Periodic Motion And Waves
100
The systematic study of the universe to produce observations, inferences, and models.
What is Science?
100
Anything that occupies space and has mass.
What is matter?
100
Scientists had observed that opposite electrical charges attract each other, while same charges repel each other.
What is the law of electrostatic charges?
100
A law that states the properties of the elements vary in a periodic way with their atomic numbers.
What is the periodic law?
100
Often the wave changes direction due to the change in medium. Occurs when the wave moves at different speeds in different media.
What is refraction?
200
Directs us to fill the earth and have dominion over it.
What is the creation mandate?
200
States that all physical matter exists in the form of particles (atoms or molecules) in constant motion.
What is the particle model of matter?
200
This model suggested negatively charged electrons embedded in a positive substance.
What is the plum pudding model?
200
This is a table of the chemical elements arranged in a way that displays their periodic properties in relationship to their atomic numbers.
What is the periodic table?
200
A mathematical equation that describes how the wave changes direction as itmoves into a new medium.
What is Snell's law?
300
A system of moral values or a theory of proper conduct.
What are ethics?
300
The building block of all matter. Consists of protons, electrons, and (usually) neutrons.
What is an atom?
300
The atom was made up of a dense, positively charged central nucleus surrounded by negatively charged electrons.
What is the nuclear model?
300
This is a set of elements in the same column on the periodic table.
What is a family or group?
300
The bending of waves around an obstacle or through an opening.
What is diffraction?
400
A workable explanation or description of a phenomenon.
What is a model?
400
***Daily double***
Brown hypothesized that particles of the fluid were colliding with the parts from the spores, causing their random motion.
What is Brownian motion?
400
A new branch of physics was born, one that explored the behavior of matter and energy at the atomic subatomic levels.
What is quantum mechanics?
400
The electrons in the outermost energy level of a neutral atom.
What are valence electrons?
400
An element, which separates polychromatic light into its constituent wavelengths.
What is diffraction grating?
500
A model that explains a related set of phenomena.
What is a theory?
500
A distinct group of two or more atoms covalently bonded together.
What is a molecule?
500
Spherical regions located at fixed distances from the nucleus.
What are energy levels?
500
***Daily double***
They are dull and brittle solids.
What is not a general property of metals?
500
Combining of waves where they overlap.
What is interference?
