Air column: space within the percussion instrument that determines the pitch. Percussion: sounds produced by striking the instrument with a mallet or stick, or striking one instrument against another. 2. Review the process of forming a hypothesis and making a prediction.
Dig short, shallow rows. The rows should be no more than 1/2 inch (1.5 centimeters) deep and spaced 4 inches (10 centimeters) to 6 inches (15 centimeters) apart. 3. Drop the seeds into the rows. Space the seeds approximately 1 inch (25 millimeters) apart in order to allow the onions enough room to grow and mature.
Sets are defined as onions bulbs that have reached about one inch in diameter. These small bulbs are conditioned to be planted later in gardens. After planting them, they immediately grow to form larger onion bulbs, although sets are sometimes appropriate for growing both bulb onions and green onions.bout half this spacing will allow you to grow green onions. Space the rows about 16 inches apart. If you prefer to grow onions in garden beds instead of rows, give them about seven inches of space on all sides.
