CCQIP stands for...?
Comment Connection Question Inference Prediction
200
What was the ingredient not added in the control?
Sugar.
200
What was the question we were exploring?
Is yeast alive? Does yeast metabolize sugar to form carbon dioxide?
300
Name ALL SIX Characteristics of Life
1. Has Cells 2. Complex Chemistry/Metabolism 3. Maintains homeostasis 4. Responds to external environment 5. Reproduction 6. Grows and Develops

Why do we use multiple samples or subject during an experiment?
An increased sample size allows for greater accuracy, there's less chance for error with more subjects.
300
Give an example of a sentence starter for a connection.
This is like __________ when...
300
Why is it important to have many test subjects?
Increased sample size results in more accurate answers.
300
What was the result of combining yeast, sugar, and water?
Carbon dioxide was created, inflating the balloon.

Define Reproduction
Production of offspring, making the new generation, etc.
400
Define control, as it is used in the scientific method.
The part of the experiment where you do not include the Independent Variable. The control lets you compare your results in the experiment
400
Give an example of a connection you could make to a text.
This reminds me of when I was in eighth grade and we...

What is the difference between growth and development.
Growth --> Organism gets larger, bigger. Development --> Organism changes in appearance, transforms throughout the life cycle.
400
Is yeast alive? Why or why not?
Yes - it metabolizes sugar. No - I don't have enough evidence to prove that it fulfills the the six characteristics.
500
Give an example of Metabolism.
Yeast + sugar ----> carbon dioxide (energy) humans + sugar ------> carbon dioxide (energy) plants + sunlight ------> sugar (energy)
500
Compare and contrast the independent and dependent variable? What is similar about them? What is different?
Independent Variable: the part of your experiment that you will test (vary) to answer your hypothesis Dependent Variable: what occurs in response to the changing independent variable The scientist does not change or modify the dependent variable, it is only measured in response.
500
Define inference.
Drawing a conclusion
500
Give an example of the body maintaining the internal environment in response to an external stimulus.
Increase in body temp, decrease in body temp, blood sugar, etc.

When you make bread, if you just mix flour, sugar and water, the dough does not rise, and the bread will be flat and hard. If you include yeast in the bread dough, then the dough rises and the bread is bigger and fluffier. Can you explain how the yeast helps the bread dough to rise?
yeast + sugar + water + flour ------> carbon dioxide in bread = fluffy bread. Without sugar, no carbon dioxide is created, and the bread will not rise.
