11th Grade Science Fair Projects to Wow Everyone

Newton’s Cradle

A Newton’s cradle may seem like a simple enough project to create.

However, you can explore more topics and ideas through this easy science project.

Not only can you learn more about momentum and energy, but you can also learn more about mass and collisions.

Some concepts that you will explore include the conservation of momentum and energy, the law of motion, and gravity.

Supplies that you would need are popsicle sticks, marbles, glue, scissors, tape, pencil, and hot glue.

Mouse Trap Car

One of my favorite high school projects was the mouse trap car.

This project is perfect for all grade levels and can be advanced through more complicated materials or designs.

Try this project if you like to experiment with building speed, creating efficient designs, and reducing friction.

Plus, you will get to explore more concepts like the conservation of energy, rotational energy, potential and kinetic energy.

Also, this is a simple project that only requires materials like a mouse trap, CDs, a structured body, and anything else you decide to add.

I remember creating one during high school and I used chopsticks for the lever, CDs for the wheels, and cereal boxes for the car.

After several alterations, my mouse trap car was lightweight and able to travel across the entire classroom (which was required to get an A on the project).

Marble Roller Coaster

Another one of my favorite high school science projects was the marble roller coaster.

This is one of the classics, so you should add in a little twist to stand out from a slew of science fair projects.

Moreover, you will learn about concepts like the change from potential to kinetic energy, the conservation of energy, the effect of friction, centripetal forces, and acceleration.

All you need for this project are some marbles (hence, the name marble roller coaster), tubing or some other sort of material for the roller coaster, tape, and support for the entire project.

Make sure to test your designs several times (many, many times) and try the design that is the fastest.

Also, take into consideration friction and think about what you can do to reduce it or counter it through different materials or ways of construction.

Effect of Color on Taste

This upcoming project was created during psychology class and it was so much fun.

First, you need a packet of Skittles and check how the color may affect someone’s perception of them.

You want to test it once when they are blindfolded, and another time when they are not to see if there are any differences.

In addition, you can also use other food items to test this phenomenon.

Record down any differences or findings when testing with a blindfold versus without.

Some fun concepts that you will learn are the importance of scent on our taste, the effects of our senses, and how our brain operates.

Sleep Activity

Have you ever wondered what happens when you sleep?

This might be a slightly more difficult project to work on since you need your participants to be asleep to record the information and findings.

Some concepts that you will learn are brainwaves, sleep patterns, and how your brain works when you go into the different stages of sleep.

Learn about REM sleep, deep sleep, and your circadian rhythm.

All you need are some participants, sleep-measuring tools, and a notepad to record your findings.

Effect of Video Games on Concentration

Another fun science fair project is checking how playing video games can affect one’s concentration.

You can either go for helping with concentration or distracting.

Some concepts that will be touched upon include concentration, how the brain works, and attention span.

These projects also involve a bit of psychology so you will be able to venture into both fields.

Also, the tools that you need are one or a few different video games, a quiz, and a timer.

You can have your participants play some video games and do an attention task.

Then, have another group do an attention task without playing video games.

Another way is to have two groups-one group that plays ten minutes of video games and another none at all.

Then, have both groups perform an attention task and see how well they do.

Best Insulators for Boiling Water

A simple science fair project is using different types of insulation materials for boiling water.

You can use foil, bubble wrap, plastic wrap, ceramic mugs, glass, etc. to test how long water can stay insulated in each of those materials.

Moreover, you can check back each hour and see how much the temperature changes each time.

You might want to test these insulation materials several times and record the temperatures for several experiments.

Some concepts that you can explore are insulation, temperature changes, and more.

Magnetic Train

If you want to simulate how bullet trains work, then this science fair project will bring you into a deep dive.

Some materials that you would need are copper coil, batteries, magnets, and a cylindrical tool (water bottle, marker).

In this project, you can learn more about electromagnetism, electricity, and forces.

You could also make this experiment more complex by combining other projects with this.

For instance, if you like the marble roller coaster, why not try to combine the concepts in this magnetic train with your coaster?

Are there any ways that you can improve the speed or reduce friction to make the items go faster?

Baking Soda Bottle Rocket

Have you checked out the soda bottle rocket? One of the coolest 11th grade science fair projects to try is this soda rocket!

If you have then this baking soda bottle rocket will be familiar to you!

You can change some features with the rocket to try and achieve a goal.

Do you want your rocket to shoot the highest? Or do you want it to stay in the air the longest?

Whichever your goal, try to test out your experiment several times before settling on one method.

Also, you will need items like a soda bottle, scissors, baking soda, vinegar, and duct tape.

Interesting concepts that you will learn are chemical reactions, forces, and acceleration.

Rube Goldberg Machines

Have you ever watched Tom and Jerry Before?

You might have seen those complex traps that Tom or Jerry have made before to catch or prank the other.

It can be anything from a ball rolling to trigger some scissors to cut a string to unleash a bucket of water out.

This project executes a series of actions based on a simple effect.

It can be anything from pulling on a string, touching something, or opening a door.

If you want to create something similar, then this project is for you!

Furthermore, you can run wild with this project since you can use any type of material that you think you might need.

This is for the free-spirited out there who do not want to follow a specific set plan to create something.

Use your imagination and learn a variety of concepts depending on how  you build your project.

Popsicle Stick Reaction

If you like the experiment above, then you will also love this one.

Create a chain reaction with popsicle sticks to learn more about potential and kinetic energy!

All you need are popsicle sticks for this experiment.

You can also add mini trinkets in between like pom poms or glitter to make your project explode in sparkles!

Overlap popsicle sticks in a four and lattice design and keep building for as long as you want.

You can make it whatever length you like.

If you are more of an outdoorsy person and enjoy gardening, this project will fit all your needs!

First, discover a patch of soil for planting and find several different locations.

Look for an open area, one with trees or other plants around it, and one where you decide.

Then, record and analyze the growth of each seed based on their locations.

You can also place your plant outdoors and one indoors to see if there is any effect.

Some concepts that you will learn are photosynthesis and botany.

Effect of Soil on Seeds

Another fun project with plants is the effect of soil on seeds.

You can check the differences between various soil types on seeds.

Some materials that you may need are seeds, mini pots, soil, water, etc.

You can also learn more concepts like botany and growth.

If you want to go full out, you can also try both the experiment on the effect of location on seeds and the effect of soil on seeds.

Then, compose a report based on your findings and research.

Hopefully you found a project that you like and get started on it!
