Why is Earth round?
Why is Earth round?
The Earth is round due to gravity pulling all matter towards the center, forming a sphere (the lowest energy state).
How do stars stay in the sky?
How do stars stay in the sky?
Stars stay in the sky due to a balance between their gravity and their energy produced through nuclear fusion.
Why only mammals have hair?
Why only mammals have hair?
Mammals have hair for insulation, camouflage, and sensory functions. Hair is made of keratin, a protein.

Study Notes
Scientific Questions
- Earth's shape is due to gravitational forces that pull matter into a spherical form.
- Stars remain in the sky and maintain positions due to gravitational interactions and the dynamics of celestial objects.
- Giraffe's food takes considerable time to digest, typically around 24-48 hours, to travel through their digestive system.
- Only mammals possess hair as a characteristic feature, aiding in insulation, sensory perception, and protection.
- Humans perceive color through specialized cells in the eyes called cones, which are sensitive to different wavelengths of light.
- Humans cannot fly due to anatomical limitations such as bone structure, muscle mass, and lack of wings needed for flight.
- Oxygen is essential for human survival as it is a critical component in the process of cellular respiration, producing energy.
- Freckles result from an increase in melanin production in the skin, influenced by genetic and environmental factors.
- Ocean waves are formed primarily by wind action on the water surface, generating energy that travels across the ocean.
Non-Scientific Questions
- Preferences for colors, such as girls liking pink, can stem from cultural influences and societal norms rather than biological factors.
- Interest in sports among boys may correlate to social conditioning and cultural expectations rather than inherent abilities or traits.
- The pathway to becoming rich often involves personal choices, opportunities, socio-economic background, and sometimes luck.
- The sourness of lemons arises from their high citric acid content, a common trait among citrus fruits.
- Discussions about dinosaurs often revolve around their historical existence, based on fossil evidence and scientific research into prehistoric life.
