Technology!
This device measures weight.
Spring scale!
Which metric prefix means "Thousand?"
Kilo-
What is the SI unit for distance?
The meter!
The responding variable that you measure and graph on the y-axis.
Dependent variable!
Law or Theory?: For every action, there is an equal yet opposite reaction.
Law!
What's wrong with this measurement?: 140.23 mL
The estimated digit has to be either a 0 or a 5!
The formula for density is...
Density equals mass divided by volume!
D = m/v
What is the SI Unit for temperature?
The Kelvin!
The variable(s) that the experimenter keeps the same so that only one variable is being tested at a time.
Constant(s)!
Accuracy or Precision?: Bonnie shoots 10 arrows at a target. All the arrows land in the same-ish spot...nowhere near the bullseye.
Precision!
In a measurement, what do we call the digits that we read based on the lines on our measuring device?
Certain digits.
If you want to convert 230 cm to m, what will your "new" fraction be?
(1 m)/(100 cm)
What is the SI Unit for volume?
m3
The method for measuring the volume of an irregularly shaped solid in which you fill a graduated cylinder with enough water to cover the item, make note of that measurement, place the item in the cylinder, measure the new volume, and subtract the two volumes to find the volume of the object.
Water displacement!
Quantitative or Qualitative Observation?: The string is 12.35 cm long.
Quantitative!
This tool measures volume.
A graduated cylinder!
If you want to convert 1 day to minutes...what will your full factor label method setup look like?
(1 day)/() xx (24 hours)/(1 day) xx (60 min)/(1 hour)
What is the SI Unit for mass?
The kg!
An exact quantity that people agree on to use for comparison.
Certain or estimated?: The 0 in the measurement 345.60 g.
Estimated!
The measurement 1234.5 grams was made with a measuring device that has a smallest graduation of?
One!
You measure an unknown solid. The volume is 2.35 mL and the mass is 5.65 g. What is the volume? And, will it float in water?
The volume is 2.40 g/cm3. It will not float in water because its density is greater than 1 g/mL.
What is the SI Unit for weight?
The Newton!
A standard for comparison that helps to ensure that the results of the experiment are caused by the condition being tested.
The control group!
