Keep it Simple
This consists of a rigid bar that pivots around a fixed point called a fulcrum, just like a seesaw or a crowbar
What is a lever
This is the essential process of programming the SPIKE Prime light matrix, display, or smart hub to show custom icons, numbers, or animations
What is coding the brick
This towering carnival ride uses a giant mechanical wheel and axle to rotate passenger cars high up into the air for a panoramic view of the entire fairground
What is a Ferris wheel
A carnival ticket booth sells ride passes at a unit rate of $3 per ticket. This is the total cost for a group of kids to buy 15 tickets
What is $45
This classic carnival game uses a rigid bar pivoting on a fixed point—a lever—so that hitting a target with a ball - it makes a big splash!
What is a dunk tank
This uses a grooved wheel and a rope or cable to lift heavy loads or change the direction of a force, commonly seen at the top of a flagpole or on window blinds
What is a pulley?
Located on the iconic yellow Smart Hub, this is the total number of input/output ports used to connect your motors and sensors
What is 6
This classic, fast-spinning carnival ride features cars attached to arms that rotate around a central pivot, using a motor and gear system to lift and tilt riders as they spin.
What is the Tilt-A-Whirl
A spinning carnival wheel has a radius of 5 feet. This is the total distance straight across the center from one side to the other
What is 10 feet
This classic carnival ride features rows of painted horses that rotate in a circle around a central post, relying on a large motor and a wheel and axle system to turn the platform
What is a carousel
This is made of two inclined planes placed back-to-back, used to split things apart, cut, or hold objects in place—just like an axe blade or a knife
What is a wedge
🌟 DAILY DOUBLE 🌟 This type of rotating Technic element is used to transmit motion and power from a motor to other parts of your build, coming in different sizes like 8-tooth, 24-tooth, and crown shapes
What are gears
This exciting, steep carnival ride uses a chain lift (which relies on a pulley and a motor) to haul cars to the very top of a track, before letting gravity pull them plunging down through twists and turns
What is a roller coaster
A roller coaster track climbs at a steep angle of 45 degrees. If you measured its supplementary angle on the opposite side of the support beam, it would measure this many degrees
What is 135 degrees
These long, rod-shaped plastic pieces feature a cross-shaped (+ sign) profile and are slid through beams and gear centers to hold pieces together while allowing them to spin
What are axles
This consists of a larger disk attached to a smaller rod or cylinder, working together to turn things easily, just like a doorknob, a steering wheel, or a pencil sharpener
What is a wheel and axle
These small plastic pieces—often colored blue or black—are pushed through the holes of Technic beams to securely snap and lock your robot's pieces together
What are pins
On this spinning carnival ride, riders sit inside colorful tubs that rotate around a central post while also being pushed in a circle by a large rotating platform, using a wheel and axle system
What is the Teacup ride
A gear train has a small driver gear with 4 teeth and a larger gear with 12 teeth. Written as a ratio in simplest form (1:what number), this is the missing value
What is 3
This simple machine is a flat, slanted surface that makes it easier to move heavy objects up or down to a higher level without lifting them straight up
What is an inclined plane
This is essentially an inclined plane wrapped around a central cylinder or post, commonly used to hold materials together tightly or lift things up, just like a jar lid
What is a screw
Useful for joining Technic beams, axles, and sensors, these tiny structural pieces—including black friction pins, blue long pins, tan axle-pins, and yellow angle connectors.
What are LEGO Technic connectors
This classic ride lifts and spins passengers in circles high in the air. As the central top crown rotates faster, combining rotational motion with a powerful pulley and gear system located in the tower housing
What is a swing ride
If a Ferris wheel completes 1 full rotation in 2 minutes, this is the total number of degrees the wheel rotates in 5 minutes
What is 900 degrees
🌟 DAILY DOUBLE 🌟 Once a roller coaster train reaches the very top of the track and is released, this invisible downward force takes over, pulling the cars down the hill without needing an engine.
What is gravity
