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.
"Flu season" is something we deal with every winter. Cyclical or seasonal outbreaks of an infectious disease can occur for a variety of reasons, such as seasonal changes in host behavior (for example, more people staying indoors), the seasonal abundance of disease carriers (for example, mosquitos), and many others.
Another factor that can play a role in cyclical outbreaks occurs when the natural immunity to a disease has a short duration. This enables each individual in the population to…
Do people treat someone differently based on his or her appearance? Specifically, how are their behaviors affected by the clothes a person wears? For instance, if somebody wears a formal suit, do you think others behave differently when interacting with that person compared to if he or she were wearing casual clothes, like blue jeans? In this science project, you will get to try and find out!
Does talking on a cell phone make one a more dangerous driver? Here is an experiment you can do to investigate whether reaction time is adversely affected by a simultaneous phone conversation.
Though the Sun provides heat and light, which are essential for life on Earth, ultraviolet (UV) rays in sunlight can cause damage to DNA. In this science fair project, you will experiment with a strain of yeast that is super-sensitive to UV light. This project will demonstrate the lethal effects of UV light when DNA damage is not repaired.
Objects that glow in the dark hold a special place in the imagination of both children and adults. The lights go out at night, but these odd things refuse to disappear. Where does the light come from? Do they work in any climate? In this science fair project, you will make a very simple electronic device to measure the light given off by luminescent materials. The device will be used to study how temperature affects luminescence.
Have you ever seen a chemical reaction that makes a solution change color? Probably. But what about a solution that changes color and then changes back, not only once, but many times? Sounds pretty exotic! Whereas most chemical reactions only move in one direction from reactants (starting chemicals) to products, in these rare oscillating reactions, the reaction products appear and disappear for a number of cycles. Because the products are colored, the solution appears alternately blue, then…
We encounter an amazing array of colors every day, from the greens of plants and the many colors of their flowers, to the pinkish blue of a sunset, to the artificial coloring in beverages. How do we perceive all of these colors? When light hits an object, some of that light is absorbed by the object, and the light that is not absorbed is what we see. In this science project, you will build a simple spectrophotometer from a cell phone and use it to investigate how visible light is absorbed by…
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.
This is a modern version of a classic experiment by Robert Boyle on the compressibility of gases. Boyle discovered the relationship between pressure and volume of gases that now bears his name. This project shows you a simple method for re-creating this famous experiment.
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,…
