Scientific Inquiry
This is the process of investigating and exploring the natural world.
What is scientific inquiry?
This is information collected through observation or experimentation.
What is data?
This is the act of gathering information through your senses.
What is an observation?
This is the basic unit of matter.
What is an atom?
Anything that has mass and takes up space.
What is matter?
This is a testable prediction about the relationship between variables.
What is a hypothesis?
This type of data uses descriptions or characteristics that cannot easily be measured with numbers.
What is qualitative data?
You see dark clouds and conclude that it will probably rain. This conclusion based onevidence and reasoning is called what?
What is an inference?
This is a particle smaller than an atom.
What is a subatomic particle?
A substance made up of two or more different elements chemically combined.
What is a compound?
In an experiment, this is the factor that a scientist deliberately changes or manipulates.
What is the independent variable?
This type of data uses numbers and can be measured.
What is quantitative data?
This is a well-supported explanation for a natural phenomenon.
What is a theory?
Name the three main subatomic particles found in an atom.
Electron, proton, and neutron
This is the force that holds atoms together in a compound.
What is a chemical bond?
A scientist changes the amount of water given to plants and measures how muchthey grow. What is the dependent variable?
What is plant growth?
A student records the following test scores: 70, 80, 80, 90, and 100. What is themode?
What is 80?
This scientific term describes a rule that describes a pattern in nature.
What is a law?
This negatively charged particle is found outside the nucleus of an atom.
What is an electron?
In the formula H₂O, the small number 2 written below and to the right of H is called what?
What is a subscript?
A scientist gives fertilizer to one group of plants but not another. The group thatreceives the fertilizer is called what?
What is the experimental group?
A scientist records these temperatures: 12°C, 15°C, 15°C, 18°C, and 25°C. What are the median and range?
Median = 15°C; Range = 13°C
A scientist notices that as the amount of sunlight increases, plant growth also increases. This relationship between two variables is called what. Does thisrelationship automatically prove that sunlight caused the growth?
What is correlation? No, correlation does not automatically provecausation
An atom's nucleus contains two types of particles. One has a positive charge and the other has no charge. What are they?
Proton and neutron
In a chemical reaction, the substances that participate in the reaction are called what, and the substances formed by the reaction are called what?
What are reactants and products?
