Science Fair: 6th Grade Questions About Space And Motion - Quiz

One of the single most intriguing topics in all of science is without question space, motion and the universe we live in. What do you know about the solar system we inhabit? Let’s find out!

Questions and Answers

1.

What is the closest planet to the Sun in our solar system?
- A.
  
  Venus
- B.
  
  Mercury
- C.
  
  Mars
- D.
  
  Earth
Correct Answer
B. Mercury

Explanation
Mercury is the closest planet to the Sun in our solar system. It orbits the Sun at an average distance of about 36 million miles, which is much closer than any other planet. Its proximity to the Sun means that it has a very short year, completing one orbit in just 88 Earth days. Additionally, Mercury experiences extreme temperature variations, with surface temperatures reaching up to 800 degrees Fahrenheit during the day and dropping to -290 degrees Fahrenheit at night.

What is the hottest planet in our solar system?
- A.
  
  Venus
- B.
  
  Mars
- C.
  
  Mercury
- D.
  
  Saturn
Correct Answer
A. Venus

Explanation
Venus is the hottest planet in our solar system because it has a thick atmosphere made up mostly of carbon dioxide, which creates a greenhouse effect. This traps heat and causes the surface temperature to reach extremely high levels, averaging around 900 degrees Fahrenheit (475 degrees Celsius). Despite being further from the Sun than Mercury, Venus has a much higher surface temperature due to its dense atmosphere. Mars and Saturn, on the other hand, have much colder temperatures compared to Venus.

What is the formula for speed?
- A.
  
  Time/distance
- B.
  
  Time*distance
- C.
  
  Distance/time
- D.
  
  Force/weight
Correct Answer
C. Distance/time

Explanation
The formula for speed is distance divided by time. This formula calculates how fast an object is moving by dividing the distance it has traveled by the time it took to travel that distance. By dividing the distance by the time, we can determine the rate at which the object is covering the distance, giving us the speed.

What is the unit for forces?
- A.
  
  Pounds
- B.
  
  Newtons
- C.
  
  Ounces
- D.
  
  Centimeters
Correct Answer
B. Newtons

Explanation
The unit for forces is newtons. Newton is the standard unit of force in the International System of Units (SI). It is named after Sir Isaac Newton and is defined as the amount of force required to accelerate a one-kilogram mass by one meter per second squared. Other options like pounds, ounces, and centimeters are not standard units for measuring forces.
