Summary: This week I learned that sediment can make rivers dirty and fish in the rivers might not be able to see through all of the dirt. Fish also need food and oxygen but fish also need an environment that they could be able to live in. For instance some fish may need the water to be a certain temperature or have a certain amount of light. There are also things that can make rivers dirty such as sediment and block out light for certain fish who can't live in dark places. Since some fish can't see in the dark they won't be able to find food to eat. Sediment can also effect the temperature of the river because if sediment only blocks out a certain place of the river everywhere else would be covered in sun and would get hotter making some fish die.
SP4: Analyzing and interpreting data
Scientific investigations produce data that must be analyzed in order to derive meaning. Because data usually do not speak for themselves, scientists use a range of tools—including tables, graphs, drawings, and statistical analysis—to identify the significant features and patterns in the data.
Did you create a graph, table, drawing, etc. of the data you obtained in an experiment?
We did an experiment in class tells us which lakes, ponds, and rivers were polluted and put that data on sheets of paper.
Cause and effect
WHEN WE "DO" SCIENCE WE TRY TO FIND OUT THE REASONS WHY THINGS HAPPEN.
Tell us the story of a cause and effect relationship you observe. This can be something that you notice in class or outside of class.
Identify the cause and effect relationship and provide evidence for the relationship.
Cause: The sheep trampled on the plants near the river and the plants were keeping the sediment from going in the river. But since the plants were trampled the sediment went into the river.
Effect: The effect is that the sediment is blocking the sun and is making it hotter in certain places. Some fish also can't see in the dark part of the lakes or river and since it's dark the fish can't find their food.
