5th graders have been studying force and motion. One group of students decided to repeat Galileo’s famous experiment for their science project. They designed an experiment to test the effects of gravity on heavier objects versus lighter objects. They dropped an iron ball and rubber ball from two flights of stairs. 3 trials runs were conducted and then data was recorded. Why did the students conduct 3 trial runs during the investigation?

• To formulate a hypothesis

• To increase reliability of results

• To test more than one variable

• To impress the teacher

In science class, students learned that friction is the resistance to motion when two object rub together. The students decided to design an experiment at home to compare friction on dry and icy surface.

Which question is most beneficial for this type of investigation?

• Is it faster to sled down an icy hill or down a rough gravel driveway?

• What is friction?

• What makes ice slippery?

• What effect does the height of the hill have on the distance an object travels?

In science class, students learned that friction is the resistance to motion when two object rub together. The students decided to design an experiment at home to compare friction on dry and icy surface.

What is the most appropriate tool to use when collecting data from the investigation?

• list

• graph

• table

• chart

When designing an experiment, why is it important to test only one variable?

• Testing one variable explains what caused the change once data has been gathered

• Testing one variable collects inaccurate data and repeats the investigation more than necessary

• Testing one variable decreases the reliability of the investigation

• It is not necessary to test only one variable

A science class completed a study on how objects move. All of the following would be considered appropriate when testing the effects of the force of motion on an object EXCEPT–

• throwing a baseball

• two teams play tug-of-war

• measuring the size of 2 marbles

• paddling backwards in a boat
