Nuclear Age
This is the process by which an unstable atomic nucleus loses energy by emitting radiation.
Radioactive Decay
The Atomic Symbol for Hydrogen
This term refers to the living components of an ecosystem, including plants, animals, and microorganisms
Biotic Factors
This term refers to how consistently an experiment can produce the same results under the same conditions
Reliability
This river is the longest in the world, flowing through Egypt.
The Nile River
In this type of nuclear reaction, two light nuclei combine to form a heavier nucleus, releasing energy. It is the process that powers the sun
Nuclear Fusion
Which subatomic particle has a positive charge?
Proton
In a food web, this type of organism eats both plants and animals.
Omnivore
This step involves forming a possible explanation based on prior knowledge or research, which can be tested through experiments
Hypothesis
This famous artist painted the Mona Lisa.
Leonardo da Vinci
The time it takes for half of a sample of a radioactive substance to decay is called its:
Half-life
This is the term for two or more atoms bonded together.
Molecule
These organisms break down dead plants and animals, recycling nutrients back into the ecosystem.
Decomposers
These variables are kept constant across all trials of an experiment to ensure the results are reliable and valid.
Controlled Variables
This planet is known as the "Red Planet" due to its reddish appearance caused by iron oxide.
Mars
This event in 1945 marked the first use of nuclear weapons in warfare, when the U.S. dropped an atomic bomb on this Japanese city
Hiroshima
How many electrons can be found in the second energy level of an atom?
8
The process by which carbon is exchanged between the atmosphere, oceans, and living organisms is called:
The Carbon Cycle
This is the factor that is deliberately changed in an experiment to test its effect on the dependent variable.
Independent Variable
This country is made up of over 7,000 islands and is located in Southeast Asia.
The Philippines
This type of radiation is the most penetrating and requires thick layers of concrete or lead for shielding. It is produced during nuclear fission and is often a concern in nuclear reactors.
Gamma Radiation
The number of protons in an atom determines its atomic number and its identity. However, atoms of the same element can have different numbers of neutrons. These atoms are known as
Isotopes
This ecological interaction benefits one species and harms the other, often leading to one species living inside or on the other, such as lice on mammals.
Parasitism
When designing an experiment that involves human participants, researchers must ensure that participants provide this type of agreement, acknowledging that they understand the experiment and any risks involved.
Informed Consent
This British rock band, formed in the 1960s, is known for iconic albums such as "Sgt. Pepper's Lonely Hearts Club Band" and "Abbey Road," and for songs like "Hey Jude" and "Let It Be."
