Free Build Library
Start with cardboard, code, household materials, brick-compatible parts, or robotics kits.
Library
Draft cards are clearly marked until full BricklabClips demos are linked.
Showing 10 starter guides.
Build a large pressable button that can demonstrate switches or connect to a simple classroom game controller.
Cardboard, Foil, Tape, Paper clips, Optional microcontroller
Use cereal boxes instead of craft cardboard, Use binder clips instead of paper clips
Circuits, Inputs, Prototyping
Create a simple vehicle powered by a rubber band, then tune wheel size and axle friction.
Cardboard base, Rubber bands, Skewers, Bottle caps or wheels, Straws
Use recycled lids for wheels, Use pencils for axles
Stored energy, Friction, Iteration
Lift a small platform using a simple pulley system and compare single-pulley and multi-pulley designs.
String, Small box, Pencils or dowels, Tape, Weights
Use paper cups as the elevator car, Use binder rings as pulley wheels
Simple machines, Mechanical advantage, Load testing
Compare how gear size changes speed and torque using a compact hand-crank demonstration.
Brick-compatible gears, Axles, Base plate or cardboard frame, Handle
Use printed paper gear templates, Use bottle caps with hand-cut teeth for a rough demo
Gear ratios, Torque, Speed
Design a marble run that slows, turns, and lands consistently within a target zone.
Cardboard tubes, Tape, Marbles, Paper cups, Recycled packaging
Use paper strips as rails, Use rolled newspaper for supports
Gravity, Energy transfer, Testing constraints
Build bridges from paper and test how folds, arches, and trusses change strength.
Printer paper, Tape, Books, Coins or washers
Use newspaper, Use index cards
Structures, Compression, Load distribution
Create a small score-based game that can pair with a physical cardboard controller.
Computer or tablet, Scratch account optional, Design worksheet
Use offline Scratch, Use MakeCode Arcade if available
Loops, Events, Variables
Create a sequence of at least five linked actions that completes a useful or funny final task.
Domino-like objects, Cardboard ramps, String, Cups, Balls
Use books, blocks, or recycled containers, Use paper ramps
Cause and effect, Energy transfer, Systems thinking
Safely wire a small motor and compare blade shapes for airflow using lightweight paper blades.
Small DC motor, AA battery pack, Switch, Paper blades, Tape
Use a recycled toy motor with adult supervision, Use cardboard blades instead of plastic
Circuits, Motors, Blade design
Prototype a grabber arm with cardboard linkages before adding optional electronic control.
Cardboard, String, Straws, Brads, Optional servos, Tape
