This is the first in a series of “pop quizzes” for science fair competitors to practice their skills. Think of them as “time trials” for cycling or “scrimmages” for soccer. Feel free to leave your answers in the comment box.
Identify the dependent variable in each project idea.
Project Idea #1:
What is the effect of temperature on the viscosity of common kitchen liquids like maple syrup, vegetable oil, and milk?
a. temperature
b. viscosity
c. common kitchen liquids
Project Idea #2:
How much hydrogen gas can be produced from environmental waters of varying salinities?
a. amount of hydrogen gas
b. location of environmental waters
c. salinity differences
Project Idea #3:
Do spiders avoid coconut oil?
a. spiders
b. coconut oil
The dependent variable is the one that you will measure after making changes to the independent variable.
Answers:
Project 1 = b. viscosity;
Project 2 = a. amount of hydrogen gas;
Project 3 = a. the number of spiders
Can you identify the independent variable ???
