Fourth Grade, Astronomy Projects, Lessons, Activities (19 results)

Astronomy is science that will challenge your imagination. How many stars in a galaxy? How many galaxies in the known universe? How many strange worlds are out there on other planets, orbiting other stars, and what are they like? Is there life on planets besides Earth? The distances are mind-boggling; the numbers are immense.

Did you know that there are more planets than stars in our galaxy? All of these planets circle around a star, but only eight of them—Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune—circle around the Sun—the star in our solar system. This activity explores the relative size of these eight planets. Is one bigger than the others, or are they all about the same size? Read more
The Moon and Tides
Science Fair Project Idea
Scientific Method
Have you ever wondered what causes the tides in Earth's oceans? In this astronomy project, you will discover the answer for yourself! You will investigate how the Sun and Moon control tides in Earth's oceans. Read more

Did you know that the Voyager 2 spacecraft took 12 years to travel from Earth to Neptune, the furthest planet in the solar system? This sounds like a really long time! Maybe not that long if you consider what distance the spacecraft had to travel to get from Earth to Neptune. In this activity, you will make a model of the planets in the solar system and specifically model their distances to scale. Will it explain why the Voyager 2 took so long? Try it and see! Read more
The Reasons for the Seasons
Science Fair Project Idea
Scientific Method
Do you live someplace where you get to experience the full glory of all four seasons? If so, you know well the heady blossoms and dramatic skies of spring; the long, sun-drenched days of summer; the trees shaking in crimson and gold in fall; and the sparkling, brittle snows of winter. But you might not know why we have these seasons, over and over again, in a cycle as predictable as the rising and setting of the Sun. The reasons for the seasons are surprising and have to do with Earth's tilt… Read more

What would it be like if you could see the planets of our solar system orbiting the Sun all at once? What about the moons orbiting the planets? Learn how to make your own simple demonstration of gravity and planetary orbits in this fun activity. Read more
A Puzzling Parallax
Science Fair Project Idea
Scientific Method
Do you enjoy going stargazing? In a good location on a clear night, you can see a huge number of stars twinkling in the night's sky. Have you ever wondered how far those stars are from us? Ancient astronomers actually discovered a way figure this out, measuring the distance from Earth to faraway stars. How did they do it without modern technologies? In this astronomy science project you will find out by exploring the link between the distance of an object and perspective (also known as… Read more

Changing Constellations
Science Fair Project Idea
Scientific Method
Do you like to look up into the night sky? There are so many stars, it can be mind boggling! Some ancient people marked time by the changes in star patterns. We still use changes in constellation patterns to mark astronomical time. Do constellations change more in one hour, one day, one month, or one year? Read more
