Science Buddies'
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.
The author of this project hypothesized that movies often disappoint readers because book-based movies tend to "dumb down" the works on which they are based (Fuhrman, 2002). Naturally, selective compression is necessary when telling a story as a movie, or no one would sit through it. (Hey, maybe there's an idea for a different experiment!) Selective compression is not necessarily the same, however, as simplification. There are ways to objectively measure the complexity of written language…

Have you ever wondered why golf balls have a pattern of dimples on their surface? The dimples are important for determining how air flows around the ball when it is in flight. The dimple pattern, combined with the spin imparted to the ball when hit by the club, greatly influence the ball's flight path. For example, backspin generates lift, prolonging flight. When the ball is not hit squarely with the club, varying degrees of sidespin are imparted to the ball. A clockwise sidespin (viewed from…

Many people are surprised to learn that the season's we experience—winter, spring, summer and fall—have nothing to do with the distance of Earth from the Sun. In this science fair project, you will investigate how the temperature on Earth actually depends on the tilt of Earth's axis of rotation.

Time Required
Short (2-5 days)
Prerequisites
None
Material Availability
You will need a couple of specialty items: a globe of Earth and a heat lamp. Light from the sun can be used if a heat lamp is not available.
Cost
Average ($50 - $100)
Safety
Minor injury is possible, so be careful when using the heat lamp.
Have you ever known someone who had a bad reaction to a prescription drug? Although pharmaceutical companies test new
drugs on a large number of people to make sure the drug works the way it is supposed to, often a small percentage of
people respond differently to the drug. A person's genetics plays a large role in determining his or her response to a
given drug.
Our genes are made up of hundreds to millions of nucleotides of DNA (deoxyribonucleic acid),
the genetic code. If just a…

After 23andMe receives your sample, your results should be ready in 6-8 weeks. Alternatively, you can do
this science project using a readily available free demo account on 23andMe.
Think of a way to launch the puck with a reproducible force, and examine the effect of launching the puck in different orientations on the distance it travels. For more information on the physics, see Haché, 2002.

The human body has an impressive ability to heal itself after injury, but humans have nothing on planaria. Planaria have an amazing ability to regenerate. An entire animal can regenerate from just a fraction of the body! This project investigates the effect of magnetic field intensity on planarian regeneration.
