Earth and Space
This planet is the third planet from the Sun and the only known planet to support life.
Earth
This organ pumps blood around the body.
Heart
The basic building blocks of all living things are called these.
Cells
These tiny air sacs in the lungs are where gas exchange happens.
Alveoli
Matter exists in these three common states. Name them.
Solid, liquid, gas.
This galaxy contains our Solar System.
Milky Way galaxy.
These blood cells contain haemoglobin and carry oxygen around the body.
Red blood cells.
This part of the cell controls what enters and leaves the cell.
Cell Membrane
This tube carries air from the nose and mouth to the lungs.
Trachea
This change of state happens when a liquid turns into a gas.
Boiling
This theory says the universe began from a tiny, hot singularity about 14 billion years ago.
The Big Bang Theory
This liquid part of blood transports food, waste and heat around the body.
Plasma
This structure is the control centre of the cell and contains genes.
Nucleus
This muscle under the lungs helps air move in and out during breathing.

Physical change
These celestial bodies are often called “dirty snowballs” because they are made of ice, rock and dust.
Comets.
These blood components help blood clot and stop bleeding.
Platelets.
This inherited disorder causes sticky mucus to build up in the lungs.

During this type of change, reactants form new products.
Chemical change
According to Hubble’s Law, the farther away a galaxy is, the ______ it moves away from us.
Faster.
The wall that separates the left and right sides of the heart is called this.
Septum
These tiny structures in plant cells contain chlorophyll and allow photosynthesis to occur.
Chloroplasts
In aerobic respiration, glucose reacts with this gas to release energy.
Oxygen.
This scientific law states that mass cannot be created or destroyed during a chemical reaction.
Law of Conservation of Mass.
