Do it Now Pg.12 What is/are the independent variable(s)? How do you know this?
Answer Slide What is/are the independent variable(s)? How do you know this? The Independent variable is the variable on the top row and it influences what happens to the dependent variable.
Fun Science Facts Water is made up of two elements, hydrogen and oxygen. Its chemical formula is H2O. Each molecule of water is made up of two hydrogen atoms bonded to a single oxygen atom. The existence of water is essential for life on Earth. Water has three different states, liquid, solid and gas. The word water usually refers to water in its liquid state. The solid state of water is known as ice while the gas state of water is known as steam or water vapor.

Thru 2 Pg 14 Analysis Questions: Data Table Activity Steps: Create a data table that records the following for each person at your table. Height Length of foot (measure all of these in centimeters) Color of hair Pick one other Quantitative and one additional Qualitative variable to record in the data table. Title your data table!!!!! Pg 14 Analysis Questions: What is/are the independent variable(s)? How do you know this? What is/are the dependent variable(s)? How do you know this? List one Quantitative variable Qualitative variable Can you have more than 1 independent variable? Why? Can you have more than 1 dependent variable? Why? Why do you think tables are used to record information?
Do it again Pg. 12 A scientist wants to know which type of material is a better insulator. So, she puts identical heat source behind walls of 3 different materials—Styrofoam, plastic and ceramic. On the other side of the wall, she put a thermometer to measure the temperature of the air. This will tell her how much heat energy is being transferred through the wall. What is the independent variable? What is the dependent variable?

Tues. Quiz #1 today-get out paper and your INB Due dates!!!!! Next class is the first notebook check for pages 1-19.
In: pg 16 Why do we say that graphs are “pictures” of data tables?
Answer Slide Why do we say that graphs are “pictures” of data tables? Because graphs show a picture of how the data looks.
Do it Now Pg. 16 Explain How a table helps to organize data. Answer in Blue ink Black ink or Pencil.
Answer slide Explain How a table helps to organize data. Table organize by using ordered pairs, having an excellent title and showing the units used in measuring variables. Data can be divided into two groups Quantitative and Qualitative.
Does ____________affect_____________? Thru 1 Pg. 17 How to figure out the independent and dependent variable… The independent variable will be completely filled in on the data table before you do the activity. Remember: Independent variable--assigned by experimenter, predictable, input, decided. Dependent variable-- affected by the independent variable, not regular or predictable, output, measured. Does ____________affect_____________?
Thru 1: pg 17 Does ___________________affect ________________? A scientist wants to know if the amount of snow fall in the Colorado Rockies during the winter affects the level of water in Lake Mead. So, he tracks the amount of snow that falls during the winter for 10 years. He then measures the level of water in Lake Mead for the same 10 years. What is the independent variable? What is the dependent variable? Does ___________________affect ________________?
Does ___________________affect ________________? A scientist wants to figure out if increasing the amount of caffeine given to a rat increases its heart rate. So, she gives different amounts of caffeine to 5 different groups of rats and measures their heart rates. What is the independent variable? What is the dependent variable? Does ___________________affect ________________?
Analysis Questions: PG. 18 What is the independent variable for the a. Single line graph b. Multiple line graph What is the dependent variable for the The ________ variable is on the x axis and the ________ variable is on the y axis. What conclusion can you draw from the data represented in the What is an advantage of a multiple line graph over a single line graph? 6. What is the purpose of a key on a multiple line graph? Thru 2 Pg Instructions 19 Line Graphs-You will be making a single line graph on one side of the paper and a multiple line graph on the other side. Population Growth in the Las Vegas Valley Single Line Graph Make a single line graph from the data table. Education and Income Multiple Line Graph Create a multiple line graph from the data table.
