How to Grow Beans for a Science Project

Overview

Science projects teach students how things work by providing them the opportunity to view cause and effect. Many science projects revolve around the study of plants. Science projects involving plant growth require specimens that reach maturity within a short time, creating an opportunity to examine all stages of growth. You can grow a bean sprout in a jar for a science project. Using a clear container exposes all sections of the plant, including the roots, for observation and study.

Step 1

Select a few bean seeds to grow. Purchase bean seeds intended for planting from a gardening store or use raw, unprocessed beans sold in grocery stores. Avoid cooked and freeze-dried varieties. Look for beans that are uniform in shape and undamaged. Choose three or four bean seeds to use in your science project.

Step 2

Find a jar or other clear container for planting your bean seeds. Place some small pebbles at the bottom of the jar to provide drainage. Fill jar with potting soil to a level just below the rim. Lay the beans on the surface of the soil and gently poke into the soil. Follow directions on your seed package for depth of planting or insert to a depth of two to three times the size of the bean. Water the soil until slightly moist. Place the jar in a warm, sunny window. Keep the soil slightly moist as the beans sprout and grow. Do not over-water your beans. Thin out all but the strongest bean sprout after the first leaves appear on the sprouts.

Step 3

Keep a record of all stages of bean growth for your science project. Write down the initial planting procedures. Include regular observations, keeping record of dates and length of time from planting. Include photographs or small sketches to enhance your written record. Include observations of the root system as it appears near the inside edges of the jar. Measure the plant's growth periodically and include these measurements in your written record.
