CATBRIDGE — SCIENCE STUDYING MATERIALS

The Solar System

  • • General overview: what the Solar System includes.
    • The Sun, planets, moons, asteroids, comets.
    • The concept of orbit.

 

The Sun

 

Mercury

Earth and the Moon

  • • Features of Earth: atmosphere, water, life.
    • The Moon as a satellite: phases of the Moon, tides.

 

Mars

  • • The Red Planet: climate, surface, exploration .
    • Possibility of life.

 

Jupiter

Saturn

  • • Famous rings.
    • Structure of the planet and its moons (e.g., Titan).

Minor Bodies of the Solar System

  • • Asteroids, meteors, meteorites.
    • The asteroid belt, the Kuiper belt.
    • Comets and their tails.

 

The Solar System and Beyond

  • • The concept of “dwarf planets” (Pluto and others).
    • Comparison of the Solar System with other star systems.
    • Exoplanets.

The Why does it rain?

  • • Rain happens because water undergoes evaporation, then condensation in clouds, and finally—under the force of gravity—it falls as precipitation.

Why does the wind blow?

  • • Wind is air moving from high to low pressure because the Sun heats Earth unevenly.

The process of Photosynthesis

  • • Photosynthesis is when plants use sunlight to turn carbon dioxide and water into glucose and release oxygen.
