In this assignment I made a presantation  in history. It is called Islam Project. We had to first do a paper with information we had to fill out and then use that paper to work on the project. We had to do 4 slides for each topics.

I learned about all about islam.

In science we had to do a lab report, it was called ” SUGAH SUGAH’. We got to work in groups, my group had to find out what the effect of stirring speed on the rate which the sugar will dissolve in water. Our hypothesis was If we stirr it faster than it will dissolve faster because it is increasing the surface area. The greater the surface area the faster it will dissolve. We did the lab and followed these steps 

1.Gather all materials.

2.Put 200ml of water in each beaker.

3.Put sugar on the filter paper and measure 9g each.

4.put 9gs in each beaker.

5.Get timer.

6.set timer.

7.Stirr each beaker different speeds Ais normal B is fast. 

After the lab was done we had to make a conclusion and mine was –

My question was “What is the effect of the stirring speed on the rate which sugar will dissolve in water?”.My hypothesis was “If we stirr it faster than it will dissolve faster because it is increasing the surface area. The greater the surface area the faster it will dissolve.” My hypothesis was correct because it dissolved quicker when it was stirred faser. In beaker A was stirred slow and the time it dissolved was 1.17 minutes. In beaker B it was stirred fast and the time it dissolved was 30 seconds..
