Melika made a model to help understand why craters on the moon are different sizes. She represented the moon’s surface with a pan of flour. Melika represented objects that hit the moon with marbles. She thinks that dropping marbles from a greater height will make the crater’s diameter larger.
What should she change in her experiment to test her hypothesis?
the weight of the marbles
the kind of flour in the pan
the height she drops the marbles from
the size of the marbles
Devon thinks wrapping a cotton towel around a jar of hot water will keep it warmer than without any wrapping at all. He is designing an experiment to determine whether construction paper, a paper towel, a cotton towel, or no wrapping at all will keep the water in the jar warmer.
What tool does he need to use to test the temperature of the water?
graduated cylinder
beaker
thermometer
triple beam balance
Ben observed that puddles outside seem to disappear more quickly when it is a sunny day. He decided to test this by setting up an experiment in which he placed a graduated cylinder with 10 ml of water in a dark closet and a graduated cylinder with 10 ml of water by the window. Each day he measured the amount of water.
What did Ben change in this experiment?
the amount of sunlight on the water
the amount of water in the cup
the kind of cup
