Tyler wants to run an experiment to find out the impact of temperature on the behavior of worms. He places one dish of 5 worms in the sun, and one dish of 5 worms in the shade.
After 3 days he comes back to find that all worms are alive in the shaded dish, but that only
two are alive in the sun dish.
What is the dependent variable in Tyler's experiment?
O how many worms are alive after three days
O the number of worms in each dish
O whether the worms are in shade or sun
O type of worm, size of dish, contents of dish
