Emotions (to be tested in Jan'13)

Fear

I stood rooted to the ground. My legs turned wobbly and I could not move even an inch. A cold chill ran through my body, sending beads of cold perspiration down my spine. With quivering lips, I muttered in an edgy voice, “What could that be?” Fear engulfed me. My heart thumped. I could feel it coming out from my mouth. I could no longer contain my cowardice and broke into tears.

Anger

I clenched my fists tightly, piercing each fingernail into my palms. I bit my lips and took a deep breath. It was of no use. The raging fury in me gushed out through my mouth, “Put that down!” I could no longer contain my temper. Anger engulfed me, taking away all composure I had. Nothing could put out the wild fire in my chest.

Joy

My eyes glittered in bliss. I was riding on cloud nine, making my way to the top of the world. I had never felt better. I was overwhelmed with euphoria. It was so much excitement that I could not contain my joy anymore. The smile on my face extended and I was grinning from ear to ear. I boasted in glee, “What else can I ask for?” Tears of joy welled up in my eyes.

Sorrow

I had not expected it. Sadness had taken over every part of me. It felt like a dagger stabbing right into my heart. Deep grief engulfed me. Tears of sorrow welled up in my eyes. I tried to hold back the beads of helplessness, but to no avail. Nothing else could seep into my dark world, except for, “Why?” There were no answers and only questions echoed in my vacuumed mind.

Embarrassment

I flushed. “Does anyone have a paper bag to spare?” I mumbled in complete embarrassment. How I wished I could hide myself somewhere to save all this humiliation. Even if it were just a paper bag, it would suffice. Beads of cold perspiration gathered at my forehead. I had never felt worse. Little did I expect myself to be caught in such a situation.

Regret/Guilt

All I needed was a second chance to undo the wrong deed. “Look before you leap, child.” My mother’s advice fell on my deaf ears. My heart ached. It felt like I had just stabbed myself with a dagger. I had only myself to blame and no one would bother to nurse the aching heart of a wrongdoer. Tears of guilt and remorse trickled down my sunken cheeks. I truly regretted my foolish act.

P5/6 - Composition Test

I clenched my fists tightly and bit my quivering lips. The anger and frustration in me were strongly suppressed as I convinced myself not to lay a finger on him. “Your sister is a thief!” the proprietor spoke accusingly. I was confident that he must have made a mistake. We were poor, but would never resort to stealing.

“Sir, could you have made a mistake? Please give us a chance to clear up the air,” I pleaded humbly. Throughout the confrontation, my sister hung her head low and kept mum. I knew that I had to do anything and everything I could to protect her.

Shaking his head, the shopkeeper held up his hand to signal for me to wait. He went into his office and then called for me to follow him. Was he trying to trap us in the office while he called for the police? I had no answers, so I had no choice but to obey reluctantly.

He turned on the television set and my eyes were set on the screen. The callous truth struck me – my sister was the female lead in the video! She had eaten the bun without paying! My heart sank and my mind was in a complete blank. “Shame on me for thinking the worst of the proprietor,” I muttered in complete embarrassment.

I looked at my sister. She finally looked at me straight in the eyes. “Sorry,” she mumbled. Tears welled up in her eyes. Hunger and desperation had forced her into theft. “You can work for me and I can provide for your meals in future,” the angelic voice of the proprietor rang in my ears.

Water boils at 100 degrees celsius , melts at 0 degrees celsius and freezes at 0 degrees celsius.
Impurities such as salt or sugar can increase the boiling point of water and lower the freezing and melting points of water. Therefore, sea water boils at a temperature above 100 degrees celsius.
When water boils, air in the water escapes in the form of air bubbles. As such, plants and animals cannot survive in boiled water as there is no air in boiled water.

P6 Science Revision-Man and His Environment

Q1. When does deforestation occur n what is a recommended remedy to this problem? (3m)
Ans: Deforestation occurs when forests are cleared and trees are cut down to clear land for the construction of buildings and to retrieve raw materials for construction, furniture making and paper production. 
A recommended remedy is reforestation.

Q2. Explain a positive n a negative impact of science and technology on our lives. (4m)
Ans: Science and technology has helped to produce fermented food and canned food. As such, a greater variety of food is produced and these foods have a longer shelf life. Thus, the positive impact is that food is more readily available.
Science and technology has also introduced more forms of vehicles which inevitably produce harmful substances that pollute the air. Hence, the negative impact is air pollution. 

Q3. How is Genetic Modification (GM) useful?
List 3 different ways. (3m)

Ans: GM enables farmers to produce crops that are pest-resistant or drought-resistant, thus leading to a greater yield for the farmers. 
With pest-resistant crops, less pesticides is needed and this results in cost savings for the farmers and less pollution to the environment.
The quality of food is improved by changing flavour and having higher vitamin content.
