Innovating Science® STEM Investigations: Design a Water Filter Kit

Grades 6–12

Do your students know how the water that comes out of their faucets is made safe to drink? 

With this kit, students will learn about the processes performed at water treatment facilities and then engineer their own small-scale filtration plant. Once they design their filtering system, they will observe and evaluate the quality of the water they produce. 

Each kit contains materials for 15 groups of students. NGSS-aligned teacher’s guide and student study guide copymasters included.

Kit includes:

• 1500 g fine sand
• 1500 g gravel
• 300 g activated charcoal
• 5 ml green food coloring
• 25 ml white vinegar
• 30 coffee filters
• 1 bag cotton balls
• 75 plastic cups
