Make ice-cream in Plastic bag -PunPun M.2/202


1)  why do we add salt to the ice?

 - Salt mixed with ice in this case also causes the ice to melt. When salt comes into contact with ice, the freezing point of the ice is lowered. Water will normally freeze at 32 degrees F. A 10% salt solution freezes at 20 degrees F, and a 20% solution freezes at 2 degrees F. By lowering the temperature at which ice is frozen, we are able to create an environment in which the milk mixture can freeze at a temperature below 32 degrees F into ice cream.


2)   why do we add the cookies and other things, only after the milk has frozen slightly

- To make it easily mixed together.


3)  what are two factors that affect the freezing you think?

 - ice and salt.

4)  why do you need a bit of air in the bag?

- We need air to have the space to make the milk touch the ice.

The Stony Lab question


7.Calculate the density of each of your mineral samples. How could you use the densities to identify the minerals?Ans.Density can be measured with the structure of the minerals. Different minerals will have different density.


8.Would density or color be more useful in identifying a particular mineral? Explain your answer.
Ans.   color because we can identify the mineral by our eye, I think It's the easiest way to identify the mineral.

The impact of society on environment. -PunPun M.2/202


The impact of society on the environment. 

Image result for acid rain
 Acid rain has many ecological effects to the environment. Acid rain makes the water on earth change to Acidic and when the water change to Acidic the fish that have a habitat in that area will die.Acid rain absorbs the aluminium that makes its way from soil into lakes and streams.Acid rain also damages the building and make the tree die.

Image result for nuclear effects on the environment
Nuclear energy has one of the lowest impacts on the environment of any energy source because it does not emit air pollution, isolates its waste from the environment and requires a relatively small amount of land. Nuclear energy stations do not produce air pollutants or greenhouse gases when they generate electricity.

Image result for oil impact on environment
Oil is used to make the petroleum products we use to fuel air planes, cars, and trucks; to heat homes; and to make products such as medicines and plastics. Although petroleum products make life easier, finding, producing, and moving crude oil may have negative effects on the environment. Technological advances in exploration, production, and transportation of oil and enforcement of safety and environmental laws and regulations help to avoid and reduce these effects.

Clouds
 Cumulus clouds are white and fluffy clouds that usually mean the Good weather.

 Cirrus clouds are thin, feather-like the cloud made of ice crystals high in the atmosphere.It's usually mean a change in the weather is coming.


Stratus clouds are the sheet of low, gray clouds that bring light snow or rain.

Food Chain

 food chain show that what is eaten by what.  Each arrow means "eaten by"   
 Food chains begin with plant-life, and end with animal-life. Some animals eat plants, some animals eat other animals. A simple food chain could start with grass, which is eaten by rabbits.

Symbiosis is close and often long-term interaction between two different biological species. Symbiosis has three types. They are Commensalism,Parasitism and Mutualism.

Commensalism describes between two living things where one benefits and the others is not significantly harmed or helped.
Ex. shark and echeneidae, clownfish and sea anemone

Parasitism is about one benefits while the other is harmed.
Ex. parasite and human, louse and human
Multiples is a relationship between individuals of different species where both individuals benefit.
Ex. bee & flowers, crocodile and plover bird
