EVERYTHING

okayy well i havent been on this thing in a long time and yeahh better post up all my things now .
i reversed the purpose of my experiement to whether the viscosity of the liquid affects the bouyancy of the object. i changed it to this because the original experiment just had too many variables to achieve an outcome from it . In this expermiemnt the only thing that is not controlled is the type of liquid .
Soo ive been keeping track of things on word and now i shall blog about it .
My primary purpose was to use a measuring cyclinder but i spent the whole of last week looking for one. so my susstitute is a baby's bottle. i need sometihng that is narrow and this seems to be the closest thing to it. The measurements on the side too are pretty accurate. So i did my experiment this weekend and took photos of it and everything. there arent many as mine doesnt involve many items and yeahhh
soo these are the picture that i took

METHOD

1 . How does the shape of an object affect its ability to float .
Equipment : large bowl with water , a small ball and large ball with the same weight , two balls with different weights , a small slate and large slate with the same weight , two pieces of slate with the same weight .
Method
1. Obtain all the equipment .
2. Pour water into the bowl .
3. Place each of the objects one by one .
4. Determine whether the object floats or not .
5. Record the observation .

2. what type of washing detergent is best at removing stains .
Equipment : 500mL of water , 4 containers on the same size and quantity , 4 pieces of cloth of the same size and absorbance , 4 different types of detergents - Omo , Vanish , radiant , dynamo , dirt .
Method
1. Obtain all the equipment required .
2. Put the same amount of dirt on each piece of cloth .
3. Pour 500ml of water into each of the containers .
4. Add a teaspoon of washing detergent into the water .
5. Place the cloth into the containers .
6. Leave the cloth in for a day .
7. Record the amount of dirt still on the cloth .
8. Repeat steps 2-6 several times .

NEW PLAN ...

So i have to change my idea for my SRP and I'm so sorry ms Zhang that i haven't posted this earlier to inform you.

I'm still undecided on what topics to do though and these are the few ideas that I'm still tossing between.

1. How does the shape of an object affect its ability to float .

Various objects sink or float in water. Whether an objects sinks or floats in a liquid depends mainly on two factors: density and buoyancy.

Density is the measure of the relative "heaviness" of objects with a constant volume.

Buoyancy is an upward acting force, caused by fluid pressure, that keeps things afloat.

So how do these factors relate .

The more denser an object the less buoyancy.

---

(DrStrong) They are related through Archimedes' principle,

F_B = ρgV

where F_B is the buoyancy force, ρ is the density of the liquid, g is gravity, V is the volume of water displaced by the object (in other words, the volume of the object that lies underneath the water surface).

If F_B is greater than the weight of the object, the object will float upwards. If not, the object will sink downwards.

So, the denser the liquid, the GREATER the buoyancy. However, the greater the object weight, the less the buoyancy. Another way to look at it is that the object itself has a volume and density, the product of which is the weight. So if a totally submerged object has less density than the liquid, it will be buoyant. If it has greater density than the liquid, it will sink.



In my experiment i will carry out a simple test to see what affects a object to float or sink.

Objects with the same mass will be put in water. Each object will have a different shape ; large flat piece of slate, small piece of slate, large ball, small ball , etc.

This will determine whether or not the surface area affects the objects buoyancy .

Objects with different masses but same surface area properties will then be tested to determine if the density of an object will affect its buoyancy.



2. what type of washing detergent is best at removing stains

Lauddry detergent typically consists of ionic and anionic surfactant which act as the detergent to remove the dirt from the clothes, perfume, phosphors aticaking agents to prevent the powder becoming one large lump in the prescence of moisture. Biological laundry detergents contain enzymes which act as catysts to "eat" the dirt off of the laundry. Detergents may have other additives such as bleaches and fabric softeners.

In my experiment, i will determine which brand of detergent works best on removing stains. Cloths with dirt and other satins with remains soaked in a container with detergent and water. The cloth with the less dirt is determined as the best detergent.

The variables that are to be controlled are : the amount detergent, the type of cloth and the amount of dirt on the cloths .

CLIMATE GRAPH

Okay this is soo last minute posting but i totally forget about blogging so here goes a massive span blog .

CLIMATE GRAPH

Okay making this was kinda fun

full playing around with paint and editing it in together .

CHANGEE

okayy im not completely sure that i want to do my bone one anymore 

i really want to do something relating to physiological change but i have no idea what though 

and i know it requires a lot of testing 

30 people that is quite a lot soo for now its all about the bones 

soo until then that is all .

...

okay so i finally decided that i should get started on this thing seeing that its due this week 

oh  one thing i learned today was to finally follow people... but half way through i got bored of joining like 150 people and i gave up . and woahh some people are like woahh honestly they have like awesome layoutss and everythingg..i barely know how to navigate this thing.

okay so i was thinking of doing my experiment on the decomposition of bones and i talked to ms zhang about this and she itll be fine. so i would need to keep the variables the same 

if i were to use say salt and vinegar, i would need to set up a series of beakers with bones each in a different quantity of substance 

then i guess i would compare the affect it had the bone marrow ?

but yeahh i want to somehow link this to actual remains found on earth and how each different substance would affect it over many years.. but yeah im still working on that part.
