After STAAR

Students plan to investigate the different states of matter. They will measure the volume of water in three containers after five days. They make this table to organize the data. Which graph represents the volume of water most likely left in the containers after five days?

What will happen if Switch 2 is closed and the other switches are left open?

• Only the white bulb will operate

• None of the bulbs will operate

• Only the white and yellow bulbs will operate

• Only the blue and white bulb will operate

In this experiment a bucket hangs on one side of the seesaw, while on the other side a stack of books are set in the seesaw. The student adds a liter of water on the bucket at a time. Which question is the student most likely is trying to answer in this investigation?

• How long it take for the seesaw moves?

• How much liters of water will force the seesaw to move the books opposite direction?

• What is the distances between the books and the water?

• Will the seesaw supports the bucket of water?

The diagram (picture) shows two trials of an experiment in which a spring scale was used to measure force. Which statement is a reasonable conclusion?

• It takes more force to pull a load with more mass.

• It takes less force to move a load with more mass.

• The force needed to move a heavier load is the same as the force needed to move a lighter load.

• The mass of the marbles changes the mass of the dictionary.

The picture shows an athlete who is about to hit a baseball.

Which statement is true?

• The force of the bat will cause the baseball to change direction.

• The force of the bat will not change the direction of the baseball.

• The baseball will continue in the same direction after being hit by the bat.

• There will be no force applied to the baseball, because the baseball is moving faster than the bat.

Students design an experiment to determine how much force is needed to move blocks of wood of different masses slowly across a lab table. Which procedure should students include in their design?

• Conduct 5 trials, using a different scale to pull each block of wood.

• Conduct 5 trials, using a different table for each trial.

• Conduct 5 trials, pulling a different side of each block each time.

• Conduct 5 trials, pulling each block of wood in the same way for each trial.

The diagram (picture) shows two trials of an experiment in which a spring scale was used to measure force. This experiment can determine (figure out) -

• how mass affects (changes) the force needed to move objects

• how force affects (changes) the mass of two objects

• how the force used to pull a dictionary affects (changes) the mass of a box of marbles

• how the mass of a box of marbles affects (changes) the mass of a dictionary

Students drop the same heavy ball onto identical blocks of soft clay from different heights. For each height they measure the depth of the dent the ball makes in the clay.

Why is the depth of the dent different in each trial?

• The size of the ball changes.

• The material (type of matter) of the ball changes.

• The mass of the ball changes.

• The force of the ball when it hits the clay changes.

The higher the ball is held, the greater the impact will be.

What is one piece of equipment needed to test the hypothesis? ​ (a)  

AND how can the hypothesis be tested?​ (b)  

• a blanace

• a graduated cylinder

• a tape measure

• drop different balls from the same height

• change the mass of the ball

• change the size of the ball

• drop the same ball from different heights

What is the primary purpose of the STAAR Science test?

• To assess students' understanding of scientific concepts

• To evaluate students' physical fitness

• To test students' mathematical skills

• To measure students' reading comprehension
