States of Matter
Reviewing States of Matter
- heating - when matter gains thermal energy
- cooling - when matter loses thermal energy
- matter - a physical substance which occupies space and has mass
- property - an attribute or characteristic of something
- molecule - a group of atoms which are bonded together (chemistry)
- thermal energy - heat energy
- condensation - when a gas is converted to liquid due to cooling
- State of Matter- solid, liquid, gas, plasma
- occupy - to use a specific space
- predict - to say something that will happen in the future
- caused - to make something happen
- outcomes - the way something turns out
Characteristics of Solids, Liquids, and Gases:
How fast can you melt an ice cube in your hand?
Use the sentence stems, " I believe my ice cube will melt in the fastest time because I will __." and, "I predict it will take __ minutes/seconds to melt the ice cube."
After you have written your prediction in your science notebook, discuss it with your partners using the same sentence stems.
When you have finished predicting and discussing, please put your finger on your nose.
- Listen to instructions on the use of a stopwatch.
- Create a table for gathering data. (Your teacher will help you with this.) Every person is responsible for recording their own data.
- Take turns melting an ice cube in your hand (over the cup) while a member of your team times it.
- Record each person's time in your science journal.
- Reflect: Who melted the ice cube the fastest? How long did it take? How did they do it? Why do you think it worked?
- What patterns did you observe as matter changed from one state to another?
- What do the changes imply about the molecules in the water?
- What is your evidence?
