Fourth Grade Science Projects (273 results)
Science Buddies' fourth grade science projects are the perfect way for fourth grade students to have fun exploring science, technology, engineering, and math (STEM). Our fourth grade projects are written and tested by scientists and are specifically created for use by students in the fourth 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, fourth 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.|

Imagine how cool it would be to build a robot hand that could grasp a ball or pick up a toy. In this
robotics engineering project, you will learn how to use drinking straws, sewing thread, and a little
glue to make a remarkably lifelike and useful robot hand. What will you design your robot hand to do?
Pick up a can? Move around a ping pong ball? It is up to you! With these starting instructions, you can
design any type of hand. You will simulate human finger anatomy as the basis for a…

Physicists sometimes study matter under extreme conditions. For example, think of the emptiness of interstellar space vs. the unimaginable crush of pressure at the center of a neutron star, or an object dipped in liquid nitrogen vs. the tiles on the space shuttle during re-entry. Here's an experiment on permanent magnets in "extreme kitchen" conditions that you can try at home.

Have you ever suffered from poor Wi-Fi reception for your smartphone, tablet, or laptop? Certain materials can actually block a Wi-Fi signal; do you think that could be part of your problem? In this science project, you will do an experiment to find out which materials cause the biggest drop in signal strength from a wireless router.

Playing basketball can be hard work. Players not only constantly run around the court, but just dribbling the basketball takes a lot of effort, too. Why is that? It has to do with how the basketball bounces. When the ball hits the court, its bounce actually loses momentum by transferring some of its energy into a different form. This means that to keep the ball bouncing, players must continually put more energy into the ball. In this sports science project, you will determine how high a…

It has been said that, "Life is like a box of chocolates—you never know what you're going to get" (Forrest Gump in Forrest Gump, 1994). In this science project you can test the "Forrest Gump Chaos Theory" by using M&M's®, which are much cheaper than a box of chocolates. What if life is more like a bag of M&M's? Find out in this science project if some things in life are predictable by using the awesome power of statistics.

Have you ever seen or heard of the movies The Mummy or The Mummy Returns? Mummies have always played a part in nightmares for Western cultures, but in ancient Egypt, mummification was a serious religious ritual. They believed that preserving human remains was necessary so that the previous owner could enjoy the fruits of the afterlife. In this science fair project, you will learn about the rituals and science of mummification by mummifying a hot dog.
