Candy is great for another awesome STEM activity for kids. Make your own gears at home or in the classroom with candy corn for a Halloween twist. Explore how gears work while you test out your engineering skills.
HOW TO MAKE GEARS OUT OF CANDY
HOW DO GEARS WORK?
Gears are circles that have teeth, or cogs, around their edges. The cogs of each gear fit into the cogs of another. The gears and cogs work together to make things move.
Gears are simple machines that control force. There are examples of gears all around us! Bicycles, watches, cars, factory equipment are all examples of machines that use gears.
What direction do gears move? If you watch carefully, you will notice that with two gears, one will move clockwise, and the other will move counter-clockwise.
CANDY GEARS ACTIVITY
- Round plastic lids; different sizes are fine.
- Hammer and nail
- Candy corn
STEP 1. Draw a dot in the center of each plastic lid.
STEP 2. Use a hammer and nail to pierce a hole through the dot in the lid.
STEP 3. Push a brad through hole in each lid. Make sure the lids can turn freely around each brad.
STEP 4. Glue the candy corn around the outside of each lid, making sure to space them evenly to make your gears.
STEP 5. Attach your gears to a piece of cardboard using the brads. Place the larger gear to the left of the smaller one so one candy corn cog of the smaller gear is between two cogs of the larger gear.
What do you think will happen when you turn one of the gears? Which gear turns the fastest? What direction do the gears turn?
