Example Question #7 : Construct An Evidence Based Account Of An Observation
Which statement is based on opinion instead of evidence?
Mosaics can be made of materials other than tiles.
Small pieces of materials can be put together to make something new.
Mosaic artwork looks best when made in greens like the piece in the photo.
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.
Personal opinion statements will include thoughts and feelings from the author. "Mosaic artwork looks best when made in greens like the piece in the photo." is a statement that talks about preferences and individual subjective thoughts. This is not something that can be proved scientifically and is just one person's opinion.
Example Question #3 : Construct An Evidence Based Account Of An Observation
The following statement is based on evidence. "Kaitlyn smashed colored tiles with a hammer and collected the broken pieces. She picked her favorite color tiles to make a portrait of her mother. She thinks this will be her best artwork ever and is excited to share it for Mother's Day."
False
True
False
This statement is not based solely on evidence. There are personal thoughts and information included. Kaitlyn mentions her favorite color that this will be her best artwork, and her feelings about excitement; these are all opinions and not factual, evidence-based statements.
Example Question #11 : Creation Of New Objects From Existing Objects
Jackie says that she can take a piece of paper, cut it into tiny shapes, and put it back together again to make something new. Her friend Amanda said that isn't possible and once the paper has been cut it is ruined.
Who is correct and why?
There is not enough information to make a decision.
Jackie; larger objects can be disassembled or broken apart to form new things
Neither; both Jackie and Amanda are wrong
Amanda; cutting the paper destroys it, and it cannot be put back together or turned into something new
Jackie; larger objects can be disassembled or broken apart to form new things
In this scenario, Jackie is correct, and Amanda is wrong. Objects can be disassembled or broken apart to form new objects. In the case of a piece of paper, it is much like a puzzle, the pieces can be put back together to reform the paper, or they can be formed into something new by changing their order.
Example Question #12 : Creation Of New Objects From Existing Objects
Which of these photos is an example of disassembling something into small places to make something new?
The photo of the mosaic artwork is a perfect example of making something new out of the small pieces of another object. Artists will take small pieces of tile, glass, or other materials and put them together to make a new creation. It is possible to disassemble something and create something new!
Example Question #1 : Disassemble An Object Made Of Small Pieces Into A New Object
Tabitha's teacher gave her five snapping cubes and told her to create at least ten different shapes using only those cubes. How is it possible to make so many different designs?
It is not possible; her teacher is giving her an impossible task.
Tabitha can just make one shape and then turn it around and tell her teacher it is different.
Objects can be disassembled, and the parts can be used to make something new.
Snapping cubes are flexible so you can bend them.
Objects can be disassembled, and the parts can be used to make something new.
Tabitha's teacher has not given her an impossible task. This is something that can be done because larger objects can be broken down into smaller pieces and then be made into something new. Tabitha could take the cube apart and put the cubes back together in a different order, which would make something unique.
Example Question #13 : Creation Of New Objects From Existing Objects
Which photo represents whole objects being broken down into smaller pieces to make something new?
The photo that represents an object being broken down into smaller pieces to make something new is the pizza. The individual ingredients are added to make the entire pizza. Olives are cut up, tomatoes crushed, peppers cut, etc. to be added onto the crust and baked. This is an example of something new being created from the smaller pieces of objects being broken up.
Example Question #5 : Disassemble An Object Made Of Small Pieces Into A New Object
A new object can be created using the pieces of something else.
False
True
True
The statement presented in the question is true. You can take an object, break it into small pieces, and then put it back together to create something new. If you were to build a castle with blocks, you could knock it down and build something else instead. This is a simple example of making something new out of the pieces of something else.
Example Question #3 : Disassemble An Object Made Of Small Pieces Into A New Object
Once an object has been disassembled it's parts are no longer usable.
True
False
False
The statement presented in the question is false. You can take an object, break it into small pieces, and then put it back together to create something new. If you were to build a castle with blocks, you could knock it down and build something else instead. This is a simple example of making something new out of the pieces of something else.
Example Question #1 : Disassemble An Object Made Of Small Pieces Into A New Object
What does the term disassemble mean? Example: I need to disassemble the tower I made of blocks so I can make a rocket ship instead.
Take something apart
Take a photo of something
Cook something delicious
Kick with a strong force
Take something apart
The term disassemble means to take something apart. In this case, the child is taking apart a tower that has already been built to make something new. Objects can be disassembled, and their parts use for other projects.
Example Question #13 : Creation Of New Objects From Existing Objects
Which of these photos shows something made of smaller pieces that have been put together?
All of the answer choices are correct
All of the answer choices are correct
All of these photos show smaller pieces put together to make something new or larger. Bricks stacked to build a wall, blocks put together to create a tiger, and rings stacked into a cone are all pieces put together to make a whole.
