This week in science #3

1) This week in science we our driving question was "How can we as scientist, conduct and publish a plant investigation that satisfies all the NDHS requirements and get us an A?" We did a list of things we needed to know about being graded. My groups testable question is "How doe the amount of light affect the Brassica Rapa's height? Our hypothesis is "If the amount of light changes then Cup B and C will not have any color because of the lack of sunlight. Throughout we did some observations and drawings from our plants.

2) This week in science David gave us a rubric. I learned about the requirements I need to fulfill in order to get a good grade in this investigation project. On Tuesday we learned more about hypothesis and procedures. I learned that our procedure has to be thoroughly written in order for everyone to be able to follow it. As for our hypothesis it is suppose to be written in the if-then-because format.

This Week In Science #2

1) This week in science we played with poppers and began our second plant investigation. On Tuesday we played with the poppers and did some observations. Some of the poppers were small and some of them were really big. We talked about dependent and independent variables. Then the next day, Wednesday, we planted brassica rapa in three cups. My groups question for this plant investigation is "How does the amount of light affect the brassica rapa's height?" Our independent variable is light and our dependent variable is the height of the brassica rapa.

2) This week in science I learned about the brassica rapa. The brassica rapa is a dicot. It has several different names it can be identified as. The brassica rapa grows better in moist areas and well fertilized areas. The brassica rapa is also used as a remedy, folk medicine. People believe it helps in curing breast, and skin cancer. To be used to help you have to boil the roots with lard. It is also occasionally suspected for poising pigs and sheep. I also learned a few things about the poppers. You can change the independent variable and that will affect and change the result of your experiment.
