Physical Science Review

You are conducting an experiment involving five model rockets. Each model rocket is an identical design/shape and is launched from the same launcher using the same amount of force. The only difference between the rockets is their total mass, in grams. Which of the following testable questions is most likely being investigated using the four rockets?

• Does the speed of the rocket affect the height of the launch?

• Does the force used during a launch affect the height of the launch?

• Does the mass of the rocket affect the height of the launch?

• Does the shape of the rocket affect the height of the launch?

Performing multiple trials during an experiment is an important part of the scientific process. Which of the following statements best explains why?

• It makes the results more reliable.

• It gives you more information to analyze.

• It is fun.

• It allows you to change variables between tests.

You are given a table listing the properties of various test samples. The information includes color, mass, shape, and volume. Which of the following is true?

• The test samples could be solid, liquid, or gas.

• The test samples must be solids because their is a definite shape.

• The test samples must be liquids because their is a definite shape.

• The test samples are solids and gases because their is definite shape and volume.

In order to measure the volume of a marble, what process will you use?

• weighing with a scale

• water displacement using a graduated cylinder

• measuring with a ruler

There are three primary ways to increase the speed of dissolving: crushing up the solute, agitating the solution (e.g. stirring/shaking), or increasing the temperature of the liquid. With this in mind, which of the following statements is true regarding a solution of sugar and water?

• Adding ice to a mixture of sugar and water will speed up the dissolving process.

• Using hot water will speed up the dissolving of sugar in a sugar and water solution.

• Using a sugar cube instead of table sugar will speed up the dissolving process.

• Stirring the sugar and water mixture will slow down the dissolving process.
