A student conducts the investigation shown in the diagram. In this experiment a paper cup hangs from a string tied to a single uncooked spaghetti noodle. The student measures and records the mass of a penny. The student then adds pennies to the paper cup one at a time.
Which question is the student most likely trying to answer with this investigation?
60
How much force will it take to break the spaghetti noodle?
How long should the string that holds the paper cup be in order to support the greatest mass of pennies?
How many spaghetti noodles will it take to hold up the mass of a penny?
How does the distance between the two chairs affect the amount of force it takes for the spaghetti noodle to break?

Conduct five trials, pulling a different side of each block each time
Conduct five trials, using a different scale to pull each block of wood
Conduct five trials, using a different table for each trial
Conduct five trials, pulling each block of wood in the same way for each trial

Q.
A student designs an experiment to test the effect of the width of a piece of elastic on the elastic’s ability to stretch. The student selects four pieces of elastic with different widths but the same length. The student then attaches blocks with different masses to the pieces of elastic. The results of the student’s experiment are shown below. What should the student do to improve this experiment?

Q.
A student observes that the craters on the moon are different sizes. The student designs an experiment to study the formation of craters. The materials for the experiment are marbles and a pan of flour. The student makes a hypothesis that the size of the craters made on the surface of the flour will depend on the height from which the marble is dropped. Some of the steps in the student’s experiment are described below. Which of these is most likely Step 3 in the student’s experiment?
