Step-by-step solution for: Environmental Science - Class 1: Five Senses Worksheet 3 | WWF
The image you uploaded appears to be a "True or False" worksheet related to the five senses. Below is the solution and explanation for each statement:
---
Worksheet: True or False (Five Senses)
#### Instructions:
Mark each statement as True or False based on your understanding of the five senses.
---
Statements and Solutions:
1. Our eyes are the only sense that can detect light.
- True
- Explanation: The eyes are responsible for detecting light, which allows us to see. No other sense can directly detect light.
2. Our ears are the only sense that can detect sound.
- True
- Explanation: The ears are responsible for detecting sound waves, which allows us to hear. No other sense can directly detect sound.
3. Our nose is the only sense that can detect smells.
- True
- Explanation: The nose contains olfactory receptors that detect chemical molecules in the air, allowing us to smell. No other sense can directly detect smells.
4. Our tongue is the only sense that can detect taste.
- True
- Explanation: The tongue has taste buds that detect chemicals in food, allowing us to taste. No other sense can directly detect taste.
5. Our skin is the only sense that can detect touch.
- True
- Explanation: The skin contains various receptors that detect pressure, temperature, pain, and other tactile sensations, allowing us to feel touch. No other sense can directly detect touch.
6. Our eyes can detect colors.
- True
- Explanation: The eyes contain photoreceptor cells called rods and cones. Cones are responsible for detecting colors, while rods detect light and dark.
7. Our ears can detect vibrations.
- True
- Explanation: Sound is a form of vibration, and our ears detect these vibrations through the eardrum and inner ear structures.
8. Our nose can detect odors.
- True
- Explanation: The nose detects odors by sensing chemical molecules in the air, which are then interpreted by the brain as different smells.
9. Our tongue can detect flavors.
- True
- Explanation: The tongue detects flavors through taste buds, which respond to chemicals in food and drink.
10. Our skin can detect temperature.
- True
- Explanation: The skin contains thermoreceptors that detect changes in temperature, allowing us to感知 hot and cold sensations.
11. Our eyes can detect movement.
- True
- Explanation: The eyes can detect motion by tracking changes in the visual field over time.
12. Our ears can detect pitch.
- True
- Explanation: The ears can detect the frequency of sound waves, which determines the pitch we perceive.
13. Our nose can detect gases.
- True
- Explanation: The nose can detect certain gases by sensing their chemical properties, such as ammonia or carbon dioxide.
14. Our tongue can detect sweetness.
- True
- Explanation: The tongue has specific taste receptors that detect sweetness, along with other tastes like sour, salty, bitter, and umami.
15. Our skin can detect pressure.
- True
- Explanation: The skin contains mechanoreceptors that detect pressure, allowing us to feel touch and texture.

Final Answer:
- All statements are True.
$$
\boxed{\text{All True}}
