This week in science #3

This week in science we continued to investigate Brassica rapa and we investigated its growth.We saw that it really is a fast growing plant.Since we made a hypothesis that if we put different amount of water in each cup,then there will be different heights.The plant that got the most drops of water got the shortest height.The plant that got the least amount of water got the tallest height.It was strange that it was completely different from what we thought.                                                                                                                                                                                   I learned that Brassica rapa is indeed a fast growing plant.It has only been 5 days and it already has grown 5 centimeters.Everybody had different hypothesis',so everybody had different results in there plants.

This week in science #2

   This week in science I learned about Brassica Rapa. Brassica rapa is a very rare weed.It is rare because it is genetically bread to have very unique characteristics.It was founded in the 18th century and was said cure cancer but was not scientifically proven correct.It was also said to poison animals such as pigs,sheep,and bovine.I learned that this plant is very rare that it cost a lot of money to buy only a couple of seeds even though it is just a weed.Me and my class are now going to plant the Brassica rapa seeds and watch how they grow.It is said to grow the fastest out of any plant.                                                          
 
   I learned a lot about Brassica rapa this week in science.I learned that Brassica rapa is very rare because it is bread by different kinds of seed.It is the fastest growing seed and can grow in 24 days.I also learned about the special traits and what kind of plant Brassica rapa is.I will learn more as my class investigates.Even though it is just a weed it is a very cool plant.
