There is a lot more to flowers than just a pretty scent and beautiful colors. Some scientists spend their entire careers studying just a few varieties of flowers. Botany, the study of plants, is all about learning everything there is to know about flowers. If your kids are flower lovers, then they will love making this 3D parts of a flower model.
Our inspiration for this hands-on STEM activity was the lovely rose. My kids love roses, but they didn’t know much about the parts of a rose before this activity. After researching roses and building their very own 3D roses, they are now experts on all things roses. Use this and the other resources listed at the bottom of this post to complete a wildflower thematic unit for older kids! It’s the perfect addition to your spring STEM activities!
Parts of a Flower Model: How to Make a 3D Rose
The goal of this biology challenge was to see if my kids could recreate a flower as closely as possible. We used everyday supplies, listed below:

First, we spent some time researching wild roses.
Next, the kids studied pictures of roses to determine the parts they needed to recreate with their paper rose.
The petals, leaves, and sepals were made from paper. The stem was a drinking straw. The roots, soil, and filaments were made from play dough.
The kids used hot glue to stick the parts of their flower together. We like to use hot glue because it dries almost instantly and makes it easier to build 3D shapes.
After the flower was complete, the girls compared it with pictures of real wild roses to see how close they got to the real design. Other than wild roses having a more open petal shape, the rose looks pretty accurate!
The Science of Wild Roses
What we found researching the parts of a flower and a rose is that there are very few wild roses left in the world. However, Texas, our home state, is home to one of the last strains of uncultivated rose, called rosa blanda. This rose is a more open-face rose than what we traditionally think of when we picture roses, but it is a bright pink rose with a wide open center and five distinct petals.
The rose my kids ended up making is similar to roas balnda, but not an exact replica as they put too many petals on their rose.
