What is Science?
An investigation in which all conditions are controlled is an
experiment
matter with a definite volume but no definite shape is a
liquid
forces that cause a change in motion are
unbalanced forces
True or False:
Camouflage is an adaptation that helps an organism survive and live in its environment
True
When the last of its kind dies, a species is
extinct
Together, a star and all the planets and other objects orbiting it form a
solar system
Information that scientists collect as they investigate the world is
evidence
matter without a definite volume or shape is a
gas
a push or pull that causes movement or change in an objects movement or shape is a
force
The different processes that an animal goes through as it grows and reproduces is called its
life cycle
The remains or traces of a plant or animal that lived long ago is a
fossil
a huge ball of very hot, glowing gasses in space that can produce its own heat and light is called a
star
a belief or judgement that is not supported by investigation is an
opinion
changes in which the form or shape of a substance changes but the chemical make up does not is called a
physical change
a force that opposes motion and acts between two objects that are touching is
friction
A characteristic that is passed from parents to offspring is an
inherited trait
An event that results in the dying off of many species is called a
mass extinction
a group of solar systems that are held together by gravity and classified by shape is called a
galaxy
the process of applying the engineering design process to living things is
bioengineering
changes in one or more substances that form new and different substances are called
chemical changes
the behavioral pattern or tendency of objects to resist a change in motion is
inertia
a behavior that needs to be taught is a
learned behavior
A fossil of an organism that lived many places during a short time span is called an
index fossil
a chunk of rock or iron that is less than 1000 km in diameter and orbits the sun is called an
asteroid
artificial legs are an example of
biotechnology
a mixture that has the same composition throughout is called a
solution
forces on an object that are equal in size and opposite in direction are
balanced forces
the part of a chromosome that contains information for specific inherited traits is a
Which life form was common during the Mesozoic Era?
Dinosaurs
When the moon is between the earth and the sun and blocks the sun's light, this is called a
solar eclipse
