Analyze and Conclude
1) Observing What force is responsible for the difference between the weight of each object in the air and its apparent weight in water ?
Buoyant force is responsible for the difference between the weight of water and air  

2) Analyzing Data How is the buoyant force related to the weight of water displaced ?
The water displace have weight of 0.0098N 

3) Forming Operational Definitions Define buoyant force and describe 2 ways you can measure it or calculate
Buoyant force is a force that gives an ability to float in a fluid. We can measure the object by measure the place in water and measure in the air then subtract to have buoyant force

4) Drawing Conclusions Explain what causes an object to sink or to float, using the terms buoyancy, weight, force, density, and gravity
Buoyant force is a force that give the object to be float but it will sink because of our earth gravity that pull object down to the core center of the earth

Launch LabHow can you bend water?

1. Infer Why did you rub the balloon on your sweaterPredict what might have happened if you simply touched the balloon to your sweater instead of rubbing it.

We have to rub the balloon on the sweater because it make the balloon to have electric charge and make water change the direction in the opposite way of the balloon. If we just simply touched the balloon on the sweater it will not create electric charge enough to change the water direction

2. Key ConceptWhy do you think the balloon interacted the way it did with your sweater and with the stream of water?

The balloon and sweater is interact by electric charge and it attracted the electric charge of the water so it change direction

Testing electrostatics that is in the balloon

Exploring color

When the red lens and green lens has been shining by the light the color get yellow but when red and blue combine it gets the pink color. The last result is when blue and green combine that will get very dark green.

Another thing that we know is when the original lens pass through the paper the lens will allow only there own color so we see only the color of the lens in the paper other colors will be absorbed or reflect out.

crystallization of milk

1)  why do we add salt to the ice?
That will make the ice lower degree lower temperature so it can freeze the milk quickly

2)   why do we add the cookies and other things, only after the milk has frozen slightly?
It is difficult to put the thing before milk has frozen because it will freeze slowly

3)  what are two factors that affect the freezing you think?
salt that is solute when salt dissolve in water because salt make particle harder to come join close together and sometime this happen in sugar

4)  why do you need a bit of air in the bag?
The air will help easily from ice and freeze it to milk to become ice-cream
