This Week In Science 3

This week in science i have been recording on how my plant has been growing and one of my plant hasn't been growing because it was part of my experiment. One of my plants had to get more than enough water to see if it still grows and lately it has been growing, but slowly. I also got a assigned a driving question and that question was how can we, as scientist, conduct and publish a plant investigation that satisfies all the NDSH requirements  and get us an A? With this question can many more questions like how can we achieve the answer to this question and others.Also, David gave my team and i a mission questions and we had to answer this question, make a graph, and explanation in like 40 minutes 


This week in science i learned what is the if.. then.. because.. format of NDSH. I at first i was really confused but then when it was explained to me it was real simple. Also i learned that when you need to do a procedure in order to get a really good grade you need to explain the step in depth. It needs to make so specific that even a 5 year old or and alien from space that can speak english can do it. I really didn't know it had to be that specific, but now i know better.

This Week In Science #2

This week in science i was "playing" with poppers. It was kind of interesting because there were many types of poppers and they all acted differently. David reviewed independent variables and dependent variables with us. I wrote done the independent variables we can change to get a certain result. Also i did some reseach on the fast plants (Brassica Rapas). My team and i also did a plant investigation experiment setup for the Brassica Rapas plant and rew out the way the cups look.


This week in  science i leanred that even the smallest things can cause a big difference. I say this because when i was playing with poppers i notice that the smaller poppers didnt jump as high as the big poppers and they also dont make the same sound. I also learned that the Brassica Plants can be pressed for oil. I was amazed by this because the plant is very thin and the fact that it has oil in it i questioned myself how many of this plants can produce a gallon of oil.
