Study Notes
Understanding Light
- Light is a form of energy that allows us to see objects
- Light travels in straight lines and can bounce off mirrors and other shiny surfaces
- The bouncing back of light is called reflection
Reflection of Light
- When light hits a mirror or a shiny surface, it bounces back
- The angle of incidence (incoming light) is equal to the angle of reflection (bounced light)
- Mirrors can be used to reflect light and make objects appear larger or smaller
The Solar System
- Our solar system consists of eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune
- The sun is at the center of our solar system and the planets orbit around it
- The planets differ in size, temperature, and composition
Day and Night
- Day occurs when the part of the Earth facing the sun is lit up
- Night occurs when the part of the Earth facing away from the sun is in darkness
- The rotation of the Earth on its axis causes day and night to alternate every 24 hours
