SpongeBob wants to test to see if a new laundry detergent from SnailMart will do a good job of cleaning his square pants. He takes two equally dirty pairs of pants and washes one pair in the new detergent and water. He washes the other pair in just water. After 4 treatments, there is not difference in the cleanliness of his pants. What is the VARIABLE in SpongeBob’s experiment?
The new detergent

Monica noticed that a bird has made a nest and laid eggs outside her bedroom window. When the eggs hatch, Monica notices that the young birds are small and have no feathers. Three weeks later, she looks in the nest and sees the birds have almost doubled in size and have feathers. What characterisitc of living things has Monica observed?

Partick's breath is kicking like Bruce Lee. Pearl thinks a new brand of gum, KelpFresh, will get rid of his bad breath. Squidward suggests that he rinse his mouth twice a day with a new mouthwash, FishBreath. Patrick decides to chew KelpFresh and rinse his mouth with FishBreath twice a day. Three days later, his breath is back to normal. What is the variable in his experiment?
KelpFresh AND FishBreath

Joey observes a bright blue bird building a nest while walking to school. The next week, he notices that another bird had joined him in the nest. A month later he hears small chirps coming from the nest and sees the two birds taking turns going out for food. What characterisitis of living things has Joey observed?
The ability to reproduce.
