This week in science we learned many new things. In class there were different questions asked, questions that were harder to answer and we started to pick at a new topic. Then at the end of the week we had a quiz and that wrapped up our week.
Question 1:“What are some characteristics of life?”
Well some characteristics of life include, able to reproduce, growing, breathing, respirate, display heredity, and needs energy. Also going along side with this question is that we did an experiment to test out our thinking’s for living and non-living this. We tested objects such as apples, seeds, and exo-skeleton, and a flame. Our tables had tot determine which were living or non-living. Sometimes our thinking was different from other students in the class, so we had to check out the object a little more to prove our point. Figuring out which objects were living or non-living was quite difficult until we added another category which helped us organize things a little better. I didn’t realize how difficult it was to notice if something was living or non-living until I did this experiment with the class, and learned that you can never tell if something is living or not by just looking at it.
Question 2: “Why is it so hard for all of us to come to a conclusion if something is living or not living?”
We all have a very difficult time putting these items into different categories because we all interpret things differently and all have our own ideas and opinions about things. This makes it much more difficult since we all can’t come to one conclusion since we all have different ways of thinking. Another conclusion that I can make is that our class is very ambiguous, when, discussing things like what we were talking about in class and shows that we are all very opened minded.
Question 3: “How does a hypothesis differ from a prediction?”
During this week we touched a strong point on the topics hypothesis and prediction. Hypotheses show more information and are based on an observation. They are also testable, very general as in not specific and can also be incorrect. Predictions on the other hand need a hypothesis and are based on a hypothesis, just like a hypothesis depends on a prediction. This shows that they rely on each other, but have different things bout them which makes them different from each other. Predictions also have a test to back them up, very specific, and always are correct. Both hypothesis and prediction re very different from each other, very opposite, but will always have to use during an experiment.
Lastly we started to look at the Community Heath Department concern. This was a list of schools that had a huge number of students out per time and needed to figure out what was going around and how they can prevent that. We are still working on it and will hopefully get some more reports from Mr. Seagan soon.

this week i learned about different sicknesses like diareahal disease and malaria. These sicknesses are mainly caused by the spreading of germs or feces. You can catch the disease, malaria, by getting bitten by mosquito that has that disease so now the sickness is running all over your body. Other than learning about sicknesses we learned about independant and dependant variables. A dependant variable is a varible that changes according to how your expirement turns out and an independant variable is a variable that you change durin your experiment. This week we learned many more things and I cant wait to learn more next week!!
