What is Science?

What is Science?

Science is the study of the world around us. It helps us understand how things work, why they happen, and how we can use this knowledge to improve our lives.

Key Concepts

Observation: This is when we look at things carefully and take note of what we see. For example, if you see a flower, you might observe its color, shape, and size.

Example: When you see a butterfly, you might observe its colorful wings and how it flies from flower to flower.

Experiment: This is when we try something to see what happens. For example, if you want to know if a plant grows better with sunlight or without, you can do an experiment by placing one plant in sunlight and another in the shade.

Example: You can experiment by watering two plants the same amount but giving one plant more sunlight than the other to see which one grows taller.

Hypothesis: This is an educated guess about what might happen. For example, before doing an experiment, you might guess that the plant with more sunlight will grow taller.

Example: Before your plant experiment, you might hypothesize that the plant with more sunlight will have bigger leaves.

Conclusion: This is what we learn after doing an experiment. For example, after your plant experiment, you might conclude that plants need sunlight to grow well.

Example: After your experiment, you might conclude that plants grow taller and have bigger leaves when they get more sunlight.

Why Science is Important

Science helps us solve problems, make discoveries, and create new things. It also helps us understand the world better, which is important for making good decisions.

For example, knowing about germs helps us understand why we need to wash our hands to stay healthy. Understanding gravity helps us know why things fall down instead of up.

Science is all around us, and by learning about it, we can make our lives better and help others too.
