Aim:
To find out if the colours of light affects the germination of plants.
Hypothesis:
No, because light colours do not change the germination because light gives the same energy.
Materials needed:
1. 3 pots of plants
2. 3 different colours of light
Procedure:
1. Put the pot in a dark place with seed
2. Use different colour light.
3. Water them every day.
4. Wait for a few days for the germination.
Materials needed were too less you did not say about the water and you wrote in your procedure *Water them every day* If your materials does not have water, where do u get it from?
ReplyDeleteyes i think so too.
Deletehe should water them as he must be fair
#1 the student was trying to explain the hypothesis instead of just writing the prediction.
ReplyDelete#2 put the pot in a dark place with seed. It did not say abything about a seed.
#3 the procedure is not explained clearly.
#4 the aim is to find out if different colours of light affect germination. Why is there no seed int the materials and instead says 3 pots of plants.
1.He does not need a seed when he need three pots of plant.
ReplyDelete2.Use different light everyday or it is always the same light? Not enough infomation
4. What is the duration?
But he said the germination of the plant , shouldn't he start with a seed ?
DeleteBut for the materials, he said that three pots of plants.
Deletethe materials are wrong because it is asking for germination.
DeleteI agree, Ivan
DeleteThe hypothesis should be:
ReplyDelete#1 No, different colours of light will not affect germination.
Or
#2 Yes, different colours of light affect germination.
There should be three set-ups. As you are using seeds, there should be : water , air and warmth. You did not mention that you have to put the seeds in a plastic container with cotton wool . Place all three set-ups in a dark cupboard . Above each set-up , stick a different coloured light bulb or torch to the cupboard. Water the seeds daily . Take down the rate of how fast a set-up's seeds are growing each day . Then you will know if the type of light affects the growth of the seed .

Agree :)
Deletemisha
I agree too. :)
DeleteI also agree.
Deleteno duration. procedure and materials needed are unclear.
ReplyDeleteThere is too little materials for materials needed
ReplyDeletethe aim is correct.The hypothesis i wrong because it is supposed to be prediction not an explanation.the materials needed are correct.the procedure is wrong because you do not need to put the seeds in a dark place it does not have leaves steps number 2 and 3 and 4 are correct.
ReplyDeleteYou should have three set-ups. A,B,C. put the seeds on a wet cotton wool in a container labeled A,B or C in a black box and poke a coloured flashlight through a cut-out hole in the lid. water the plants daily for one week. record your observations in a chart. if the plants are the same, that means different colours of light does not affect the germination of plants. if the plants become different, that means different colours of light does affect the germination of plants.
ReplyDelete~Misha (: 32 :)~
oh yes, the Hypothesis is wrong!
Deletemisha
And you used " Oh yes " too =.=
DeleteWei Ting whats wrong with *Oh yes*???
DeleteIf you say like this then you cant put the face too.
the materials are:
Delete-cotton wool
-green bean seeds
-3 different colouerd flashlights
-water
-3 black boxes
-chart
~misha~
you cannot put Anonymous, Misha
Deleteare black boxes really needed? its testing for light, misha.
DeleteOh yes , the hyphothesis is wrong as he explained. If he already knew the explaination , why do an experiment ?!
ReplyDeleteWei Ting has a point.
ReplyDeleteTesting germination needs seeds, not plants. If you are using plants, you cannot test anything because plants = germinated seeds. Hypothesis should be prediction but you wrote the explaination too. It is not needed. Try not to put things that are connected away from each other like *Put the pot in a dark place with seed*. It should just be *Put the pot which has a seed in it in a dark place*. Use a different colour light for what? You did not say anything about WHAT you need to do with the lights. *Wait for a few days for the germination*, Few days equals how many days? Speaking the precise time would be more..... correct.
ReplyDeleteagreed.
DeleteOne of the best replies I've read :)
Delete- Wei Ting
Thank you Wei Ting ^__^
DeleteThe materials needed are not correct because the aim is for germination so it needs 3 seeds not 3 pots of plants.4 are correct.
ReplyDeleteMisha so are you saying this piece of work is yours?(good point Wei Ting)
ReplyDeleteI'm very sure it is :\ We have the same mind !
Delete- Wei Ting
stanley, i put my name there jusi to own my comment. i am not saying the work is mine.
Deletemisha
Ah o__O ok i didn't understand
DeleteIts was because you said *oh yes, the hypothesis is wrong* so i thought that you admitted you were wrong.
I agree with you wei ting!
ReplyDeleteyelong
1.The hypothesis is correct because the plant has no leaves so even if light colours are the same the germination.
ReplyDeletejonathan quek (29)
The aim is correct but the hypothesis is wrog you should write your prediction and not the explanation .In your procedure you missed out many steps which includes time, duration and what few days?! BE SPECIFIC!okay? If you are using plants, you cannot test anything because plants = germinated seeds.
ReplyDeleteStudent D's hypothesis is wrong because you are suppose to only type your prediction not your prediction and why and his reason is also wrong.Student D should also say 3 potted plants instead of 3 pots of plants.For the materials needed,Student D should add tripod stand,forceps,boiling tube,5 beakers,wire gauze,gas burner dropper,white tile alcohol,water and iodine solution for the starch test and the experiment.Procedure should also be clearer,there should not be any seeds in the pot and it should be a plant.Student D also missed out some steps after that step. The steps should be to take out the plants from the dark place and put it under the lights.It should be different colour lights on each plant.Step 2 and 3 should be oppopsite.Step 4 is also wrong as student D did not write the duration and you should wait for 2 to 3 days and do the starch test.For the starch test, you should pluck the leaves from each plant and put them in the beaker.After that but the beaker on the tripot stand and put the wire gauzeon the tripod stand.Then,put the gas burner below the tripod stand.Leave it for about 30 seconds. Take it out and put it in warm alcohol until it loses its colour.Put it in warm water tosoften it.Put the three leaves on the white tile.After that,put the iodine solution in the dropper and drop it on all the leaves.See whether all of them turns dark blue.
