Leah, LaRenda, and Gabi decide to test what factors influence water absorption by an egg. They remove the shell from 3 eggs by dissolving them in vinegar. They create three different water solutions. One is pure, 100% distilled water, a second is 50% water/50% corn syrup, and the third is 100% corn syrup. The mass of each egg is measured before they are put into a single solution for 24 hours. The mass of the eggs is then measured, and the data recorded below:

In this experiment, the independent variable they are testing is

a)

change in the mass of the eggs

b)

the ending mass of the eggs

c)

the amount of time they were in the solution

d)

a)

"If an egg is placed in corn syrup, then it increase in mass."

b)

“If an egg is placed in vinegar overnight, then its shell will dissolve.”

d)

“If an egg is placed in a pure water solution, then the egg will increase in mass.”

Ada and Elijah have decided to do an experiment testing how sunlight affects plant growth. The students choose the same type of plants, soil, pots and amount of water they give the plants. They also make sure each plant is put in their designated area for the same amount of time each day. One plant is placed outside; one in front of a window that only gets light for 1/2 the day, and one in a closet. The students collect data every day for two weeks. Their results show that the plant outside grew the most and the plant in the closet had the least amount of growth.

a)

type of plants

b)

type of soil

c)

the amount of light

d)
