The Scientific Method
This is the first step of the scientific method where you identify something you want to learn more about.
What is asking a question?
A change in which two substances become a new compound.
What is a chemical change?
This is the process plants use to make their own food using sunlight, carbon dioxide, and water.
What is photosynthesis?
This is the basic unit of structure and function in all living things.
What are cells?
This is the process by which organisms better adapted to their environment survive and reproduce.
What is natural selection?
This is a testable explanation based on observations and prior knowledge.
What is a hypothesis?
This is the smallest unit of an element that still retains its properties.
What is an atom?
This process releases energy from glucose using oxygen in cells.
What is cellular respiration?
This organelle controls the activities of the cell and contains DNA.
What is the nucleous?
This term refers to a trait that helps an organism survive and reproduce in its environment.
What is adaptation?
In an experiment, this is the variable that is purposely changed by the scientist.
What is the independent variable?
These are substances made of two or more elements chemically combined.
What are compounds?
The father of modern genetics.
Who is Gregor Mendel?
This structure surrounds the cell and controls what enters and leaves.
What is the membrane?
This scientist developed the theory of evolution by natural selection after observing organisms like finches.
Who is Charles Darwin?
This type of data is descriptive and involves qualities like color, texture, or smell.
What is qualitative data?
Found on the periodic table, these elements are found in group 1, are reactive with Halogens, and have one valance electron.
What are Alkali Metals?
Gregor Mendel discovered that traits are passed from parents to offspring through these units of heredity.
What are genes?
This organelle is found in plant cells and is where photosynthesis occurs.
What are chloroplasts?
This occurs when individuals with favorable traits survive and reproduce more successfully than others.
What is 'survival of the fittest'?
This is the group in an experiment that does not receive the independent variable and is used for comparison.
What is the control group?
What are Acids & Bases?
This term describes different forms of a gene, such as dominant or recessive traits.
What are alleles?
This is the rigid outer layer found in plant cells that provides support and protection.
What is the cell wall?
This is the gradual change in a species over time due to inherited traits.
What is evolution?
