6. Sınıf İngilizce: The world of science Çözümlü Örnekler
Örnek 1:
Look at the picture of a scientist in a lab. What is she wearing to protect herself? 🧑🔬
A) A hat
B) A lab coat
C) A scarf
D) A helmet
A) A hat
B) A lab coat
C) A scarf
D) A helmet
Çözüm:
- The scientist is in a laboratory.
- Laboratories often have chemicals and experiments.
- Scientists wear special clothing to stay safe.
- A lab coat is a common protective garment for scientists.
Örnek 2:
Which of these is a tool used by scientists to see very small things? 🔬
A) A telescope
B) A microscope
C) A magnifying glass
D) A camera
A) A telescope
B) A microscope
C) A magnifying glass
D) A camera
Çözüm:
- Scientists study many things, including tiny organisms and cells.
- To see these small things, they need special tools.
- A telescope is used for looking at stars and planets.
- A camera takes pictures.
- A magnifying glass makes things look bigger, but a microscope is much more powerful.
Örnek 3:
A scientist is mixing two liquids. One liquid is red and the other is blue. When she mixes them, the new liquid turns purple. What scientific concept is this an example of? 🧪
A) Gravity
B) Magnetism
C) Chemical reaction
D) Photosynthesis
A) Gravity
B) Magnetism
C) Chemical reaction
D) Photosynthesis
Çözüm:
- When different substances are combined and change into something new, it's often a chemical reaction.
- Gravity is the force that pulls things down.
- Magnetism is about magnets attracting or repelling.
- Photosynthesis is how plants make food using sunlight.
- Mixing red and blue paint to make purple is a simple example of how colors can mix, but in science, when liquids change properties, it's a reaction.
Örnek 4:
Imagine you are baking a cake. You mix flour, sugar, eggs, and milk, and then bake it. The batter turns into a solid cake. Is this a science experiment? Explain why or why not. 🎂
A) Yes, because you are mixing ingredients.
B) No, because it's just cooking.
C) Yes, because you are observing a change.
D) No, because you don't wear a lab coat.
A) Yes, because you are mixing ingredients.
B) No, because it's just cooking.
C) Yes, because you are observing a change.
D) No, because you don't wear a lab coat.
Çözüm:
- Science involves observing the world and trying to understand how it works.
- Baking involves combining ingredients (like a chemical reaction) and applying heat (changing temperature).
- You observe a change from liquid batter to solid cake.
- These are all aspects of scientific observation and process.
Örnek 5:
A scientist is studying the weather. She uses a thermometer to measure the temperature and an anemometer to measure wind speed. What is the main goal of her study? ☁️
A) To invent new medicines
B) To understand and predict weather patterns
C) To build taller buildings
D) To explore outer space
A) To invent new medicines
B) To understand and predict weather patterns
C) To build taller buildings
D) To explore outer space
Çözüm:
- The scientist is using tools related to weather: a thermometer (temperature) and an anemometer (wind speed).
- These measurements help us understand the current weather conditions.
- By collecting this data over time, scientists can identify patterns and make forecasts.
Örnek 6:
Ayşe wants to know if plants grow better with more sunlight. She takes two identical plants. Plant A is placed on a sunny windowsill, and Plant B is placed in a dark closet. She gives both plants the same amount of water every day. After two weeks, she observes that Plant A has grown taller and greener than Plant B.
What is the independent variable in Ayşe's experiment? 🌿
A) The amount of water
B) The height of the plants
C) The amount of sunlight
D) The color of the plants
What is the independent variable in Ayşe's experiment? 🌿
A) The amount of water
B) The height of the plants
C) The amount of sunlight
D) The color of the plants
Çözüm:
- In an experiment, the independent variable is the factor that the scientist changes on purpose to see its effect.
- The dependent variable is what is measured to see if it changes because of the independent variable.
- In this experiment, Ayşe is changing the amount of sunlight each plant receives.
- The amount of water and the type of plants are kept the same (controlled variables).
- The height and color of the plants are what Ayşe measures to see the effect of sunlight (dependent variables).
Örnek 7:
Which of these is NOT a part of the scientific method? 🤔
A) Asking a question
B) Making a hypothesis
C) Drawing a conclusion
D) Watching television
A) Asking a question
B) Making a hypothesis
C) Drawing a conclusion
D) Watching television
Çözüm:
- The scientific method is a structured way to explore and understand the world.
- It starts with observing something and asking a question about it.
- Then, scientists form a hypothesis, which is an educated guess or prediction.
- They design experiments to test their hypothesis.
- Finally, they analyze the results and draw a conclusion.
Örnek 8:
When you see a rainbow after rain, you are observing a scientific phenomenon. What scientific principle is responsible for the colors of a rainbow? 🌈
A) Gravity
B) Reflection
C) Refraction and dispersion of light
D) Evaporation
A) Gravity
B) Reflection
C) Refraction and dispersion of light
D) Evaporation
Çözüm:
- Rainbows appear when sunlight passes through water droplets in the air.
- Light is made up of different colors.
- When light enters a water droplet, it bends (refracts).
- As it bends, the different colors of light separate because they bend at slightly different angles. This separation is called dispersion.
- Gravity is the pull of the Earth. Reflection is bouncing light. Evaporation is turning into vapor.
