Science, technology engineering & math (STEM) projects

Discover the scientist within you through hands-on activities in rocketry, robotics, biofuels, renewable energy, wild life, computer science and more. And build skills that can form the foundation of a future career.

Aquatic Robotics

Learn science, engineering, technology and math skills to design and build your own remote-operated vehicle, then adapt it to monitor the water quality of Minnesota's rivers, lakes and streams.


Learn about navigational tools - GIS and GPS - and orienteering


Learn about building and maintaining computers, software and the internet.


Learn about equipment, lighting and flash techniques, photo composition, and evaluating photographs.

Small engines

Learn about building and maintenance, tools, rules and regulations, safety issues, and careers.

Shop: wood & metal

Learn techniques and skills to use routers, joiners, table saws, tape measures, drills and more.

Power of the Wind

Explore wind as an energy source as you design, build, and test wind-powered devices!

Wildlife biology

Learn about wildlife populations and habitats, and how to become a good steward of the land.


Study lakes, aquifers, caves, streams, iron deposits, rocks, and fossils.

Crop science

Learn about Minnesota crops, soil fertility, weed and insect pests, food storage and business.

Animal science

Love animals? Learn about selecting, feeding, managing, caring for, judging, training and showing animals.


Use science, math, engineering and technology to design, build and program a robot.


Learn about the science of flight. Build a rocket, airplane or hot air balloon.


Learn about video production and filmmaking, including composition, camera and lighting techniques, and editing.


Build circuits and test voltages. Learn about wiring, lighting, and safety issues.


Learn about maintenance, restoration and operation, fuels, hydraulic and electrical systems, and safety.


Learn how to choose a bike, bike maintenance and repair, and road rules to make riding safe and fun.

Water & wetlands

Learn about ecosystems, water quality and the lives that depend on the state's wetlands - including our own.

Plant & soil science

Learn about parts of a plant, photosynthesis, cross-pollination, soil, erosion and more.


Learn about insect collecting, experiments, research and careers.


4-H Cloverbuds explore and learn about the world in a non-competitive environment by doing fun activities with the guidance of parents or other adult helpers.


If you find that no single project is quite right for you, you can develop your own project. Be your own researcher, scientist, artist, communicator, and evaluator. Ask your local 4-H leader or Extension staff for resources to help create your own project area.

Engineering Design Challenge: Rube Goldberg Machine Contest

The 2014 challenge is to build a Rube Goldberg Machine with your county team. The challenge encourages critical thinking, creativity, innovation and problem solving in a non-traditional learning event while having fun! Young people in third through eighth grade can compete in these friendly science, technology, engineering and mathematics (STEM) competitions, which take place BOTH online and at county fairs.

4-H National Youth Science Day

Each year millions of young people become scientists for the day during 4-H National Youth Science Day (NYSD). This event, which takes place in urban, suburban and rural communities all across the nation, seeks to spark an early youth interest and leadership in science, technology, engineering and math (STEM) careers in an effort keep America competitive in those fields.
