Objectives 1) Students will learn that flowers have essentially four parts. 2) Students will learn both the male and female reproductive parts of the flower. 3) Students will learn about self-pollination and pollination by insects and other animals. Equipment and Materials Petri dishes Lily plants Dissecting kits Geranium plants Scotch tape Gladiola plants Magnifying glasses Apples Saran wrap Spices Construction paper Fruits Overhead projector Nuts Prepared transparency Olives Prepared worksheets Honey Silk scarf Indigo Pictures Recommended Strategies Display flowers, scarf, pictures and edible items at front of the classroom. (Phenomenological Approach) - Students will answer questions about the flowers, honey, dye, pictures, etc. Example: What do you notice? Possible answers: flowers, fruit, colors, etc. Show picture of bee pollinating flower. Ask: What do you know about bees and flowers? Possible answers: Bees make honey, insects pollinate flowers. Students will use handouts to identify the parts of a flower and the sub-parts. Demonstrate the parts that are male and female by use of the overhead projector. Use a transparency of flower diagram. Use a sample flower (lily) to show the studied parts. Pass the lily around the classroom for each student to see. Students will show knowledge of the parts of a flower by dissecting a lily and/or a gladiola. They will affix each part on a prepared sheet and label the parts. Show picture of apple flower and cross-section of an apple. Teacher will cut an apple in half and show the remnants of the pistil. Teacher will cut the apple crosswise to show the ovules. (eggs) Students will eat products of the flower: seeds, nuts, raisins, etc. Students will observe the cut apple and cross-section and then eat the parts. Students will color labeled sheets for take-home or bulletin board display. Students will place dissected plant sheet on construction paper for bulletin board or take-home. Optional Dissect pollen tubes and count number of pollen grains. Calculate length of time it takes pollen to travel down the tube using worksheet suggested from United Graphics.
