Scientific Method
A prediction of an experiment is called what?
A hypothesis.
What do the particles look like in an ice cube?
They are orderly, there is not much space between them and they are vibrating.
What happens when you add heat to a solid?
It reaches its melting point and will melt into a liquid.
What happens when you add cold temperatures to a gas?
Condensation. The gas turns into a liquid.
Ice turns into a liquid. What process occurred?
Melting.
What type of answer do we ask when we identify a problem?
A yes or no question.
My particles are close together, orderly and vibrating. What am I?
A solid.
What is a melting point?
A temperature when a solid turns into a liquid.
What is a freezing point?
A temperature when a liquid turns into a solid.
My particles look like jumping around and waving your arms. What am I?
A gas.
What does test your hypothesis mean?
To conduct your experiment.
My particles are moving very fast and there is lots of space between us. What am I?
A gas.
What happens when you add heat to a liquid?
The liquid will reach its' boiling point and evaporate into a gas.
What happens when you add cold temperatures to a liquid?
The liquid cools, then reaches its freezing point and turns into a solid.
When you put milk in the fridge. What process is happening to the milk?
An explanation of an observation.
What is an inference?
My particles are further apart and moving around. What am I?
A liquid.
What is a boiling point?
A temperature when a liquid evaporates into a gas.
What is sublimation?
When a solid skips a step and turns into a gas.
True or False. The physical changes of matter are reversible?
True. Freezing is the opposite of Melting. Evaporation is the opposite of Condensation.
What is the design of the experiment?
The steps needed to complete the experiment.
What do particles look like in water?
Loose, flowing, more space between them, moving faster than a solid.
What happens when you add heat to a gas?
The gas it expands.
What is the process called when hot steam fogs up a cold mirror?
Condensation, as the hot steam condenses and turns back into a liquid.
What is the boiling point of water?
100*C
