a fluid exerts on an object that is placed in it; the
tendency of an object to float in a fluid.
Buoyant force: The pressure
pushing up on an object in water or air.
Classify: To group things
together because they share one or more properties.
Conclusion: A decision that is
based on observation or on a study of data.
Constant: A condition that is
based on observation or on a study of data.
Construct: To make by putting
together parts.
Data: Information, such as that
gathered during an experiment.
Density: The amount, or mass,
of a specific volume of a substance.
Design: A sketch or model that
shows how something is or is to be built.
Dissolve: To make or become
liquid.
Distribute: To spread out.
Equal: The same in amount,
size, value, quality, or other characteristics.
Evidence: Something that offers
proof.
Exert: To make use of; to
apply.
Experiment: A procedure that is
carried out to investigate a scientific question.
Float: To rest on or at the
surface of, or be suspended in, a liquid.
Gram: A unit of mass in the
metric system.
Gravity: The attraction of the
earth or other bodies for any object at or near their
surface. The force of gravity depends on the masses of the
objects and how far apart they are.
Greater: Larger in size,
number, or amount.
Hypothesis: A prediction about
how something works or how two variables are related.
Invent: To think up or create
something for the first time.
Liquid: A substance that has no
shape but does have volume.
Mass: The amount of matter that
an object contains. Mass is expressed in grams or ounces.
Mean: The number that falls an
equal distance between two extremes; the average. To
determine the mean, add the numbers in a set and divide the
total by the number of items. For example, the mean of 1,
3, 5, 7, and 9 is 5 (25 divided by 5).
Median: The middle number in a
set of numbers. If the set of numbers is 22, 33, and 44, the
median is 33.
Mode: The number that occurs
most often in a set of numbers in the series 2, 4, 6, 6, 10,
the mode is 6.
Pattern: A repeating
arrangement of shapes, colors, numbers, or other things.
Procedure: A set of steps that
explains how to do something.
Result: Outcome of an
experiment.
Saturate: To soak or fill
something until it cannot absorb or dissolve any additional
material.
Saturated solution: A solution
that cannot dissolve any additional material.
Sink: To move downward; to go
to the bottom of.
Solid: A substance that takes
up space and has its own shape.
Solution: A liquid in which
something has been dissolved.
Volume: The amount of space
that a substance takes up.
Weigh: To measure how heavy
something is.
Weight: A measurement of how
heavy something is.
