Scientific Method
The first step of the scientific method where you notice something curious using your 5 senses or lab measuring tools.
What is Observe?
Formulate a hypothesis for how ramp height affects a toy car's rolling distance.
What is "If the height of the ramp increases, then the toy car will roll farther"?
The variable in an experiment that you intentionally change or manipulate.
What is the Independent Variable?
Science is a system of knowledge and the ________ you use to find that knowledge.
What are methods?
The two main branches of Natural Science besides Physical Science.
What are Earth & Space Science and Life Science?
his final step of the scientific method determines whether your data supports or refutes your original hypothesis.
What is Conclude?
Formulate a hypothesis predicting what happens when dropping a bowling ball and feathers in the air.
What is "If both are dropped in air, then the bowling ball will fall faster due to air resistance"?
The variable that you measure in response to changes made during an experiment (like distance a car rolls).
What is the Dependent Variable?
The goal of __________ is to use knowledge to solve practical problems. Also known as applying knowledge.
What is technology?
The estimated age of the universe according to the Big Ideas of physical science
What is 13.7 billion years old (13,700,000,000 years)?
This type of scientific statement describes WHAT happens in nature, such as the Law of Conservation of Energy.
What is a Scientific Law?
Formulate a hypothesis predicting what happens when dropping a bowling ball and feathers in a vacuum.
What is "If both are dropped in a vacuum, then they will fall at the exact same rate"?
Name two variables that must remain constant when testing how ramp height affects a toy car.
What are the same toy car and the same floor surface (or release point without pushing)?
The two main branches that make up Physical Science.
What are Chemistry and Physics?
The four big ideas of physical science.
What are Space & Time, Matter & Change, Forces & Motion, and Energy?
This type of scientific statement explains WHY things happen in nature.
What is a Scientific Theory?
Formulate a hypothesis testing how changing floor surfaces affects how far a toy car rolls.
What is "If the floor surface is made smoother, then the toy car will roll a greater distance"?
A 3D object you can see and touch, like a globe or a DNA double helix model.
What is a Physical Model?
The study of the composition, structure, properties, and reactions of matter.
What is Chemistry?
The reason why a bowling ball and a feather fall at the exact same rate inside a vacuum.
What is because there is no air resistance?
The exact percentage chance that a scientific theory has of graduating into a scientific law.
What is 0%?
Formulate a hypothesis testing how adding weight to a toy car affects its motion down a ramp.
What is "If weight is added to the toy car, then it will roll down the ramp at a faster speed"?
Equations like Newton's 2nd Law ($F = ma$) fall under this category of scientific models.
What are Conceptual & Mathematical Models?
The study of matter and energy and the interactions between the two through forces and motion.
What is Physics?
A major limitation of using models to represent systems like our solar system
What is that no model is 100% perfect (they simplify reality and cannot show true scale size and distance simultaneously on paper)?
