Study Notes
Safety Equipment
- Seatbelts are safety equipment in cars.
Breathing
- Exhaled air contains oxygen.
Gravity
- Gravity pulls objects downward.
- Gravity is the force pulling objects towards the Earth.
Sound
- Sound pitch can be determined by smell.
Light
- The moon is a light source, reflecting sunlight.
Force and Motion
- An object won't move unless a force acts on it.
- Whales communicate using songs.
Digestion
- Digestion begins in the stomach with saliva.
Measurement
- Kilograms are a unit of speed.
Animal Adaptations
- Bats use their sense of smell for safety.
- The brain processes information.
Energy Change
- Energy can change from one form to another.
- Gravity is not an upward pulling force, it is an downward pulling force.
Communication
- Speaking and writing are ways to communicate.
Force
- Hitting a ball needs a force to move it.
- The bus traveling 60 kilometers per hour is equal to 60 m/s.
Energy Conversion
- Electrical energy turns into kinetic energy in an electric fan.
- Fennec foxes have short ears.
Energy and Work
- Potential energy is the energy of a moving body.
- Light travels in straight lines.
- Eating provides energy.
Body Systems
- The respiratory system brings air to the body.
- Speed is measured in kilograms (kilograms are the unit for mass, not speed).
Forces and Objects
- Objects fall due to friction force, not gravity pushing them down.
Transparence
- Wood allows light to travel.
Animal Adaptations
- Some animals have good night vision.
Science Concepts
- Exhaled air contains carbon dioxide.
- Thick white fur is an adaptation in polar bears.
- Potential energy decreases as elevation increases.
Forces and Motion
- The force of attraction to Earth is a pulling force, not a pushing force.
- Unbalanced forces change object position.
- Distance is measured in kilometers.
Animal Sensory Abilities
- Dolphins have excellent sight.
- Airbags absorb impact energy during collisions.
- Cats have good night vision.
Science Concepts
- The direction of force matters (pulling and pushing).
- Spines are adaptations to prevent animals from eating plants.
- Cat's eyes appear like lighted lamps at night.
