Flight ✈️
This force pulls objects toward the Earth.
What is gravity?
This system in your body helps you breathe.
What is the respiratory system?
What we call the flow of electric charge.
What is current?
These are the three main states of matter.
What are solid, liquid, and gas?
The definition of conserving energy.
What is to use less energy or to use it wisely?
These are the four forces involved in flight.
What are lift, weight, thrust, and drag?
This organ pumps blood throughout your body.
What is the heart?
What is a conductor?
This state of matter has a definite shape and volume.
What is a solid?
One way to conserve energy at home.
(Answers may vary) Examples: What is turning off the lights when not in use, unplugging devices?
These parts of airplanes are essential in helping the airplane lift off the ground.
What are the wings?
This system includes your brain, spinal cord, and nerves.
What is the nervous system?
The name given to the path that electricity flows through.
What is a circuit?
This is what happens to particles when a solid melts.
What is they move faster and spread apart?
This type of energy is stored in food.
What is chemical energy?
The way in which the shape of a bird's wing helps it to fly.
What is the curved top and flat bottom create lift (air moves faster over the top)?
This system breaks down food so your body can use it for energy.
What is the digestive system?
This is what happens in a circuit if the switch is open.
What is the electricity stops flowing?
This is the name of the process when a gas turns into a liquid.
What is condensation?
Why it is important to use renewable energy sources.
What is because they don’t run out and are better for the environment?
The reason airplanes need to overcome drag in order to fly efficiently.
What is because drag slows the plane down, and overcoming it allows smoother, faster flight?
The way in which the circulatory and respiratory systems work together.
What is working together to deliver oxygen to the body and remove carbon dioxide?
This is what happens to the particles to allow electricity to flow.
What are the atoms share electrons and the electrons flow throughout the circuit?
The five signs that a chemical change has taken place.
What are: releasing a gas, the formation of a precipitate, absorbing or releasing heat and/or light, a colour change, and the production of an odour.
Explain how energy is conserved in a closed system.
What is energy is not lost or created, only transformed from one form to another?
