My favorite activity in add science class is terranium lab because it is a challenging and interesting lab. I watched the fish everyday to see what would happen to the fish.  I also like the word Kru Gary say "no pressure". I like this class and enjoy studying in this class a lot.  -- NO PRESSURE -- So far so good.

 What do you think kills the fish/shrimp--oxygen or temperature of water,  why?ans:  I think oxygen is decreasing and too much carbon dioxide which cause the fish died.

Did you find anything interesting in the lab?
ans: The interesting in lab was smell because the smell was very bad in the lab. The died fish made bad smell.

 What other things could kill the fish?
ans: I think the other thing that could kill the fish is the temperature and sunlight.If the fish get too much sunlight so the temperature will get higher and the fish could not adap so the fish died.

Fish and shrimp lab m102 Sino

1) In the lab, we put fish and shrimp into the different bottle with water.  Then put blue food coloring into those bottles. The water change to light blue color after we put blue food coloring.  My observation is that after 3 days the fish died , the water is still blue and the plant is not died.  The shrimp is died too.  This is because oxygen is less and carbon dioxide is increased.

2) The water in some bottles may change color because the water have less oxygen and have too much carbon dioxide,the water will change to yellow.

3) The plant release oxygen in water , the fish get oxygen from plant and eat plant as food.

4) My prediction after 1 week is that the fish and the shrimp will die.

5) In my opinion,the fish will die because the water have less oxygen and too much carbon dioxide because the plant get little sunlight so the plant  produce little oxygen which make the fish die because of so little oxygen.

6)I think my fish is died because the fish is not move and it is sinking to the bottom of bottle.

7)The different between the water in the bottle that the fish is not die and water in the bottle that the fish is not die is the water in the bottle that have died fish is more yellow than the water in bottle that the fish is not died.

8) If i have to do it again ,I will change the plant because I think the bigger plant can produce more oxygen.
