What is quantitative data?
Jen set-up her experiment and begin to list everything she did step by step. By the time Jen finished her list, she had recorded 21 steps altogether. Step 1: Label three 7-ounce cups A, B, C. Step 2: Fill each 7-ounce cup with baking soda. Step 3: Half-fill a 14-ouce cup with vinegar. Step 4: Use clay to mold a volcano look alike around a 14 ounce cup. What is another name to describe the list that Jen made?
What are Procedures?
The part of the experiment that is changed on purpose to test its effects
What is Independent Variable?
After making observations and inferences along with research you create this which is a possible explanation of your observations and can be tested.
What is a hypothesis?
An explanation of the data collected in an experiment or observation
Interpretation
A representation of something in the natural world, typically too small or large to study up close.
What is a model?
As Savannah prepared to place all of her written parts on her science board, she noticed that one of the parts was not labeled. Savannah could not use her science fair packet to determine which part of the experiment it belonged to because she had left it in her desk at school. Savannah then decides to call a classmate from school and read her the unlabeled part to see if she could help. The unlabeled part read: Brand A diapers absorbed 10 milliliters more water than Brand B and 16 milliliters more water than Brand C diapers. It was interesting to see how Brand C diapers began to come apart after only a few minutes of soaking in the water. " What should Savannah's classmate tell her about the unlabeled part?
What is results from the experiment?
The variables that remain the same for all trial in an investigation so that the experiment can be VALID.
Hint * Things that are held constant during an experiment.
What are the controlled variable?
If your hypothesis is proven correct or incorrect this is the next step in the process.
What is repeat the test?
A personal belief or judgement that is not based on proof or certainty.

What is testing the length of a flame burning?
The factor that is being measured in the experiment.
What is Dependent Variable?

Explain how to design a valid experiment.
What is to create experiment procedures that help to answer the problem question? OR What is to carefully design/control the variables in an experinment (constant, IV, DV)?
Explain why the metric system is much "easier" to use (not WHY scientist use the metric system).
What is it is based on the powers of ten? (all you have to do is move the decimal point when converting between units because of this).
