My favorite activities in additional science tropic is fish and shrimp lab because we can test  how the small animal live in the bottle and training like a real scientists by doing hypothesis, observation, etc...
My least favorite activities  in additional science tropic is biomes because it hard to remember the long word and hard to spell.

my observation
fish and shrimp lab experiment

1.  What do you think kills the fish/shrimp--oxygen or temperature of water,  why?

I think the fish don,t have enough oxygen because the water is gray and the plant or seaweed is very black and the fish didn't eat it.

2.  Did you find anything interesting in the lab?

The fish is died already but the shrimp is still alive. I think it about the position of the fish and shrimp bottle so shrimp can be alive.

3.  what other things could kill the fish?

The other thing that could kill fish is the temperate is higher in the bottle and fish can not live in it.

fish lab Question

I think the fish is died because the first time that go inside the bottle they move slow and i think they have no oxcigen enough

They use the same bottle but the sun make seaweed oxcigen and fish is eat seaweed so it can alive

I will change the water everyday and put the bottle closer to the sunlight.


 experiment 

1. my experiment 
            1.1 we put the water in the bottle and put seaweed in side 
            1.2 next we put the fish and the shrimp in different bottle
            1.3 we observation the live of fish and shrimp in bottle

2. The jars changed color because some jar have many carbon dioxide so when we put bromothymol will turn         yellow. 

3.The animal will eat plant and then will poo it will be the fertilizer to the plant

4.The fish and shrimp will died because of no oxcigen from the plant 

5.sunlight causes the plants to give off oxygen and no food and oxcigen of animal
