State whether True or False :
Question 1: Science is defined primarily as a way of memorizing facts and figures about different topics.
Question 2: When water is cooled, it freezes and turns into ice, and when it is heated, it boils and becomes steam.
Question 3: Curiosity is described as the most important element needed for the "big adventure" of science.
Question 4: Scientists generally work alone because scientific discovery requires singular focus and individual effort.
Question 5: The scientific method includes forming a hypothesis and conducting experiments before analyzing the results.
Answer 1: False. (Science is a way of thinking, observing, and doing things to understand the world and uncover its secrets. It is a step-by-step process to find answers, and is not just about memorising facts and figures).
Answer 2: True.
Answer 3: True.
Answer 4: False. (Science is rarely done alone, and scientists across the world often work together in large teams. Teamwork helps them tackle complex problems and make discoveries more exciting and effective).
Answer 5: True.
Very Short Answer Type Questions :
Question 1: What is described as the most important thing for the "big adventure" of science?
Curiosity.
Question 2: What term is used for people who follow the scientific method to solve problems or discover new things?
Scientist.
Question 3: What happens to water when it is cooled?
It freezes and becomes ice.
Question 4: What subject will students encounter as they enter the Middle Stage of school?
Science.
Question 5: What three elements does the source say science is a way of?
Thinking, observing, and doing things (to understand the world).

Short Answer Type Questions :
Question 1: What is the definition of science?
- Science is defined as a way of thinking, observing, and doing things to understand the world we live in and uncover the universe's secrets.
- It is presented as a big adventure that involves asking questions and exploring how things work.
Question 2: List and briefly describe the five steps of the scientific method.
The five steps are:
- observing something interesting or not understood;
- asking a question about the observation;
- guessing a possible answer (hypothesis);
- testing the guess with experiments or more observations;
- and analyzing the results to see if the question is answered.
Question 3: How can an ordinary person act like a scientist in their daily life? Provide one specific example.
Anyone who follows the scientific method to solve a problem is acting like a scientist. For example, a bicycle repair person trying to find where a tire is leaking air, or a person cooking who wonders why their dal spilled and guesses there was too much water, is applying the scientific method.
Question 4: What are the primary benefits of scientists working together in teams?
- Scientists work in teams to combine diverse ideas and skills, which makes the process of discovery more exciting and effective.
- This collaboration allows them to tackle complex problems more efficiently and achieve more impactful results.
Question 5: What two essential things do all organisms require for their growth?
All organisms need food and water to support their growth. These are the fundamental requirements for life.
Question 6: What human sense is typically used to understand the difference between hot and cold water?
People understand the difference between hot and cold water by using their sense of touch.
Question 7: Describe the changes that happen to water when it is cooled and when it is heated from a solid state (ice).
- When water is cooled, it freezes and becomes solid ice.
- When this ice is heated, it turns back into liquid water.
