Procedure you carry out under controlled conditions to test a hypothesis.
What is an experiment?
100
The amount of matter in an object compared to the space it takes up
What is density?
100
The smallest possible particle of a substance
What is an atom?
100
Energy of motion (riding a bike, airplane flying)
What is kinetic energy?
100
A push or a pull that causes change in motion (speeds it up, slows or changes the direction)
What is force?
200
Using inquiry skills to gather data and answer questions
What is an investigation?
200
Has no definite volume but no definite shape, takes the shape of its container and can be poured from one container to another
What is liquid?
200
A physical change that occurs when matter changes from one state to another (liquid to solid-water to ice)
What is change of state?
200
The energy an object has because of its position or condition (higher a book is the farther it can fall)
What is potential energy?
200
A force that works against motion ( slows or stops things-rough surface)
What is friciton?
300
A series of 5 steps involved in a true experiment
What is the scientific method?
300
The amount of matter something contains (heavy object has more mass than a light object)
What is mass?
300
A change in a substance produced by chemical means that results in a different substance (irom rusting, egg changing to sunny side up, bread dough rising and browning into bread)
What is chemical change?
300
The ability to cause change in matter ( arm muscle provides energy for a ball to move, car engine provides energy to move car)
What is energy?
300
The force of attraction between objects (ball drops and is pulled to the floor, causes objects to speed up as they fall, earth's gravity attracts objects near it's surface and pulls them toward its center)
What is gravity?
400
Observe and ask question
form a hypothesis
plan an experiment
conduct an experiment
draw conclusions
What is the steps to the scientific method?
400
Anything that has mass and takes up space (you, book, clothes)
What is matter?
400
A substance made of 2 or more different elements that have chemically combined (water made up of hydrogen and oxygen atoms)
What is a compound?
400
Movement of energy from one place or object to another (jump on a trampoline which propels you into the air)
What is energy transfer?
400
The pull of all objects in the universe on one another
What is gravitation?
500
Safety equipment needed for a science experiment
What is safety glasses, lab coat, and gloves?
500
The amount of space that matter takes up
What is volume?
500
A substance made up of just one kind of atom (oxygen, iron, silver)
What is an element?
500
Using less of something to make the supply last longer (less water to make water supply last, less paper to save trees)
What is conservation?
500
The balance point of a lever, supports the arm but doesn't move
