Cut the top half off of one empty milk carton for each child. Supply soil, flower seeds and spoons. Scholastic suggests using zinnia seeds, since these flowers will attract butterflies when they're moved outside. Demonstrate how to fill the carton with soil, place a few seeds in then add more soil. Children must plant and water their flowers as well as choose a sunny location where they will grow. Each day, children can care for their flowers and observe their growth.
Peel the backing off of one sheet of contact paper and place it sticky side up in front of each child. Let children choose several flower blooms and place them onto the contact paper. Provide strips of tissue paper and craft supplies such as glitter and string. Children can decorate the contact paper with these items. Peel the backing off another piece of contact paper and press it down onto the first sheet. Hang them in the classroom.
Print small pictures of several varieties of flowers, making two cards for each flower. Cut each picture into equal size squares and laminate them. These cards can be used in several ways. First, as flash cards to teach children the name of each flower. You also can give a stack to the children for counting as well as sorting based on color, size or the first letter of the flower's name. For even more fun, put the cards face down on the floor and have the children match up the pairs, testing their memories.
Take children on a walk to a park or garden. Bring along magnifying glasses and paper and crayons. Children can examine varieties of flowers and draw illustrations of flowers and the insects they attract. Ask the children to smell flowers and describe their scents. This exercise requires children to practice making observations and comparisons. Bring along a camera and take photos that can be used to decorate your classroom or make collages.
