POSSIBLE SOLUTIONS

• Make a dance pad.
• Make a light-up card.
• Make a flashlight.
• Make a music card.

BEST SOLUTION

The best solution was to make a light-up card, since we didn't have enough materials for the other options.

CONSTRUCT A PROTOTYPE

TEST AND EVALUATE
WHEN WE TESTED OUR CARD, WE FOUND OUT THAT THE BATTERIES CAUSED OUR LED LIGHTS TO BURN OUT, SO WE HAD TO THINK OF ANOTHER THING.

PRESENT SOLUTION

Now we had 1 solution, which was the recordable musical card.

REDESIGN

• First we bought 2 recordable cards.
• We used them as an example.
• Then we made 2 musical cards.

MATERIALS 1

• 2 recordable cards.
• 2 batteries.
• 1/2 roll wire.
• 4 construction papers.
• Wire strippers.

MATERIALS 2

• scissors
• electrical tape
• gluestick
• stapler
• 2 LED lights
