Science
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.
Conclusion
An idea developed from reasoning and investigating. Conclusion. In science, a conclusion is a judgment based on data and experiments.
Control explained in an easy to understand way.
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.
Density explained in an easy to understand way.
Density
An object's mass per unit volume density. Density is how much stuff is packed into a given space.
Dependent variable explained in an easy to understand way.
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.
Element explained in an easy to understand way.
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.
Experiment explained in an easy to understand way.
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.
Hypothesis explained in an easy to understand way.
Hypothesis
A possible explanation or answer to a scientific question. Hypothesis. A hypothesis is an educated guess that scientists test through experiments and observations.
Independent variable explained in an easy to understand way.
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.
Mass explained in an easy to understand way.
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.
Matter explained in an easy to understand way.
Matter
Anything that has volume and mass. Matter. Matter is anything that takes up space and has weight.
Model explained in an easy to understand way.
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.
Observation explained in an easy to understand way.
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.
Scientific law explained in an easy to understand way.
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.
Scientific method explained in an easy to understand way.
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.
Technology explained in an easy to understand way.
Technology
The use of scientific observations to solve practical problems. Technology. Technology is using scientific knowledge to create tools and solutions for everyday life.
Theory explained in an easy to understand way.
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.
Weight explained in an easy to understand way.
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.
