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.
Did you know that your heart beats at different rates depending on what you're doing? The more physically active you are, the faster your heart beats. You can measure the rate your heart is beating by taking your pulse. This science fair project will show you how to take your pulse and help you investigate which daily activities get your heart beating the fastest.

Have you ever mixed together salt and sand? It is fun to see how all of those tiny grains of salt and sand mix together! But what if you had to separate them out again? Do you have nightmares of tiny tweezers, a magnifying glass, and hours spent picking grains of salt and sand apart? Do not be afraid, there is another way! In this chemistry science project you will use the differences in solubility between salt and sand to find out the simple "solution" to this problem.

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!

Smog days are often posted in your local newspaper. Check how many smog days your city has had in the last year. How does it compare to to other years? You can also take pictures of your city landscape on high and low smog days. How do the pictures compare? How does smog in the atmosphere affect visibility? What is smog made of? You can use tongue depressors smeared with Vaseline to check for smog particles in different areas; just stick in the ground and look at them a few days later. …

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?

Isn't it nice to take a nice, hot shower or bath after a long day of playing outside? But have you really thought about how the hot water in your shower or bath gets hot? Sure, the water heater in your house gets it hot, but what makes the water heater work? Water heaters are powered by natural gas or electricity. But are there any other ways to heat water? What about using the Sun? In this science fair project, you'll give it a try by capturing energy from the Sun to heat water.

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!

Do you like to watch outdated science fiction and cheesy horror movies? Many fictional tales of cloned organisms have been created based upon the scientific method for cloning animals or plants. In the real world, the cloning of plants is a common method used in modern farming. How do you clone a plant?
In this science project you will get to find out by making your own cabbage clones!
