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.
Does green apple juice taste the same as red apple juice? That might seem like a silly question. Food coloring does not have any flavor—so how could it change how something tastes? Find out whether it does in this food science project!
"Plastic made from milk" —that certainly sounds like something made-up. If you agree, you may be
surprised to learn that in the early 20th century, milk was used to make many different plastic
ornaments —including jewelry for Queen Mary of England! In this chemistry science project, you can figure out the best recipe to make your own milk plastic (usually called casein plastic) and use it to make beads, ornaments, or other items.
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…
Have you ever wondered why apple slices turn brown once you cut them, or why a yellow banana gets dark spots over time? In this project you will find out why this happens, and how you can keep your apple slices looking fresh!
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?
This experiment is for all the kids out there who love boiled cabbage! You say you do not like cabbage? Well maybe you will like this amazing color-changing liquid you can make with cabbage. Which solutions around your house can make the cabbage juice change color? Find out while you learn about acids and bases and how to test for them.
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.
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?
Here is a riddle for you: what kind of rock grows? The answer is: rock candy! This delicious candy is actually crystallized sugar and you can "grow" it from a sugar-water solution. In this science fair project you'll learn how to grow your very own rock candy and determine if using seed crystals changes the growth rate of your sugar crystals.
