Primrose Cloud

Cloud
Cumulus 
Cumulus cloud look like as puffy, cotton and fluffy, and have flat bases.
              Cumulus cloud being low-level cloud are generally less than 2000m (3300ft.) in altitude unless
they are more vertical cumulus congestus form
Stratus
Stratus cloud look like huge Gray blanket 
              Stratus cloud mean rain if it is warm or snow if it cold. Sometimes stratus cloud are on ground or very near the ground, We called fog.

Cirrus
Cirrus cloud look like frezzing of super cooled water droplet.
                Cirrus cloud are thin and wispy, and common in high level cloud, This cloud found in higher than 20,000 feet (3000 meter).

Observation: 20 height go slow
                     40 height go faster than 20 height
                     60 height go faster than 20 and 40
                     80 height go fastest

1.Describe how the ball rolls off the ramp at each height- discuss the effect of bouncing or other factor.
Ans- 20 height the ball go straight line
        40 height the ball go same with 20
        60 height the ball go awry 
        80 height the ball go bounce
2.Discuss what is the fastest speed reached and any factors that could improve this.
Ans- Yes
3.Does the ball travel in the straight line, why or why not.
Ans- Yes because the ball will find the optimal  angle to maximize acceleration, so it travels the farthest and/or the fastest.

Pollution


     Visual pollution occurs when an individual cannot enjoy the view in a particular area due to the negative changes in a natural environment. This can include billboards, trash cans and dumping areas that are exposed, telephone towers that are erected in neighborhoods, electric wires, ugly buildings and even broken-down vehicles. This type of pollution can be controlled through the implementation of laws. For example, the Federal Highway Beautification Act of 1965 limits the number of billboards that can be placed on highways and roads.
What are some causes of visual pollution?
son
             
        Pollution must be taken seriously, as it has a negative effect on natural elements that are an absolute need for life to exist on earth, such as water and air. Indeed, without it, or if they were present on different quantities, animals – including humans – and plants could not survive. We can identify several types of pollution on Earth: air pollution,water pollution and soil pollution.
        We must use the bicycle instead the car. Because there will have a air pollution
We can't throw the trash on the road and in the water. Because it will have a water pollution. And the fish in the water will died because there have poison.

          Symbiosis 

  1. Parasitism is a non-mutual symbiotic relationship between species, where one species, the parasite, benefits at the expense of the other, the host is harmed
  2. Mutualism is a symbiosis that is beneficial to both organisms involve
  3. Commensalism is a relationship between two organisms where one receives a benefit or benefits from the other and the other is not affected by it.

My favorite experiment in add science is The fish experiment because It's my dream to have a pet but my house is too small to have it.

Primrose Predator Prey


1. The komodo dragon adaptation with a rock
2. The komodo dragon lick buffalo so the poison got in to the buffalo
