Hey everyone! Happy Diwali!!!
This month, our preschoolers through second graders, just completed their first project of 2017 – 18 year! We made our own Coloring WiggleBots. Now you can too:
- Disposable Plastic Cup (preferably the larger ones)
- 3 Markers (same size)
- 2 AAA Batteries
- 2 AAA Battery Holder
- 1.5 – 3V DC Motor
- Electrical Tape
- Decorating Supplies (Googly Eyes, Pipe Cleaners, Sharpies)
- Hot Glue (optional)
- Construction Paper
- Glue or tape the three markers on the outside of the cup with the caps sticking out. Make sure the cup can stand on the three legs without any extra support.
- Now make the circuit. Attach the red and black wires to the two leads on the motor. Things to keeps in mind:
- Motors do not have polarity.
- Twist the wire ends on carefully because motor leads can easily break.
- Make sure you put the batteries in AFTER the circuit is connected to see if the circuit works.
- Remove the batteries. Using tape, mount the battery holder and motor onto the top of the cup. The motor should be in the center and the bottom must have direct contact to the cup. It should be flat.
- Cut a circle of the cardboard. Using the nail make a hole in the center of the circle. The cardboard should fit tightly through the motor’s pin without the cardboard moving by itself. (Hot glue can be used to firmly keep the cardboard in place)
- Decorate…Make sure you don’t forget to name it
- Take off the caps and place the WiggleBot onto a piece of construction paper. Put the batteries in.
VOILA! Your WiggleBot is drawing and coloring on its own!!!
How It Works
The battery powers the coils inside of the motor to start spinning. This in return causes the pin of the motor to spin. The motor vibrates and the contact with the cup causes the cup to vibrate, as well. The extra weight on the motor (the piece of cardboard) will make the bot unbalanced, making it move and COLOR.
We had so much fun doing this activity! The activity was able to be finished in a class of 10 kids within 40 minutes. The little entrepreneurs learned about motors and simple circuits. They applied the skills they learned into a fun activity in which they made something really COOL. Check back to see the AMAZING activities we do at GGKLI’s Innovation and Entrepreneurship Club.
