                                                        effect of gravity on speed

Introduction
Gravity provides a constant acceleration (force) on an object.  The effect is changed by using ramps at different angles. In this lab, you will find the optimal angle to maximize acceleration on a ball bearing so it travels the farthest and/or the fastest.  Friction is the opposing force created by the surface interactions.  Whenever something rolls due to a force, friction will oppose this force and slow it down.

analysis
  1.Describe how the ball rolls off the ramp at each height—discuss the effect of bouncing or other factors.
  from result of lab i think ball in bouncing high when it fall from higher

2.Discuss what is the fastest speed reached and any factors that could improve this.
i think if it have medeim high ramp it will be go fastest because gravity it make sense of high

3. Does the ball travel in a straight line, why or why not?
  no some time ball is not go in straight line because the floor is not smooth

                                                                            acid rain
Image result for causes of acid rain
  
Acid rain is a rain or any other form of precipitation that is unusually acid, meaning that it possesses elevated levels of hydrogen ions (low ph). It can have harmful effects on plants, aquatic animals and infrastructure. Acid rain is caused by emissions of surfer dioxide and nitrogen oxide, which react with the water  in atmosphere to produce acids.Nitrogen oxides can also be produced naturally by lightning strikes, and sulphur dioxide is produced by volcanic eruptions. The chemicals in acid rain can cause paint to peel, corrosion of steel structures such as bridges, and weathering of stone buildings and statues.

Our Pyramid Food Chain

Our Pyramid Food Chain

Our pyramid food chain have grass, bird and human (us). Grass is a producer. Bird is a primary consumer and human is a top of this food chain (Heterotroph / secondary consumer). We all know that primary consumers are herbivores such as birds, fishes, etc.

As these picture are shown down below, there is a producer (autotroph), a herbivore (primary consumer), and a carnivore / omnivore (secondary consumer / heterotroph). 

There are pictures that you can examine and determine below.

                    what is my symbiosis about


my symbiosis poster is about the living together of two dissimilar living 

There are 3 types of symbiosis as shown; 
1. Parasitism
It is  a relationship between two organism where one is usually harm and the other get benefits from the relationship.

2. Mutualism

Symbiosis that is benefits to   
both organism involved

3. Commercialism
Is an association between
two organisms in which one benefits
and the other derives neither benefit nor harm.

my favorite topic is biome
this is my favorite topic is biome because human have to live in many biome some live in 
comfortable biome like rain forest. some one live in hard biome like biome desert under sunlight 
is very hot in night is very cool but everyone have to know how to survival in your biome
