Summary: This week we learned about classification. Classification is when you put something in a specific category. An example is when you put dogs and cats as mammals and when you but salmon and trout as fish. I also learned about different types of classifications such as eukaryotes. Eukaryotes is an organism that has cells that has a cell nucleus. An organism has to have certain traits about itself to be in a specific classification. Like tetrapods which is an organism that has 4 legs and movable joints. A dog would be classified as a tetrapod.

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.

Did you participate in a class discussion providing evidence for your answers, and/or used the ACE strategy in your work?

Yes this week we did a google doc about classification and we needed to answer questions using a different number of sources.

Summary: This week we learned about how scientists find the common ancestor of an organism. There's actually multiple ways such as comparative anatomy and a cladogram. Comparative anatomy is when scientists check the bones of an organism and compare it to the bones of another organism. If they have a similar bone structure or they have a bone that's the same then they could both have come from the same common ancestor. A cladogram is similar except it doesn't just to bones it also does hair and embryos. A cladogram is similar to a graph and a scientist would use this to compare traits of multiple organisms and would see which organisms were most related.

SP4: Analyzing and interpreting data
Scientific investigations produce data that must be analyzed in order to derive meaning.

Did you create a graph, table, drawing, etc. of the data you obtained in an experiment?

Yes because we used a cladogram to see who was most related to a T-rex and we used a graph to record our data.
