TermDefinition
conclusion a summary and interpretation of results that explains how and why the outcome occurred
conduction the transfer of thermal energy between objects through direct contact
convection transfer of thermal energy within a fluid due to temperature differences
convection current a type of air current that develops as cooler and warmer particles move in a cycle
dense less compact
dependent variable the variable on the y-axis/output and is the effect or change you want to observe
energy transfer occurs when matter with higher kinetic or thermal energy interacts with matter that is lower in energy; energy moves from high to low
heat energy transferred within a substance or from one substance to another; always flows from a warmer area to a cooler area
independent variable the variable on the x-axis/input and cause changes
insulator a material that is not good at conducting thermal energy transfer
kinetic energy the energy of motion
mass the amount of space matter takes up
modifications changes made
potential energy energy from position; solid particles have lower potential energy since they are close together; liquids and gases have higher potential energy since they have more space
radiate distribute heat to surroundings
radiation the transfer of energy in the form of waves through matter or through empty space
reasoning an explanation of the data and how that supports your conclusion
temperature a measure of the average kinetic energy of the particles in an object due to their random motions
thermal energy the total energy of the particles of a substance

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
