Lesson plan overview

Introduction

1. The teacher hands out Methodology Guide or green, yellow and red sheets of paper to the students to be used during the work based on a traffic light technique. He presents the aims of the lesson in the student's language on a multimedia presentation and discusses the criteria of success (aims of the lesson and success criteria can be send to students via e‑mail or posted on Facebook, so that students will be able to manage their portfolio).

2. The teacher together with the students determines the topic – based on the previously presented lesson aims – and then writes it on the interactive whiteboard/blackboard. Students write the topic in the notebook.

3. Health and safety – before starting the experiments, students familiarise themselves with the safety data sheets of the substances that will be used during the lesson. The teacher points out the need to be careful when working with them.

Realization

1. The teacher asks students to perform task number 1. Students formulate a hypothesis and a research question and write them on the form in the abstract. Then they design and carry out the experience according to their idea, aimed at distinguishing porcelain from faience. They record the observations in the form. The teacher asks questions in relation to the observations recorded. It initiates a discussion, the conclusions of which students write on the form.

2. The students perform task number 2 and number 3: they answer the question in the forms. The teacher makes sure that the tasks have been correctly completed and gives feedback.

3. The teacher announces an experiment “Preparing building mortars of various composition”. He instructs his students to write a research question and a hypothesis in the form provided in the abstract. After experiment is conducted, the students note their observations and conclusions. Selected people present the results of their work.

4. Students, working individually or in pairs, carry out interactive exercises to check and consolidate knowledge learned during the lesson. Selected people discuss the correct solutions for interactive exercises. The teacher completes or straightens the statements of the proteges.

5. Students get acquainted with the content of the glossary and explain in own words the meaning of selected concepts.

Summary

1. The Students, working in small groups, create an infographic showing the issues learned during the lesson.

Homework

1. Carry out task number 5 and number 6 in the abstract.

The following terms and recordings will be used during this lesson

Terms

Texts and recordings

Keramos and stucco

• Clay is a sedimentary rock, which is the basic raw material used in the ceramic industry.

• Ceramic products are the ones manufactured by burning appropriately formed clay.

• Porcelain is white and translucent ceramics of the highest quality. Kaolin is used to manufacture it.

• Bricks are commonly used as construction materials. In order to product a regular solid brick (red brick), a moulded plastic mass made of clay, sand and water is at first dried and then burned.

• Lime mortar is a binding material used in construction which is made of slaked lime, sand and water.

• Cement is a hydraulic binding material made of mineral raw materials: limestone, clay and crystalline gypsum.

• Concrete is the basic building material, which is obtained when a mixture of cement, aggregate and water becomes set.
