We have a shortlist of favorite science crafts like Layers of Atmosphere, Inner Earth Layers, Anatomy of a Volcano, and Layer of the Ocean. This activity is sure to become a new favorite. It comes together fast and is packed with educational insight.

🌼 What Is the Flower Cross Section Model?

This unique 3D flower model shows a cross-sectional view of a flower—meaning kids can see inside the flower and identify each part from the petals to the pistil. It’s designed like a puzzle that kids can build and display. Each anatomical piece clicks into place to form a complete model that stands upright using the included base.

Made from biodegradable, non-toxic PLA right here in the USA, it’s safe for kids and better for the planet. Plus, it comes with a free black-and-white worksheet you can print and color for extended learning!

It’s great for:

• Visual learners who love building and seeing how things fit together.

• Kids studying Botany, Flowers, or Science.

• Homeschoolers and teachers needing hands-on activities for science units.

• Gifted kids who enjoy tactile puzzles with an educational twist.

  
  

  

  
  

🧠 What Kids Will Learn

This model covers the main parts of a flower that are typically taught in early elementary and upper grades:

• Petals

• Stamens (Anther + Filament)

• Pistil (Stigma, Style, Ovary, Ovules)

• Sepals

• Reproductive process of flowering plants

  
  

It’s perfect for 1st–5th grade, and it’s also a great visual aid for older learners studying plant biology.

✂️ How to Build the Flower Cross Section – Step-by-Step

• Materials included:

  • 3D printed flower model pieces

  • Display base

  • Instruction sheet

  You’ll need:

  • Your hands and a flat surface

  • Optional: worksheet and crayons/markers for extended learning

  Instructions:

  1. Lay out all the pieces – Start by placing all flower parts in front of you. Identify each part using the info sheet.

  2. Start from the bottom – Begin with the green sepal/base piece. This supports the entire flower.

  3. Add the ovary and ovules sticker – attach the ovary sticker into place above the sepal. The swirl design inside shows the future seeds.

4. Attach the style and stigma – Stack the style on top of the ovary, then press the sticky stigma into place at the top.

   
   

5. Insert the stamens – Slide the filament pieces (the yellow stems) around the pistil. Then press the anthers onto the ends.

6. Add the petals – Snap the red petals around the center to complete the flower.

7. Place it on the stand – Once all pieces are securely in place, attach the flower to the base for an upright display.

   
   

💡 Tip: Press pieces gently but firmly. If you ever want to remove parts, pull gently.

💡 Fun Facts About Flowers – WOW Your Kids!

• 🌼 The world’s largest flower, Rafflesia arnoldii, can grow over 3 feet wide and smells like rotting meat to attract flies!

• 🦋 Flowers like the passionflower have ten or more floral parts—way more complex than most!

• 🐝 Sunflowers are actually made up of thousands of tiny flowers arranged in a spiral! What we see as one flower is a whole community.

• 🎨 Some flowers change color to tell pollinators they’ve already been visited—nature’s way of saying, “I’m closed for business!”

💡 Tips for Parents and Teachers

🌸 Make it interactive:Turn learning into a fun game! Ask your child questions like:➡️ “Which part of the flower is like a mailbox and catches the pollen?” (Answer: Stigma)➡️ “Which part turns into seeds after pollination?” (Answer: Ovary and ovules)

🧵 Incorporate storytelling:As your child assembles the flower, weave a fun story:🌼 “Imagine a bee flying in for a snack. It brushes past the anthers, collects pollen, and lands on the sticky stigma of another flower. The adventure begins!”This narrative helps reinforce how pollination works in a memorable way.

📚 Connect it to real flowers:After building the model, go outside and find real flowers. Help your child identify the parts on a daisy, lily, or tulip. Ask: “Can you find the sepals on this flower?” or “Where do you think the ovary is hiding?”

🎨 Reinforce through creativity:Encourage your child to draw their own flower, label the parts, or even invent a “new” flower species with silly parts and imaginative functions!

🪴 Keep it on display:Place the finished cross section on a bookshelf or science station. Visuals encourage curiosity! Children love showing off what they've made and often revisit topics when models stay in view.

🔄 Extend the lesson:Use this model to kick off a mini-unit on plant life cycles, seed dispersal, or pollinators. Pair it with a simple seed planting activity so they can observe how flowers grow from the ground up!

💬 Questions to Ask Your Child While Exploring the Flower Model

Keep your child engaged by turning this activity into a fun conversation! Ask open-ended questions to spark curiosity and help them think critically about what they’re building.

Try these while assembling the flower:

• 🌸 “What do you think the petals are for?”(Hint: They attract bees and butterflies!)

• 🌿 “Can you find the part where the seeds grow?”(Look inside the ovary!)

• 🐝 “Why do you think flowers need pollen?”(Talk about how plants make seeds!)

• 🔍 “Which part do you think is the most important?”(Let them choose and explain why!)

• 🧠 “Do all flowers look the same?”(Encourage them to look at real flowers in your yard or local park!)

• 🌱 “What happens to a flower after it’s pollinated?”(Lead into a lesson about fruits and seeds!)
