Scientific Method
The Scientific Method has this number of steps.
What is 6?
Define observation.
Using 5 senses to describe something.
Name 2 possible units for measuring length.
cm, inches, m, yards, feet, km, miles...
The letter that represents the vertical axis on a line graph.
y- axis.
What is the formula for finding density.
Density = Mass/Volume
Define Hypothesis.
A hypothesis is an if then statement which predicts the outcome of an experiment.
Define volume.
This measures kinetic energy or heat.
Temperature.
Explain the relationship between variables in a direct relationship.
Variables change in the same way.
If you take a block of wood and cut it in half, what happens to the density?
stays the same.
Give a possible hypothesis for the following problem: Would dogs who are fed vegetables lose weight?
If you feed a dog vegetables, then they will lose weight.
Define independent variable.
The factor being changed in an experiment.
The amount of matter in a object, measured in grams.
Mass
Explain why you would use a graph in science.
Display information gathered in an experiment.
Density Rule 3(hint- temperature change): When a substance is ____________, the density increases.
Cooled.
Explain what the Scientific Method is used for.
To investigate scientific problems and research information.
Define Density.
the amount of mass in a given volume.
Name the tool used to measure mass.
Triple Beam Balance.
Explain what is represented in a graph that shows a cyclic relationship.
Repeating pattern - looks like a wave
If an object is less dense than water, will it float or sink?
Float.
Name 3 steps of the Scientific Method.
Collect Information, Hypothesis, Analyze Data, Conclusion, State the Problem.
Define Dependent variable.
changes as a result- what you are measuring in an experiment.
Name the tool used to measure the volume of an irregular object - such as a rock.
graduated cylinder
This letter represents the horizontal axis on a line or bar graph.
x- axis.
