Bible Science Experiment: Globe shows why Summer Solstice is the Longest Day

This Bible science lesson demonstrates for kids why the sun will not set in Alaska for several days during summer solstice. This will also help them understand a little about heaven, which is lit by the light of God himself and never gets dark!


– Globe on a stand

– Flashlight


– Place the globe on a table. Most globes are tilted slightly, but allow for that tilt for now – don’t try to turn it straight up.

– Turn the globe so that North America is facing you and the students.

– Have a student shine the flashlight exactly at the equator.

– Tilt the globe purposefully now so that the North Pole is a closer to the center and the southern hemisphere is away from you.

– Have students notice where the light is now shining (mostly onto North America).

– Spin the globe slowly.

– Have students notice what continents the light is shining most brightly on.

– Have them notice what’s going on at the North Pole (the light shines on it constantly).

– Point out that if the flashlight were the sun, it shows how the sun doesn’t set on northern Alaska and the North Pole as long as the earth maintains that tilt (the days preceding and following the summer solstice).


The tipping of the globe shows what happens in real life. In summer, the northern hemisphere comes closest to the sun. The days get longer and the atmosphere warms. In winter, the southern hemisphere comes closest to the sun, and the days get longer for us u here, and the air gets colder.

The first day of summer, for us in the northern hemisphere, is known as the summer solstice. It is the longest day of the year because the sun reaches its most northern point in the sky at noon on that day. After this date, the northern hemisphere begins tipping away from the sun and the days start getting shorter.


Revelation 21:23 says this about the kingdom of God: “The city doesn’t need any sun or moon to give it light, because the glory of God gave it light, and the lamb was its lamp.” Someday we won’t need any sun because the light of God will be so bright! In the meantime, we will have lightness and darkness, just as we will have bright times and dark times in our lives.

God often leaves us with clues as to his nature in the earth’s nature. His ability to give Alaska and the North Pole constant light reminds us that someday we will have endless and constant light in the Kingdom of Heaven.
