This week in science

This week, we watched a Bill Nye movie on discoveries about DNA. We learned about scientists and discoveries. This helped because got to see how really good scientists did experiments. We did this for two days and than we got the DNA results. We matched the DNA strands and mine matched. That means that everybody found out that I "stole"m it. This was pretty realistic. Then we learned about cell reproduction. We took notes on that, and answered questions on the reading we did. We also learned about photosynthesis and cell reproduction.

DNA and cells

This week we went over the different types of cells. We also learned how to make a formula to put the DNA from our cheeks into. It is called lysis. We are trying to find out who stole Mr.Finley's moon rock. All that we found was a hair. We have to compare the hair's DNA to some suspects cheek DNA in the room. This can really help us to see how people solve crimes. We also did a simulation on the computer on how to test DNA. We did this so that we can compare it to the hair and the criminal.

This week on Monday we talked about our graphs. We talked about the growth parameter and the population. We did this because we need t know what we are comparing. on Tuesday we learned how to write out explanations. We write explanations so that we can understand what we are learning. On Wenesday we learned the different concepts for each of the cells organels. We know the organals, but we need to know what they do. On Thursday we learned about the cells again. On Friday we started learning about DNA. This stands for Dioxyribose Nucleic Acid. We are learning this because it relates to the cells DNA that is conained in the nucleus.
