Description

The whole class is on the edge of their seats, staring, as turbine blades twitch, gain speed, and start to whirl! Gears are spinning faster and faster as the cylinder pulls in water and pushes it out. It’s working – they’re pumping water! Kids will try different blade designs, gear ratios, and raid the recycling bin for new blade materials. TeacherGeek makes it a breeze to modify and redesign turbines, which means kids really get to see how variable changes can affect the performance of their designs. Grades 5 – 12+ (different documents for different ages). Some adult assistance is helpful for 5th-graders. TeacherGeek is not a toy; it’s way better! Kids love making real things, especially when they get to use age-appropriate tools. Kids will need a TeacherGeek Reamer (1 included in each 10-pack), Phillips screwdriver, scissors, tape, and a fan (to create wind).
