K-2 Plant Habitats
Section 1: Welcome to the Activity
What do plants need to survive?
Students will plant rice seeds and observe them for 2 weeks to see how different factors (lack of light, air, nutrients, water and space) affect their growth and development. Students will understand that plants need all of these things to survive.
- Observe what happens to plant growth when they do not receive air, water, sunlight, soil or space
- Keep a journal of drawings and/or text showing scientific observations
- Demonstrate that plants need water, air, sunlight, soil and space to survive

Section 3: Background
- Like animals, a plant‘s habitat is the place where it can get air, food, water and space.
- Because plants make their own food through photosynthesis, they need sunlight and nutrients available in their habitat to survive.
- Plants acquire sunlight and air through their leaves. They acquire water and nutrients from the soil through their roots.
- Rice is a plant important to South Carolina because historically it was one of the principal crops produced by farmers in the Coastal Plains. Impoundments created for rice production during this time are now important habitat for migratory birds.
Like animals, plants are dependent on habitats where they can get the things they need to survive. Like animals, plants depend on air, food, water and space to survive. Plants differ from animals, though, in the way they acquire and use their habitat needs. For example, to obtain food, plants must get air, water, sunlight and nutrients.
Plants are defined as multicellular organisms that get their energy through photosynthesis. There are currently estimated to be 400,000 species of plants on earth. In South Carolina, plants range from the tiny foamflowers of the mountains to the majestic live oaks of the coast.
Through photosynthesis, plants use the energy of sunlight to convert water and carbon dioxide into energy. This energy takes the form of the carbohydrate, glucose (sugar). Plants use glucose as energy to grow and build structures such as leaves, flowers and fruits. Glucose not used immediately is converted into starch and carbohydrates, which are stored in the roots, stems and leaves for future use. Some of these roots, stems and leaves are vegetables, such as potatoes, celery and spinach.
Plants get air through pores in their leaves, water through the roots and sunlight through cell structures in the leaves known as chloroplasts. Chloroplasts contain the pigment chlorophyll, which can absorb sunlight (except the green waves of light, which are reflected out and give plant leaves their green coloration). The energy from the sunlight is used to provoke a chemical reaction between carbon dioxide and water to produce glucose and oxygen. The plant uses glucose as energy and the oxygen is released in the atmosphere. This oxygen is then used by animals including humans. This is a simplified explanation of photosynthesis but provides a basic understanding of the concept.
Besides water, air and sunlight, plants also need nutrients and space to survive. Plants draw nutrients, such as potassium and nitrogen, out of the soil through their roots. These nutrients are used in processes such as osmosis regulation or enzyme production. Plants need space so they are not in competition with other plants. If certain plants are too close together, their roots will compete for nutrients and water and may not survive. Also, larger plants, such as trees, can block sunlight and make it difficult for other plants to grow underneath them.
Rice, the focus of this activity, is an important plant to the cultural and natural history of South Carolina. Rice is a grass that can grow from 2-6 feet tall. Originally, rice flourished in dry climates, but thousands of years of cultivation have led to varieties that do well in water-saturated areas. Today, rice is perhaps the most important crop and provides more calories to humans than any other food. Annually, about 570 million tons of rice is harvested worldwide.
Rice farming began in 1694, and at its peak in 1850 between 100,000 and 150,000 acres of land was being cultivated for rice production. This had both cultural and environmental impacts. The intensive labor required to grow rice encouraged slaveholding, and thus strengthened and increased this practice. Slaves were used to clear forests, drain wetlands and build impoundments for rice fields, and habitats were changed to grow rice.
Impoundments are areas in which earth banks were built to hold water for use in the rice fields. These impoundments use water control devices and drainage ditches to move water. Today about 70,000 acres of impoundments still remain. Though a major alteration of the natural landscape, these impoundments have become important habitat for migrating waterfowl. The South Carolina Aquarium has an exhibit representing the habitat of rice impoundments.
Section 4: Procedures
- Rice seeds (If not available, any plant seed can be used. Rice was chosen because of its importance to South Carolina history)
- Seedling tray
- 6 flower pots
- Potting soil
- Small section of turf or grass that will fit in one of the flower pots
- Vacuum sealer bag (Vacuum packed storage bags found at specialty stores such as Bed, Bath and Beyond or Target). If you don’t have this, do your best to get the air out of a ziplock baggie (can use reverse vacuum).
- Aerated opaque cover (or anything that will keep light out, but allow air in)
- Before activity begins, plant rice seeds in seedling trays until you have 6 seedlings of roughly equal size (can do this with students).
- Explain to students they will be determining what plants need to survive. Set 6 flower pots up in the classroom near a sunny window. Fill 4 with potting soil. Another one will have potting soil with grass growing in it. This can be accomplished either by planting grass seed, or by buying a square of grass turf and cutting it to fit the pot. The last pot will not have soil in it. Each pot will be labeled. The pot with no soil will be labeled “No soil”. The pot with grass will be labeled “No space”. The other four will be labeled “No air”, “No water”, “No sunlight” and “Control”. Each pot will have a seedling placed in it. The ones with soil will have the seedlings transplanted into the soil. The empty pot will have the seedling placed on the bottom. All pots will be watered except the “No Water” pot. After watering, the “No air” pot will be placed in a sealed vacuum bag with the air removed, and the “No light” pot will be placed under an aerated opaque cover. Here’s a quick reference:
Pot #1 = “Control” (soil, water, air, sunlight)
Pot #2 = “No soil” (water, air, sunlight)
Pot #3 = “No water” (soil, air, sunlight)
Pot #4 = “No sunlight” (soil, water, air)
Pot #5 = “No air” (soil, water, sunlight)
Pot #6 = “No space” (grass on top of soil, water, air sunlight)
- Each day, students will water the pots, except the “No water” pot, and observe what is happening in each of them. They will write or draw their observations in a journal. If students are not able to write, the teacher should record the observations in a classroom journal or have students draw their observations in their own journals. They should do this each day with the day labeled. If they see no change, they should write “No change”. For example:
Pot #2 = No soil: no change
Pot #3 = No water: turning brown, leaves wilting
Pot #4 = No sunlight: no change
Pot #5 = No air: no change
Pot #6 = No space: no change
- After 2 weeks, students should compare what happened to the seedlings. The students will review their journals, compare what each plant was receiving or not receiving, what happened to each plant because of this and make guesses about what plants need to survive. The class will discuss the results and consider if their results are true of all plants.
- If we planted rice from a grocery store, would it grow?
- How do plants in the schoolyard get air, food, water, soil and space?
Section 5: Assessment
Give each student a rice seed to plant and have the following items available for students (flower pots, soil, water and window sills with sunlight, vacuum seal bags, opaque aerated bags). Tell students, based on what they have learned, they must make the rice seed grow. Students must determine on their own that they will need to put soil in the flower pot, plant the seed in the soil, place the flower pot in the sunlight and water it regularly. Have students write their response in a journal.
Scoring Rubric out of 100 points
Correctly plant seeds in soil in flower pot: 20 points
Correctly place seeds in sunlight: 20 points
Water seeds regularly: 20 points
Allow seeds to have air and space: 20 points
Successfully have seedling sprout: 20 points
Section 6: Cross-Curricular Extensions
Have students plant oak tree acorns or tulip bulbs to see the similarities in what these plants need to grow.
Have students make and eat rice pudding. Discuss how doing this is meeting one of their own habitat requirements.
Social Studies Extension
Most of the rice plantations in South Carolina were found near the coast. Rice crops need lots of water. Show students a map of South Carolina and point out where rice plantations would have been found. Ask students why the plantations were built where they were.
Language Arts Extension
Have students research and bring in samples of different types of rice that are sold at the grocery store. Use senses to determine how the grocery store rice is different than the rice seeds.
Language Arts Extension
Have students gather rice recipes and create a rice recipe cookbook.
