Steps of the scientific Method
Purpose/Question: What you're trying to "find out"
Research: Find out what other scientists have discovered
Hypothesis: A prediction as to what you think will happen
Experiment: Design & carry out experiment; use variables.
(Dependent Variables, Independent Variables, Control)
Analysis: Look over/review the data from your experiment
Conclusion: Was your hypothesis correct?
Pseudo Science (Definition and Examples)
Fake science - cannot be answered using the steps of the scientific method
Examples: Astrology, Paranormal investigations, Cultural Rituals
True Science (Definition and Examples)
Can be answered using the steps of the scientific method
Examples: Earth Space Science, Astronomy, Biology, Chemistry, Physics, Physical Science, Marine Science
The best explanation for a situation or event that is backed up by observations, evidence, and facts. It is the consensus of the scientific community.
Theories change because as new technological advances are created, new observations are made and new evidence is found.
A universally accepted conclusion that is made based on repeated scientific experimentation over many years.
Laws do not change.
A prediction as to what you think will happen (or what the "answer" is) to the question being tested
The variable that is changed by the scientist or experimenter to see how the dependent variable responds
The variable that changes based on the independent variable
The variables in an experiment that stay the same throughout and are the same in every trial.
Everything located outside the Earth, in space; stars, galaxies, and the sun
The thin layer of gases surrounding Earth (where the weather occurs)
All the ice on Earth
All the water in oceans, rivers, lakes, streams, and underground
Every living thing on Earth
The land surfaces and interior of Earth which include where volcanoes and earthquakes occur
Examples of Lab Safety
- Never work alone
- Partners can help you prevent an accident
- Always follow the directions in the lab
- Make sure to handle your materials carefully
- No "goofing off" when doing a lab
- When necessary wear protective equipment and clothing.
- Ask your teacher if you have ANY questions
- Keep your lab area clean
- Don't eat or drink while doing a lab
A push or pull that causes an object to move
The distance around a circle
The amount of space an object takes up. Measured using a graduated cylinder for irregular shapes or by multiplying length x width x height
The amount or number of something (How many are there?)
The amount of matter an object has. Measured using a digital scale or triple beam balance (Metric system base unit - grams)
The average kinetic energy of molecules in an object or system or simply put the hotness or coldness of a body or environment. Measured using a thermometer (Metric system base unit- Kelvin, or Celcius)
Also known as the SI (Standard International) system of measurement is accepted worldwide. We start with "base" units
The distance between two points (Metric system base unit - meters).
The closeness of a value to the real or true value
The agreement among a set of measurements made of the same quantity in the same way
Use shaded bars to represent data. The height of each bar represents a specific numeric value.
Shows the relationship between two variables.
Pie or Circle Graph
Compares percentages of data
Shows the relationship between two or more variables in a data set
Parts of an Atom
Protons, Neutrons, Electrons (can also include the nucleus and electron cloud)
Negatively charged particle found outside of the nucleus of an atom
Neutral particle found inside of the nucleus of an atom
Positively charged particle found inside of the nucleus of an atom
Came up with the first atomic theory:
1. All matter is made of atoms
2. All atoms in 1 type of element are the same
3. Atoms can't be created or destroyed
4. Atoms react with other atoms to cause chemical reactions
Atoms can combine to form compounds
Discovered electrons in atoms
Discovered that atoms had a nucleus
Published a model of the atomic structure
Discovered neutrons inside of an atom
Bonds that form when atoms gain or lose electrons
Bonds form when atoms share electrons
A force of attraction between two objects
A force that attract a positive charge towards a negative charge
Strong Nuclear Force
A force that help protons and neutrons to stay at the center of the atom
Weak Nuclear Force
A force that allows particles of matter to change from one form to another
A characteristic that can be described or observed. Examples include color, density, ductility, malleability, shape, mass, melting point, boiling point, phase/state, volume.
A property of matter that is observable only when one substance changes to another substance. Examples include flammability, Reaction to acids and bases, decomposition, corrode
States of Matter
Law of Conservation of Matter
When something goes through a physical or chemical change at the end of the change there is still the same amount of matter as you started with. (It might be different, but the total amount is still the same.)
Occurs when a material is in direct contact with another material with a different heat energy
Occurs when warm fluids rise and cool fluids sink
The transfer of energy through waves
Law of Conservation of Energy
States that any form of energy can be transformed to any other form of energy without a loss of net energy
Energy that is stored
Energy of motion
Parts of an Atom
Protons (+ charge)
Neutrons (neutral charge)
Electrons (- charge)
