Question

Marjorie is conducting a science experiment to measure the amount of pollution produced by cars that used gasoline containing different amounts of lead. Identify the dependent and independent variables.(1 point)
Responses

i= gasoline containing different amounts of lead
d= type of car
i equals gasoline containing different amounts of lead d equals type of car

i= the amount of pollution
d= gasoline containing different amounts of lead
i equals the amount of pollution d equals gasoline containing different amounts of lead

i= gasoline containing different amounts of lead
d= the amount of pollution
i equals gasoline containing different amounts of lead d equals the amount of pollution

i= conducting a science experiment
d= the amount of pollution

Answer 1

i= the amount of pollution

d= gasoline containing different amounts of lead

The dependent variable is the amount of pollution, as it is the variable being measured and affected by the independent variable. The independent variable is the gasoline containing different amounts of lead, as it is being manipulated and can potentially have an effect on the dependent variable.

Answer 2

This month’s activity for the science club is to measure the temperature of the water at different depths in Lake Washington. The club found that the temperature of the water varied. Identify the dependent and independent variables.(1 point)

Responses

i= different depths of Lake Washington
d= this month’s science activity
i equals different depths of Lake Washington d equals this month’s science activity

i= different depths in Lake Washington
d= the temperature of the water in Lake Washington
i equals different depths in Lake Washington d equals the temperature of the water in Lake Washington

i= this month’s activity for the science club
d= the temperature of the water in Lake Washington
i equals this month’s activity for the science club d equals the temperature of the water in Lake Washington

i= the temperature of the water in Lake Washington
d= different depths in Lake Washington
i equals the temperature of the water in Lake Washington d equals different depths in Lake Washington

Answer 3

i= the temperature of the water in Lake Washington

d= different depths in Lake Washington

The dependent variable is the temperature of the water in Lake Washington, as it is the variable being measured and affected by the independent variable. The independent variable is the different depths in Lake Washington, as it is being manipulated and can potentially have an effect on the dependent variable.
