Matter
The two things that are used to define matter
What are volume and mass
A hypothesis is
What is a testable idea that leads to scientific investigation
Technology can be both
What are simple and complicated
The formula used to find density
What is D=M/V (What is density is equal to mass divided by volume)
Definition of matter
What is anything that has mass and takes up space
Name two things that aren't matter
What are light and sound (answers may vary)
The difference between an independent variable and a dependent variable
What is an independent variable is something the scientist changes while a dependent variable is the result of an independent variable
Simple technology is defined by these characteristics.
What are being easy and inexpensive, requiring no electrical energy, and are easy to use and understand.
The formula used to find the volume of a regularly shaped object
What is lwh (What is length times width times height)
What is mass
What is the amount of matter in an object
Air is matter even though we can't see it because
What is air takes up space and has mass though very little
Data is
What is carefully tracked information the scientist collects during the experiment
Complex definition is defined by these characteristics.
What are, using electrical energy, being expensive, requires knowledge in many fields, and being hard to understand.
The formula used to measure mass using density and volume
What is DV=M (What is density times mass equals volume)
The definition of weight
What is the measure of gravitational force
The difference between mass and weight
What is mass is the amount of matter while weight is the amount of gravitational force on an object
Important characteristics in a good investigation
What is having well documented and organized data, having only one independent variables, being repeated several times by many other scientists and the original scientist, and answering questions formed by others.
A trade-off is
What is something one must give up in order to have another advantage and for the design to fit within the constraints.
How to convert c3 to mL
What is 1 c3= 1 mL
The definition of technology
What is the application of science for practical purposes
Density is
What is the amount of mass in one c3
State the main parts in an investigation
What is making a hypothesis, planning and conducting an experiment, and finally collecting and organizing the information then analyzing it.
The main steps of the engineering design process are
What are brainstorming, making a prototype, testing and fixing it.
How to find the density of an irregular shaped object
What is water displacement
The definition of science
What is the application of science and math for practical purposes
