Brief Description
Students grow sprouts from seeds using soil in clear plastic bags.
Objectives
Students
- define the word greenhouse,
- learn general information about common sprouts,
- plant sprout seeds in soil inside clear plastic bags,
- monitor and record each sprout's growth.
Keywords
herbs, greenhouse, plastic bag, seeds
Materials Needed
- packets of three different sprout seeds; for example, alfalfa, broccoli, radish, sunflower
- quart-sized plastic bags that zip at the top, one per group (if available, use the kind that have a designated area for label)
- soil
- permanent marker
- self-adhesive label or masking tape (optional)
- water
- paper plates (one per group)
- ruler
- paper
- pens or pencils
Lesson Plan
Prior to the lesson, soak the seeds for 8 to 12 hours in a volume of water that is double or greater than the amount of seeds. Rinse before planting.
- Discuss the meaning of the word greenhouse. Tell students that they are going to create very simple greenhouses using plastic bags, soil, and water.
- Show students the soaked seeds. Explain that students will use the seeds to grow sprouts like the kinds people often eat in salads or on sandwiches.
- Divide the class into pairs. Distribute some of two types of the soaked seeds, one plastic bag, soil, and a paper plate to each pair. Give students these instructions:
- Write the names of the seeds you will plant and your names on the bag (or on the label or tape).
- Place about an inch layer of soil in the bottom of the bag.
- Put the seeds in the soil.
- Add water, but do not drown the seeds.
- Place the bag on the paper plate.
- Leave the bag partially open to allow air inside and to keep some moisture inside the bag.
- Check the bag each day for moisture and growth. Measure plants daily using a ruler.
- Put the plates in one spot in the classroom. Have students monitor and record the growth for five days. Have each group report their findings to the class.
Extension: Have students put the sprouts in pots and continue monitoring until the sprouts become plants.
Variations:
- Compare growth by putting some bags near a window and others in a dark spot in the classroom.
- Try the activity using other kinds of seeds, such as herb seeds.
Assessment
Evaluate students' participation and reports.
