in our daily life: not all chemicals

are dangerous or belong to labs.

5. Cognitive (thinking) processes.

To analyse data that appear on labels such mineral water,

disinfectants, hydroalcoholic gels, etc...

6. Tasks.

- To get familiar with the periodic table: symbols and name of the elements

(activities 1 and 2).

- To learn the history of the periodic table (activity 3).

- To learn the structure of the periodic table (activity 4).

- To find elements and compounds at home (activity 5).

- To choose a substance and present its characteristics

to the classmates (final task).

7. Activities.

Activity 1: worksheet with the origin of the name of the elements. Students must match each name with a given clue. Group of 3-4 students.

Activity 2: Elements bingo.

Activity 3: presentation that includes videos from the Internet (teacher).

Activity 4: worksheet with the periodic table. Students must write down the key facts (columns, periods, groups…).

Activity 5: read the textbook (information related to Common chemical elements and compounds).

Final task: make a presentation (in pairs) about a substance using TIC. It will be evaluated by the teacher and also by the classmates (rubric).

Review activities:

Kahoot!: Each group will choose 3-4 questions to be included in a Kahoot! Game that will be played at the end of the lesson.

QUExt: Periodic Table.

8. Methodology.

8.1.- Organization and class distribution / timing.

The variety of activities will allow different styles of learning, trying to make each student the main protagonist in the process. They will work in small groups, in pairs (at home and in the classroom), individually and as a whole group.
