PSLE Science Academic Coaching

It was 28 September when I announced that it's public holiday next week and there is no class! To my surprise, my class actually responded with "HUH~~~ no class? Why no class?" "At home very boring". Actually I was surprised and amazed by the class response and because of their enthusiam, I decided to make it an outing day! YAYS!!! To the science centre! I was so happy about the response of my kids wanting class on a public holiday as it proves that ISUN kids JUST LOVE LESSONS & they enjoy learning in class :) You can consider this as post Children's Day celebration as well :) A sincere appreciation to the kids and parents who specially shifted some of the lessons for their child to join me in this outing! While waiting for the others...... Selfie time! All arrived on time, before 10am. I can totally feel and excitement and was also super excited about going to the Human Body Exhibition and the other areas of science centre!  Group photo

From the oceans, let's rocket to the sky to understand about the powerful eagle, king predator of the sky. As the video does not mentioned anything much, below is a summary of the adaptations of the eagle. Eagle's Adaptations Eagles and other birds are commonly tested in Primary Science Examinations, especially with regards to their body shape, feet and beaks Primary 6 Science Application Questions: Adaptation QUESTION 1 Two birds, Bird A and Bird B, were kept separately in two cages as shown below. 300g of seeds and 50 ml of nectar were placed in each cage at the start of the experiment. After two days, the amount of seeds and nectar were recorded in the table shown below. Mass of seeds at the start of the experiment (g) Mass of seeds at the end of the experiment (g) Cage with Bird A 300 300 Cage with Bird B 300 100            Volume of nectar at the start of the experiment(ml) Volume of the nectar at the end of the experiment(ml) Cage with

From the land, let's move on to the pitch dark sea. In the dark, many water creatures seek out for the light. However, unbeknown to them, they are courting their own death. Let's take a closer look at this deep sea angler fish. You may find it familiar as you may have seen from the movie, Finding Nemo. Anglerfish Adaptations: Light-emitting structure - Structural adaptation to attract prey so as to catch it Waving light-emitting structure - Behavioural adaptation to attract prey so as to catch it Many sharp jagged-teeth that are angled inwards - Structural adaptation to catch hold of prey easily and preventing them from escaping   ¹   Extended jawline - Structural adaptation to swallow prey easily Expandable Stomach - Structural adaptation to feed on prey bigger than itself and stock up food in the food-scare dark waters  ¹ Special sense organ  - Structural adaptation to look for mate and reproduce Male anglerfish attach himself to female anglerfish: Behavi

The world's is full of surprising living creatures that have their own strategies to survive and adapt in the wild. By having various adaptations, be it structural or behavioural, the animals have enabled the survival and continuity of its own species. For the very first post of this series, we have the Regal Horned Lizard.  As you watch the video, take note of its adaptations and identify if it is structural or behavioural. Adaptations of Regal Horned Lizard Sticky tongue - Structural adaptation to catch its prey Immune to ants' venom - Structural adaptation to protect itself against prey Body of hard scales - Structural adaptation to protect itself against  prey Thin blood capillaries underneath  the lizard eyes that can rupture easily at will - Structural adaptation to escape from predator Squirt blood at predator: Behavioural adaptation to escape from predator Blood with anti-canine repellent property - Structural adaptation to escape from preda

Isn't it great to be able learn Science in such a Simple and Fun way?  Science is really just that EASY! Join us today for our June workshop!

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.

Respiration and Photosynthesis With air quality going downhill, there may be chances that we need to carry plants around as our oxygen tank.  The working mechanism is based on 2 simple concepts of Primary 5 Science, Respiration and Photosynthesis.  As seen from the picture, the man is wearing a mask connected to the plant. As the man respires, it gives out carbon dioxide.  The carbon dioxide, together with water and light, the green plant with cholorphyll photosynthesises and produces oxygen for the man to respire and survive.   A summary of the both respiration and photosynthesis processes are below: Respiration Respiration is the breaking down of digested food with oxygen to produce energy. The equation of Respiration Sugar (from digested food) +  Oxygen (from inhaled air)   è  ENERGY (for body to use) +  Carbon Dioxide (to exhaled air) + Water Vapour (to exhaled air)  *NOTE* All living things respire including plants. Respiration takes place ALL the
