Introduction: LEGO + Flowers = Fun Learning!
Looking for a creative way to teach your children about plants while keeping them engaged? This LEGO flower building activity is perfect for home education, preschool play, or a rainy afternoon. We used LEGO bricks to explore the parts of a flower — stem, leaves, petals, and seeds — and created a range of simple, colourful flower designs.
Plus, I’ve included a free printable worksheet so your little builders can follow along and design their own LEGO flowers at home.
Learning Benefits of LEGO Flower Building
This activity isn’t just fun — it’s packed with early years learning opportunities:
Science – Learn the parts of a flower and their functions.
Fine motor skills – Click, stack, and adjust LEGO bricks to strengthen hand muscles.
Creativity – Encourage original designs beyond the examples.
Problem-solving – Work out how to balance petals, build height, and keep flowers sturdy.
Early maths – Count bricks, compare heights, and talk about symmetry.
What You’ll Need
LEGO or DUPLO bricks (mix of basic colours and shapes)
A flat building base (optional)

Step-by-Step LEGO Flower Activity
Step 1 – Talk About Real Flowers Show a real flower or look at the diagram. Discuss the stem, leaves, petals, and seeds. Point out each part.
Step 2 – Look at the Worksheet it includes labelled flower parts and a colour key, if you want separate colours for separate elements, some easy model ideas to begin.
Step 3 – Build Together My son started with the stem/leaves then added the flowers, and you can get creative maybe adding roots we made little bees and a mini flower life cycle.
Step 4 – Create Variations Challenge your children depending on age/skill level to build:
The tallest flower possible
A flower with a high number of petals
A “fantasy flower” with unusual colours or shapes
Step 5 – Display & Discuss Put the flowers on display, talk about each design, and take a photo for your home education portfolio.
