Primary 5 : Dissecting Seeds
Most plants begin life as seeds. A seed is the part of a flowering plant that can grow into a new plant. There are many different kinds of seeds. Some plants make a lot of seeds; some make only a few. Seeds are often hard and very small, but some are larger.
Previously, P5 students observed and identified that seeds come in many shapes, sizes, and seed coat types. Then, they learned seed structure by dissecting it. Students were given five kinds of overnight soaked seeds and dry seeds. The seeds were green beans, red beans, soybean, black soybean, and peanut.
First, they had to identify and compare the differences between overnight soaked and dry seeds. Then, they dissected the overnight soaked seeds to identify and observe the structure. Students were challenged to dissect the dry seeds and check the inside. They found that dry seeds were hard and difficult to dissect, whereas overnight soaked seeds were easier since they were swollen and soft.
Based on the experiment, students concluded that:
- Seeds have different colors of the seed coat.
- Seeds have the same seed structure: seed coat, baby plant/embryo, and food storage.
P5 students enjoyed the activities and could share their observations and conclusions. **
