Fun Crafts For Your Child’s Science Fair Project

by Emma W.R. on September 2, 2015

If your son/daughter is looking for a fun Science Fair idea then why not introduce them to the classics! You can’t go wrong with a model Volcano or the Potato Powered Clock. Science Fairs are not just about winning awards and ribbons- help your child develop a passion and enthusiasm for learning and being creative.

Volcano

VOLCANO

What you need:

  • Container (soda can, Mason jar, plastic bottle, etc.)
  • modeling clay
  • vinegar
  • 1 tablespoon of dish soap
  • red food coloring
  • 2 tablespoons of baking soda
  • 1 sheet of paper towel
  • 1 rubber band
  • Paint and a paint brush

Follow these steps:

  • Use the modeling clay to form the volcano around the container
  • Decorate the outside of the volcano using the paint
  • Allow the clay to sit for one hour or until it is dry
  • In a separate bowl, mix your vinegar with a few drops of red food coloring and a tablespoon of dish soap
  • Pour the mixture into the volcano
  • Roll your baking soda up in the sheet of paper towel. Keep the paper towel from opening by using the rubber band
  • When ready, drop the baking soda roll into the volcano. Once the paper towel dissolves, your volcano will explode!

 

Potato Powered Clock

Potato Powered Clock

What you need:

  • Two potatoes
  • Two short pieces of heavy copper wire
  • Two galvanized nails
  • Three alligator clips
  • One simple low-voltage LED clock that functions from a 1 to 2-volt button-type battery

Follow these steps:

  • Remove the battery from the clock (pay attention to which way the positive [+] and negative [-] points of the battery faced)
  • Number the potatoes as one and two
  • Insert one nail in each potato
  • Insert one short piece of the copper wire into each potato as far away from the nail as possible
  • Use on alligator clip to connect the copper wire in potato number one to the positive side of the clock’s battery compartment
  • Use one alligator clip to connect the nail in potato number two to the negative side of the clock’s battery compartment
  • Use the third alligator clip to connect the nail in potato one to the copper wire in potato two
  • Set your clock to the correct time

Never heard of the potato powered clock but I think my nephew would love trying this! I’m going to set this up for the next time he comes over – thanks for the idea!

I haven’t done a science experiment in years and am waiting on the opportunity where my son will be doing one. I think he is going to pick something hard but I am hoping for the volcano eruption.

This is really cool. I definitely have to try this on a cold snowy day with my family, just to do something different.

I dread science fair time of year. Thank you for reminding me that we don’t always have to scour the internet for new ideas – who doesn’t want to watch a volcano explode??

Definitely sending these ideas to my grandchildren, simple to do and with a little help from mom or dad.
