Eighth Grade Science Projects (689 results)

Science Buddies' eighth grade science projects are the perfect way for eighth grade students to have fun exploring science, technology, engineering, and math (STEM). Our eighth grade projects are written and tested by scientists and are specifically created for use by students in the eighth 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, eighth 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.

Rainbow Fire Log in to add favorite More Menu Read More Show Others Like This Project Kit Available Science Fair Project Idea Astronomers can figure out what distant stars are made of (in other words, their atomic composition) by measuring what type of light is emitted by the star. In this science project, you can do something similar by observing the color of flames when various chemicals are burned. Read more Solar-Powered Water Desalination Log in to add favorite More Menu Read More Show Others Like This Project Kit Available Science Fair Project Idea How can seawater from the oceans be turned into fresh water that is suitable for people to drink? Through a process called solar desalination! In this science project, you will make a solar desalination apparatus using readily available materials, and a power source that is free. How much water can the device produce, and is it still salty at all? What factors affect how effectively saltwater is turned into fresh water? Read more Candy Chromatography: What Makes Those Colors? Log in to add favorite More Menu Read More Show Others Like This Project Kit Available Science Fair Project Idea Quick, what is your favorite color of M&Ms® candy? Do you want to know what dyes were used to make that color? Check out this science project to find out how you can do some scientific detective work to find out for yourself. Read more Now You're Cooking! Building a Simple Solar Oven Log in to add favorite More Menu Read More Show Others Like This Science Fair Project Idea 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. Read more The Physics of Artificial Gravity Log in to add favorite More Menu Read More Show Others Like This Science Fair Project Idea How can we make space stations with artificial gravity a reality? In this science project, you will explore the physics of creating artificial gravity with circular motion. Read more Basketball Physics: Where Does a Bouncing Ball's Energy Go? Log in to add favorite More Menu Read More Show Others Like This Science Fair Project Idea Have you ever noticed that when you drop a basketball, its bounce does not reach the height you dropped it from? Why is that? When a basketball bounces, such as on a basketball court, its bounce actually loses momentum by transferring energy elsewhere. This means that to dribble the basketball, players must continually replace the transferred energy by pushing down on the ball. But what happens to the "lost" energy? As we know from physics, energy is not really lost, it just changes form. One… Read more Use Floating Leaf Disks to Study Photosynthesis Log in to add favorite More Menu Read More Show Others Like This Science Fair Project Idea Have you ever seen a (non-carnivorous) plant eat? Probably not! Plants do not get the energy they need from food, but from the sunlight! In a process called photosynthesis, plants convert light energy, water, and carbon dioxide into oxygen and sugar. They can then use the sugar as an energy source to fuel their growth. Scientists have found an easy way to measure the rate of photosynthesis in plants. The procedure is called the floating leaf disk assay. In this plant biology project, you can… Read more Effect of Friction on Objects in Motion Log in to add favorite More Menu Read More Show Others Like This Science Fair Project Idea The funny thing about friction is that you couldn't get anywhere without it, yet it still acts to slow you down as you're getting there. Here is an easy project to measure the effects of friction. Read more Measuring the Amount of Acid in Vinegar by Titration with an Indicator Solution Log in to add favorite More Menu Read More Show Others Like This Science Fair Project Idea 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… Read more Build a Gauss Rifle! Log in to add favorite More Menu Read More Show Others Like This Project Kit Available Science Fair Project Idea What can you do with magnets and ball bearings that makes a lot of noise? Why, build a magnetic linear accelerator, called a Gauss rifle, of course! Now, this magnetic accelerator is not a weapon, but a way for you to learn a lot more about physics concepts, like momentum. In this physics science project, you will investigate how far a ball bearing launched by a Gauss rifle will fly, depending on how many magnetic acceleration stages are in the setup and the ball bearing's initial velocity.… Read more < 1 2 3 4 5 ... 69 >
