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

Everyone knows electricity can create heat, especially because our electrical appliances tend to warm up when turned on. But wouldn't it be cool to do the reverse — generate electricity from heat? In this science project, you will study why it happens, measure the effect, and then use the phenomenon to build your own device, a thermocouple thermometer, that will enable you to convert heat into electrical energy.

In physics class, you have probably rolled your eyes at some point after being assigned a "projectile motion" homework problem where you use equations to predict how a ball will move through the air. This experiment will show you just how fun that problem can be by using a real catapult to launch a ball and videotaping it as it flies along its path. Then, you will analyze the video and compare it to what the equations predicted. If you have ever wondered if those equations in your physics… Read more

Have you ever wanted to analyze data from a NASA spacecraft? In this science project you will use data from NASA's MESSENGER mission to measure the diameter and calculate the depth of impact craters on Mercury. You will then analyze that data for relationships between a crater's depth and diameter. This is your chance to perform a science project as a NASA researcher would! Read more

Are you an artist, or do you enjoy the process of making art? What kind of art do you create? Do only humans make art? Not all the time. Robots can create art, too. Robots can be programmed and "taught" to do all kinds of things, such as delivering medications to hospital patients or putting together a car on an assembly line. The Vangobot™, shown in the video below, paints pictures with brushes and paint, and in a distinct, unique style—just like a human artist. Watch… Read more

Are you interested in the technical and ethical aspects of genetic screening, forensic science, and DNA fingerprinting? Scientists use different forms of a gene, called alleles, to differentiate between two fingerprints. One such sequence used in human DNA fingerprinting is the Alu repeat (a 300 base pair repetitive sequence of DNA) on chromosome 16. During evolutionary time, up to 1 million copies of the Alu repeat have become randomly inserted throughout the human genome. Within a specific… Read more

Imagine how cool it would be to have your own motorized robot hand. Well, stop imagining and turn that daydream into reality! Start out by designing and building a robot hand. The Science Buddies project Grasping With Straws: Make a Robot Hand Using Drinking Straws shows you a simple way to make a robot hand with drinking straws, or you can design a robot hand from any other materials you think are suitable. Your hand design will need sewing threads, or some other mechanism, for motors to… Read more

Scientists recently found that some small drugs can stop infection by the deadly Ebola virus in its tracks. Lab researchers found that these drugs bind to a protein that the Ebola virus uses to enter our cells, and this is how infection is prevented. However, this also means that the bound protein no longer functions in our cells. How might these drugs accidentally disrupt important biological processes in our bodies? What other proteins might these drugs bind to? In this science project,… Read more

Maple syrup on pancakes, ripe bananas, and soft drinks are all foods that are tasty to us because of the sugar in them. But did you know there are different kinds of sugar? One food can have multiple kinds of sugar in it, and our bodies actually process the different types of sugars differently. In this science project, you will measure the concentration of two sugars—glucose and sucrose—in different foods, and investigate how sucrose is converted into glucose with the help… Read more

In the first decade of the 21st century, scientists found ways to make one adult cell type turn into a completely different cell type. This has huge implications for the medical field, including being able to take some cells that a person could spare, such as skin cells or blood cells, and turn them into another cell type that might be much more important for that person to have, such as cells to make a new kidney. How are scientists able to accomplish this amazing feat of "reprogramming" the… Read more

Unlocking the three-dimensional structure of a protein is crucial to help scientists understand how it functions in our bodies and how it can cause devastating diseases if it becomes disrupted or interacts in the wrong way. However, figuring out the structure of a protein in three-dimensional space can be very challenging. Proteins are the functional units of our cells, and every protein is made up of a long chain of amino acids. Amino acids come in different shapes and sizes, and they have… Read more
