Nature of Science
What is a "Controlled Experiment"?
What is An experiment in which only one variable is manipulated at a time?
Heat from the core and the mantle intself causes convection currents in the mantle.
What is Thermal Energy?
The internal energy of an object due to the kinetic energy of its atoms and/or molecules.
What is the shape of DNA?
A double helix.
What is a factor that changed to test a hypothesis?
The soft layer of the mantle on which the lithosphere floats.
What is Nuclear Energy?
Energy released during nuclear fission or fusion
What is refraction?
When a light or sound wave bounces off in a different direction.
What is Asexual reproduction?
Generates offspring that are genetically identical to a single parent.
Explain the purpose of multiple trials
When you do more trials you can draw better conclusions.
How did Scientists determine the age of the Earth?
By using radiometric dating of rocks from Earth and space.
What is Electromagnetic Energy?
A form of energy that is reflected or emitted from objects in the form of electrical.
What is frequency?
The fact of being frequent or happening often.
What does DNA stand for?
Deoxyribonucleic acid
What is replication and how can it impact scientific progress?
What is the Lithosphere
A rigid layer made up of the uppermost part of the mantle and the crust.
Compare and contrast Kinetic and Potential Energy
Kinetic energy is the energy which an object contains because of particular motion. Potential energy is the stored energy.
What is Amplitude?
The maximum extent of a vibration or oscillation?
What factors can limit growth of population?
The fossil record, genetics, and examples of local adaptions.
A theory is a well tested explanation.
A law is a statement.
What is radioactive dating?
Determine the absolute ages of rocks
What happens when enough heat is added or removed from a system?
When a system is hot particles move faster. When it is cool particles move slower.
What is Wavelength?
The distance between the crests of a wave.
What evidence supports the Theory of Evolution by Natural Selection?
The fossil record shows a progressive timeline of how organisms adapt to survive in response to environmental stresses.
