Elementary School Science Projects (658 results)

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

Science Fair Project Idea
In this engineering challenge, you will use limited materials to build a paper tower as tall as possible, but there's a twist! Your tower must also support a heavy weight at the top without collapsing. Follow the contest rules to try it out and enter the 2021 Fluor Engineering Challenge! Teachers, lesson plan versions of this challenge are also available. Read more

Science Fair Project Idea
Do you really catch more flies with honey than with vinegar? Do an experiment to find out! Watch the video above to learn how to make a simple homemade fly trap using a plastic bottle. Then, experiment to discover which bait attracts the most flies. You can try a variety of liquids, and you can also use solid bait like rotting food or meat, but you will need to add some water so the flies drown. A drop of soap can help break the surface tension of the water, making it easier for the flies to… Read more

Science Fair Project Idea
The human body is an impressive piece of machinery, and your hands are no exception. With some training, they can perform delicate and complex tasks like manipulating pens and tools to create art. At the same time, hands have the strength and durability to hold a person's own body weight up on steep rocks. Unfortunately, there is a rapidly growing demand for hand replacements. But fortunately, scientists have studied human anatomy and biology and created human-like hands used as artificial… Read more

Science Fair Project Idea
Do you want to build a solar-powered car? How about enter it in a competition and race it against other people's designs? If so, this is the project for you! These instructions will show you how to get started building a solar-powered car that you can enter in a science or engineering fair. No experience needed. If you want, you can even compete in the Junior Solar Sprint, a regional competition for solar-powered cars. Get more information about your regional competition. Are you a teacher?… Read more

Science Fair Project Idea
In this project, you'll learn how to isolate DNA from onion cells, separating it from other cellular components in a manner that still preserves its structure and sequence. In the end, you'll have enough DNA to see with the unaided eye, and you'll be able to spool it to demonstrate its strand-like structure. Read more

Science Fair Project Idea
Crystals come in all different shapes and sizes. However, the purest and cleanest crystals are usually also the ones that grow to be the largest in size. In this science fair project, you will compare the size and shape of crystals grown in three different temperature conditions: room temperature, in the refrigerator, and in an ice bath. With just water and borax, a household cleaning product, you can discover the best recrystallization method for growing large, pure crystals. Read more

Science Fair Project Idea
There are many different kinds of slime out there. Some slime is runny and liquid-like; other slime is thick and rubbery. Some slime glows in the dark, some is fluffy, and some is even magnetic! What set of properties makes the best slime? What kind of slime would you choose to make if you were selling slime as a toy in your own "slime shop"? In this project, you will experiment with different slime recipes and try to perfect one to make the best slime. Read more
