In our first activity the kids gathered flowers from our yard. Then they had to determine whether the plants were monocots or dicots by counting the number of flower petals. Flowers with multiples of three petals are monocots. Flowers with multiple petals of four or five are dicots. (The other day we did an activity looking at the leaves. Monocots have parallel veins in their leaves while dicots have netted veins (like a maple leaf.))
Here are some of our previous garden science activities.
