Summary: This week something that I learned was that algal bloom is bad for fish because when there is too much algae oxygen gets taken away. If oxygen is taken away then the fish won't have any oxygen to breath because the fish breath in the oxygen from the water but the algae takes that oxygen which kills the fish. If the algae keeps growing and dies it takes a lot of oxygen from the water and the fish won't have any oxygen left to breath. There are also other things that can kill fish like chemicals such as oil and phostphates. These 2 things aren't good for the water because it may contaminate the oxygen in the water and the phosphates can make too much algae and cause an algal bloom in the water.
SP7: Engaging in argument from evidence
In science, reasoning and argument are essential for clarifying strengths and weaknesses of a line of evidence and for identifying the best explanation for a natural phenomenon. Scientists must defend their explanations, formulate evidence based on a solid foundation of data, examine their understanding in light of the evidence and comments by others, and collaborate with peers in searching for the best explanation for the phenomena being investigated.
Did you participate in a class discussion providing evidence for your answers, and/or used the ACE strategy in your work?
In class we all discussed algal bloom and about who or what might have caused it.
Cause and Effect
Identify the cause and effect relationship and provide evidence for the relationship.
Cause: Phosphates from the cattle ranch got into the water and created too many water plants in the river.
Effect: The fish died because the algae (water plant) took all of the oxygen causing the fish to die.
