The Design Process
The very first step of the design process is to define this.
What is the problem
This is a state of matter with a definite shape and a definite volume, like a solid surfboard
What is Solid state
The measure of how much "stuff" is in an object.
What is the mass
When ice turns into water, it's called this process.
What is melting
When you see clouds form in the sky, it's an example of this process on a giant scale
What is condensation
: After defining the problem, the next step is to come up with a bunch of possible ideas for a solution.
What is brainstorming
A liquid has a definite volume, but it takes the shape of this.
What is container
This characteristic of an object describes what it looks like, feels like, or is made of, and it can be observed without changing the substance.
What is property
This is the temperature at which a solid substance turns into a liquid.
What is melting point
This is what must happen to the temperature of a gas to make it condense into a liquid.
What is gets lower or cooler
: A model of your design that you can test to see if it works
What is a prototype
A balloon that you blow up is full of this state of matter, which has no definite shape or volume.
What is gas
This is what you're measuring when you check how much space a box or a bottle of water takes up.
What is volume
This kind of energy is needed to turn a solid into a liquid.
What is heat or thermal energy
Materials like rubber, plastic, and wood are examples of this, because they do not let heat or electricity pass through them easily.
What is an insulator
After testing your prototype, you analyze the results and do this to your design.
What is improve it
This is what happens to a liquid's particles when you heat it up and it turns into a gas.
What is spread out and move faster.
This is a solid's ability to be scratched or to scratch another object
What is hardness
This is what happens to the particles of a solid when it starts to melt
What is they move faster and break away from their fixed positions?
When a substance dissolves in a liquid, it's called this.
What is solubility
The design process is a cycle, meaning it repeats. This is what you must do after testing your prototype and making improvements
What is test the new design
The process of a gas turning into a liquid, like when steam becomes water droplets on a cold surface.
What is condensation
The measure of a liquid's thickness or resistance to flow
What is viscosity
When a crayon melts in the sun, it's a physical change because it's still a crayon, just in a different this.
What is a state of matter
To help a solid dissolve faster, you can do this to the liquid.
What is heat it up
