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.
Math is used by many different types of scientists to model phenomenon and evaluate data from an experiment. By building mathematical models scientists can understand how different physical, chemical, and biological processes are affected by different variables. The most important tools are: making a graph to give a visual representation of the relationships between your variables and making an equation to give a way of computing the relationships between your variables. Find a source of data,…

Do you hate shots? Do you complain about paper cuts? Imagine if you had to give yourself shots a couple of times a day, as well as prick your finger, on purpose, even more frequently. Of course, if you have diabetes you do not have to imagine this; it is your reality. People who have diabetes usually need to keep close track of how much sugar is in their blood (called their blood glucose levels) by testing a drop of blood from a finger prick. If there is too much sugar in their blood, some…

Time Required
Average (6-10 days)
Prerequisites
Some familiarity with electronic circuits and using breadboards would be helpful, though it is not required for this project. Completion of a basic chemistry class is also recommended before trying this project.
Material Availability
A pump and other electronics parts must be specially ordered to do this project. See the Materials list for details. Estimated project time includes shipping of specialty components.
Cost
Average ($40 - $80)
Safety
Some parts of the circuit can get warm during normal operation. Do not leave the circuit operating when unattended. Be very careful with your wiring to prevent short circuits from happening; short circuits can get very hot and cause plastic parts of the circuit to melt.
Earth, the Sun, wind, and water are all sources of renewable and sustainable energy—and sources you probably already know about. But did you know that you can get energy from such things as banana peels, coffee grounds, and newspaper? In a process called composting, you can transform kitchen and other solid wastes into a product that is beneficial for your garden: homemade fertilizer. As the waste decomposes, it also creates heat. Can this naturally created heat be put to use? In this…

Time Required
Very Long (1+ months)
Prerequisites
Making a compost pile can take anywhere from a couple of days to a few weeks, depending on the method and bin you use. In this energy and power science fair project, you will spend a few days creating a compost pile. You will have to account for the time as you are planning your science fair project. You will also need to be home for several hours at a time on many specific days throughout this project. Read through the Experimental Procedure for more details.
Material Availability
You (and friends, if possible) will have to start collecting potato peelings or grass clippings a few weeks in advance to accumulate enough, so keep this in mind when budgeting time for your science fair project. See the Materials and Equipment list for details.
Cost
Very High (over $150)
Safety
Wear safety goggles and use caution when working with all tools. Be sure to wear disposable gloves when handling animal waste and to clean all of the work surfaces thoroughly with a bleach solution. Read the Science Buddies to learn how to experiment safely.
Students who are mathematically inclined can use the student version of a program like MatLab or Mathematica to convert a digital image into numbers, then perform operations such as sharpening or special effects. This is a great way to learn about image processing algorithms.

Is there a correlation between birth order and grade point average? Design a survey study to find out. How many completed surveys do you need for a representative sample of your school? If you limit your survey to one school, would you expect it to be representative of a larger population (such as your county or state?) How do you control for potential effects of parental age at birth? (In other words, younger siblings will have a higher probability of being born to older parents. If there…

How do you feel when a friend comes too close to you? How far away or close do you think is necessary to have a conversation with someone? The answers to these questions are dependent upon the size of your personal space. Some people like to be within a foot of each other when having a conversation and others feel that being 3 feet apart is still just a little too close for comfort.
Personal space is defined as the protective area surrounding a person's body (not necessarily spherical in…

You should have access to a large number of children between the ages of 5 and 12 years old.
Material Availability
You might need a video camera in order to record conversations between children.
Think about mountain ranges, canyons, sand dunes, or any other interesting geological feature you may live near enough to visit. The surface of the Earth is always changing due to a balance of forces both above and below the surface. Below-surface forces cause the Earth's crust to be faulted, folded, tilted, and lifted. Above-surface forces are primarily due to the natural processes of weathering and erosion. Can you show the effects of these forces using scale models, demonstrations,…

Before cannons widely replaced them, siege engines were often used by armies to throw large stones and other projectiles to break down castle walls. One of the most advanced siege engines used in the Middle Ages was the trebuchet, which used a large counterweight to store energy to launch a payload, or projectile. The horizontal distance the payload would travel is called the trebuchet's range. Figure 1, below, shows a modern reconstruction of a trebuchet.
The range of a trebuchet has…
