Reproduction of Flowering Plant: Pollination -> Fertilisation -> Seed Dispersal -> Germination Himalayan Balsam plant dispersing it seeds by exploding, sending the seeds up to 23 feet away The Balsam fruit has a pod-like structure with seeds that are quite light. The seeds are dispersed by splitting action or otherwise known as explosive action. Such structural adaptation helps to disperse the seeds far away from the parent plant Seed dispersal can help to prevent overcrowding and reduce the competition between the young and adult plant for water, space, nutrients and sunlight.

After Science CA1, we looked through and analysed the papers of the students and there are some mistakes that most students get it wrong over and over again in PSLE science across all P4, P5, P6 students.  We have decided to share them with you and may the mistake / misconception get recified once and for all.  PSLE A* Science for the win! For a better view of the questions and answers, you may download the document here . Feel free to post your questions to us if you have any. :) Common Mistake 1 Topic: Matter (Primary4 Science) Qns: An air pump is used to pump air into a tank through an inlet as shown below. The  tank  and  air pump  have a capacity of  500cm³  and  150cm³  respectively. Kaizer added  200cm³ of water  into the tank.  He then pushed the plunger of the air pump 5 times. What is the  volume of air in the tank  now? Mistake: 750cm³ Misconc...

The weather has been rather warm recently with no sign of rain for many days. Science coaches LiSu and LeeXian decided to make some ice cream within a few minutes using the concept of impurities (Topic: PSLE Science Water Cycle).
