Industry, Innovation and Infrastructure, Second Grade Science Projects (53 results)

The United Nations Sustainable Development Goals (UNSDGs) are a blueprint to achieve a better and more sustainable future for all.
These projects explore topics key to Industry, Innovation and Infrastructure: Build resilient infrastructure, promote sustainable industrialization and foster innovation.

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.

Build a Floating Maglev Train
Science Fair Project Idea
Scientific Method
How can you make a train without wheels? By using magnets! In this project you will build a magnetic levitation ("maglev" for short) train that floats above a magnetic track. How much weight can you add to the train before it sinks down and touches the track? Read more
How Far Will It Fly? Build & Test Paper Planes with Different Drag
Science Fair Project Idea
Scientific Method
Just one sheet of paper can lead to a whole lot of fun. How? Paper planes! All you have to know is how to fold and you can have a simple plane in a matter of minutes! But what design should you use to build the best plane? In this aerodynamics science project, you will change the basic design of a paper plane and see how this affects its flight. Specifically, you will increase how much drag the plane experiences and see if this changes how far the paper plane flies. There is a lot of cool… Read more
The Science of Launching an Airplane by Catapult
Science Fair Project Idea
Scientific Method
Naval fighter pilots seem to defy physics each time they fly their jets off of an aircraft carrier. Normal runways are thousands of feet long so that airplanes can develop enough lift to fly. But a runway on an aircraft is much shorter. How can naval pilots get their fighter jets into the air without falling off the carrier into the ocean? Well, because they get a boost from a catapult! Sounds unbelievable? It's not, and you can find out more about catapult-assisted takeoff in this aerodynamics… Read more
Baking Soda and Vinegar Rockets
Science Fair Project Idea
Scientific Method
Watching a spacecraft launch is an amazing experience. It is thrilling to see it lift off and escape Earth's gravity. Did you know that it takes a chemical reaction to get a spacecraft into space? Every time you see a one blast off, you are watching chemistry at work. In this chemistry science fair project, you will also get to blast an object into the air. You will not be using the same fuel that NASA uses for the rockets that launch their spacecrafts; instead, you will use two simple… Read more
Make a "Whirlybird" from Paper
Science Fair Project Idea
Scientific Method
Have you ever seen a maple seed twirling as it falls through the air? In this project you will build something that behaves similarly called a whirlybird. Will your whirlybird be able to stay in the air as you add paper clips as weights? Try this project to find out! Read more
Exploring Nanotechnology: Fold, Roll, & Stack Your Way to Super-Strong Materials
Science Fair Project Idea
Scientific Method
Advertisements for high-tech sports gear or the latest and greatest outdoor material promise lighter and stronger products every season. Is it a scam? How can engineers keep creating materials that are both lighter and stronger than anything known so far? The answer is in the nanoscale! Using nanotechnology, scientists can play around with the detailed structure of matter, leading to a whole new range of materials, some with amazing qualities. In this science project, you will get a glimpse… Read more
Knock Your Blocks Off: The Mechanics of Carnival Games
Science Fair Project Idea
Scientific Method
"Hey kids, step right up! Toss this ball and win a prize!" shouts the carny barker. Sounds easy enough—until you try it. Why are those "simple" games at the fairs, carnivals, and boardwalks so hard? Is it really lack of skill or coordination or do those concessionaires use some basic laws of science to help them set up the games in their favor? This science fair project can help you find out for yourself. Read more
A Battery That Makes Cents
Science Fair Project Idea
Scientific Method
Batteries are expensive, but you can make one for exactly 24 cents! In this experiment, you will make your own voltaic pile using pennies and nickels. How many coins in the pile will make the most electricity? Read more
Build a Simple Drone and Test How Much It Can Lift
Science Fair Project Idea
Scientific Method
How does weight affect a drone's speed? Is there a limit to how much weight a drone can lift? Find out with your own mini popsicle stick drone in this fun science project! Read more
How Sailboats Stay Upright
Science Fair Project Idea
Scientific Method
Have you ever seen a tall sailboat and wondered how they don't flip over when it's windy? Try this project and learn about the physics behind how sailboats stay upright. Read more
