NSO Science Review

The scientists at the hurricane center want to make a model to see how the winds in a hurricane affect the size of the waves produced. What type of model would help the scientists study this question?

• a drawing of a hurricane

• a chart showing the hurricane's path

• a computer simulation of different wind strengths

• a three-dimensional model of a hurricane forming

Brittany and Khloe used this model to explain a natural occurrence on Earth. How did this type of model help explain information to others?

• The model is a computer model that shows a simulation of the changes water undergoes.

• The model is an explanation in their minds that they used to remember the information.

• The model is a two-dimensional model where they recorded their pictorial representations over time.

• The model is a three-dimensional model that modeled a process that occurs in nature.

Raul created this investigation to model a natural occurrence. What type of information does Raul’s model provide?

• Raul created a computer model to simulate how the Earth changes.

• Raul created a 2D model to collect data on how soil, gravel, and grass affect the changing of the Earth’s surface.

• Raul created an explanation so that Harriet and Jackson could picture the model in their mind.

• Raul created a 3D model to collect data on how soil, gravel and grass affect the changing of the Earth’s surface.

Josiah wanted to make a model to predict the amount of fish that would be in the pond as the temperature changed. Which type of model would help Josiah learn about this the most?

• A. A 2D model showing the different types of fish that live in the pond.

• B. A 3D model that shows the depth of the water in the pond.

• C. A 3D model that shows the Earth’s movement around the Sun to account for the changing water temperatures.

• D. A computer model that changes the number of fish based on the temperature of the water.

A model is a representation of a system or concept, while a diagram is a visual illustration of information. Which of the following best explains the difference between a model and a diagram?

• A model is always physical, while a diagram is always digital.

• A model represents a system or concept, while a diagram visually illustrates information.

• A model is a type of diagram, and all diagrams are models.

• There is no difference between a model and a diagram.

Kaelan wondered which type of treat her cat liked the best. She placed 3 different treats in a row and placed her cat 5 feet away. She recorded which treat her cat would eat first. The data she collected is shown. How does Kaelan’s data support the idea that her cat prefers Treat 1?

• The cat chose each type of treat first at least once.

• The cat chose all the treats each time.

• The cat chose treat 1 first, more often than the others.

• The cat chose treats 2 and 3 first an equal number of times.

What evidence can Steve use to determine the tire pressure that gave the car the greatest speed?

• Steve should run a tire pressure of 12 psi, because every trial was quicker than the 16 psi tires.

• Steve should run a tire pressure of 12 psi, because every trial was slower than the 16 psi tires.

• Steve should run a tire pressure of 16 psi, because every trial is slower than the 12 psi tires.

• Steve should run a tire pressure of 16 psi, because it will be quicker than the 12 psi tires.

Mr. Robinson's class was investigating properties of minerals. Each group was testing the hardness of 3 different minerals. Here are their results. The groups looked at the results and discussed the differences in results. Which statement could NOT explain the results the Blue Table recorded?

• The Blue Table had different minerals to test than the other groups.

• The Blue Table recorded their data incorrectly.

• The Blue Table followed a different procedure than the other groups.

• The Blue Table used the same procedure and materials as the other groups.

Mrs. Hughes' class was investigating the speed of a toy car over different surfaces. Mrs. Hughes placed the same toy car on the top of the same ramp and each group placed a different type of rug at the bottom. The group then measured the time it took for the car to travel the length of the rug. The rug used by each group is shown. After collecting their data, the groups discovered their data looked very different. What is one reason the groups had different data?

• Each group used a different car to collect their data.

• Each group used a different ramps to collect their data.

• Each group used a different length rug to collect their data.

• Each group had a different person release the car at the top of the ramp.

Fiona measured the temperature in the metal, wood, and plastic prototypes. Riley measured the temperature in the glass habitat. What could be a reason the glass habitat has very different results than the other three?

• A. Fiona and Riley placed their habitats in different locations.

• B. Fiona and Riley used different types of thermometers to collect their data.

• C. Fiona and Riley used different heat lamps to warm the shelters.

• D. Fiona and Riley collected their data at different times of day.
