Introduction
From this material students can learn about the silicate industry and production.
The students are supposed to watch video materials and answer a series of questions.
After the questions are filled in, they should check their answers and estimate their knowledge on this subject.
Task
The objectives are to learn about the silicate technologies from video materials and then answer a series of questions based on this material.
The questions require a ''Yes'' or a ''No'' answer. If the question is answered with a ''No'', then, please, correct the question so the answer would be correct.
Process
The students must watch video materials and afterwards answer these questions.
The questions:
- By manufacturing the silicates which are found in nature you can get ceramics, cement and glass?
- Is silicate manufacturing one of the oldest manufacturings?
- Is dolimite the raw material of ceramics?
- Is clay and chalkstone the substance of cement?
- Are the raw materials of cement frozen in order to get the product?
- Does the manufacturing of cement consist in 4 stages?
- Do the raw materials of glass consist only of sand?
- Are the raw materials of glass heated to get the product?
- Does the manufacturing of glass consist in 6 stages?
- Can the silicates be reproduced?
Evaluation
By answering each of these questions correctly the students can gather 20 points, meaning 2 points for each question. If the negative answers do not have a correction, the student recieves only 1 point.
The answers:
- Yes.
- Yes.
- No, clay is the raw material of ceramics.
- Yes.
- No, they are being scorched.
- Yes.
- No, there is also chalkstone and calcined soda.
- Yes.
- No, in 5 stages.
- Yes.
Conclusion
The scores of the tests:
22-25 Excellent. Have understood the subject and the tasks very well.
21-18 Well done. Done the job with slight mishaps, but overall understood the subject.
