4.       What is one difference between conduction and convection? _________________________________________ ___________________________________________________________________________________________
5.       Heat ALWAYS travels from ___________________ to _________________.
6.       Heat is also known as __________________ energy.
7.       Can heat travel from a snowflake to your tongue? ______________
8.       Can heat travel from your hand to an ice-cube? __________________
9.       What is an example of a time when heat goes from a hot object to a less hot object? ______________________ ___________________________________________________________________________________________
10.   The transfer of heat by the movement of air currents in Earth’s atmosphere is an example of:
a.       Conduction                        b. Convection                    c. Radiation                        d. Fusion
11.   The faster the particles of an object are moving, the _________________ the temperature of the object.
12.   The temperature of an object increases/decreases when its particles slow down.
13.   If two objects come in contact with each other and one is warmer than the other, what happens?
a.       Both objects get colder
b.      Both objects get warmer
c.       Energy is transferred from the colder object to the warmer object
d.      Energy is transferred from the warmer object to the colder object
