Blocky Kart

"Blocky is my best friend!"  


Student quote after completing this lab, 

Del Rio Elementary.

Students learn about force as they watch Blocky Karts go down ramps. Will Blocky Kart go further with a steeper ramp? Students learn that balanced and imbalanced forces result in the movement of their karts. They show that motion is predictable by measuring the distance traveled by Blocky from different positions and inclinations of the ramp.

Relating Speed and Energy

NGSS 4-PS3-1  Show how an object’s speed is related to it’s energy. Use evidence to construct an explanation relating the speed of an object to the energy of that object.  Students take measurements with Mezzi measuring tape to characterize the movement of Blocky Kart colliding with a sled from different heights on a ramp.
