Marcie wants to see if a new bug spray will decrease the amount of bites she gets in one day. She sprays the bug repellant on one arm and the other arm is left without it. She then
records the number of bug bites she gets on each arm after 2 hours.
Create a hypothesis in an If...then format.
Identify the independent variable (IV), the dependent variable (DV) and 2 constant variable
for this experiment.

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
