Data Sheet

Vary the weight of your project and see if that has any effect on the

strength of the vibration or the speed of the movement. Ask students if they

can observe how the center of gravity affects movement and speed.

Use a cardboard box and masking tape to create a race track. Have students

race their engineered robots to the ﬁnish line.

5. Snap off Circuits

The circuits can be snapped off of the board and embedded into other

projects. You can attach and combine them in exciting different ways to

create more exotic moving creatures. Try an alternate body like a cork, a

paper box or LEGO bricks.

A good place to start using the components is by creating a small,

self-contained circuit on a LEGO board. If you ﬁrmly attach that board to

your design, or even put it inside, it can shake the whole structure. In the

top photos, a tiny circuit was assembled using copper tape on LEGO bricks.

Try adding a motor and putting the circuit into a paper box to make a mov-

ing creature! You can also embed the circuits on a cork, pins and pipe

cleaners. Take a look at the www.lectrify.it/projects for more ideas!
