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.

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
Abracadabra! Levitating with Eddy Currents!
Science Fair Project Idea
Scientific Method
Did you know that not all trains run on tracks? Some of the world's fastest trains are magnetic levitation trains (maglev). This means that the carriage of the train is suspended over the rails with no support, but only with magnetic fields! There is a physical explanation for magnetic levitation, and if you would like to learn more about magnetism and current, this is a science fair project that you must try! Read more
Are Enzymes in Laundry Detergents Effective Stain Removers?
Science Fair Project Idea
Scientific Method
Some laundry detergents have added enzymes that break down proteins, helping to remove them from the cloth fibers, and thus remove stains. You can perform a scientific test of these enzymes' stain-fighting ability. Do background research on the enzyme(s) in the detergent, and on the substances you choose for making the stains. Try to predict for which substances the enzymes will be effective. Cut a piece of light-colored cotton cloth into identical 10 cm squares. Choose different… Read more
Are Laminates Stronger?
Science Fair Project Idea
Scientific Method
If you love to hit the half pipe with your snowboard or skateboard, then you have tested the strength and durability of laminates. Laminates are sandwiches of different materials that are glued together in layers to give strength and flexibility to an object. In this experiment, you can test if laminating wood can make it stronger and able to support a heavier load. How much weight can it take before it breaks? Read more
Art Bot: Build a Wobbly Robot That Creates Art
Science Fair Project Idea
Scientific Method
Do you like drawing or painting? What if you could build a robot that creates its own art? In this project, you will create your own Art Bot, a robot with markers for "legs" that wobbles across a piece of paper, creating drawings as it moves. You can then customize your robot to change how it draws. This is a beginner-level project with no robotics experience necessary, so if you want to try building your own robot, this is a great place to start! 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
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
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
Build a Simple Underwater Robot
Science Fair Project Idea
Scientific Method
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. Read more
Build a Water Clock to Show the Drip, Drip, Drip of Time
Science Fair Project Idea
Scientific Method
What are some of the ways we keep track of time? We have alarm clocks, wristwatches, and cell-phone clocks, to name a few. Just a few hundred years ago, our ancestors did not have any of these conveniences, yet they found ways to tell time. How? By using devices such as water clocks. In this science project, you will follow in the footsteps of early engineers and build a water clock that tracks time for three hours. Read more
