Do you need a science project idea for your second grade class? You came to the right spot! This article has a few cool ideas for you to present in your classroom.

Plant Growth

Have you ever kept plants in your house? No matter what season it is, you can have flowers and other leafy plants inside your home as long as they have a healthy diet of water and sunlight. Try keeping track of the plants you and your parents have in the house, and write down everything you see while they grow over a month. How many flowers are there, and what color are they? If some plants are bigger than others, where are they located in the house?


Did you ever notice how your shadow changes shape and size with the time of day? You can use these changes in your presentation. Have your parent or a friend draw an outline in chalk of your shadow in the middle of the day, and do the same thing in the morning and the evening. What kinds of things are you noticing about the shadows you are casting? How high in the sky is the sun when you make the outlines? If you have enough time, you can do this over a couple of months and also write down what you notice about the differences in sunrises and sunsets.

Paper Airplanes

Have you seen one of these thrown in class? You might be surprised at the slight adjustments you can make to a paper airplane to change its speed and direction. After you look up some directions on how to fold different styles, carefully take all of them with you to your class and let them take flight. How does each of their flight pattern look? What do the folds that you made in each piece of paper mean when you throw the airplane?

Balancing Objects

Try holding a pencil on the tip of your finger, and see how long it takes to fall off. How did the placement of your hand feel when the pencil dropped? Now do the same thing with a few other objects - a book on your head, a ball in your hand, a paper plate on your nose. Feel how your weight shifts whenever you are trying to balance, and how that weight contributes to keeping your object on its surface.

Getting Ideas

What kind of science do you like the most? If you want to try out's Science for Kids course, you might think of an area you want to explore for a project that didn't cross your mind before. Maybe something to do with weather, or space? The possibilities are endless!
