pls help..


I did my homework. Then, I watched my favourite television programme.
DS2 wrote: I watched my favourite television programme after I DID my homework.

Answer scripts says: I watched my favourite television programme after I HAD DONE my homework.

Is using \"DID\" wrong? Someone kindly enlighten.

Thanks

Hashroop

'Did' is the simple past tense while 'done' is the past participle. 'Has, ''had' or 'have' are usually followed by a past participle.
Past participles are something like 'past past' tense. 'I watched my favourite television programme' is already past, but 'I' had done my homework BEFORE 'I' watched television, so the doing of homework is 'past past'.

Picture shows an glass aquarium with aquatic plants and some animals like fish, waterboatman and water fleas. Tank is sealed with a glass plate and whole aquarium placed in a brightly lit room the whole day.


Qn : Which of the following statements is correct about the organisms after several months?

1) All the organisms will die as there is hardly any air in the tank
2) The plants can survive longer than the larger animals in the tank
3) The animals will all die in less than a day as there is insufficient air
4) The organisms could still survive as there is a continuous supply of air.
Answer is 2)

Son's answer is 4) as there is a constant exchange of gases between the plants and animals - plants give out oxygen (during photosynthesis as the glass aquarium is placed in the light whole day) for the animals to take in and animals breathe out CO2 for the plants to take in. But my question is 'can this exchange of gases take place forever in a sealed container - is there a time limit to this? Note the question says 'after several months'.

My answer is 2). The plants will survive the longest as the conditions of the surroundings have fulfilled the necessary conditions for survival. They have oxygen from the oxygen they made from photosynthesis, food from photosynthesis and water all around them. However, the animals do not have food.

Hi all


Please help with this question:

Thanks in advance!

This is a good example of how irresponsible primary sc dept can be. It is common knowledge that without any restraint to hold back the ball, it will be attracted to the \"toy\" (inverse square law). It will not remain floating in the air as claimed. Therefore, the situation as shown in the question cannot happen... or did I miss something new that is being thought nowadays.

Maybe the force of gravity and the magnetic force of attraction are the same in this toy and so they cancel seach other out and the sphere remains floating in the air, like if you put a sphere in space and not move it.

P5G:

Please help.

Question 18 - Energy
Worksheet answer is (1). Should the correct answer be (2)?


Question 21 - Electricity
Worksheet answer is (1). Should the correct answer be (2)?


TIA.

Q18: I agree with the answer. The sun's heat is concentrated on the paper and so the heat energy goes to the paper. The paper burns, so there is fire. The fire has light energy. So the energy conversion is HEAT ENERGY TO LIGHT ENERGY.

Q21: I agree with the answer. Closing S3 would be no use to making the bell ring. S1 and S2 makes the bell ring.
