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.

                             Global warming 

Global Warming Causes

Global warming is primarily a problem of too much carbon dioxide (CO2) in the atmosphere—which acts as a blanket, trapping heat and warming the planet. As we burn fossil fuels like coal, oil and natural gas for energy or cut down and burn forests to create pastures and plantations, carbon accumulates and overloads our atmosphere. Certain waste management and agricultural practices aggravate the problem by releasing other potent global warming gases, such as methane and nitrous oxide. See the pie chart for a breakdown of heat-trapping global warming emissions by economic sector.


Global Warming Emissions by Economic Sector



Global warming is projected to have a number of effects on the oceans. Ongoing effects include rising sea levels due to thermal expansion and melting of glaciers and ice sheets, and warming of the ocean surface, leading to increased temperature stratification.



Global warming 'cure' found by scientists. A "technical fix" that could stop global warming by taking billions of tons of carbon dioxide out of the atmosphere and save the coral reefs from being destroyed by acidification has been developed by scientists.

The grass is a producer which eat the bird which is a consumer. Energy come from producer by photosynthesis and the consumer take the energy by eating the producer.

Symbiosis

Symbiosis
Symbiosis is the interaction between two different organisms living in close physical association, typically to the advantage of both.



It is separated into 3 main groups.


   Commensal - One side get benefit one side don’t get and not harmful


   Parasitic - one side got benefit one side don’t and get harmful.


   Mutualistic-Both side get benefit.   

Commensalism

Commensalism is an association between two different species where one species enjoys a benefit, and the other is not significantly affected. 

Parasitism

Parasitism is an association between two different species where the symbiont benefits and the host is harmed. 

Mutualism


Bacteria in Large Intestines
Mutualism or interspecies reciprocal altruism is a relationship between individuals of different species where both individuals benefit.

My favorite science topic

My favorite science topic is  Adaptations Because I think I want to know many about Predator , animals  or about weapon.and I like to Adaptations of the topic because I think it funny and I know more about animals I know more of the animal of the camel or polar bear.
