CIÊNCIAS DA NATUREZA SEM SABER A MATÉRIA!! - Estratégias ENEM 2023

Summary

In this video, Humberto shares practical tips and strategies to excel in the Science section of the ENEM exam, particularly for achieving over 40 correct answers. He emphasizes the importance of reading all details, such as footnotes and text in images, and using techniques like elimination and dimensional analysis to solve problems efficiently. Humberto also stresses the need to master and interpret physics formulas, avoid mental fatigue by alternating between subjects, and use intensive revision materials for quick recap before the exam. His lighthearted mention of the 'like' strategy adds humor while engaging viewers.

Takeaways

• 😀 Focus on reading every word in your exam, especially details in images and footnotes, as they may contain hidden clues to answer questions correctly.
• 😀 When unsure about an answer, don’t rush to choose. Reread all the options carefully before marking your final answer to avoid mistakes.
• 😀 In Physics, use dimensional analysis as a trick to solve problems without fully understanding the theory. It's a powerful method to simplify complex questions.
• 😀 For multiple-choice questions, particularly in Nature Sciences, it's crucial to read all alternatives before confirming your answer to avoid eliminating the correct one by mistake.
• 😀 Master the interpretation of physics formulas and their proportional relationships. This understanding is essential to avoid memorization traps and improve problem-solving skills.
• 😀 If you're aiming for a final review before the exam, focus on intensives that summarize key points in Physics, Chemistry, and Biology to reinforce your knowledge.
• 😀 Avoid spending excessive time on detailed, less important subjects if you have a solid foundation. Prioritize reviewing the most relevant and difficult topics for the exam.
• 😀 Break your exam into manageable chunks, alternating between different subjects (e.g., Mathematics and Nature Sciences) to keep your mind fresh and alert.
• 😀 Ensure that you review basic physics concepts, such as proportionality and how different quantities relate to each other (e.g., force and acceleration).
• 😀 For students who already know the content, try reviewing intensive, summarized courses to enhance retention and increase confidence before the exam.

Q & A

What is the main focus of the video?

The video primarily focuses on providing tips and strategies for succeeding in the 'Ciências da Natureza' section of the ENEM (Brazilian National High School Exam), especially with limited time for preparation.

What are some strategies mentioned to improve performance in 'Ciências da Natureza'?

The video suggests various strategies including reading all parts of the question carefully, using elimination techniques, and applying tricks such as dimensional analysis and knowing how to interpret formulas in physics.

Why does the presenter recommend reading the image captions in the exam?

The presenter shares an example where reading the caption in an image provided the answer to a question about infrared waves heating water. This illustrates how small details in the image can help solve problems more effectively.

What advice is given regarding how to approach difficult questions?

The video advises students to read all the options before answering, especially if they feel uncertain. This ensures that they don't eliminate the correct option prematurely and allows for more informed decision-making when revisiting the question.

How does the presenter suggest handling questions related to plant hormones like auxins?

The presenter emphasizes the importance of reading all the options carefully. In the example with auxins, the correct answer was about root formation, and careful attention to the wording could have prevented the mistake of choosing the wrong one.

What is the 'dimensional analysis' trick in physics?

Dimensional analysis is a technique where you work with units of measurement rather than theory to solve problems. By multiplying or dividing the units, students can eliminate unknowns and simplify complex physics questions without needing to fully understand the underlying theory.

Why is it important to understand and interpret physics formulas?

Understanding and interpreting physics formulas is crucial because it helps students recognize relationships between variables, such as proportionality, which are essential for solving problems in the exam. Just memorizing formulas is not enough.

What kind of review does the presenter suggest for students who have already studied the material?

For students who have already studied the material, the presenter suggests reviewing essential topics through a 'crash course' or intensive review sessions, focusing on key points in physics, chemistry, and biology to refresh knowledge before the exam.

What advice does the presenter give to avoid mistakes in mathematics during the exam?

The presenter recommends alternating between solving questions in mathematics and 'Ciências da Natureza' to avoid mental fatigue, as science questions tend to be more theoretical and can provide a break from math's more calculation-heavy nature.

What is the 'last-minute' strategy mentioned by the presenter for students aiming to score well in 'Ciências da Natureza'?

The presenter humorously suggests that students who like the video may have their scores improved, hinting at a playful 'secret' from a contact in the Ministry of Education. While not a real strategy, this emphasizes the importance of engagement and staying positive.
