Example Questions
Example Question #55 : Physical Science
Jessica cut up a large piece of paper and glued it to a poster board and made it into the shape of a robot. She added cut up tinfoil, broken beads, and small pieces of tile for decoration.
Which answer choice is an evidence-based statement about Jessica's project?
Robots can only be created out of metal.
This is an example of creating something new out of the smaller pieces of a larger object.
This is an example of a simple project that anyone can do with these materials from their house.
Jessica's robot sounds very pretty and creative.
This is an example of creating something new out of the smaller pieces of a larger object.
Jessica created a robot picture out of broken materials and pieces of something larger broken down into smaller bits. Some of the answer choices are personal opinion rather than evidence-based, and others are incorrect statements. "This is an example of creating something new out of the smaller pieces of a larger object." is a true and accurate statement and based on evidence from the information provided.
Example Question #2 : Construct An Evidence Based Account Of An Observation
Observe the photo below. Which answer choice is constructing an evidence-based statement based on observation?
Building blocks can be made into anything you can imagine, but once they are built, they cannot be taken apart again.
Building blocks are a fun toy to play with and allow children to work together.
Building blocks are individual pieces but can be put together and taken apart to make something new.
Building blocks can only be made into the design they were constructed for.
Building blocks are individual pieces but can be put together and taken apart to make something new.
Creating an evidence-based statement or account means that no personal opinion or thought can be included, and it must be able to be supported by an investigation or experiment. The answer choice that is based on evidence and observation is, "Building blocks are individual pieces but can be put together and taken apart to make something new." This is something that could be tested and also has no personal thoughts or opinions included.
Example Question #56 : Physical Science
Which statement is based on opinion instead of evidence?
Mosaic pieces of artwork are examples of breaking up larger pieces and putting them together to make something new.
Mosaic art pieces can come in multiple colors, patterns, and designs.
Pieces of mosaic artwork are made of tile, glass, ceramic, and other pieces of material.
Artists love to make mosaic pieces of artwork.
Artists love to make mosaic pieces of artwork.
Personal opinion statements will include thoughts and feelings from the author. "Artists love to make mosaic pieces of artwork." is a statement that provides for individual ideas and makes a sweeping statement that "artists love to make mosaics." This is not something that can be proved scientifically and is just one person's opinion.
Example Question #1 : Construct An Evidence Based Account Of An Observation
The following statement is based on evidence. " I observed an artist ripping up a newspaper and dipping it into a mixture of liquids. She then laid it carefully around an inflated balloon and left it to harden. When she finished, she popped the balloon and peeled it off the newspaper. It left behind a solid bowl."
False
True
True
This statement is accurate and based on evidence. There is no personal opinion or description of the bowl besides scientific observation. Had the author included information like "the bowl was beautiful" or "the artist was very talented." then personal thoughts would be integrated and no longer allow this to be completely evidence-based on observation.
Example Question #5 : Construct An Evidence Based Account Of An Observation
Mike uses building blocks to make a racecar, track, and bleachers for viewers. He tears it down and decides to make a castle and drawbridge for his next creation.
Based on this information, Mike is breaking apart a whole object and using the pieces to make something new.
False
True
True
Mike is indeed using pieces of a whole to create something new. He has broken the racetrack, car, and bleachers up, and is using the same blocks to make a building. Disassembling something is possible to create something new.
Example Question #57 : Physical Science
Which observational data is based on evidence and NOT an opinion?
I saw Sawney go for a run every morning at 9:00 AM while I was out watering my plants in March.
Half of the basketball team wears blue sneakers. Our team is losing this season, so we need to change our shoe colors.
Jack measured his tomato plant in his garden every day. It grew to four feet tall over the summer. It is his favorite plant.
Lexi thinks she is a better bowler when she uses the pink ball, but she likes the purple ball the best.
I saw Sawney go for a run every morning at 9:00 AM while I was out watering my plants in March.
Observational data is information that can be collected with our five senses. It the account must be based on evidence, there should be data provided and no mention of personal thoughts, feelings, or opinions. "I saw Sawney go for a run every morning at 9:00 AM while I was out watering my plants in March." This statement using factual evidence and does not include personal opinion.
Example Question #1 : Creation Of New Objects From Existing Objects
Jessica cut up a large piece of paper and glued it to a poster board and made it into the shape of a robot. She added cut up tinfoil, broken beads, and small pieces of tile for decoration.
Which answer choice is an opinion-based statement about Jessica's project?
Twelve of the beads that Jessica used were red, and fifteen were orange.
Jessica's robot was one-foot tall and six-inches wide.
The small pieces of tiles used to be whole before they were broken.
While cutting up the tinfoil, Jessica cut her finger, and it hurt very badly.
While cutting up the tinfoil, Jessica cut her finger, and it hurt very badly.
Jessica created a robot picture out of broken materials and pieces of something larger broken down into smaller bits. Some of the answer choices are evidence-based, while one is a personal opinion. "While cutting up the tinfoil, Jessica cut her finger, and it hurt very badly." includes a personal opinion. It may be factual that she cut her finger, but the degree of pain felt is an opinion and subjective for each person.
Example Question #2 : Creation Of New Objects From Existing Objects
Look at the photo below. Which answer choice is constructing an evidence-based statement based on observation?
There are blocks of many colors in this pile. They can be used to build many different things.
There blocks of different sizes and shapes in this pile. I only like using the red blocks.
These blocks are all equal size and the same shape. They look fun to play with.
These blocks are to build a rocket ship. Once the ship is created, it cannot be taken apart.
There are blocks of many colors in this pile. They can be used to build many different things.
Creating an evidence-based statement or account means that no personal opinion or thought can be included, and it must be able to be supported by an investigation or experiment. The answer choice that is based on evidence and observation is, "There are blocks of many colors in this pile. They can be used to build many different things." This is something that could be tested and also has no personal thoughts or opinions included.
Example Question #3 : Creation Of New Objects From Existing Objects
Which statement is based on opinion instead of evidence?
Small pieces of materials can be put together to make something new.
Large tiles can be broken into smaller pieces to make mosaic artwork.
Mosaic artwork looks best when made in greens like the piece in the photo.
Mosaics can be made of materials other than tiles.
