Dendrophylax lindenii, the ghost orchid

The bulk of the plant consists only of flat, cord-like, green roots with distinctive "track marks". These white track marks are called pneumatodes and function in much the same manner as stomata allowing the photosynthetic roots to perform gas exchange to support photosynthesis. These roots are used for moisture absorption and their chloroplasts for photosynthesis.

[23/3] Summary of Interactions Chapter 3: Living Together

Chapter 3: Important Learning Points

• An organism is a living thing.
• A population is a group of organisms of the same kind that live together and reproduce in a particular place.
• Population size is the number of organisms in a population.
• Population size increases when organisms reproduce or when organisms  of the same kind move into a place with an abundance of food and water.
• Population size decreases when organisms die or move out of a place in search of food and water.
• A habitat is the place where an organism lives.
• Habitats provide organisms with food, water, air, space and shelter for protection.
• All the population living in a habitat depend on one another for survival. They are interdependent.
• A community is formed when all the different populations of organisms living in a habitat comes together.
• Different habitats support different communities.

Important reminders in your Science Revision

1. Gravitational Force vs Gravitational Potential Energy (MCQ 2014 paper: Q21)

• The amount of gravitational force acting on the javelin is the same at C, D and E. This force is constant as long as you're on earth.
• However, the gravitational potential energy will change. 
• At C, it has greater gravitational potential energy & therefore lesser kinetic energy. 
• At E, it will then have lesser gravitational potential energy as it is converted to greater kinetic energy. 
• This is similar to the Roller Coaster Example, pg 24 in your Energy activity book.

2. Cause, Effect & Purpose (MCQ 2014 paper: Q20)

• In Surface D...
• Cause: Frictional Force between the wheels of the toy car & the surface of the ramp is the least.
• Effect: The toy car is observed to roll down the ramp the fastest. / The toy car took the shortest time to roll down the ramp.
• Purpose: (Applying the experiment in the context of the bathroom floor tiles) It is the least suitable for making the surface of bathroom floor tiles.
• This is similar to the pg 7, Question 2 in your Interaction activity book.
• Whenever question asks to "Explain why", you will need to have the Cause & Effect in your answer. 
• Purpose will be needed when there is an application in another context.

[24/2] NSB, Revision & Practice Paper

- you may use the various types of power stations (application of energy conversion) we have discussed so far.

This task is due tomorrow, 19 Feb. Hand in to Science Monitors.

[17/2] NSB Homework & Some Misconceptions

Energy Activity 2 Experiment - Learning Points

• As the height of the ramp increases, the distance traveled by the car increases.
• As the height of the ramp increases, the amount of gravitational potential energy increases.
• As the toy car moves down the ramp, gravitational potential energy is converted to kinetic energy.
• The greater the amount of gravitational potential energy of the toy car at the top of the ramp, the greater the amount of kinetic energy that is converted into, causing the toy car to move down the ramp faster.

NSB - Difference between Photosynthesis & Respiration

Misconception 1: We use our nose for respiration while plants use their stomata

• Respiration for both plants and animals takes place in all cells.

Misconception 2: Respiration only takes place at night.

• Respiration takes place all the time, throughout the day and night.

Misconception 3: Photosynthesis only takes place in the day.

• Photosynthesis only takes place in the presence of light. If there is no sunlight in the day, photosynthesis will not take place.

Summary table of difference

Homework: NSB - Conversion of Energy from one form to another

We have discussed the following examples on how energy is converted from one form to another.

• During photosynthesis
• During respiration
• When a ball falls from a height

Your task is to read up and write down as many examples on how energy is converted from one form to another. 

- you may use the various types of power stations (application of energy conversion) we have discussed so far.

This task is due Friday, 19 Feb.


Reminder - Things to bring tomorrow.

• Bring along your 2015 Practice Paper (MCQ). We will continue to go through the answers tomorrow.
