Nature of Science
a prediction or possible explanation for a question that needs to be investigated
What is a Hypothesis?
A rigid layer of the Earth's surface made up of the crust and upper mantle.
What is lithosphere
The small particle that is the fundamental basis of all matter.
What is an atom?
The basic structural and functional unit of all living organisms.
What is a cell?
Any substance that has mass and occupies space, meaning it has volume.
What is a matter?
The group in a study that is used to compare the results of the other group; does not receive the independent variable.
What is control group?
The process by which plants release water vapor through the pores in their leaves
What is transpiration?
A change of matter from one form to another without a change in chemical properties
What is a physical change?
A system that groups organisms based on shared characteristics and evolutionary relationships. It helps scientists understand the diversity of life and how organisms are related to each other.
What is Taxonomy( classification of living things)
A measure of apparent brightness as viewed by an observer on Earth.
What is apparent magnitude?
condition or factor that is manipulated by a scientist during an experiment.
What is independent variable?
The theory that the lithosphere is composed of tectonic plates that move from convection currents in the mantle.
What is the theory of plate tectonics?
The law that states that mass cannot be created or destroyed in ordinary chemical and physical changes.
What is the low of conservation of mass?
The process by which cells break down food molecules, like glucose, in the presence of oxygen to release energy in the form of ATP.
What is cellular respiration?
The falling and rising of sea levels which are formed by the interaction of the gravity of the Sun and Moon
What are tides?
when a scientist (student) conducts the same experiment as another scientist in order to verify their results, when the same results are collected, regardless of who is conducting the experiment
What is replication?
Periods of the year with distinct weather patterns and daylight hours, caused by the Earth's tilt on its axis as it orbits the sun.
What is seasons?
The bending of light, sound, or other waves as they pass from one medium to another
What is refraction?
Environmental conditions or variables that restrict the growth, abundance, or distribution of a population in an ecosystem.
What are limiting factors?
section of DNA that codes for an inherited trait.
What is a gene?
a well tested explanation for a wide variety of observations and experimental results.
What is a theory
A high-altitude wind current that flows in a wavy path from west to east, influencing weather patterns.
What is Jet stream?
A combination of two or more substances where each substance retains its individual properties, and the substances can be separated by physical means.
What is a mixture?
A key mechanism of evolution, where individuals with traits better suited to their environment are more likely to survive and reproduce, passing on those advantageous traits
What is Natural selection?
A substance formed when two or more elements are chemically bonded together
What is a compound?
