Misc
100
This state of matter has a definite shape and a definate volume
Solid!
100
When ice cream melts on a hot day, it changes from a solid to this.
liquid?
100
We mixed cornstarch and water to make this weird substance that acts like both a solid and a liquid.
oobleck
100
Anything that has mass and takes up space is called this.
Matter

When the class shrinks and lands in the bowl, they watch flour being stirred. Stirring is this kind of change.
physical change
200
This state of matter takes the shape of its container but has a definite volume
Liquid
200
This change of state happens when liquid water turns into water vapour.
evaporation
200
In this experiment, we put baking soda and vinegar together to inflate a balloon, the gas produced was this.
carbon dioxide
200
These tiny building dots make up all matter, too small to see with the naked eye.
particles
200
How did they escape the oven in The Magic Schoolbus?
Baking soda and Vinegar chemical reaction
300
This state of matter has no deifinite shape and no definite volume
Gas
300
When you see water droplets on a cold glass, this change of state is happening.
condensation
300
When we worked with clay, we changed its shape/colour without changing what it's made of. This type of change is called this.
physical change
300
When ice melts, this is a?
Physical Change
300
TRUE or FALSE: Oobleck is a pure liquid because it can flow.
False, oobleck is a non-Newtonian fluid; it behaves like both a solid and a liquid.
400
In this state, particles are packed tightly together and barely move
Solid
400
The temperature at which a solid becomes a liquid is called this.
melting point
400
Oobleck is weird because it doesn't act like a normal liquid, scientists call substances like this by this term.
non-Newtonian fluid
400
When matter changes from one state to another, like melting or freezing, this word describes what happened to it.
change of state
400
The class sees bubbles in the dough before baking when air gets trapped from mixing. This is not a new substance forming.
physical change
500
This term is used to describe the amount of space that matter takes up
Volume
500
When water vapour in the air cools and turns back into liquid, this is the process and it's also how clouds and rain form.
condensation
500
When baking soda and vinegar mixed, it created carbon dioxide. What type of change was this?
Chemical Change
500
When liquid water is heated enough, it bubbles and turns to steam. This specific type of evaporation has its own name.
boiling
