Which of your five senses tell you if something is hot or cold?
Correct Answer
A. Touching
Explanation
The sense of touch allows us to feel the temperature of objects, which helps us determine if something is hot or cold. When we touch something hot, our skin senses the heat and sends signals to our brain, alerting us to the high temperature. Similarly, when we touch something cold, our skin detects the lack of heat and again sends signals to our brain, indicating that the object is cold. Therefore, the sense of touch is responsible for informing us about the temperature of objects.
2.
Which of your five senses warns you not to eat rotten food?
Correct Answer
B. Smelling
Explanation
The sense of smell warns us not to eat rotten food because it can detect the presence of harmful bacteria or chemicals that indicate spoilage. When food starts to rot, it releases certain compounds that have a distinct unpleasant odor. Our olfactory system is designed to recognize and interpret these smells as a way to protect us from consuming potentially harmful substances. By relying on our sense of smell, we can avoid eating rotten food and prevent potential food poisoning or other health issues.

On what part of the tongue do you best taste sweet foods?
Correct Answer
B. The front of the tongue
Explanation
The front of the tongue is where taste buds that are most sensitive to sweet flavors are located. These taste buds have receptors that are specifically designed to detect and respond to the presence of sugars, allowing us to perceive sweetness. The sides and back of the tongue also have taste buds, but they are more sensitive to other flavors such as sourness or bitterness. Therefore, the front of the tongue is where we best taste sweet foods.
4.
In what part of the eyes do light rays go into?
Correct Answer
B. Pupil
Explanation
Light rays enter the pupil of the eye. The pupil is the black circular opening in the center of the iris. It controls the amount of light that enters the eye by contracting or dilating in response to the brightness of the environment. When the pupil constricts, less light enters the eye, and when it dilates, more light enters. This allows the eye to adjust to different lighting conditions and protect the sensitive retina at the back of the eye.
5.
Which is an example of a low sound?
Correct Answer
A. Drum
Explanation
A drum is an example of a low sound because it produces a deep and resonant tone. The sound of a drum is characterized by its low frequency and strong vibration, which creates a booming and bass-like sound. In comparison, a flute and whistle produce higher-pitched sounds.
6.
Which of your five senses help you to listen to something?
Correct Answer
B. Hearing
Explanation
Hearing is the correct answer because it is the sense that allows us to perceive and interpret sound. When we listen to something, our ears receive sound waves and transmit them to the brain, where they are processed and interpreted as meaningful sounds. Touching and smelling are not directly related to the act of listening.
7.
Which is the largest sense organ that covers the entire human body?
Correct Answer
A. Skin
Explanation
The skin is the largest sense organ that covers the entire human body. It is responsible for detecting sensations such as touch, heat, cold, and pain. The skin also plays a crucial role in protecting the body from external factors such as pathogens and UV radiation. It contains numerous sensory receptors that allow us to perceive the environment around us and interact with it. Additionally, the skin helps regulate body temperature and is involved in the production of vitamin D.
8.
Ears are made up of two parts. What are they?
Correct Answer
A. Outer ear and Inner ear
Explanation
The ears are made up of two main parts: the outer ear and the inner ear. The outer ear consists of the visible part of the ear, known as the pinna, and the ear canal. Its main function is to collect sound waves and direct them towards the middle ear. On the other hand, the inner ear is located deep within the skull and contains the cochlea, which is responsible for converting sound vibrations into electrical signals that can be interpreted by the brain.
9.

10.
The transparent outer layer of the eye that helps in viewing things is called ____________.
Correct Answer
C. Cornea
Explanation
The cornea is the transparent outer layer of the eye that helps in viewing things. It acts as a protective covering for the eye and also plays a crucial role in focusing light onto the retina. The cornea is responsible for about two-thirds of the eye's total focusing power. It allows light to enter the eye and helps to refract or bend the light rays so that they can be properly focused on the retina, allowing us to see objects clearly.
