This week in science # 5

       This week in science was really interesting and fun. We did many things, from launching rockets to studying crickets! First we had to finish our Rocket investigation which consisted on building rockets using straws as the bodies, index cards for the fins and molding clay for the nose of the rockets. It was really fun because after we did that we got to launch the rockets across the hall. Also we observed animal behavior videos on youtube, some of them were really funny. After we saw the videos we started to observe crickets and even tho they were nasty it was interesting to observe them.




      I learned a lot this week both from the rocket investigation and from the crickets. One of the things I learned from the rocket investigation was that wings and weight of the nose ( tip ) of the rocket really effected how far it went and that was really interesting because during our research all the articles we read said that wings didn't effect the distance but the stability of the rocket. Also while observing crickets we saw many things. One thing that was interesting was that our crickets weren't chirping and a lot of our class mate's crickets were. I wonder why our crickets didn't chirp? Also there were a lot of dead crickets in our container with the crickets, I wonder what happened to them? This week in science we did and learned a lot, but I still have a lot of questions about some things.

This Week In Science #4

                             This week in science we did and learned many things . One of the things we did was that we finished our plant investigation . We also started planning our investigation write up and we created the list for our project planning that helped us figure out what we had to do . In our investigation write up i had to write the hypothesis , draw the experimental set-up and write the variables . Something that we realized this week in science was that when you conduct an investigation the investigation ether our data collected supports or doesn't support our hypothesis , not that our hypothesis right or wrong . 

                                  This week we also learned how to do many things . We learned how to set-up an investigation write up with out an outline and what we needed to have in the write up . Also we how to write a conclusion even tho we didn't get to finish them . Also we learned what graph was best to plot our data and the graph that best suited our data was a line graph because  we were measuring the growth of our Brassica rapa in days . We spent most of the week doing our experiment write-up and we learned a lot about it .

This Week In Science #3 .

     This week in science we did and learned many things . Some of the things we did was we looked at our plants and we recorded how much they grew since the day we had planted them . I had to draw pictures and record their measurements . We also wrote our testable question and our hypothesis. During our data recording we discovered something that proved my hypothesis to be false . I realized that even if you planted the seeds of the brassica rapa deep in the bottom of the cup it would still grow . This week we also wrote procedures of how to make peanut butter and jelly sandwiches so we could we ready to write our procedures of how to collect data for our plant investigation . The last thing we did in this week was that we went around the room and surveyed people on their favorite basketball team and created a circle chart with the data , the chart didn't come out as planed though .

    This week we also learned many things . One of the things we learned was our driving question and what we needed to know , like the " if ... then ... because " format . During our data collecting we also learned that if you plant brassica rapa seeds at the bottom of a cup it will still grow at almost at the same speed of the seeds planted in the middle and top , that was very interesting . We also learned how to make good procedures for our plant data collection and how detailed we had to be . During the time when we surveyed the class about their favorite basketball team we also learned many things . Some of the things we learned was that we should have only have a few teams instead of giving people the option to chose any team because it was really difficult for us to graph all the data collected . We did and learned a lot this week , and what we learned will help us in the future because we realized many things that where small but effected what we did big time .

This Week In Science #2

This week in science we did many things . We did many things relating to our second plant investigation. First we did an observation on poppers and how the the way the looked effected how high they went when we popped them . Then we did research on the plant called Brassica Rapa . We also did a lot of things relating to independent and dependent variables . We created questions about the Brassica Rapa and we created an experimental set up for the plant investigation . Lastly , after creating the setup we planted our Brassica Rapas and that's what we did this week in science.

            We learned many things this week in science . We learned how variables effected the results of an observation . Also we learned a lot about the Brassica Rapa . We learned that the Brassica Rapa is a fast growing plant used for many things , such as food . We also learned how things like the amount of water to give to a plant , the amount of soil , the number of seeds , how much sunlight and how deep you plant the seed can effect the growth of a plant . Things that can be changed in an investigation are called independent variables , and that what is effected by the independent variable , such as how tall the plant grows or how fast it grows is called the dependent variable .
