To further recall the subject matter, it’s better to have an activity that leads them to experience theory in reality like what the Primary 4 students did. Application is very important for they see in actual situation the imaginative ideas that needs to be expressed.
Primary 4 performed celery experiment. This is to prove that water travels or circulates in every part of the plant as human body undergoes in circulatory system. The celery stalks are soaked in the colored water for a day. The next day, the stalks will be cut to see the red spots.
The plants have 2 tubes that play important role in circulation of the food and water: xylem and phloem.
