What is Science?
This term describes the systematic study of the natural world through observation and experimentation.
What is science?
This is typically the first step of the scientific method, where a scientist makes an observation and asks a question about it.
What is observing and asking a question?
A scientific law only describes WHAT happens in nature; this type of scientific idea instead explains WHY or HOW it happens.
What is a (scientific) theory?
This SI base unit, symbol “m,” measures length or distance.
What is the meter?
In science, this term refers to a representation of an idea, object, or process that helps us understand something we can't directly observe.
What is a model?
Science is often divided into three main branches: earth science, life science, and this branch, which studies matter and energy.
What is physical science?
After asking a question, a scientist writes this: a testable, educated prediction that can be checked through experimentation.
What is a hypothesis?
This term describes a pattern in nature that has been observed repeatedly and consistently, often written as a short statement or equation.
What is a scientific law?
This SI base unit, symbol “kg,” measures mass.
What is the kilogram?
This type of model uses physical object, like a globe or a skeleton replica, to represent something real.
What is a physical model?
A scientific claim must be __________. Hint: capable of being tested and potentially proven wrong by evidence.
What is testable?
After forming a hypothesis, this step involves designing and carrying out a test to collect data.
What is conducting an experiment (testing the hypothesis)?
A scientific theory is not just a guess. It is this instead, built from a lot of testing and evidence.
What is a well-supported explanation?
This SI base unit, symbol “s,” measures time.
What is the second?
This type of model uses numbers and equations to represent and predict how a system behaves, such as predicting weather or population growth.
What is a mathematical model?
Science relies on this thing, gathered through the senses or instruments, rather than on opinion or authority alone.
What is evidence (observation/data)?
After experimenting, scientists do this with their data: looking for patterns.
What is analyzing the data?
This is a well-known scientific law that describes how all matter in the universe attracts all other matter and keeps us down on earth.
What is the Law of Gravity?
This SI base unit, symbol “K,” measures temperature on an absolute scale that starts at absolute zero.
What is the Kelvin?
Models are especially useful for representing things that are too big, too small, too slow, too fast, or this, such as an atom or the solar system.
What is "too dangerous or impossible to observe directly"?
This is the main goal of science: not to prove ideas with absolute certainty, but to build and continually test this kind of explanation.
What is a reliable, evidence-based explanation of the natural world?
After analyzing, scientists do this with their data: checking whether it supports the hypothesis.
What is drawing a conclusion?
This is a well-known scientific theory that explains how species change came to be.
What is the Theory of Evolution?
This SI unit measures measures electric current.
What is the ampere?
Because models are simplified representations, they are considered _____________.
What is limited/incomplete?
