Which activity would be an appropriate first step when designing an experiment?
A) reporting a conclusion based on multiple experimental trials
B) researching the problem, using information from a variety of sources
C) creating a data table to organize experimental observations
D) repeating the experiment with a different hypothesis
B) researching the problem, using information from a variety of sources
what is the experimental group?
group that is exposed to the independent variable
An experiment was carried out to determine whether drinking caffeinated soda increases pulse rate. The pulse rates of two groups of people at rest were measured. Group A was then given caffeinated soda and group B was given caffeine-free soda. One hour after drinking the soda, the pulse rates were measured. The participants in the experiment were all the same age, and they were all given the same amount of soda. What is the dependent variable
A) type of soda given to each group
B) amount of soda given to each group
C) pulse rate of each group
D) age of participants in each group
C) pulse rate of each group

D) scientific observations
A) a single variable
What is the control group?
Group in an experiment not exposed to independent variable serves as a comparison

milk or not/ material, amount of time spent
