Understand that Earth moves in two ways: it rotates (spins) on its axis once every 24 hours causing day and night, and it orbits (travels around) the Sun once every 365 days, which is one year
A first look
This shelf is still being planted — the questions are being written and checked. Come back soon. A Skill needs at least 5 checked questions before it opens here.
Question 1 of 3
A space scientist says a planet makes two complete trips around its sun in 730 days. How many days does it take for one complete trip around the sun?
Question 2 of 3
If you spin a globe in front of a lamp that stands for the Sun, what happens to the spot that was lit by the lamp after the globe makes half a turn?
Question 3 of 3
You have a small ball that stands for Earth and a lamp that stands for the Sun. A tiny sticker marks the city of River Town on the side of the ball that is facing away from the lamp (so it is in darkness). You spin the ball at a steady speed so that it makes one complete turn in 24 minutes. After how many minutes will River Town first be lit by the lamp?
