Experiment in Progress...

The three flavour i chose are "Delicious Apples", "Pumpkin, Potato & Beef" and "Peas and Zucchini". :)

the apple one opened and it smells REALLY REALLY nice, i'm not kidding.

the peas and zucchini one doesn't look so nice.. looks like it's mouldy already..

this one doesn't smell so good. :O

the three glasses of baby food are now places in a darker place in front of the window...which is hot in day time and really cold at night, with a lot of wind coming in.

:)

i was about to chuck the lids into the bin but then i saved the apple one and ate the food off the lid, it was nice. i think from now on i have found myself a new dessert.

Method & Aim & stuff..

Aim: To investigate which type (flavour) of baby food grows mould the fastest.

Hypothesis: The baby food with meat (in my case, it's beef) will grow mould first out of the three.

Equipment: Three different flavour of baby food, air

Method:

1. Open the three glass/cans of baby food.

2. Leave the three glass/cans of baby food in exposed air.

3. Wait until mould starts to develop on/in the food.

4. Observe changes.

5. Record observations in a table.

Variables:

Independent variable: time

Dependent variable: which flavour grows mould the fastest

Controlled variable: the different flavours of baby food

yeah, i think that's about it..i'm so looking forward to my baby food to grow mould... :|

what is mould?

"Mould is a type of fungus that grows on plants and fibers and is most often associated with damp, musty locations such as bathrooms, basements and attics. Mold travels through the air as tiny spores which like to make their home in wet areas, where they will breed. If mold is spotted, it's best to nip it in the bud immediately lest it spread to other areas. It's also a good indication of a moisture problem, which should be dealt with as soon as possible."

ultured molds are used in the production of foods, including:

• cheese (Penicillium spp.)
• tempeh (Rhizopus oligosporus)
• oncom (Neurospora sitophila)
• Quorn (Fusarium venenatum)
• bread
• sausages^[3]
• soy sauce

eeek, looking at these pictures of mould kind of make me regret doing this experiment, but i've already got my baby food so i shall start soon. :)

Baby food growing mould.

Um, ok. This time I've got all the variables, I think.

So I want to find out how long it takes for a certain flavour of baby food to grow mould...and I think I'll buy different flavours of the same brand of baby food. So I'm actually comparing between the flavours and see which one grows mould the fastest.

Independent variable: time

Dependent variable: which flavour grows mould the fastest

Controlled variable: the different flavours of baby food

So er.. yes, that's the basic idea.

new idea..

Ok, so now that i know my font isn't really clear i shall change it to black. hopefully Ms Zhang can see it this time. :)

my idea wasn't really that scientific, so i'm going to abandon that idea and find a new one!

So i googled a lot of things and found that there's an experiment called the "rubber egg experiment" or something like that. it sounds really cool.

So the main idea of this experiment is that an egg (or a number of eggs) will be placed into white vinegar, they'll be in there for a few days then the eggs' surfaces are meant to appear or feel like rubber.

The theory behind this is that the shell of the egg is made up of calcium carbonate, and when calcium carbonate is placed in acidic vinegar, the calcium carbonate will be "eaten up" or dissolves. This will leave the inner membrane of the egg behind and give the egg a feel that's rubber-like.

some info on shortsighted-ness

Short sighted-ness

"If your cornea is too curved, or your eyeball too long, light rays from distant objects focus in front of your retina. This makes objects seem fuzzy or blurred.

Nearby objects don't look fuzzy, because the light rays enter your eye at a slight angle. This means they focus on your retina properly....

Myopia usually develops in children or young teenagers. You are more likely to develop myopia if it runs in your family." -from Bupa (bupa.co.uk)

no wonder why i wear glasses, both my parents wear glasses too.

about my variables...

i don't even know if my experiment will be approved...but.

i think my variables are:

independent: the sign/size of letters that i'm going to write on the sign..

dependent: how far people can see without squinting their eyes..

:D
