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.

Try the annual Engineering Challenge from Science Buddies! Open to all students worldwide, a new challenge and prizes are announced every January. Explore the current challenge as well as ones from past years!
Do you like your strawberry jelly with or without the seeds? Are you glad to have a seed-free watermelon, or do you enjoy spitting the seeds into the garden? You might not like to find seeds in your fruit, but fruit is the plant's way of dispersing seeds to make new plants. How many seeds can be dispersed for each type of fruit? As they say, in one end and out the other!

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.
Have you ever been swimming at the beach and gotten some water in your mouth by mistake? Then you know that the ocean is very salty. But what about other bodies of water? How much salt do they have compared to the ocean?
Have you ever seen a river from far above? It is fascinating how they carve their way through the landscape. But what makes the water in a river flow? Where does a river start and end? And why is it that rivers usually have lots of turns or bends and almost never flow straight? In this science project, you will make river models using aluminum foil and water to explore how water flow inside a river changes based on its shape.
A tried and true balloon activity is to rub a balloon on your head to make your hair stand up. How does the rubbing build up static electricity? Do this experiment to see if the number of rubs makes a difference.
Fresh strawberries and summer just go together. Walking through the local farmers' market on a warm day, the bright, red strawberries call out to you, beckoning you to buy them and take them home. The next day, as you get ready to savor the delicious berries, you notice that yesterday's juicy, red strawberries are now covered in...eewwww, mold! In this cooking and food science fair project, you will investigate thermotherapy and whether this technique can preserve strawberries and prevent mold…
Carbonated bevarages are quite popular in the United States (despite the health risks of drinking too much of the sugary ones). Many people love their bubbly, fizzy flavors. But how do the bubbles, fizz, and taste get into the water? In this cooking and food science project, you will work with baking soda, citric acid, and sweetener to create a your own soda pop. Once you develop your recipe, try it out on your friends and family. Who knows? You might create the next soda pop sensation!
While looking at a package of dry yeast it is hard to believe that the package has organisms in it that are alive. But add the right ingredients and presto, the mixture becomes a bubbly, oozing, mess of life! What are the right ingredients? What does that yeast need to become active? Do this science project and figure it out for yourself!
The world's oceans are home to the most strange and amazing creatures. What do scientists know about these deep-sea animals and how can they study them easily? One way to learn about these animals in their homes is to use underwater robots. Underwater robots can record data that would be difficult for humans to gather. But what are robots and how are they made? In this robotics engineering project, you will discover what makes up a simple robot and build and test your own underwater robot.
Do you wash your hands? You should— it's the best way to prevent the spread of germs. But germs can be tricky; they find nooks and crannies to hide in, so it takes good hand-washing technique to get rid of them. In this science project, you'll investigate which parts of the hand are the most difficult to wash germs off of.
Have you ever enjoyed eating a tasty sweet potato? They can be served as yummy mashed sweet potatoes with melted butter, turned into golden-brown sweet potato fries, or prepared in many other scrumptious ways. Did you know that you can make a sweet potato grow into a sweet potato plant, and grow several sweet potatoes this way? In this science project, you will grow your own sweet potato plants and investigate what part of the sweet potatoes is needed to grow the plants.
