10 of the Best Engineering Projects for Middle School Students

Hands-on learning, especially through projects, can be a highly educational and enjoyable experience for middle school students. Young learners can use these projects to be inspired, ideate, experiment, iterate, and implement their proposals. Not to mention, hands-on project work is a great way to test and develop your problem-solving skills and creativity!

If you are a middle school student, undertaking an independent or group engineering project can help you explore your curiosity, gain teamwork experience, and learn more about how different day-to-day machines and structures operate. To help get you started, we have compiled a list of 10 engineering projects that you can use to get inspired and build upon:

1. Build-a-bridge project

What to do: You can explore the principles behind the different kinds of bridges by building a model bridge using materials like popsicle sticks, straws, spaghetti sticks, and other safe, household items. 

Here, you witness how different shapes and materials affect design and stability. Learn about the fundamental principles of bridge design (span, load, etc) and challenge yourself by setting minimum load targets, and freestanding sections, and even allot yourself a budget to simulate how civil engineers work with finite resources.

Skill sets: Basic knowledge of materials science and structural engineering. Before beginning the project, you should research the different kinds of bridges (arch, suspension, etc.). Problem-solving skills are also helpful. 

Ideal for: Students looking to build a range of skills and who are interested in structural engineering and architecture. 

Drawbacks: Requires space and a controlled environment so external factors (wind, people, etc) do not accidentally damage the model. Precision is paramount and you will also need a steady hand while building the bridge. 

Tips: Begin with simple bridge designs to understand the basics before moving on to more complicated models. Use resources like and Carnegie Mellon, which have bridge-building lesson plans.  

2. Build and test paper planes

What to do: Build paper planes with different designs and materials to see how their flight is affected. Learn how different forces like drag, lift, and thrust affect a plane’s ability to fly. When designing and testing, pay special attention to the kind of paper, wing size, and fuselage length. Maintain a ledger to record data like flight distance, air time, and a stability rating for each iteration. Once you have perfected your design, challenge your friends and classmates to a paper plane competition!

Skill sets: You need good precision and attention to detail when folding paper. Strong organization skills will help you record test flights and use this data to improve future models. During the experiment, you will develop problem-solving and analytical skills when investigating what makes one plane better than another.

Drawbacks: The experiment is not eco-friendly. We recommend using used sheets from offices, schools, etc. to reduce wastage.

Ideal for: All middle school students. The project is fun and is an enjoyable way to learn about basic physics concepts.

3. Construct a pizza box solar oven

What to do: Harness the power of the sun using this low-cost, eco-friendly solar oven and cook outside! All you need is some aluminum foil, black paper, plastic wrap, and basic art supplies like tape and a scissor. Once you design and build your solar oven, use it to compare how long it takes to melt items (for example, cheese or chocolate) compared to a regular oven. Take into consideration outside weather conditions and how they affect the box’s ability to produce heat. 

Skill sets: None required

Drawbacks: The efficacy of the oven can depend on outside weather conditions. Ideally, you need a lot of sunshine to obtain the best results 

Ideal for: Middle school students who have limited experience with undertaking hands-on projects

Tips: Build more solar ovens using different boxes and materials to see how they affect the internal temperature

4. Egg drop challenge

What to do: Design and build a landing craft that keeps an egg safe when dropped from a height! Learn about gravity and how it pulls objects with mass, and discover which padding materials can keep your egg safe. Make multiple iterations of your landing craft with different materials to see which works best. You can use internal and external padding and even combine materials. Test by dropping the egg from different heights — you can do this experiment with friends and see who designs the best craft!

Skill sets: You need to use your creativity to think of designs and materials that can keep your egg safe! 

Drawbacks: This experiment can get messy and wasteful. We recommend using a hard-boiled egg or an egg in a sealed plastic bag.

Ideal for: All middle school students. Students can use this project to learn more about aerospace engineering and the different forces acting on crafts re-entering the Earth’s atmosphere. You can make the challenge tougher by setting minimum drop times, limiting the number of iterations, and using only certain materials to further test problem-solving and critical-thinking skills.

Tips: Use online resources to structure the experiment and include readings on aerospace engineering.

5. Build an automatic pill dispenser

What to do: You can design and build a pill dispenser that gives you the assigned medication at the correct time! To undertake this project, you should have experience using software like Arduino. You will need a programmable motor that moves at certain times to dispense pills, an LCD to show the date, time, and a message, and LED lights and a buzzer to set a reminder alarm. 

Skill sets: Prior knowledge of a prototyping platform like Arduino, familiarity with designing and building circuits

Drawbacks: This project is more advanced and requires both prior knowledge and materials like a motor, clock, LED lights, and LCD, which can be expensive

Ideal for: Middle school students who want to do more advanced projects

Tips: Examine commercially available pill dispensers available in stores for inspiration — it can help you decide what innovation your project needs!

6. Magnetic levitating train

What to do: In this project, you will build a train without wheels! Begin by sourcing your materials: a magnet, a non-magnetic surface, and construction materials to build a track. This project will teach you about magnetic levitation and how magnetic fields generate a force. When constructing your train, experiment with different weights to see the maximum weight you can use to maintain levitation. 

Skill sets: Attention to detail and precision are important when building the enclosed train track to ensure levitation. Once built, adjust your model to ensure the train floats perfectly above the track, improving your problem-solving skills.

Drawbacks: You need to source specific materials for this project (monopolar magnetic tape, wooden blocks, etc) which can be expensive. Magnetic experiments can be tricky to get right the first time; achieving stable levitation requires patience.
