Preschool students love to observe their environment. Invite them to discover how seeds grow and develop into plants with this class project-based lesson.
Students will be able to identify the process of growth and development from a seed to a plant.
Introduction (10 minutes)
- Ask the students to come together as a group.
- Ask students to identify where plants come from and what plants need to grow.
- In one hand, show students a live plant, and in the other hand, show students a few seeds.
- Tell students that today they will be learning how seeds grow and develop into plants with the help of soil, water, sunshine, and carbon dioxide.
Explicit Instruction/Teacher Modeling (10 minutes)
- Inform students that all plants start off as a seed and that all seeds have life in them, and they need energy and food to form a plant.
- Inform the students that a seed will not grow if they hold it on their heads or place it on the table.
- Tell your students that the main items needed to trigger a seed to grow are soil, water, sunshine, and carbon dioxide.
- Watch the Lima Bean Time Lapse video.
- Explain to your students that it took the video creator 6 days to make the video.
- Inform your students that today they will start their own class projects, and in about 6 days they should have their own plants.
Guided Practice/Interactive Modeling (10 minutes)
- Provide each student with a sheet of newspaper to line their desks.
- Give each student a Lima bean seed, a snack sized sandwich bag containing soil, a clean and dry half pint milk carton, and a 1 ounce cup of water.
- From the front of the classroom, demonstrate how to pour the soil from the bag into the half pint milk carton.
- Have students dig a well in the soil to place the Lima bean seed there.
- Have the students cover the soil over and then water the seed with an ounce of water.
- Instruct the students to place their potted seeds in the window sill where they can get direct sunlight.
- Inform the students that each morning they will water their seeds until they see growth.
- Label the students' seeds so they can take them home at the end of the class project.
Independent Working Time (10 minutes)
- Give each student the How Do Potatoes Grow worksheet and Plant Survival worksheet.
- Read the instructions for both worksheets.
- Provide the students with scissors, glue, and pencils.
- Enrichment: Give the students blank pieces of paper and instruct them to depict the process of growing a seed to a plant by drawing it.
- Support: Give the students partners to assist them with planting their seeds.
Assessment (10 minutes)
- Grade the independent worksheets.
- Give feedback and allow for reinforcement if students did not master the concept.
Review and Closing (10 minutes)
- Ask the students where plants come from, and have your students describe the process of seed formation.
- Take responses by raised hands.
