5th Science STAAR Review Game 1

1. Students conducted an investigation in which they let the same car roll down the same ramp in three different locations in their school with three different floor types, as shown below. Which of the following questions was this investigation most likely designed to answer?

• A. How does the mass of a toy car affect its speed?

• B. How does friction affect the distance a toy car rolls?

• C. What mechanical advantage does an inclined plane give?

• D. Why does gravity make a toy car roll down a ramp?

2. Students are going to conduct an investigation in which they will need to measure the speed of an object. Which two tools will they need to get the appropriate measurements to determine speed?

• A. Balance & meter stick

• B. meter stick & ruler

• timer & safety goggles

• meter stick & timer

Students dropped marbles into graduated cylinders filled with the same amount of three different liquids. The time it took the marble to reach the bottom was recorded in the table below. The procedure was repeated three times for each liquid. The students believe that the measurement of 2.2 seconds for Trial 3 of Liquid 3 is incorrect. Which of the following is the most likely explanation of what caused the error?

• A. Liquids 1 and 2 became warmer after several trials

• B. The stopwatch was started too late for the one trial

• C. All the marbles became coated with the different liquids

• D. The graduated cylinder was too narrow for the marble

4. Students are going to test how the mass of an object affects its movement. They will use an electric fan to blow air on a set of playground balls and measure how far they travel before stopping. What is an important component of the design of this investigation?

• A. The fan will need to have low, medium, and high settings

• b. Students must measure the distances in millimeters.

• c. The investigation must be done outside on the playground

• d. Students need balls of different masses, but of the same size.

5. Students are investigating the forces that act on a wagon as it rolls down a hill. Which of the following would be the best way for students to determine how the mass of the wagon affects the speed it rolls down the hill?

• a. Attaching rubber bands to the wheels of the wagon

• b. Starting the wagon from different heights on the hill

• c. Pushing the wagon with different forces at the start

• d. Adding one, two, or three bricks to the wagon

Which of the following is a process that creates the sediments that form sedimentary rock?

• A. Wind, water and ice breaking rock into smaller pieces

• b. Heat from the earth melting rock below the surface

• c. Volcanoes putting out lava that cools to form new rock

• d. Continents pushing together to fold layers of rock

Coal and oil formed in places that, in ancient times, produced large amounts of –

• a. thermal energy

• b. organic matter

• c. ocean currents

• d. volcanic activity

Which of the following locations would most likely produce sedimentary rock after much time has passed?

• A. A beach where sand is being deposited

• b A mountain that receives snow year round

• c. A volcano that erupts frequently

• d. A rocky desert that is windy all the time

In order for plants to be changed into fossil fuels, the plants must first die, and then be –

• a. decomposed by bacteria

• b. eaten by consumers

• completely dried out

• buried deep underground

10. Small particles of broken down rock can be formed into sedimentary rock when they are buried and then –

• A. melted completely because of extreme heat

• b. compressed and cemented together

• c. pushed upward and exposed to wind and water

• d. contaminated by underground nuclear material
