If you want more Geronimo Stilton activities for the series of Geronimo Stilton books, you’ll love this edible spine hands-on history activity. Also I have this Human Body Crafts page for more fun ideas.

Jumping back in time with Geronimo Stilton, he is up to another fa-mouse-ly adventure in the book The Race Against Time (Geronimo Stilton Journey Through Time #3).

The book is divided into three sections of adventure mixed with history; we focused on the second section of the book which is the Renaissance period.

And the ultimate renaissance man is Leonardo Da Vinci known for his time spent learning about science.

First, you’ll love knowing more about the book The Race Against Time (Geronimo Stilton Journey Through Time #3).

The Journey Through Time series of Geronimo Stilton books give so much information on a time period in such an engaging way.

The series has colorful illustrations and text, small snippets of information, and great adventure.

Before the journey begins, we see renaissance fashions and what the time period was about.

And then go right into visiting important landmarks of the time period all through the eyes of a mouse.

You will be introduced to Gutenberg and his printing press.

In addition, your child will read about and Leonardo Da Vinci. They’ll read about his flying machine, sculptures, and art- including the Mona Mousa. I mean Lisa.

Even though the book does not reference the medical span of Leonardo’s contributions it opens the door to talk and research the other things he worked on besides art and inventions.

It becomes a natural springboard to add some science to your book or unit study.

Leonardo Da Vinci Activities

Leonardo da Vinci spent a lot of time measuring and drawing the human body and discovered that it has standard proportions.

He participated in many dissections to learn how the body worked and drew exact anatomical studies. He studied, measured, drew, and went hands-on in every aspect of his quest for knowledge.

This is a wonderful way to introduce younger children to his discoveries and contributions to the science world, particularly the anatomy of the human body.

If your child is interested in anatomy, include this hands-on activity alongside your Geronimo Stilton Unit.

The human body is wonderful. And it is so amazingly designed with the way each part fits together and works to move, protect, and shape our body.

The spine is a perfect example of that, and your science loving child is sure to enjoy making their own spine

Human Body Spine Facts

Look at some of these human body spine facts you can use in talking about Leonardo da Vinci or to add to your Geronimo Stilton activities.

  • The brain connects to the spine to control most basic functions of the body.
  • The spine has three jobs – protect your spinal cord, allow you to move and bend, and provide a foundation for your posture.
  • You have 25 bones making up your spine known as vertebrae
  • There are 7 vertebrae that make up your neck. Did you know that giraffes with their super long necks also only have 7?
  • Some snakes have more than 400 vertebrae.
  • The 5 bottom vertebrae between the ages of 18 and 30 become fused together to make your coccyx, or tailbone.
  • There are over 120 muscles and 220 ligaments that support the average spine.
The Race Against Time Geronimo Stilton Activities: Fun Edible Spine

As you build your spine you can naturally work in the importance of each part that makes up your spine and spinal cord.

  • The spinal cord works with the brain to form the central nervous system.
  • The vertebrae themselves give structure and protect the spinal cord.
  • Intervertebral discs cushion and protect the nerves from wear and tear.
  • The nerve clusters communicate with the rest of our body, sending signals to our hands, legs, feet, arms, head, etc.

Search Google for images of da Vinci spine drawings for a model to help your child along.

How to Make an Edible Spine

Now on to making a delicious, hands-on spine model. You can make yours true to size or create a mini model.

Our model here does not have all the nerves and is not life sized, but we made sure to include 25 vertebrae. If you are doing a unit on anatomy that is one thing you want your children to remember.

Here is what you will need to create your own edible spine:

  • Yarn- Spinal Cord, nerves (ok, not edible, but you know)
  • Butter Cookies with a hole- vertebrae
  • Gummy Lifesavers- intervertebral disc
The Race Against Time Geronimo Stilton Activities: Fun Edible Spine

String a long piece of yarn through a cookie and knot it several times until it is too large to fit through the hole. The yarn is our spinal cord.

The Race Against Time Geronimo Stilton Activities: Fun Edible Spine

Cut yarn into two-inch pieces and twist two of them so that they are between each gummy lifesaver and cookie to create the nerve clusters.

The Race Against Time Geronimo Stilton Activities: Fun Edible Spine

Add on a cookie to create a vertebrae.

Continue repeating gummy, nerve, cookie until you have made your spine as long as you want it to be then tie it off at the top.

I have a fun stem build a Da Vinci parachute activity. Also, look at my unit study and lapbook Renaissance 1300 to 1600.

This year I’ve developed a whole year of STEM activities to go along with our science standards.

We study a new inventor each month. This month it was Leonardo Da Vinci!

Studying about Leonardo da Vinci can combine two subjects kids usually don’t consider as similar: art and science.

When you can tie the arts, engineering, math, and science into a project; you’ll have kids who are going to be able to creatively solve problems their whole life.

Combining many different facets of learning keeps kids engaged and focused in their schoolwork.

When kids begin to understand there is a creative aspect to science, they become more interested and excited to dive into deeper science concepts.

These activities are perfect to use with a Leonardo da Vinci study. You can combine them with an art study, and have a whole Leonardo da Vinci unit!

I chose to build and test da Vinci’s parachute. After studying his sketches, we used math concepts such as perimeter and isosceles triangle constructions.

This also uses physical science such as gravity, mass, and air resistance.

Da Vinci Parachute STEM Activity

What You’ll Need:

  • 1 piece of graph paper
  • Four ⅛ inch dowel rods; 12 inches long (Don’t pre cut these)
  • Four ⅛ inch dowel rods; 16 inches long (Don’t pre cut these)
  • 4 pieces of string; 18 inches long
  • masking tape
  • thin paper for the covering
  • 5 paper clips per parachute
  • ruler

We began this project by doing a bit of research on Da Vinci as an inventor. We researched his sketches and found out many of his sketches were ideas of inventions that we use today.

Then we began the project.

Making a Hands-On Da Vinci Parachute

The first step was to sketch out the blueprints. To get in a little math, I gave the kids the following problem to solve:

The square base of the pyramid will be 144 sq feet. Each square represents 2 inches. How many inches will each side of the base be? Draw it out on your graph paper.

After checking to see if the kids had drawn a 12 x 12 square, it was time to cut the dowel rods into 4 12” pieces.

Da Vinci Parachute Activity

You may need to use craft scissors to cut through the dowel rods.

Next, we used as little masking tape as possible to connect the 4 dowel rods into a square base.

Make a Da Vinci Parachute

Then it was on to the triangular sides.

By presenting another math problem, the kids were able to find out how long the isosceles triangle had to be. Here’s the math problem:

Renaissance Inventor Da Vinci Parachute

The total perimeter of the isosceles triangular sides is 44”. Since we already know the base is 12”, what will be the length of the other sides?

To solve the problem the kids had to subtract 44 from 12 to get 32.

Then they would divide 32 by 2 to get 16. The triangular sides will be 16” long.

The remaining dowel rods should be cut to provide 4 16” rods. These rods are then carefully taped onto the base of the parachute.

When the triangle pieces are all taped together and lying flat, it’s time to cover the sides of the parachute with very light paper.

To do this, we traced around the outside of the triangles and then used as little tape as possible to attach the paper.

Making a Da Vinci Parachute

Then it was time for the strings. This was the hardest part. You must cut four 18” strings.

To keep them from getting tangled, tie all 4 strings together at one end and then make a little loop and tape up each individual string at the other end.

You will then loop a paper clip through each loop. Use one more paper clip at the top of the strings, to connect all of the strings to the top of the parachute. The strings should be hanging down the middle of the parachute.

Model of Leonardo’s Parachute

Constructing a Paper Parachute

To test out our design, we connected each individual string onto a washer.

We used the school playground castle to drop our parachute and to see how long it would hang in the air. We tested different weights to see how we could achieve the longest hang time.

Launching a Da Vinci Parachute

Here’s a recap of the project:

Step 1: Cut and tape together 4 12” dowel rods to form a square.

Step 2: Cut and tape onto the square 4 16” dowel rods to form 2 isosceles triangles. Lay flat.

Step 3: Trace the triangles with light paper to cover the parachute. Use tape to attach the paper

Step 4: Cut 4 18” pieces of string and tie together at one end. Then make a small loop at the end of each string and use a little tape to keep the loop.

Step 5: Attach a paperclip to each loop and and one at the top where the strings are tied together. Use that paper clip to attach the strings to the middle of the parachute.

Step 6: Attach a washer to the 4 paper clips and then find a spot to test your parachute.

This was a highly engaging activity that my kids loved. They learned a lot about Leonardo Da Vinci, a lot about mass, gravity, and air resistance, balance, and a little about perimeter and shapes.

I’m so glad that we took on the challenge of designing Da Vinci’s parachute!

Middle Ages Hands-on History: Make a Codex Activity

Written by Selena of Look! We’re Learning!

I am a huge bookworm. HUGE. If I was left alone on a desert island with a choice between food or books, I’d have to make myself choose the food. That’s just how much I love to read.

As we started studying the Middle Ages, we learned a lot about the beginning of the publishing industry, to which what we owe our modern-day books. It turns out that present-day paper books began with the invention of the codex, the first truly portable written document.

After finding out how codices were made in the Middle Ages, we decided to make one of our own!

Middle Ages History: Make a Codex Activity

The codex was actually invented during the Roman Empire, centuries before the Middle Ages began. Prior to its creation, most important documents, such as literature, speeches, and journals, were kept on scrolls or pieces of parchment.

Since these methods were so bulky, something more convenient was needed, especially for documents that needed to be transported across long distances. Some historians say that Julius Caesar was the first person to develop the idea of a notebook of folded and bound pages, but there is some uncertainty about this.

Either way, the codex (folding pages into small packets and then sewing them into a bound book) quickly became the standard for publishing and distributing literature. In fact, if you look behind the spine of a thick book, you’ll see the individual packets of paper sewn together that make up the book. This is basically a codex in itself.

To make our codex, we decided to focus on a codex from the Middle Ages: The Peterborough Chronicle. This document, which dates back to the 12th century, chronicles the establishment of the British Empire.

Make a Codex Activity Supplies

To make your own codex, you’ll need the following supplies:

  • Pieces of blank unlined paper
  • Yarn needle
  • Seam ripper (or X-Acto knife) *Be sure to use adult supervision when working with sharp objects.*
  • Bulky yarn
  • Ruler
  • Pencil
  • Chisel-point marker
How to Make a Codex with Kids

Begin by folding the pages in half. You’ll want to make several packets of three to four pages. For our codex, we folded six packets of three pages each.

Pricking a Codex Activity

We used a seam ripper to begin punching holes in the first packet. After a few holes, though, we swapped it out for an X-Acto knife, which worked better. If you have an awl, that would probably work even better.

Pricked Codex Pages

We lined up the packets to draw the holes and then punched them in the same spots to make sure the holes would line up for sewing the codex together. Interestingly, when publishers created codices, they also had to make the paper sewing holes by hand. This process was called “pricking”.

Sewing a Codex Activity

Now it’s time to sew the codex together. Thread the yarn through the eye of the yarn needle and insert the needle into the first sewing hole through all the codex packets.

Hands-on Middle Ages History

Sewing a Codex Together

After pulling the needle all the way through, bring the yarn back around and thread the needle through again to secure the first stitch. Then move down to the next pricked hole in the codex.

Stitching a Codex Together

Stitch in this same manner all the way down the side of the codex.

Binding Off a Codex

When you get to the end, pull the yarn back through the last stitch vertically.

Finishing a DIY Codex

Cut the thread to bind off the sewing. Do the same at the top.

Ruling a Codex Page

You’re ready to add writing to your codex now! In the Middle Ages, it was common to line the pages of a codex with ink to make it easier for scribes to write neatly. Just like ruled notebook paper we have today!

Use a ruler and a pencil to draw writing lines on your codex pages. Be sure to leave space for the first letter of the work to be about three lines in length.

Writing On a Codex

Like so. The first page of the Peterborough Chronicle is written in Old English, which looks very different than modern English. Thankfully, the content has been translated. That was the source material for our codex.

Finished Codex Activity

Use a chisel-tip marker to write in your codex and you’re done!

This would be a great extended activity for history! Let the kids find a historical codex and write a paragraph or two from it each day! You could even include pieces from several codices and let the kids discover the kinds of content that would have been considered valuable enough to publish in this manner centuries ago.
