Hakikat fisika dan prosedur ilmiah
- 1.
Berikut ini yang bukan merupakan sikap yang diharapkan dari seorang ilmuwan adalah ....
- A.
Berusaha keras
- B.
Teliti dalam mencatat pengamatan dan penemuan
- C.
Menghargai pendapat orang lain
- D.
Langsung melompat ke kesimpulan
- E.
Jujur dan terbuka
Correct Answer
D. Langsung melompat ke kesimpulanExplanation
The correct answer is "langsung melompat ke kesimpulan" because it goes against the expected behavior of a scientist. Scientists are expected to be thorough in their observations and discoveries, respect the opinions of others, work hard, be honest and open-minded. However, jumping to conclusions without proper evidence or analysis is not a characteristic of a good scientist. They are expected to carefully analyze and evaluate data before drawing any conclusions.Rate this question:

Kecakapan berikut yang bukan suatu proses kecakapan sains adalah ....
- A.
Mengevaluasi
- B.
Menduga
- C.
Merencanakan
- D.
Mengamati
- E.
Menarik kesimpulan
Correct Answer
B. MendugaExplanation
The correct answer is "menduga". This is because "menduga" means "to guess" or "to speculate", which is not a scientific process. The other options, such as "mengevaluasi" (to evaluate), "merencanakan" (to plan), "mengamati" (to observe), and "menarik kesimpulan" (to draw conclusions), are all scientific processes that involve systematic observation, analysis, and reasoning.Rate this question:

- D.
Merumuskan masalah - hipotesis - eksperimen - kesimpulan
- E.
Merumuskan masalah - eksperimen - hipotesis - kesimpulan
Correct Answer
D. Merumuskan masalah - hipotesis - eksperimen - kesimpulanExplanation
The correct answer is "merumuskan masalah - hipotesis - eksperimen - kesimpulan". This is the correct sequence of steps in the scientific method. First, a problem or question is identified and formulated. Then, a hypothesis is proposed as a possible explanation for the problem. Next, experiments or tests are conducted to gather data and evidence. Finally, based on the results of the experiments, a conclusion is drawn to determine if the hypothesis is supported or not.Rate this question:

Perhatikan pernyataan berikut! (1) Fisika sebagai produk (2) Fisika sebagai proses (3) Fisika sebagai sikap Yang merupakan hakikat fisika adalah nomor ....
- A.
(2) saja
- B.
(1) dan (2) saja
- C.

Correct Answer(s)
E. (1), (2), dan (3)
F. (1), (2), dan (3)Explanation
The correct answer is (1), (2), and (3). This is because the nature of physics encompasses all three aspects mentioned in the statements. Physics can be seen as a product, as it involves the study and understanding of the physical world and its phenomena. It can also be seen as a process, as it involves the use of scientific methods and experimentation to gather knowledge and make predictions. Additionally, physics can be seen as a mindset or attitude, as it encourages critical thinking, curiosity, and a willingness to explore and question the natural world. Therefore, all three statements (1), (2), and (3) are valid in describing the essence of physics.Rate this question:

Berikut yang bukan merupakan aturan laboratorium fisika adalah ....
- A.
Dilarang bermain-main di laboratorium
- B.
Menjaga semua peranti dan area kerja yang bersih dan rapi
- C.
Cuci tangan dengan sabun setelah selesai melakukan eksperimen
- D.
Hanya buku dan catatan yang diperlukan saja yang harus dibawa ke laboratorium
- E.
Tidak perlu membaca petunjuk praktikum, cukup dengarkan arahan guru
Correct Answer
E. Tidak perlu membaca petunjuk praktikum, cukup dengarkan arahan guruExplanation
The correct answer is "tidak perlu membaca petunjuk praktikum, cukup dengarkan arahan guru". This is because it is important to read and understand the instructions given in a practical experiment in order to ensure safety and accuracy. Simply listening to the teacher's instructions may not provide all the necessary information and precautions needed for the experiment.Rate this question:

Salah satu produk sains dewasa ini adalah Pembangkit Listrik Tenaga Nuklir (PLTN). Berikut yang termasuk keunggulan PLTN adalah ....
- A.
Teknologinya murah
- B.
Tidak ada risiko yang membahayakan
- C.
Tidak menghasilkan gas buang yang menyumbangkan kerusakan lingkungan selama tidak terjadi kebocoran
- D.
Tidak menggunakan bahan radioaktif
- E.
Tahan terhadap bencana alam
- F.
Tahan terhadap bencana alam
Correct Answer
C. Tidak menghasilkan gas buang yang menyumbangkan kerusakan lingkungan selama tidak terjadi kebocoranExplanation
PLTN memiliki keunggulan tidak menghasilkan gas buang yang menyumbangkan kerusakan lingkungan selama tidak terjadi kebocoran. Hal ini berarti bahwa PLTN tidak menyebabkan polusi udara seperti pembangkit listrik tenaga fosil lainnya. Meskipun demikian, jika terjadi kebocoran, PLTN dapat menjadi berbahaya dan menyebabkan kerusakan lingkungan yang serius. Oleh karena itu, keamanan dan pengawasan yang ketat diperlukan untuk menjaga agar PLTN tetap aman dan tidak menyebabkan kerusakan lingkungan.Rate this question:
