Scientific Method & Lab Safety
Which step must come before collecting data in the scientific method? *
Communicate findings
Drawing Conclusions
Forming a hypothesis
Forming a hypothesis
This term describes the rate at which an object changes its position.
Answer: What is speed?
Newton's First Law is also known by this name, describing an object's resistance to changes in motion.
Answer: What is the Law of Inertia?
This is the ability to do work or cause change.
Answer: What is energy?
This is the first step in the scientific method, where you define the problem you want to investigate.
Answer: What is ask a question?
Which of the following is true*
A scientific question is not based on observations
A researcher should conduct initial research before forming a hypothesis
A laboratory is the only place to test a hypothesis
A researcher should conduct initial research before forming a hypothesis
This is the formula used to calculate speed.
Answer: What is speed equals distance divided by time (speed = distance ÷ time)?
According to Newton's Second Law, the acceleration of an object depends on these two factors.
Answer: What are force and mass?
Energy that an object has because of its motion is called this.
Answer: What is kinetic energy?
The standard unit of mass in the metric system is this.
Answer: What is the gram (or kilogram)?
Scientific Hypothesis must be testable: this means*
The statement can be easily proven
Hypothesis have to be things that are true
A procedure can be designed determine if the hypothesis could be valid
A procedure can be designed determine if the hypothesis could be valid
This term describes speed in a specific direction.
Answer: What is velocity?
Newton's Third Law states that for every action, there is this.
Answer: What is an equal and opposite reaction?
This type of energy is stored due to an object’s position or condition.
Answer: What is potential energy?
This type of energy is stored in the bonds of atoms and molecules.
Answer: What is chemical energy?
This essential piece of lab safety equipment should be worn at all times to protect your eyes from chemicals, heat, or sharp objects.
Answer: What are safety goggles?
When an object changes its velocity, either by speeding up, slowing down, or changing direction, it is experiencing this.
Answer: What is acceleration?
If you push a shopping cart with twice the force, the cart’s acceleration will do this, according to Newton’s Second Law.
Answer: What is double?
The Law of Conservation of Energy states that energy cannot be created or destroyed, but it can do this.
Answer: What is change form (or transform)?
If a 10 kg object accelerates at 2 m/s², the force applied to it is this many newtons.
Answer: What is 20 newtons (F = ma)?
If a chemical spill occurs on your skin, this is the first step you should take to ensure safety.
Answer: What is rinse the area with water for at least 15 minutes?
The straight-line distance and direction between an object's starting point and its ending point is referred to as this.
Answer: What is displacement?
This is the equation associated with Newton's Second Law of Motion.
Answer: What is force equals mass times acceleration (F = ma)?
This is the total energy of all the particles in an object, often associated with temperature.
Answer: What is thermal energy?
This term describes a scientific prediction that can be tested through experimentation.
Answer: What is a hypothesis?
