The document describes a class of 9-year-old students who studied almond trees. In December, they observed a bare almond tree with no leaves, flowers, or fruits. In February, they returned and saw the same tree covered in flowers. They drew a picture of the flowering tree. In May, they returned again and saw the tree with almonds, which they drew a picture of. They learned that in the heat, farmers will harvest the almonds that they will use to make nougat for Christmas.
