Metric System
This is the tool of measurement used to find mass in the metric system.
Triple Beam Balance
Always ending with a "?", this converts general wondering and interest into a channeled line of thinking and inquiry.
Question Posed
This is a variation that does depend on that of another. The result of what the scientist has changed.
Dependent Variable
These are the 6 steps of the Scientific Method
Question, Research, Hypothesis, Experiment, Data & Analysis, Conclusion
Convert 4.5g into mg:
4,500mg
This unit of length in the metric system is used to measure far distances. (prefix+base unit)
Kilometer
This is the quantity of matter in an object.
Mass
This is a variation that does NOT depend on that of another. A factor that scientist has changed.
Independent Variable
A proposed answer to the question, this can be tested in an experiment. ("If..., then...")
Hypothesis
Convert 40 cm to km:
0.0004 km
This is the concave point in a graduated cylinder used to measure volume
Meniscus
These are conclusions or deductions based on observations. The process of drawing a conclusion from given evidence.
Inferences
These are kept the same in both the controlled and experimental groups.
Constants
Write an acceptable hypothesis for this question: Does the amount of iron in soil affect plant growth?
If I add iron to soil, the plant's growth will be smaller.
Convert 300 mL into L:
0.3 L
True or False: to measure out 5g of salt, you would have to place a piece of paper towel on balance; find its mass; move rider to 5g plus the mass of the paper; add table salt until pointer rests at 0.
True
The amount of water an object replaces is called this.
Displacement
This is the group where nothing has changed and is used for comparison.
Controlled Group
Write whether this a is quantitative or qualitative observation: the dinosaur fossils were glossy and smooth.
True or False: 10 mm = 1 cm
True
These are the steps to finding the volume of an irregular object.
Drop the object into a graduated cylinder. Calculate the difference between the initial and final volume measurement.
You do this to develop a test to support or not support your hypothesis.
Create an experiment
This is the group where a variable has changed.
Experimental Group
Make an inference based on this observation: the opposing team's basketball players are taller than our team's players.
The opposing team is going to score more points.
Convert 547.8 mm to m:
0.5478 m (look at your Metric Units Ladder!)
