Will It Sink Or Will It Float?

This-N-That
100
This is the factor in an experiment that can change.
What is the variable?
100
If you know the density of an object, this is how you know if that object will sink or float in water.
What is if the density is less than one the object will float, and if the object is greater than 1 the object will sink?
100
This is one reason what scientists use their prior experiences to do.
What is nake predictions about what will happen under certain circumstances?
100
This is a prediction or statement that can be tested.
What is a hypothesis?
100
This is an example of technology that scientists often use to display their data.
What is a computer?
200
This is the sample that is treated exactly like the other experimental groups except that the variable is not applied to is.
What is control?
200
If a ball has a mass of 49.6g and a volume of 18.5cm3, this is its density.
What is 2.68g/cm3?
200
This is 2 examples of skills used in science.
What is observations and measurements?
200
This is listing what is known about a problem and possible ways to solve the problem.
What is making a plan?
200
This is one way to reduce bias in an experiment.
What is to take numerical measurements of the results?
300
This is the factor that is being measured.
What is dependent variable?
300
Cork has a density of 0.24, bone has a density of 1.7, brass has a density of 8.0, and oak has a density of 0.62. This is what each of these objects will do in salt water that has a density of 1.03.
What is cork will float, bone will sink, brass will sink, and oak will float?
300
This is what scientists do AFTER they complete their experiments.
What is communicate those results to other people?
300
This is a good way to organize and record your results and observations.
What is use a data table?
300
This is what you call giving partial information to get the results you want.
What is having a bias?
400
This is the factor that is changed in an experiment.
What is the independent variable?
400
This is the density of an object that has a mass of 25g and a volume of 36cm3, and will it sink or float in a lake.
What is 0.69 and it will float in the lake because it has a density of less than 1g/cm3?
400
These are the first and last steps of the scientific method.
What is recognize and identify a problem and drawing a conclusion?
400
In an experiment these are the variables that need to be controlled.
What is all variables but the one you are testing?
400
Predictions about what will happen is based partially on this.
What is prior knowledge?
500
On a line graph, you plot the independent variable on this axis. On a line graph, you plot the dependent variable on this axis.
What is the x axis? What is the y axis?
500
Most of an iceberg is actually below the surface of the ocean. This is an approximate density of the iceberg if ocean water's density is 1.03g/cm3.
What is about 1.2g/cm3
500
This is why scientist conduct multiple trials of their experiments.
What is to make their results more reliable?
500
If there are 2 companies that claim their bat is the one that makes the baseball go the farthest when hit, what is the best evidense to use to prove which bat is the best?
What is use a machine to swing the bat to hit balls with exactly the same force, and you measure how far the ball goes?
500
This is what worldwide distribution is called.
What is globalization?
