I am testing whether my plot flowers will bloom early by using fertilizer.
If I where to set up an experiment to test this.
What would my independent variable be?
Whether fertilizer is present or not.
What is the formula for calculating density?
Density = m/V
Put the following in scientific notation:

has 4 sig figs
I am testing whether my plot flowers will bloom early by using fertilizer.
If I where to set up an experiment to test this.
List three controlled variables that would apply to this experiment:
Plot/ pot size and material, amount of water, watering time, amount of sun, soil composition, any others?
If irregular shape object (like a rubber duck) how would you measure the volume?
By water displacement
Solve: (9*10^-6)-(5*10^-5)
(4.1*10^-5)
How many significant figures are in:
0.030014500*10^-6

I am testing whether my plot flowers will bloom early by using fertilizer.
After I analyze my data:
Which variable would go on the x axis
Whether the plant grew with fertilizer or not.
Here is the equation for the volume of a cylinder
V=pir^2h
calculate volume, then calculate density, put in your answer in scientific notation
Height:200cm
Radius: 12.5cm
Mass: 30,000g
Volume=98175cm^3
Density=(3.05*10^-1)g/(cm^3)
