- A conversion factor is a multiplier equal to 1. - Choose a conversion factor that will make the units cancel, leaving the answer in the correct units.

Start with the given value: 15 hours 1 15 hours X 60 minutes X 60 seconds = 1 1 hour 1 minute Multiply: 15 X 60 X 60 = 54,000 seconds

Present Absent If the decimal point is present, start from the left. Then start from the first non-zero digit and count all of the numbers. Example: = 3 significant figures If the decimal point is absent, start from the right. Example: 150 = 2 significant figures

-A-Addition and Subtraction: 1. Perform the operation Example: – 7 = Round the result to the least-precise value. Example: – 7 = is the least-precise value = round up; 0-4 = round down So – 7 = 13

-M-Multiplication and Division: 1. Perform the operation Example: 15.0 x / = Round to the same number of significant figures as the least-precise measurement. Example: 15.0 x / = is the least-precise measurement and has 2 significant figures. So 15.0 x / = 1900

Let’s say that I’m trying to grow a flower, But I really want it to grow red, which isn’t a natural color for this type of flower I need to find a way to make grow differently…. To figure out how to do this I’ll use the Scientific Method!!

The first step I would take is to identify the problem: My problem is that I need this flower to grow red

The second step would be to identify the hypothesis: I predict that if I mix red paint into the soil it will grow red

The next step I would take would be to test my hypothesis: I will plant 4 flowers 3 of them will have red paint mixed into the soil and 1 of them will be the control group (have no paint mixed in)

After reviewing the results it seems that all 4 flowers grew in white… My hypothesis was wrong… I guess it’s back to the drawing board The next step is to form a conclusion,

So now after revising my hypothesis I’m now predicting that I’ll be able to grow the flowers red if I let them grow a bit then let them sit in a vase of water with food coloring for a few hours Now I’ll execute another experiment only this time I’ll be testing my new hypothesis

As I was reviewing the data… I found success!!!! My hypothesis was correct!!

In conclusi on, To dye a flower you have to first grow it then let in sit in a vase with a mixture of water and food coloring

The Scientific Method details a law which is testable and reproducible As opposed to detailing a theory which is not testable and is a collection of observations

The Independent Variable is the Variable that you control The Dependent Variable is the Variable that you measure I predict that if I add food coloring to the vase of water the flower will change color

Independent Variable goes on x axis Dependent Variable goes on y axis

To find the slope of a line, Take the rise divided by the run Pick two points on the line of best fit then

Linear Graph… Slope y=mx

Exponential y=mx²
