Unit 2 Lessons 1-3

Which of the following are the important parts of the cup system?

• Walls

• Layers

• Water

• All of these!

Which of the following is not an important part of the cup system?

• Air outside

• Air inside

• desk

• Lid

What is the purpose of features in fancy cups like material, double walls, lids or straws?

• To improve the flavor of the drink

• To increase or decrease the temperature of the liquids

• They don't have a purpose

• To help maintain (or keep the same) temperature of the liquids

What is an independent variable?

• An independent variable is the variable that is changed or controlled in a scientific experiment.
• A variable that is not related to the experiment.
• A variable that remains constant throughout the experiment.
• A variable that is measured in response to changes.

What is a dependent variable?

• A dependent variable is the variable that remains constant in an experiment.
• A dependent variable is the variable that is manipulated by the researcher.
• A dependent variable is the initial condition set before an experiment.
• A dependent variable is the variable that is measured in an experiment, which is affected by changes in the independent variable.

What is a constant in an experiment?

• A constant is the main focus of the experiment.
• A constant in an experiment is a factor that does not change.
• A constant is a measurement taken at the end of the experiment.
• A constant is a variable that changes during the experiment.

Which of the following would be an appropriate hypothesis for the lid experiment we did yesterday?

• If the cup had metal material, then the water would cool down, as measured by the liquid on the outside of the cup.

• If the cup had a lid, then the water temperature would stay hot, as measured by the temperature.

• I think the lid will come off the cup.

• If the cup is double layered then it will be good.

In an experiment where the cup had a lid, the initial temperature of the liquid was 5 degrees. The final temperature after 20 minutes was 10 degrees. What is the temperature change?

• 2

• 5

• -5

• 3

In an experiment where we tested a cup with a lid and a cup without a lid, the cup with the lid had a 5 degree temperature change. The cup without the lid had a temperature change of 10 degrees. Which of the following claims best fits the data?

• Covering a cup increases heat loss.
• The cup without a lid retains heat better.
• Both cups experienced the same temperature change.
• Covering a cup decreases heat loss.

What is the definition of kinetic energy?

• Kinetic energy is the energy stored in an object at rest.
• Kinetic energy is the energy associated with an object's temperature.
• Kinetic energy is the energy released during a chemical reaction.
• Kinetic energy is the energy of an object in motion.
