What is false?
A hypothesis must be...?
What is testable and falsifiable?
In an If/then statement what are the experiment variable being discussed?
"If...(____ variable), then... (_____ variable)."
What is independent variable and dependent variable?
What is the weight of protons, neutrons, and electrons?
What is 1amu, 1amu, and negligible?
To make an atom with a +1 charge what do you do?
What is remove a electron?
The difference between quantitative and qualitative data is?
What is quantitative is numerical data and qualitative is descriptions?
From least to greatest, what is the hierarchy of biological organization?
What is organisms, population, communities, ecosystems, and biosphere?
A scientist was observing what honeybees in an open meadow visited most frequently, she recorded that honeybees visited sour smelling flowers over sweet smelling flowers. Based on her results she concluded honeybees must prefer sour odors.
Is this a controlled experiment?
What is no?
An atom contains 18 neutrons and 17 protons. What is its atomic and mass number?
What is an atomic number of 17 and a mass number of 35?
Given only the atomic number of an element, what do you know?
What is # of protons, neutrons, and electrons?
The y-axis on a graph is the what of an experiment?
What is dependent variable?
The molecular geometry of water is?
What is bent?
Dr. Elena Martinez of Pacific Coast University studied the navigational abilities of homing pigeons under different light conditions. Pigeons were released in an open field and exposed to natural daylight or to artificial light that altered the polarization of the sky. The researchers measured the direction in which the pigeons flew. Results show that pigeons flew in one direction when exposed to natural daylight, but in a different direction when exposed to the altered artificial light. What conclusion can be drawn from this?
What is the pigeons’ ability to navigate is influenced by the polarization of light, indicating that they use visual cues from sunlight for orientation?
What is the difference between H and its isotope H-2?
What is one more neutron?
To complete its octet, an atom with an atomic number of 11 would make a bond with what type of atom?
What is an atom with a +1 charge?
Atomic number 11 = 11 electrons and 1 valance electrons. Bonding with a +1 charged atom to lose its valance electron.
What is a scientific law?
What is tells you what happens and is based on repeated observations/experiments?
Does NOT tell you the why
A basic solution has a greater ___ concentration vs ___ concentration
What is hydroxide OH- vs hydrogen H+?
For an experiment to be credible, results have to be...?
What is repeated and peer reviewed?
Fill in the blank
Protons affect an atoms...
Neutrons affect an atoms...&...
Electrons affect an atoms...
What is element, weight/isotope, and charge?
The unequal sharing of elections is what type of bond?
What is polar covalent bond?
Equal sharing = non-polar, unequal sharing = polar. Polarity is based on unequal sharing of electrons because it creates a dipole moment where on atom is partially - and the other partially + which makes a polar molecule.
What is a theory?
What is broader than a hypothesis but testable, and supported by a large body of evidence?
What are the names of your LAs?
What is Andri'anna and Leonardo?
