Second Grade Science Projects (243 results)
Science Buddies' second grade science projects are the perfect way for second grade students to have fun exploring science, technology, engineering, and math (STEM). Our second grade projects are written and tested by scientists and are specifically created for use by students in the second 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, second 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.
Let us help you find a science project that fits your interests, with our Topic Selection Wizard.

In this engineering challenge, you will build a car powered by nothing but a rubber band. The farther the car goes, and the fewer materials you use to build it, the higher your score. Enter your score in the 2024 Science Buddies Engineering Challenge for a chance to win prizes! Teachers, lesson plan versions of this challenge are also available.
"Swing me higher, Mommy, higher!" Kids love to ride the swings at the playground. The back-and-forth motion of a swing demonstrates the physics of a pendulum. In this experiment, you will investigate the factors that affect the speed and duration of a pendulum's swing, also called an oscillating motion. You can even use your phone and a sensor app to record your pendulum's movement and determine its period of oscillation.
Have you ever heard someone say that the moon is made of cheese? Even though the craters on the surface of the moon resemble holes in Swiss cheese, we know that this common myth is not true. Find out how craters are formed and why they are different sizes by doing this simple science project.
Vibrobots are fun little robots built from common household supplies, that are powered by vibrating motors. In this engineering project, you will design and built your own vibrobot. Would you rather have a robot that skitters quickly across a table or one that spins wildly in circles? How about a sumo-wrestling bot that can push others out of its way? The choice is up to you!
Do you ever wonder how markers are made? Where do all of those colors come from? Many of the colorful dyes we use come from plants. Could you create vibrant colored natural dyes? Could you turn these dyes into art supplies? You can! In this science project, become a scientist and engineer and make your own marker using homemade plant dye!
If you have ever been shot with a rubber band then you know it has energy in it, enough energy to smack you in the arm and cause a sting! But just how much energy does a rubber band have? In this experiment you will find out how the stretching of a rubber band affects the amount of energy that springs out of it.
Saturn is a unique planet because of the many beautiful rings surrounding it. How are all of those rings made? Why is each ring unique?
Have you ever eaten half an apple and saved the other half for later, only to find that, by time you were ready to eat it, the apple did not look as tasty anymore? It may have turned brown and shriveled, and, if left out long enough, it may have spoiled. Do you think you could have prevented the other half from spoiling, or made it spoil less, if you had stored it differently, such as in the refrigerator in a food wrapping? In this cooking and food science project, you will investigate which…
Kites have been a source of entertainment for centuries for kids from cultures around the world. In this science project you will have a chance to build your very own kite, a simple sled kite. Then you will use it to investigate how kites fly. Will you find out the best way to fly your kite?
A day at the beach is a wonderful way to spend time with your family and friends. You can swim, play games, and build sand castles. But have you ever thought about how all of that sand got there and wondered why the shoreline weaves in and out of the ocean? In this science project, you will investigate how ocean waves build beaches by making a model of the beach and shoreline. All you need is a tiny surfer and a beach volleyball court for your model, and you can imagine that you are in…
