Independent Variable Definition. An independent variable is the variable that is changed or controlled in a scientific experiment. Independent variables are the variables that the experimenter changes to test their dependent variable.
What is a independent variable?
200
By using a electronic scale or a balance scale.
How can you measure mass?
200
Volume
Fill in the blank.
the amount of space an object takes is an objects ______.
Because the matter molecules are more packed together in the the Baseball than in the tennis ball.
How is a tennis ball and a Baseball ball the same size but the Baseball ball is denser?
200
The control variable is the experimental element which is constant and unchanged throughout the course of the investigation.
What is a controlled variable?
300
Grams
What unit do you use to measure mass?
300
Water displacement
What is one way to find out a objects volume?
300
Hypothesis is a educated guess.Question is a way of asking what would happen or think and ask what it is.
What is the difference from hypothesis to question?
300
A cylinder or a beaker or a weighing machine
What materials can you use to calculate an objects density?
300
an observation that involves numbers and measurement
What is a quantitative observation?
400
weight is the gravitational force on a object and mass is the number of particals in a object.
What is the difference from weight and mass?
400
false.That is density.
true or false:a measure of the amount of mass in a given volume is volume?
400
CORRECT: This is true.
true or false:the scientific method is a series of steps followed to solve problems including asking questions, formulating a hypothesis, testing the hypothesis, collecting data, analyzing results and drawing conclusions.
400
false
true or false:an educated guess is density.
400
The effect or result of the change to the experiment, what is being observed or measured, the data
What is a dependent variable?
500
Weight would differ because weight is the gravitational force on a object and mass is the number of particals in a object and mass would never change unless you took those molecules away or added molecules.
How would weight be different on the moon and mass still stay the same no mater where you go?
500
mass + volume
what are the two things you need to calculate density?
500
6
how many steps are there in the scientific method?
500
you first calculate an objects density by dividing mass by weight.If your number is higher than one then it will sink.
how do you know if an object will float or sink in water?
500
true
true or false:qualitative observation is an observation that is made using your senses (sight, feel, smell, hear, taste) like color, texture, or smell.
