The Wisconsin 4-H Science, Technology, Engineering and Math (STEM) program area cuts across all program and project areas. Strong STEM projects use an inquiry-based learning approach, improve STEM abilities, provide opportunities to improve mastery-independence-belonging-generosity skills, are based on National Science Education Standards and are led by trained adults.

STEM also has specific projects in 4-H such as aerospace, water, computers, small engines, electricity, electronics, astronomy, energy and robotics.
