Go on a nature walk with your children. Bring your digital camera and ask the kids to keep their eyes open for flowers. Photograph them when you come across them.
Upload your flower photos to your computer and then go to a plant identification website in order to figure out what each flower's name is. You can normally search according to color, scent, height, spread and other basic flower characteristics.
Print your flower photos using your printer and help your children to label them with the names you discovered during your flower identification session. Display the photos on the walls in your homeschooling area.
Ask your children to choose their favorite flower, ensure that it can be grown from seed, and then head to your local nursery to purchase the appropriate seeds. If your local nursery does not carry the appropriate seeds, investigate ordering them on the Internet.
Ask your homeschoolers to fill small paper cups with soil-free potting mix and plant the seeds as directed on the seed packet.
Water liberally and place the potted seeds near a window or under a special plant light. Keep well watered and wait for the seedlings to reach 2 inches in height.
Spend an afternoon transplanting the seedlings into larger gardening pots or into the soil in your outdoor flower garden.
Draw pictures of the mature flowers with your children once the plants are mature. You can take photos of the mature plants to use as guides or sit outside near them with crayons and paper in hand.
