G. Long Answer Questions – With Answers

1. Explain the scientific method with an example.
   The scientific method begins with observation, then asking a question, guessing an answer (hypothesis), testing it, and checking results.
   Example: If your pen stops writing, you first observe the problem, ask why it happened, guess that the ink is finished, check it, and confirm your answer.
2. Describe how science is everywhere around us.
   Science is present in nature (plants growing, stars shining), in our homes (cooking, boiling water), and in space (planets, galaxies). It helps us understand changes, movement, and materials around us. Science is all around us.
3. Why do scientists work together in teams?
   Scientists work together because big questions need many ideas, observations, and experiments. Working in teams helps share knowledge and discover new things faster.

H. Application-Based Questions – With Answers

1. Your pen stops writing. Describe how you find the reason using the scientific method.
   • Observe the pen.
   • Ask: Why did it stop writing?
   • Guess: The ink is finished.
   • Test: Open the refill and check.
   • If wrong, guess again: Ink dried or nib blocked.
   • Try cleaning the nib.
     This is the scientific method.
2. You see clouds gathering. What “why” questions can you ask? How will you find answers?
   • Why are clouds forming?
   • Will it rain soon?
     I can observe the sky, watch weather changes, or ask an elder/teacher. This helps me find answers scientifically.

I. Higher Order Thinking Questions – With Answers

1. Why do new discoveries sometimes change old ideas?
   Because new evidence can prove that earlier beliefs were incomplete or incorrect.
2. If you could explore any mystery, what would it be and why?
   (Sample answer) I would explore how galaxies formed because the universe is full of secrets.

J. Activity Questions – With Sample Answers

1. Write about a problem you solved using thinking and observation.
   When my bottle leaked, I observed the cap and found the rubber ring was loose. I fixed it.
2. Describe a situation where someone used the scientific method at home.
