STEM at Home — Water Filter Engineering Kit
Engineer a real water filtration system at home and tackle one of the world's most important challenges. Pairs directly with EdTech Academy's Workshop 6: Environmental Science — Build a Mini Water Filter (July STEM Workshops 2026).
Students build a layered filtration system using gravel, sand, and cotton to clean muddy water — discovering how each layer removes different-sized particles. Connects hands-on engineering to global environmental science and public health.
Kit includes:
Small gravel (pre-measured bag)
Fine sand (pre-measured bag)
Cotton balls (10)
Coffee filters (4)
Plastic funnel
Muddy water mix (dry powder — just add water)
2 collection cups
Instruction card with experiment guide
Student supplies at home: Empty plastic bottle (cut in half), water
Grades K–8 · Pairs with July Workshop 6 · Ships in 2–3 days
