What are meters used to measure?
Length
Where does the independent variable on the graph go?
X-axis
When would you use a bar graph?
When comparing two different objects
Why is it important for a scientists to have easily repeatable steps in an experiment?
To see if another scientist can replicate those results
Why is the metric system preferred by scientists?
It's simpler and easy to use
What do we use to measure the volume of an object?
Graduated Cylinder
When should a student wear goggles in a lab? (Must have all 3)
When dealing with fire, glass or chemicals
When would you use a line graph?
To show passage over time
What is the fourth step of the Scientific Method?
Gather your Data/Make a Data Table
What causes a meniscus?
The properties of water
What do we use to measure the mass of an object?
Triple Beam Balance
If you are making a bar graph and your independent variable is months and your dependent variable is amount of tuna born what could a title for that graph be?
Tuna born by month, Tuna Born vs Months
When do you use a scatter plot?
When finding out the relationship between two variables
What does an experiment need in order to be considered a theory?
Evidence
What is the unit for density?
G/mL, cm3, or kg/m3
What is the definition of mass?
The amount of matter in an object
In the metric system what temperature is the boiling point of water in Celsius?

Draw a negative correlation of a scatter plot on your board
A bunch of dots that start high and drop lower
Identify the IV, DV, and a possible control to the following experiment. Students of different age groups were asked to put the same jigsaw puzzle together, they were timed to see how long it took
IV: Students Age Groups
DV: Time Puzzle Took
Controls: May Vary
What is the metric unit that is 100x larger than the base unit?
Hecto
Using the density formula what would the formula for volume be?
M/D
What is the difference between a constant and a control group?
Constant: Something that stays the same during an experiment
Control Group: Doesn't get IV there for comparaison
What is the formula for finding the scale of a graph and what does the number you calculate mean?
Largest Number/Number of graph squares
That's the number you should put by each line
Identify the IV, DV, and a possible control to the following experiment. A study was done to find if different tire treads affect the braking distance of a car.
IV: Tire Treads
DV: Breaking Distance
Controls: May Vary
What is the formula for finding the volume of a solid using water displacement?
Final Volume - Initial Volume
Describe the difference between precession and accuracy and provide an example
Precession: Lots of Values Close together
Accuracy: Close to the actual value
If something has a mass of 41 g and a volume of 38 mL would it float or sink on water and why?
Density: 1.08 g/mL
Water Density is 1
