Multiple Choice

The Sun sends out tons of energy into space, but Earth only gets a small part of it—and that’s still enough to help keep our atmosphere stable. How do you think that energy travels all the way from the Sun to Earth? What makes it possible?

• conduction

• convection

• radiation

• reflection

Multiple Choice

Why might repeating the experiment help you figure out what's really going on?

• To prove replication by other scientists.

• To eliminate the need for controls.

• To increase the wave frequency.

• To improve reliability of results.

Multiple Choice

Why do you think doing it over and over again is important? What does it show about your experiment?

• Replication - repeated by different investigators.

• Repetition - multiple trials by one investigator.

• Refraction - wave bending through mediums.

• Reflection - wave bouncing back

Multiple Choice

Which of these is most likely described in this scenario?

• Repetition

• Replication

• Error analysis

• Equipment check

Multiple Choice

Based on the evidence from this experiment, which material is the best insulator?

• Plastic

• Stainless steel

• Silver

• Wood

Multiple Choice

What type of energy does the slinky have when it is sitting on the steps not moving?

• It has kinetic energy.

• It has potential energy.

• It has both kinetic and potential energy.

• It has neither potential nor kinetic energy.

Multiple Choice

On a cold day, Rick puts a hot cup of coffee down on a picnic table. Which of the following correctly describes what happens next?

• The temperature of the picnic table decreases as it transfers cold to the cup.

• The picnic table transfers its cold temperature to the coffee cup making the coffee colder.

• The coffee cup remains the same temperature as the temperature of the table increases.

• The heat from the coffee cup is transferred to the picnic table and the two surfaces reach a temperature equilibrium.

Multiple Choice

Based on the evidence in the picture, at which point does the pendulum weight have the greatest amount of kinetic energy?

• Position 1

• Position 2

• Position 3

• The kinetic energy does not change.

Multiple Choice

Which statement accurately describes the transformation of energy that occurred when Saul turned on the mixer?

• Electrical energy was converted to mechanical energy.

• Chemical energy was converted to mechanical energy.

• Electrical energy was converted to mechanical and sound energy.

• Chemical energy was converted to mechanical and thermal energy.

Multiple Choice

Why is the 2nd hill of a roller coaster always shorter than the 1st hill?

• Because the roller coaster gains extra potential energy at the top of the 1st hill.

• Because the track is designed incorrectly.

• Because the roller coaster loses some energy to heat and sound from friction and air resistance.

• Because the roller coaster creates new energy as it moves, making it go faster on smaller hills.

Multiple Choice

Suzanne is thirsty, so she asks her mom for a drink. Her mom brings her a cup of lemonade with ice in it. She notices that the lemonade increase in volume over time. Which of these describes what is happening?

• The lemonade is expanding over time.

• The ice is melting causing water to sit on top of the lemonade.

• The lemonade is surrounding the ice and moving on top of it causing it to look like there is more lemonade.

• The ice is melting and becoming water which mixes with the lemonade causing the volume of lemonade to increase.

Multiple Choice

Ms. Avery is camping with the Girl Scouts and used her Army experience to rub two sticks together to create a fire. Which form of energy below is not involved in this process?

• Thermal Energy

• Electrical Energy

• Mechanical Energy

• Chemical Energy

Multiple Choice

What is the scientific meaning of energy?

• Anything that has mass

• The ability to cause change

• Anything that cannot be seen

• The property of something to take up space

Multiple Choice

Which of the claims about why many experiments include several trials, instead of a single trial is correct?

• Repetition of trials makes data easier to analyze.

• Repetition of trials increases the accuracy of the results.

• Repetition of trials increases the sample size of the experiment.

• Repetition of trials lets the experimenter change the experimental procedure.

Multiple Choice

Which statement describes the difference between an independent and dependent variable?

• The dependent variable changes based on the independent variable.

• The dependent variable is the control, and the independent variable is the result.

• The dependent variable does not change, and the independent variable does not change.
