CELEBRATION~

OMFGGGGG I JUST FINISHED WRITING THE SRP!!!!!!!!!!!!!!!
:))))))))))))))))))))))))))))))))))








now i just need to finish the booklet T.T

Day 14

The last of my results:
i took pictures of everything again but im only going to add any new results in this post
like these ones:
Acid Water Leaves















Normal Water Leaves













Those white things are drops of water...


we can say that the experiment showed that the normal water plants had very healthy results while the acid water suffered a bit and turned very weak.

Day 13

Finally some more results:
i was looking closely at my flowers and i noticed that the acid water flowers looked more weak and fragile than the normal water plants
take a look for yourself:
Normal water flower

















Acid Water Flower

Day 12

Normal Water

















Acid Water

Day 11

once again were back to not much change T.T
Normal Water
















Acid Water

Day 10

Finally some results that actually SHOW something

Normal Water














Acid Water















As you can see here, the acid water plants have definitely grown different from the normal water plants. the normal water plants look more rigid, strong and healthy where as the acid water plants look more floppy and weak.

Day 9

Normal Water














Acid Water

Day 8

Normal Water














Acid Water

Day 7

Normal Water
















Acid Water

Day 6

Normal Water

Acid Water

Day 5

Normal Water


Acid water

Risk Assesment

yea i know, i should have done this earlier T-T
ok well here it is:

Identify: vinegar, soil
Assess: Vinegar & soil can be splashed into eye. Soil can be ingested
Control: be careful when dealing with soil and vinegar and do not eat soil
dispose: place the soil into a bin after the experiment is over

Day 4

so in four days, not much difference (yet) but when you look closely, you can see that the leaves of the acid water plants have started to turn kind of soft and floppy unlike the tap water leaves

Acid water leaf




















Tap Water Leaf

Day 3

There seems to be a slight colour change ( acid plants are lighter than tap water plants) and the leaves of the acid plants are like shriveling up

Acid Water Plant













Tap Water Plant

Day 2

Not much difference here either... but i have to put up all the info here so here ya go !

Acid Water Plant















Tap Water Plant

Day 1

So here are the pics for Day 1
nothing much has changed since its the first day but yea... here you go :)

Acid Water Plants



















Tap Water Plants

method

first i collected 6 plants (for repetition) and divided them into 2 groups, the acid water group and the tap water group. ( the things that i kept the same between all the plants were the plant type, amount of water, type/amount of soil, pot size, location)
Then, for the next two weeks, i plan to water them at the same time in the morning and at night (8am and 8 pm) with their specified water types.
Each day i will take a picture of the plants to see if there are any changes in them, and record all changes and observation

This is how i set up my experiment

do i need anything else? :S

So far..

Well the first week of my experiment has begun, i went shopping and bought 6 Dianthus plants which are approximately 23cm tall. i planted them in the same sized pots (height 9cm, diameter 12cm) with the same soil (dug up from my other pot plants so i dont know the name of the soil but i guarantee its the same).
I plan to give them 200ml each/ day (100ml in the morning, 100 ml at night). however three of these plants will be recieving acid rain ( a mixture of vinegar and water) whislt the other three get tap water.

More research....

Did anyone else have a problem with logging in on blogger? o.o
uh.. anyway i couldnt find 6 plants of the same type in any stores this week, but one of the stores said that they would pre order some for me ^^ how nice of them. anyway i was doing some research and i found this information...

Effects of acid rain on plant life.

"Both natural vegetation and crops are affected by acid rain. The roots are damaged by acidic rainfall, causing the growth of the plant to be stunted, or even in its death. Nutrients present in the soil, are destroyed by the acidity. Useful micro organisms which release nutrients from decaying organic matter, into the soil are killed off, resulting in less nutrients being available for the plants. The acid rain, falling on the plants damages the waxy layer on the leaves and makes the plant vulnerable to diseases. The cumulative effect means that even if the plant survives it will be very weak and unable to survive climatic conditions like strong winds, heavy rainfall, or a short dry period. Plant germination and reproduction is also inhibited by the effects of acid rain." along with this picture:

i guess this is what my test results will be like

SHOPPING!

ok so im not really sure whats due before our next blog submission so ill just write out my shopping list :)
first i have to buy 6 pot plants (going to repeat the experiment 3 times, so use 2 pot plants per experiment) ... not sure yet what type im going to buy, probably the cheapest one but i might research some plants that are good for experiments
then i have to make my acid rain, using vinegar and water as i said last month. the instructions that i have will work as it gives a ph reading of 4.0 when acid rain has a ph reading of anything less than 5.6
hmm.. what else...
oh rite soil, fertilisers (maybe), the thing that pours out water and cannot remember the name of (i know rite can you believe i dont have one)..is there anything else?

science graph

its been a while since i published my last post but im not quite sure if were supposed to start the experiment yet...
anyway here is my graph

originial ideas

i didnt know that we were supposed to put up all of our ideas so ill guess ill do them now...

The effectiveness of Blu Tack on holding up a poster in hot dry conditions.

What conditions keep a balloon maximally inflated for the longest period of time

How good are people at hearing one voice in the crowd?
The ability to judge distances.

The human ability to balance. Stain removal properties of various pre-wash
products e.g. preen, napisan ect on a stain like shoe polish.

Cooking position in oven for muffins. Test an amount of batches of muffins and cooking times, position in oven to achieve the most efficient and best results, top shelf, middle shelf, bottom shelf. (hypothesis: heat rises the top shelf there fore the top shelf muffins will burn first)

i probably should have written these down as my first post .... my bad XD

Variables

the independent variable of the experiment will be the kind of water given to the plant (either normal water or vinegar water)
the dependent variable of the experiment will be the effect on the plant.
the controlled variables will include the amount of water each plant gets, each plant is the same type, the amount of sun each plant gets and the type of soil/fertiliser the plant gets.

how to make acid rain

http://www.newhavenscience.org/4STCEcoLesson10.pdf <----- says that20 ml (4 tsp) of vinegar + 2 liters (2 qt) of water = imitation of acid rain with a pH of 4.0 as acid rain has a pH of anything less than 5.6

Information

http://www.epa.gov/acidrain/effects/forests.html#a3 <--- This site says that the effect of acid rain on plants is that acid rain is likely to weaken trees by damaging their leaves, limiting the nutrients available to them, or exposing them to toxic substances rather than killing them instantly.

http://www2b.abc.net.au/science/k2/stn/archives/archive85/newposts/1364/topic1364890.shtm<--- this says to give plants around 1 litre of water/week to every litre of soil.

editing my experiment

maybe i should just stick to acid rain and normal rain...so in this experiment, i will use just vinegar water (acid rain) and normal tap water.

NEW SRP

instead of figuring out water content, i plan to experiment to see if plants are affected by the type of water that is given to them. In this experiment, i will use vinegar water, tap water and sugar+salt water. The types of water can represent acid rain, normal rain and rain washing down nutrients to plants.

science experiment

decided what to do for my science report, im going to experiment to see if high water-absorbing vegetables, will change colour according to the colour of the water given to them.

Hello world :)
