Unit Outline 1. Collect a variety of cereal and pulses seeds and distribute a mystery seed to each student. Record student guesses. Germinate the seeds in styrofoam trays layered thickly with cotton wool and keep moist. Wait and observe the seeds' germination and growth.
Students can now make new guesses about what plants the seeds are from.
They attempt new guesses about the plant varieties with help from other students, and by asking questions of parents, local farmers, friends, etc. The stronger seedlings are now planted into pots, and placed outside in a sheltered position 8. Growth is observed, recorded in tables for mathematical analysis using graphs. Students by now know their mystery plant variety, and present their projects to the class to share their new knowledge.
