What is the Hypothesis?
Base unit of mass for the metric system.
What is gram?
You have a metal block with a mass of 300 grams and a volume of 100 cubic centimeters. What is the density of the metal?
Solution: Density is calculated using the formula:
Density=VolumeMass
Given:
Plugging in the values:
Density=100 cm3300 g=3 g/cm3
Systematic process used to explore observations and answer questions about the natural world
What is Scientific Method?
The system (sphere) that includes all water.
What is Hydrosphere?
The proper sentence structure for a hypothesis.

Unit used to describe volume.
What is cm3/mL?
A cylindrical container holds 500 milliliters of oil. The mass of the oil is 400 grams. What is the density of the oil?
Solution: Density is calculated using the formula:
Density=VolumeMass
Given:
Plugging in the values:
Density=500 cm3400 g=0.8 g/cm3
Repeated test of a hypothesis where measurements and observations are collected
What is Experiment?
The two spheres that interact when dust blows in the wind.
What is lithosphere and atmosphere?
The variable that we measure.
What is the dependent variable?
Unit used for density.
What is g/mL or g/cm3
Convert 7.5 kilometers to meters.
Solution:
1km=1000m
7.5km x 1000m/1km = 7500 m

What is Control group?
The branch that would include the study of stars.
What is astronomy?
The graph used to show change in data over time.
What is a line graph?
Method used to calculate volume of irregular shaped object.
What is water displacement?
volume of (water+object)-(volume water)=volume object
Convert 3.5 miles to feet using dimensional analysis.
Conversion Factor: 1 mile = 5280 feet
We set up the conversion as follows:
3.5miles×5280feet/1mile
Notice that the unit “miles” in the numerator and denominator cancel each other out, leaving us with:
3.5×5280feet
Now, perform the multiplication:
3.5×5280=18,480feet
A factor in an experiment which the experimenter changes
What is Independent variable?
The word that describes how the spheres interact.
What is interdependent?
Samantha would like to know how different liquids effects the growth of her sunflower plants. In Samantha’s experiment, she hydrates her 5 sunflower plants with: a) vegetable oil, b) vinegar, c) water, d) Coca-Cola and e) Monster energy drink. Identify a constant in the experiment.
What is Same plant, What is same amount of light, What is same size pot and same type of soil?
Equation used to calculate density.
What is D=m/V?
Convert 2.3 miles to inches
conversion factors: 1 mile = 5280 ft and 1 ft = 12 inches
First, convert miles to feet:
2.3miles×5280feet/1mile =2.3×5280feet
Calculate the number of feet:
2.3×5280=12,144feet
Next, convert feet to inches:
12,144feet×12inches/1ft =12,144×12inches
Calculate the number of inches:
12,144×12=145,728inches
So, 2.3 miles is equal to 145,728 inches.
