Topic: Life Science-­‐ Molecules to Organisms Software: Cyber Science 3D Plant Life Cycle Lesson Overview Like animals, plants also go through life cycles with various stages. While each plant's life cycle is unique, they all have common stages including birth, growth, reproduction, and death. In this lesson, students will learn about the life cycle of a flowering plant. Using Cyber Science 3D, students will observe a seed and a mature flower. Objectives •

Topic: Life Science-­‐ Molecules to Organisms Software: Cyber Science 3D Introduction The teacher will explain that plants, just like animals, go through life cycles with various stages. Plants have some stages in common with animals and some stages that are different. Over the next few days, the students will learn about and observe the life cycle of a flowering plant. Activity – Plant Life Cycle 1. Open the "Dicot Seed Dissection" session in Cyber Science 3D. 2. Click on the “Presenter” mode at the top left corner of the screen. This will display a list of slides along the left side. 3. Follow the presentation: Click on the “Play Slides” button to pause the session at the first slide. When you are ready for the next slide, click the next slide on the list. Follow the directions on each slide and explore at your own pace. 4. Draw and label the parts of a seed on the "Life Cycle of a Flowering Plant" worksheet. 5. At another center, dissect a real seed, noting the parts that you observed in Cyber Science 3D. Also, "plant" a seed that has been soaked overnight in water in the middle of a Ziploc plastic bag with a moist paper towel inside. Tape the bag to a window to get light. 6. Observe the seed's growth over the next two weeks. Measure the growth of the stem and roots. On the provided worksheet, draw your findings in the germinated seed and seedling stages. 7. Open the "Dicot Flower Dissection" session in Cyber Science 3D. 8. Click on the “Presenter” mode at the top left corner of the screen. This will display a list of slides along the left side. 9. Follow the presentation: Click on the “Play Slides” button to pause the session at the first slide. When you are ready for the next slide, click the next slide on the list. Follow the directions on each slide and explore at your own pace. 10. At another center, observe the parts of a real flowering plant (optional) and compare to the virtual flower on Cyber Science 3D. 11. Draw the flowering plant and label its parts on the provided worksheet. Closing
After the students complete their worksheets, they will discuss their findings. They will share their data regarding the growth of the seeds in their experiment. They will discuss the physical appearance of each stage of the plant's life cycle. They will make conclusions about the similarities between plant and animal life cycles. Questions for Discussion 1. Based on your observations, which stages do both plant and animal life cycles have in common? Birth, growth, reproduction, and death Plant Life Cycle 2
