IDENTIFY
The three states of matter.
What is solids, liquids, and gases?
Puddle of water freezes in the winter turning into a ice.
What is freezing?
A rollercoaster moves downhill, gaining speed.
What is the kinetic energy increases?
What is your body's thermal energy will increase due to movement and radiation?
melting / solids
What is when a solid melts, it becomes a liquid?
Volume
What is the amount of space an object takes up?
Mrs. Odom boiled water and steam was seen coming off the top. This is the two states of matter that was observed in this experiment.
What is gas/liquid?
A car at a stop sign begins to drive.
What is the potential energy decreases/kinetic energy increases?
You drop a tennis ball from the top of the bleachers in the gym and it starts to speed up as it falls. Conclude what is happening to the kinetic energy.
What is the kinetic energy is increasing due to the falling down motion?
Convection / Noodles
What is cooking noodles is convection due to water being used?
A conductor
What is material that take in heat energy/get hot if left outside?
If a liquid cools down enough to freeze and predict the particles' (atoms') reaction and state of matter.
What is the particles will slow down and lose space, turning into a solid.
As a ball is thrown in the air and hits the floor.
What is the kinetic energy decreases/ potential energy increases.
After a basketball game, the player notices that the ball is warm at touch. Conclude what happened to the thermal energy and the transfer present.
What is the thermal energy increased and conduction was present due to him touching the ball?
Basketball / Insulator
What is the basketball is an insulator because it is made of rubber which does not take in heat easily?
Melting
What is the reaction when temperature of a substance changes it from a solid to a liquid?
Heat is applied to butter in a hot pan, causing it to melt quickly. Explain the changes of matter and thermal energy.
What is the butter will turn into a liquid due to an increase in thermal energy.
A metal spoon is placed in a freezer for an hour.
What is the thermal energy decreases?
Two sticks are rubbed together which starts a fire, eventually creating smoke. Conclude the states of matter present and what happens to the thermal energy.
What is a solid created a gas which also increased the thermal energy?
What is a liquid turns into a gas due to the thermal energy increasing?
Look at the pictures on the white board.
Identify the space and movement of each state of matter.
Solids: no space, vibration
Liquids: a little space, flows back and forth
Gases: a lot of space, freely
A puddle of water disappears after a sunny afternoon. Give the vocabulary term and explain the process.
What is vaporization/evaporation when thermal energy turns a liquid into a gas?
Rubbing your hands together. (TWO)
What is the thermal energy increases and kinetic energy increases?
A quarter gets colder while sitting outside. What can you conclude about the thermal energy and the transfer present.
What is the thermal energy decreased and radiation is present?
Kinetic Energy / Thermal Energy / Microwave.
What is the microwave moves the food around, increasing the kinetic energy, which also increases the thermal energy, warming up the food ?
