This is the story of Goldie, her friend Ruby, and a princess pageant with a twist. Help Goldie and Ruby build a float for the princess parade. You did it! Take your machine for a spin and try other designs.

With this kit, kids can work on observation and memory skills, learn animal facts, and practice logic and deductive reasoning.

"The Engineer-a-coaster activity kit is a fun, hands-on way for children to explore concepts like size, speed, gravity, angles, and motion. Through trial and error, children will explore STEM concepts by experimenting with track angles and placement and observing results as the discs roll along the tracks into the goal box"--Instruction guide

"Students discover how simple machines make work easier as they build realistic models and perform hands-on experiments. Comes with 7 step-by-step experiment cards that walk students through how to build and use a pulley, an inclined plane, a wheel and axle, and more. The cards include information that explains each machine nd how it's used in the real world."--Publisher's website.

"With this fun, engaging kit, students explore concepts like gravity, force, motion, momentum, and speed--while building 21st-century skills like perseverance and problem solving! Students simply use a challenge card and contraption components to set up a chain reaction course. Then they test the course themselves--adjusting placement, distances, and angles until it works perfectly. Students can even create, test, and perfect their own chain reactions"--...
