Grade 6 Quick Quiz: Earth and Space Science Review

📚 Science 🎓 Grade 6

Learning Objectives

  • Identify the Sun as the largest and most massive object in the solar system.

  • Match summer and winter solstices to approximate dates and identify longest and shortest days (Northern Hemisphere).

  • Explain why the Milky Way appears as a milky band in a dark sky.

  • Compute the probability of two independent events by multiplying their probabilities.

  • Convert a simple measurement from feet to meters using a provided conversion factor.

Question 1

Solar System Scale: Sun vs Planets (Not to scale)
A simple size comparison diagram: a very large circle labeled Sun, and much smaller circles labeled Jupiter and Earth....
Question 1

Which object is the largest and most massive object in our solar system, and the reason it is called the "solar" system? (See Diagram C-002 if helpful.)

Question 2

Earth is tilted as it orbits the Sun. Because of this tilt, the Sun appears higher or lower in the sky at different times of year. A solstice happens when Earth reaches a point in its orbit where one hemisphere is tilted most toward the Sun (summer solstice) or most away from the Sun (winter solstice). In the Northern Hemisphere, the summer solstice is the longest day of the year (most daylight), and the winter solstice is the shortest day of the year (least daylight). These happen around late June and late December.

Solstice Tilt Diagram (Northern Hemisphere)
A simple diagram showing the Sun in the center and Earth at two positions: June with the Northern Hemisphere tilted toward the Sun (longest day) and December with the Northern Hemisphere tilted away (...
Question 2

In the Northern Hemisphere, which choice correctly matches the solstices to their approximate dates AND identifies the longest and shortest days?

Reference: Earth is tilted as it orbits the Sun. Because of this tilt, the Sun appears higher or lower in the sky at different times of year. A solstice happens when Earth reaches a point in its orbit where one hemisphere is tilted most toward the Sun (summer solstice) or most away from the Sun (winter solstice). In the Northern Hemisphere, the summer solstice is the longest day of the year (most daylight), and the winter solstice is the shortest day of the year (least daylight). These happen around late June and late December. (See Diagram C-004 if helpful.)

Question 3

Why the Milky Way Looks Milky
A simple edge-on galaxy diagram: a thin disk with a brighter center and scattered dots labeled stars, with a hazy band labeled dust and gas that scatters starlight....
Question 3

On a dark night far from city lights, the Milky Way can look like a faint, milky band across the sky. Why does it have this "milky" appearance? (See Diagram C-005 if helpful.)

Question 4

Independent Probabilities Multiply
A diagram showing two boxes labeled Die 1 and Die 2, each with probability 1/6 for rolling a 1, and an arrow showing multiplication to 1/36....
Question 4

You roll two fair 6-sided dice. What is the probability of rolling a 1 on BOTH dice? (Hint: for independent events, multiply the probabilities. See Diagram C-006 if helpful.)

Question 5

Imperial to SI Quick Chart
A small table listing common conversions: 1 foot equals 0.3048 meter, 1 inch equals 2.54 centimeter, 1 yard equals 0.9144 meter, and 1 mile equals 1.609 kilometer....
Question 5

Use the conversion chart (also shown in Diagram C-007):
• 1 foot (ft) = 0.3048 meter (m)
• 1 inch (in) = 2.54 centimeter (cm)
• 1 yard (yd) = 0.9144 meter (m)
• 1 mile (mi) = 1.609 kilometer (km)

A classroom wall is 10 feet long. About how many meters long is it?
