The variable that gets changed in an experiment.

The amount of matter in an object.

A push or pull on an object that can either be contact or non-contact.

All allow small solid items or liquid to go through while larger, solid items stay inside.

The change in appearance of a substance, but it doesn't change into a new substance. This includes change of state.

A process in which one or more substances has changed into one or more new substances with different chemical properties.

Removes solid particles from liquid when a sieve won't work.

The amount of space an object takes up or the amount of something a container can hold.

A force that moves an object away.

Sharing information based on observations or collected data in spoken or written form including drawings, graphs, and charts.

The variable that gets measured in an experiment.

A collection of facts, figures, or information gathered from observations and readings that can be analyzed to learn about something.

Any variable in an experiment that needs to stay the same.

Anything that has mass and takes up space.

A force that moves an object towards another object.

Used to separate small solids from larger solids by hand.

A chemical change in which a reddish-brown coating forms on metal that has been exposed to air and water.

Using heat to transform ingredients into new substances by baking, broiling, and other methods.

Used to separate magnetic from non-magnetic objects.

Matter exists in several different forms: solid, liquid, and gas.

When more than one force is acting on an object and there is no movement.

A way of finding answers to questions by carefully exploring and researching a subject.

The type of results obtained from doing repeated trials.

The number of times an experiment is conducted (usually 5 or more).

Matter that has a definite shape and volume.

When two or more forces are acting on an object and movement occurs.

A force that opposes motion.

Matter that takes the shape of its container and has a definite volume and mass.

Matter that has a changeable volume and shape with freely moving particles.

This tool is used to evaporate liquids from solids.

This method is used to separate objects that sink from those that float.

A chemical reaction that consumes fuel and gives off gas, light, or heat.

The breakdown of substances into new substances over time; to rot.

When you use clues from what you observe and what you already know to make an educated guess about something you can't directly see or know.

A special type of investigation where there is a testable question and variables.

A personal view or belief about something that can't be proven with evidence.

A type of question that can be answered by setting up an experiment and collecting data after repeated trials.

In an experiment this is the group that gets treated in a typical way so that the results can be compared to a group that was treated differently.

Properties that can be observed or measured including color, texture, mass, volume, shape state, etc.

The force that pulls everything to the center of Earth.

The unit of measure used to measure forces.
