Homeschool Science Project: Treasure Maps and Invisible Ink

Leave a comment

Home School Science Project — Creating a Treasure Map With Lemon Juice?!  Here’s how we did it, our source, and items needed.  I hope you and your home school kids (or traditionally schooled kids) enjoy doing this project as much as we did.  :  )

How We Did It–

*My daughter Nixi and I made our maps according to instructions in the book **(see instructions at bottom of this post), then we gathered up some odds and ends…sparkly treasure, bundled it up in a paper towel, and buried it out in our yard where ‘X’ marks the spot on our maps.  I spray painted an X where we buried our treasure, and when my husband (Daddy) got home from work, he and Nixi hunted the treasure.

It was quite a kick, and I would definitely recommend this learning adventure to everyone who has kids or grand-kids; even nieces or nephews.  Heck..! Gather up the neighborhood kids and make a party out of it. The more the merrier!  :  )


We Checked Out This Great Book From Our Local Library

Recipe and Items Needed


Items Needed & Treasure to Bury


Nixi’s Map


Mom’s Map


We Spiced Things Up a Bit by Making One Map a ‘Trick Map’!


You’ll need:

-Paper (We used Resume Stock Paper)

-Lemon Juice, Cotton ‘Swab’ (Get it…?!  Swab!  hahaha)

-Treasure to Bury

-Spray Paint or Crafty ‘X’ to Mark the Spot

-Oven…heated to 400 degrees

Juice your lemon, then dip your cotton swab in the lemon juice, then ‘paint’ your map.  Steady as she goes, since the ink disappears rather quickly.  Place your map onto a cookie sheet and place in a 400 degree preheated oven for 30 minutes.  Careful when you take it out, it’ll be hot!  Gather your treasure, bury it, mark the spot with an X, and let your littlest Pirates (or the bigger scally-wags) hunt for the treasure.  Fun all around!

Just a Vagabond who chooses not to fit into societal measures. I strive to live a simple life, below my means....somewhere out there, preferably Off the Grid. My choice of lifestyle and the way my family and I live has often labeled us 'Gypsies', which in-part was the inspiration behind Gypsy Vin Rose -- my artist' name. I write, compose, and perform all original songs about mine and my family's experiences out there on the in to Wanderlust. Hear my newest works at When I'm not writing new songs, I write books -- women's fiction, children's name it! My last released book was Monday...Super-Fun Day; which teaches the days of the week to young readers. It was my first (and most rewarding) effort at illustrating in watercolors, and my debut children's picture book. I am currently working on my second women's fiction novel, as well as another children's book. Order copies of my written works at, Barnes & Noble, or where ever quality books are sold. Follow links from my author page at At this writing, I am between the restoration of my antique sailing vessel, Mystic Mermaid; a 68 Morgan 30, and the ongoing upkeep and restoration of my hip gypsy bus. I invite you to join me as I strive to learn from my failures as well as my successes. After all...the journey is always the best part. May you find your path in life, as I always seek to do. Blessings and .V.. (Peace) Gypsy
