Record the compass deflection at a distance of 2 cm from the wire. What is the deflection in degrees?

• 10 degrees

• 15 degrees

• 20 degrees

• 25 degrees

Answer explanation

The compass deflection at 2 cm from the wire is influenced by the magnetic field generated by the current. At this distance, the deflection is measured to be 20 degrees, making it the correct choice.

• 10 degrees

• 15 degrees

• 20 degrees

• 25 degrees

Answer explanation

The compass deflection at 25 cm from the wire is influenced by the magnetic field generated by the current. At this distance, the deflection is measured to be 20 degrees, making it the correct choice.

Describe any patterns or trends in the data you observed:

• The data shows a consistent upward trend.

• The data fluctuates with no clear pattern.

• The data shows a consistent downward trend.

• The data remains constant over time.

Answer explanation

The correct choice indicates that the data fluctuates with no clear pattern, suggesting variability without a consistent direction, unlike the other options which imply trends or constancy.

What did you notice about their findings? Were there any patterns or trends they highlighted that you found insightful?

• Yes, there were noticeable patterns and trends.

• No, there were no significant patterns or trends.

• The findings were not clear enough to determine patterns.

• I did not review their findings.

Answer explanation

The correct choice highlights that there were noticeable patterns and trends in the findings, indicating valuable insights that can be drawn from the data analyzed.

Which of the following is a constructive suggestion for improving data collection or analysis?

• Increase sample size

• Ignore outliers

• Reduce data points

• Use outdated software

Answer explanation

Increasing the sample size enhances the reliability and validity of data collection and analysis, leading to more accurate results. The other options either compromise data quality or use ineffective methods.

• To explore the history of electricity.

• To learn about different types of magnets.

• To study the effects of static electricity.

Answer explanation

The objective of the 'Think-Pair-Share Worksheet: Electric Currents and Magnetic Fields' is to understand the relationship between electric currents and magnetic fields, making this the correct choice.

What did you observe happening to the compass needle when the current in the wire was increased?

• The compass needle deflected more.

• The compass needle deflected less.

• The compass needle did not move.

• The compass needle reversed direction.

Answer explanation

As the current in the wire increases, the magnetic field around the wire strengthens, causing the compass needle to deflect more. This demonstrates the relationship between electric current and magnetic fields.
