Target has small flowerpots with seeds and dirt in their dollar section. (You take it home and plant it.) I let each of my children choose a flower, and we brought them home and planted the seeds. We talked about what flowers need in order to grow, and after we planted them we looked up information on each flower on the internet so we could learn about when their flowers would start sprouting and what they would look like full grown.
Next, we went to Reiman Gardens, a fantastic indoor and outdoor garden famous for its butterfly garden (and, therefore, has colorful flowers). We checked out all of the flowers, inside and out, and wrote down the names of the flowers we liked best.
Smelling flowers (and talking about which ones smell good, which ones stink, and which ones are the prettiest in their opinions)
We learned a lot, and had a lot of fun as well!
