Nia's Market-Stall Journal

1 On May 3, Nia found a bean seed in damp soil beside the stall. It had not sprouted. A tomato plant at the stall was 18 centimeters tall and had yellow flowers. Under a kale leaf, Nia found several tiny butterfly eggs.

2 On May 6, the bean seed had opened, and a green sprout was 4 centimeters tall. The tomato plant was 19 centimeters tall. The butterfly eggs had hatched into tiny caterpillars.

3 On May 10, the bean sprout was 9 centimeters tall. The tomato plant was 21 centimeters tall and had small green tomatoes. One caterpillar was 2 centimeters long and had begun making a chrysalis.

4 On May 14, the bean plant was 14 centimeters tall and had flowers. The tomato plant had red tomatoes with seeds inside. A butterfly had come out of its chrysalis. It laid eggs under a kale leaf. On May 18, the bean plant was 18 centimeters tall and had pods with seeds. The tomato plant had turned brown and was no longer living.
