Practical work No. 1:Familiarization with laboratory equipment.

Rules for safe work in a chemical laboratory

Purpose and objectives of the lesson:familiarize students with safety rules when working in a chemical laboratory, teach them basic techniques for working with chemical glassware, a laboratory stand, an alcohol lamp or a gas burner.

Equipment:

on the students' tables there is a laboratory stand with accessories, test tubes, flasks, an alcohol lamp, porcelain cups, matches, a cap for extinguishing an alcohol lamp, a glass tube, and tongs. On the demonstration table is a set of laboratory glassware (conical, flat-bottomed and round-bottomed flasks, beakers, beakers, funnels).

During the classes:

T: Conducts an introductory conversation about the need to comply with safety rules when working in a chemistry room.

SH: work independently with the textbook

T: talks with students to analyze and specify safety rules. Sample questions for conversation:

Why can’t you take more substances than indicated in the instructions?
Is it possible to empty and pour unused substances back into the bottle?
Why can’t you take substances from jars with a wet spoon?
What should you do in case of a burn, cut, or contact of caustic or hot liquid with your skin?
Why is it necessary to use only clean dishes?
How to correctly determine the smell of substances?
How should bottle stoppers be placed on the table?
Is it possible to taste substances?
What quantity of substances should be taken if this is not indicated in the instructions?
Where should the opening of a test tube with liquid be directed when heated?

Sh: answer questions, discussing them with the teacher.

U: gives instructions for carrying out practical classes. Explains in detail how to keep notes in notebooks for practical work, and how to format your work. Gives a sample design practical work: Number and title of practical work.

Equipment, materials.

U: justifies the need to know the structure of laboratory equipment and how to handle it.

D: demonstrated different kinds laboratory glassware: round-bottomed, flat-bottomed, conical, volumetric, Wurtz flasks; chemical funnels, drip funnels, separating funnels; pipettes are simple, calibrated;

burettes, graduated cylinders, beakers, Kipp apparatus, test tubes.

T: names all the items on display, gives a brief comment (features of use, purpose of the utensils).

Ш: record the names and schematically sketch the types of chemical glassware in a notebook.

T: explains the structure of a laboratory tripod and how to work with it.

Sh: work independently with a tripod and its accessories. Assemble and disassemble the stand, secure the test tube in it. Make appropriate sketches and notes in a notebook.

U: explains the device of a spirit lamp ( gas burner) and rules for working with it.

Sh: a) learn how to work with an alcohol lamp (burner) - light it, extinguish it, heat water in a test tube; b) study the structure of the flame. To do this you need to light alcohol burner, setting the wick at such a height that you get a not very large flame (no more than 7 cm long). Heat a glass tube 10 cm long and 9 mm in diameter in a flame, holding it with tongs. Place the tube at an angle, keeping its lower end inside the flame. Ignite the alcohol vapor escaping through the tube. All observations and actions are described in a notebook.

T: sums up the lesson.

DZ: learn safety rules, names of laboratory equipment.

Take part!

Children may find some lessons boring. And then discipline begins to suffer in class, students quickly get tired and do not want to take part in the discussion.

Case lessons were created to connect school knowledge with urgently needed competencies such as creativity, systems and critical thinking, determination and others.

Thanks to the cases, you can help the student benefit from and enjoy studying and cope with his personal problems!

Gifted children - who are they? What are abilities, what is giftedness? And how do capable children differ from gifted ones? How to recognize a gifted child? Do all children show giftedness in the same way? What advice should parents of a gifted child give when raising him or her? About this in our webinar.

Not suitable for modern students traditional methods teaching. It is difficult for them to sit over textbooks without being distracted, and long explanations make them bored. The result is rejection from studies. Meanwhile, the priority of visuality in the presentation of information is the main trend in modern education. Instead of criticizing children's craving for “pictures from the Internet,” use this feature in a positive way and start including watching thematic videos in your lesson plan. Why is this necessary and how to prepare a video yourself - read this article.
