Science and Inquiry
A systematic way of learning about the world
What is Science?
The measure of the quantity (or amount) of material in a substance
What is mass?
State of matter with a definite shape and volume
What is a solid?
Smallest unit of matter
What is an atom?
The starting material or substance in a chemical reaction
What are reactants?
Observation, Research, Hypothesis, Experiment, Data Collection, Conclusion
What are the steps of the scientific method?
Grams
What is the unit used to measure mass?
Type of matter that is uniform and must be composed of only one element or compound
What is a pure substance?
Protons and neutrons condensed together in the center of an atom
What is the nucleus?
Type of reaction where smaller reactants are combined to form a larger molecule.
What is synthesis? (other names could be acceptable)
A tool to answer questions and solve problems, often used to conduct research and inquiry.
What is the scientific method?
The measure of how fast the particles within a substance are moving
What is temperature?
An state of matter, which is an ionized gas with free electrons.
What is plasma?
Different forms of an element with varying neutron numbers
What are isotopes?
Type of reaction where energy is needed to activate the reaction.
A type of observation based on a measurable value or number.
What is a quantitative observation?
Word used to describe when data values are close to each other, but are not necessarily close to the desired value.
What is precision?
Sublimation
What is the change in state from a solid to a gas?
What are alkali metals? (or What is group 1)
Process completed with a chemical reaction to ensure the law of conservation of mass is maintained
What is balancing chemical equations?
Describes a common occurrence that is proven to happen repeatedly
What is a scientific law?
Notation used to describe very large or very small values in the format: base number * 10^exponent
What is scientific notation?
While energy can change from one form to another, it can be neither created nor destroyed.
What is the law of conservation of energy? (or what is the first law of thermodynamics)
Outermost shell of electrons, atoms react in order to make this shell complete.
What are valence electrons?
Substances that release hydrogen ions (H+) when dissolved in water
What is an acid?
