Intro to Chemistry

Science

The study of the properties of matter and how matter changes

Chemistry

The study of the properties of matter and how matter changes. Chemistry. Chemistry is the science that explores what things are made of and how they interact and change.

An idea developed from reasoning and investigating

Conclusion

An idea developed from reasoning and investigating. Conclusion. In science, a conclusion is a judgment based on data and experiments.

The standard used for comparison of test results in an experiment

Control

The standard used for comparison of test results in an experiment. Control. In science, a control is a part of an experiment that does not change and is used to compare with the parts that do change.

An object’s mass per unit volume

Density

An object's mass per unit volume density. Density is how much stuff is packed into a given space.

The factor measured at the end of an experiment

Dependent variable

The factor measured at the end of an experiment. Dependent variable. In Science, a dependent variable is what you measure in an experiment to see how it changes in response to other variables.

A substance made of one type of atom that cannot be broken down chemically

Element

A substance made of one type of atom that cannot be broken down chemically. Element. An element is a basic substance that everything is made of and is found on the periodic table.

Testing a hypothesis by collecting data in controlled conditions

Experiment

Testing a hypothesis by collecting data in controlled conditions. Experiment. In Science, an experiment is a method where scientists test ideas by making observations and collecting data.

A possible explanation or answer to a scientific question

Hypothesis

A possible explanation or answer to a scientific question. Hypothesis. A hypothesis is an educated guess that scientists test through experiments and observations.

The variable which is manipulated by the researcher

Independent variable

The variable which is manipulated by the researcher. Independent variable. It is the factor in an experiment that is purposely changed to observe its effect.

The amount of matter in an object

Mass

The amount of matter in an object. Mass. In simple terms, mass is how much "stuff" is inside an object, and it affects how much force is needed to move it.

Anything that has volume and mass

Matter

Anything that has volume and mass. Matter. Matter is anything that takes up space and has weight.

A representation of an object or system

Model

A representation of an object or system. Model. In Science, a model is a simplified version of something complex used to understand, explain, or predict how it works.

The process of using your senses to gather information

Observation

The process of using your senses to gather information. Observation. In Science, observation is about carefully watching and noting what happens in experiments or nature to learn and understand.

A rule that describes what happens in nature

Scientific law

A rule that describes what happens in nature scientific law. Scientific law is a statement based on repeated experimental observations that describes an aspect of the world.

Includes gathering info, testing a hypothesis, analyzing data and drawing conclusions

Scientific method

Includes gathering info, testing a hypothesis, analyzing data, and drawing conclusions. Scientific method. The scientific method is a systematic process used by scientists to explore and understand the natural world.

The use of scientific observations to solve practical problems

Technology

The use of scientific observations to solve practical problems. Technology. Technology is using scientific knowledge to create tools and solutions for everyday life.

Explanation of observations supported by evidence

Theory

Explanation of observations supported by evidence. Theory. In Science, a theory is a well-tested idea that explains how or why something happens based on evidence.

Measure of the force of gravity on an object

Weight

Measure of the force of gravity on an object. Weight. In simple terms, weight is how much gravity pulls on you or an object.
