Ninth Grade, Astronomy Science Projects (24 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.

Star light, Star bright: How Does Light Intensity Change with Distance?
Science Fair Project Idea
Scientific Method
Have you ever looked up at the stars at night and wondered how fast they were moving or how far away they were? By studying how the brightness of a star changes with distance, you can answer those questions. In this astronomy science project, you'll create a model of starlight and use a sensor app with your smartphone to discover the key relationship between brightness and distance. Read more
Correlation of Coronal Mass Ejections with the Solar Sunspot Cycle
Science Fair Project Idea
Scientific Method
Scientists have known for hundreds of years that sunspot activity waxes and wanes over a cycle that lasts approximately 11 years. In the 1970's, scientists discovered that the sun periodically blasts electrified gases into space, in huge outbursts called 'coronal mass ejections,' or CMEs. This project asks the question: do CMEs follow the solar sunspot cycle? Read more
X-Ray Vision: Seeing Into Space
Science Fair Project Idea
Scientific Method
Have you ever seen amazing, colored images of objects in space, like stars or even entire galaxies? Some of these images were originally taken with forms of radiation that the human eye cannot actually see, like x-rays. In order to create the beautiful pictures you see in the news or online, scientists have to use an image-editing program to add color to them. In this astronomy science project, you will use raw x-ray data from NASA's Chandra X-ray Observatory telescope to create amazing… Read more
Finding the Center of the Milky Way Galaxy Using Globular Star Clusters
Science Fair Project Idea
Scientific Method
The Milky Way is the edgewise view of our home galaxy, a disk made up of billions of stars. The Sun resides on one of the spiral arms of the disk, 30,000 light-years from the thick hub of the galaxy. The actual center, with a black hole 3-4 million times the Sun's mass, is hidden by dust clouds in space. In this astronomy science fair project, you will use astronomical data to locate the center of this galaxy. Read more
Can AI Classify Stars?
Science Fair Project Idea
Engineering Design Process
Understanding the different types of celestial objects in our galaxy is important for astronomers. It helps them study how these objects form and evolve, map the night sky, understand the structure of the Milky Way and other galaxies, and identify celestial bodies that might host habitable environments. In this project, you will create a boosted tree model to classify celestial objects based on their spectral characteristics. Read more
A Model of Gravity in Our Solar System
Science Fair Project Idea
Scientific Method
Why do the planets orbit the sun without flying off into space? Do they move in perfect circles or do their orbits take a different shape? And how could you possibly do a science project about any of this—you can't do an experiment with the planets! However, you can build a model of our solar system that demonstrates the concept of gravity, using balls of different sizes to represent the sun and planets. Watch the summary video for an excellent introduction to the model. Think about how… Read more
Asteroid Mining: Gold Rush in Space?
Science Fair Project Idea
Scientific Method
You've heard of gold mining and coal mining, but think outside the box...or the planet...what about asteroid mining? Scientists, engineers, and business people believe asteroid mining is feasible, and they are in the beginning stages of long-term plans to mine asteroids for valuable resources during space missions. You don't want to miss out on all the fun; in this science project, you will come up with your own scientific plan for an asteroid mining company. We will help get you started by… Read more
Similar Triangles: Using Parallax to Measure Distance
Science Fair Project Idea
Scientific Method
Want to stretch your imagination? One good way is to try to imagine how far it is to a distant star. How much farther away is it than the moon is from the earth? How much farther away than the earth is from the sun? How long would it take to get there? In this project, you'll learn one way of measuring the distance without leaving Earth. Read more
Space Radiation Protection
Science Fair Project Idea
Engineering Design Process
The radiation sources recommended in this experiment are low-dose radioactive sources and do not require a license to purchase; they are safe to work with as long as these common-sense safety tips are followed: Wear disposable gloves when handling any radioactive source. Never rub your eyes or mouth while you are handling the radioactive source. NEVER swallow any radioactive source and use protective glasses when bringing a source within a few inches of… Read more
Analyzing Impact Craters on Mercury
Science Fair Project Idea
Scientific Method
Have you ever wanted to analyze data from a NASA spacecraft? In this science project you will use data from NASA's MESSENGER mission to measure the diameter and calculate the depth of impact craters on Mercury. You will then analyze that data for relationships between a crater's depth and diameter. This is your chance to perform a science project as a NASA researcher would! Read more
