You will use these to make observations about the world we live in.
What are your senses?

This variable is the factor that is purposefully changed by the experimenter to test an effect.
What is the independent variable?
100
Every graph needs one of these so that someone reading a lab report or journal knows exactly what type of data was collected and the basic point of the experiment.
What is a good title?
100
The purpose of this is to answer why questions and learn more about the natural world.
What is science?

Appropriate footwear in the lab.
What is closed toed shoes?

The experimenter decides on the independent variable, dependent variable, constants, and control group during this step of the scientific method.
What is design an experiment?
200
The time it takes a person to run a mile depends on the amount of exercise that person gets. What is the dependent variable?
What is the time it takes to run a mile?

This is the horizontal axis on a graph.
What is the X-axis?

This is the first thing that you should do everyday when you arrive to science class.
What is pull out your warm-up sheet and begin working on the warm up?
300
These must be worn when working with glass, heat, or chemicals.
What are goggles?

Mary's data showed that warm water dissolved an Alka-seltzer tablet faster than cold or room temperature water. This is the step of the scientific method she is currently at.
What is drawing conclusions?
300
Hypothesis: The higher the temperature of water, the faster an egg will cook. What is the Independent Variable?
What is the temperature of water?
300
If you collect numerical data in a lab you must always have a graph and this in your "Data Analysis" section of your lab report.
What is a data table?

Mrs. Gamari taught here before coming to TMS.
What is Naugatuck High School?

When given a lab procedure to use to run an experiment, this is what you should do first.
What is read all directions carefully?
400
Sara said, "If geranium plants receive 24 hours of direct light, then they will grow taller than plants that receive 0 h or 12 h of light because they use the light to perform photosynthesis." This is the step of the Sci Meth she is doing.
What is developing a hypothesis?
400
Hypothesis: Lemon trees receiving the most water, produce the largest lemons. Identify the IV and DV.
IV- amount of water ; DV - size of lemons.
400
This type of graph is used to graph data over time.
What is a line graph?
400
This part of the scientific method is where the researcher explains why they are performing a certain lab and what they hope to learn.
What is the problem or the purpose?
500
You should never wear loose, big clothing in a lab - especially when you are working with this.
What is an open flame?

Your hypothesis is not supported by the data. These are your next two steps.
What is create a new hypothesis and test again?
500
An experiment was done with 6 groups of children to see if the amount of spelling practice affected their spelling test scores. Name at least 3 controlled variables that should be held constant so the only difference is the amount of practice.
TBD- what are the spelling words, the place where students took the test, general spelling ability, time given for the test, time of day the test was given, etc.
500
This type of graph is used to show how parts or percentages make up a whole.
What is a circle graph/pie chart?
500
This is the section of the lab report where the experimenter analyzes potential sources of error and their impact on the conclusions of the experiment.
What is the validity section?
