Every year we plant a garden with the kids, and every year something pops up that we didn’t plant. One summer it was sunflowers. Everywhere.
So we cut a few, put them on a tray and turned them into a hands-on lesson on the parts of a sunflower, with a little tweezer work for fine motor practice.

Harvest
Cut a sunflower just below the head. We picked ours from the garden.
Rinse
Rinse the heads outside to wash off any bugs.
Set up the tray
Put the heads on a tray with tweezers and small bowls.
Pluck and count
Use tweezers to pull out seeds and count them. Dried heads are easier for little hands.
Slice it open
An adult cuts the head in half with a serrated knife so kids can see the receptacle and the inside.
Tip
Our sunflowers didn’t have mature seeds yet, which made plucking tricky. Next time we’ll use dried heads. Unopened buds are fun to dissect too.
Sunflower Facts for Kids
- It’s many flowers in one. The dark center is made of hundreds to thousands of tiny flowers called disc florets.
- Bees love them. Once the disc florets are pollinated, they become seeds.
- The yellow “petals” are ray florets. They’re flowers too.
- The receptacle is the base of the head that holds it all together.
