Science FAST Review

What is wrong with the procedures that Liam followed for this experiment?

• He did not make a prediction about the electromagnet.

• He did not pick up different objects with the electromagnet.

• He did not record the results of his experiment in a graph or chart.

• He did not perform an experiment because he does not have a variable.

A student rolled four toy cars down the same ramp and recorded his data in a table. Which statement best explains the data?

• Car 3 traveled the greatest distance because it had the greatest mass.

• Car 1 traveled the shortest distance because it had the shortest length.

• Because they had the same length, Car 2 and Car 4 traveled the same distance.

• Because they had greater mass, Car 2 and Car 4 each traveled a greater distance than Car 1 and Car 3.

Josie is conducting an investigation to see if more worms can be found in wet soil or in dry soil. Which best describes why Josie should write down her procedure for her investigation?

• So that the investigation can be published in a science magazine

• So that others can repeat the investigation and compare findings

• So that the results of Josie’s investigation can help fishermen find worms more easily

• So that the results of Josie’s investigation will prove that worms like wet soil better

Clay is measuring the distances three different cars travel when released down the same ramp. Which best explains why Clay should repeat this experiment several times?

• Repeating the trial several times will provide the most accurate results.

• Repeating the trial several times will give each car a chance to travel farther.

• Repeating the trial several times will allow Clay to choose the best results to use.

• Repeating the trial several times will allow the tires on each car to warm up, allowing them to travel farther.

The students in Mr. Johnson's class conduct an experiment to determine the effect of sunlight on plant growth. The class puts all of their results in a chart. Carla's data are much different from everyone else's results. Which statement best explains why this may have happened?

• Carla did not add her results to the chart correctly.

• Carla was more careful than the other students.

• Carla performed a better experiment than the other students.

• Carla did not follow the steps of the experiment correctly.

Which of the following examples best shows how a person uses the "scientific method" in an investigation?

• Emily wonders if plants grow better in sunlight or in the dark. She sets up two plants, one on a sunny windowsill and one in a dark closet. She measures and records their growth every 3 days.

• Max enjoys looking at the stars at night. He notices an object that is moving quickly across the sky and decides it is a satellite.

• Olivia just got a new kitten. She reads a science book about cats to learn about their behavior.

• Liam observes changes to a fallen tree trunk. He identifies different types of invertebrates that are found on and around the logs.

Which statement is best shown by Kiley's investigation?

• Objects that are the same size have shadows that are the same size.

• Objects that are farther from the flashlight appear larger than those that are closer to the flashlight.

• Objects that are closer to the flashlight appear larger than those that are farther away.

• Larger shadows belong to objects that are larger, and smaller shadows belong to objects that are smaller.
