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.
Do you wake up at the crack of dawn, or do you need an alarm clock to wake you up each morning? It may surprise you that the two are not always in synch. Nowadays, we use Standard Time to set our watches instead of Solar Time. Which method of timekeeping is the most accurate? Get ready to synchronize your watches!
Timekeeping is the science of how to keep time with precision and accuracy. People have been finding ways of measuring time for thousands of years, usually based on the movements…

You can take advantage of electrochemistry and make a battery to clean tarnished silverware without scrubbing. You should learn about how batteries work and study oxidation-reduction reactions so that you can explain how this process works. You'll need a pan large enough to hold the pieces of silverware, and deep enough to cover them in solution while boiling gently. Line the pan with aluminum foil, and place the silverware inside the pan, making sure that each piece touches the foil. Add…

Everyone has experienced the warmth provided by a shaft of sunlight through a window. In this physics science fair project, you will determine how the color of an object affects the amount of radiant energy that is absorbed. You will then use the Stefan-Boltzmann equation to determine the amount of energy that is absorbed and re-emitted by the different colors.

Research the famous collapse of the Tacoma Narrows suspension bridge.
What lessons were learned about the potentially damaging effects of wind on bridges? What structures stabilize a bridge against wind forces? Build models and use a wind tunnel to test your hypothesis.

We rely heavily on our senses to tell us about our environment. But in addition to the senses of touch, smell, taste, hearing, and sight, some animals are able to sense Earth's magnetic field. Migratory turtles and birds use this sense to guide them on long journeys. Homing pigeons use it to find their way home. New research suggests that large mammals, such as cows and deer, may also have the ability to sense the direction of magnetic north. In this animal behavior science project, you will…

Experience with Microsoft® PowerPoint® would be helpful. You will also need a computer that can run Google EarthTM and that has Internet access.
Antibiotics work by destabilizing the metabolism or cellular structure of bacteria, preventing growth, and causing bacteria to die. Some strains of bacteria have mutated and found a way to resist the actions of antibiotics. These are called resistant strains because they resist the actions of available antibiotic treatments. There are many different types of antibiotics that are continually being developed to combat new strains of resistant bacteria. Some antibiotics work better on different…

Build a Paper Speaker activity or the
project, or you just like music and are interested in exploring more about the science of sound, then this project is for you.
You probably know that sound waves can have different frequencies. If not, you can read more about that in the background section
of the
project. The range of human hearing is typically about 20 hertz (Hz) to 20,000 Hz. Frequencies at the lower end of this…

Time Required
Average (6-10 days)
Prerequisites
None
Material Availability
Specialty electronics items required.
Cost
Average ($40 - $80)
Safety
Always keep speaker volume at safe levels to avoid hearing damage.
Beats are a pattern of oscillating sound intensity (i.e., the volume of the pattern grows and fades with a regular cycle). They occur when two tones of almost equal frequency interfere. People can perceive beat frequencies below about 7 Hz. Figure out how to create sound files to play pure tones on your computer. Create files with a pure tone of one frequency in the left channel, and a pure tone of a different frequency in the right channel. Systematically explore different frequency…

Most of the energy and fuel that we use in the United States is derived from burning fossil fuels. Fossil fuels are the remains of plants and animals that lived hundreds of millions of years ago. Examples of fossil fuels include coal, petroleum oil, and natural gas. Burning coal releases 21.3 gigatons of carbon dioxide— a greenhouse gas that may be responsible for global warming and climate change—into the air in one year. About half of this amount is absorbed by natural processes…

Time Required
Long (2-4 weeks)
Prerequisites
This science fair project must be performed in a well-ventilated area; a fume hood is recommended. You must also have a teacher who can help you order the necessary chemicals.
Material Availability
Specialty items are required. You will need methanol, and either potassium hydroxide or sodium hydroxide. See the for more information.
Cost
High ($100 - $150)
Safety
Minor injury is possible. You must wear safety goggles and gloves when dealing with chemicals. Do not breathe in fumes from the chemicals. Read and follow the suggestions in the .
Most people are not aware that the soil around them is a battle scene. The combatants are very small—bacteria on one side and bacteriophage on the other. The bacteriophage (or phage for short) try to pierce the outer coats of the bacteria and inject them with phage DNA. If successful, the DNA will take over the inner machinery of the bacterial cells and force them to make many copies of the phage. After the copies are made, the bacterial cells break apart, releasing new phage that start…

Time Required
Long (2-4 weeks)
Prerequisites
This is an advanced science project that requires access to a laboratory with a water bath and 37°C incubator. The kit you will use has enough supplies to perform the procedure one time. To repeat the procedure, you should order additional supplies (listed in the Materials and Equipment section), or make your own media and agar plates. Working with a science teacher or other mentor who is familiar with growing bacteria and titering phage would be helpful.
Material Availability
You will need to order the bacteria, the phage, and the supplies from an online science supply store. See the Materials and Equipment list for details.
Cost
High ($100 - $150)
Safety
The bacteria (E. coli B) and the phage (T4r) are not dangerous, but you should follow common-sense safety guidelines and wear gloves and safety goggles when working in the lab. Adult supervision is recommended.
