ninth grade science projects are the perfect way for
ninth grade students to have fun exploring science, technology, engineering, and math (STEM). Our
ninth grade projects are written and tested by scientists and are specifically created for use by students in the
ninth grade. Students can choose to follow the science experiment as written or put their own spin on the project.
For a personalized list of science projects,
ninth graders can use the Science Buddies Topic Selection Wizard.
The wizard asks students to respond to a series of simple statements and then uses their answers to recommend
age-appropriate projects that fit their interests.
There is strong interest in "going green," including using products that cause less environmental damage when they are disposed of. In this environmental sciences project, you will compare the toxicity of "green" and conventional liquid detergents using worms as test organisms.
Maple syrup on pancakes, ripe bananas, and soft drinks are all foods that are tasty to us
because of the sugar in them. But did you know there are different kinds of
sugar? One food can have multiple kinds of sugar in it, and our bodies actually process
the different types of sugars differently. In this science project, you will measure the
concentration of two sugars—glucose and sucrose—in different foods, and investigate how
sucrose is converted into glucose with the help…
Did you know that you can actually make objects come together by blowing air between them? Find out how wind changes air pressure to bring to objects together in this easy and fun science fair project!
Every day, no matter where you are, you will see people using their cell phones. People use their cell phones for
more than just making calls though. They use them for texting and searching the Internet, too. But some health groups
are concerned that using your cell phone too much can be hazardous to your health as it exposes your body to electromagnetic radiation. In this electricity and electronics
science project, you will investigate how much radiation your cell phone emits when used…
If you'd like to investigate the physics of amusement park rides, then this project is for you. You'll build a roller coaster track for marbles using foam pipe insulation and masking tape, and see how much the marble's potential energy at the beginning of the track is converted to kinetic energy at various points along the track.
Have you ever wondered why some foods taste really sour? Vinegar is one example that you might know from salad dressings or pickles. They taste pretty sour, right? There are many different types of vinegar that you can buy to use around the kitchen for cooking and pickling. The chemical compound that gives vinegar its tart taste and pungent smell is acetic acid. Do you think all the different vinegars contain the same amount of acetic acid? Are there some that are more sour than others? How…
Here is a project that uses direct solar power, gathering the sun's rays for heating/sterilizing water or cooking. It is a low-cost technology that seems to have everything going for it. Does it work? Can you find ways to improve it? Find out with this project.
Having a younger brother or sister can be a real chore. They can get into your things and mess up all your stuff. But have you ever thought that when younger siblings do this kind of thing, they are actually learning about the world around them and how to interact with their environment? Every day, a young child's brain is getting new information about his or her environment and developing ways to organize that information. Learning about and understanding this conduct is the study of human…
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 Google's Science Journal app with your smartphone or tablet to discover the key relationship between brightness and distance.
