Plant Observation #3

Pollination

 

In the past 2 weeks my class pollinated are plants. If you pollinated a plant that means that you carried pollen from your finger onto hopefully onto the stigma which is the sticky part of a plant and when pollen and pollen mikes you get a seed!Knowing that my class found out that when we pollinated the flowers fell off and the stem got thick. Why do you think that happened? Well that happened because the stem is storing the seeds in the stem and the flowers are falling off because the plant already reproduced so it has no more uses.(This is my controlled plant the manipulated plant is totally dead.) Also if you want to pollinate your our plant all you have to do is touch each one of your plants to pollinate them. And there are ether pollinater’s ether than use, bats pollinate, ladybugs pollinate, hummingbirds pollinate, bees pollinate and even butterflies pollinate isn’t it cool how all these animals help the world and we don’t even know?

Manipulated

My groups plant manipulated is doing so bad that we just today threw it out in the trash. I thought why was it doing so bad? Could it be with the notes about it? I looked at the notes and I saw that on 5/19/17 it was ¼ of a inch tall, the soil was dry, 4 leaves and orange sproot but on the 22 all the plants were gone! It’s like someone stole all the plants in that quad (that were we put the plants in it’s called a quad because it has for sides and quad means 4) but someone could not have stolen my groups plants but then how did it get missing? I think the sugar water did it because that did not happen to the controlled plant and my group just gave it water, so it has to be because of the sugar water but why would the sugar water do this to a plant,a plant reproduces on sugar though why would the sugar water kill the plant? It does that because plants don’t reproduce on normal sugar it reproduces on its own sugar called glucose.

 

Controlled

 

My controlled plant is doing great! But the weird thing is that on 5/23/17-5/25/17 there were some brown leaves but why. Well we know that in the fall the leaves change color so we got our solution but it’s not fall so why would the happen? Could it be too much sunlight, because when we get to much sunlight we get tane and that’s close to brown. But plants can’t get too much sunlight so why would some of the leaves be brown? I found out that in leaves there’s something called chlorophyll with gives the plants leaves the color green. And when it gets cold the chlorophyll runs out and so brown yellow and orange are the real colors of a plant.   

 

Prediction

 

My 1st prediction about my plant is that more leaves would fall off because I already pollinated our groups controlled plant and because I used to have 24 leaves but now I have 5 leaves left. My 2nd prediction is that the stem will get thicker because the plant is going to make more seeds if not already done. My 3rd prediction is that my plant is going to grow even more if we replant the plant because it’s a brand new fresh seed and because the plant was doing good and it is healthy. My 4th and last prediction is that my I think plant will start having wet soil because it has been happening for the past 3 days.

Plant Observation #2

My groups controlled plant is growing so much through the past weeks. My last post was about the things I saw 2 weeks ago, if you had not seen that, then read that 1st so the things I will be talking about will make more sense. Now back to my control plant, the plant grow so much more, the last time I checked the plant was 3 inches tall! last time it was only about 2 inches tall. And all the plants looked healthy but 1 of the plants had light green leaves and all the rest had about a good amount of shide with the green color, and when I looked at other groups controlled plants it was again a good amount of shide with the green color but 1 groups plant it was just like my groups plant. But why I think it’s because we might have gave it to much water but wouldn’t  that make it a darker color? Well actually I think it can make it lighter or darker depends on the plant. I still don’t know what it is but when I know I will write about it! My groups manipulated plant is still doing bad, it grew a little bit more but still the bottom line is that it needs real water not water sugar water. Right now the manipulated plant is about ½ of an inch tall,but are controlled plant 3 inches tall,the manipulated plant is nothing compared to the controlled plant. Now about the color, on of the plants that hadn’t grown yet  (I think that’s because there is a stick sticking out of that says M for manipulated and I thank it affected the plant not to grow till this week) it is right now orange! Now again my group looked at other groups but this time no group had what my group had. So we know that the sugar water made that happen but why? Well, we think that plants make a different kind of sugar but we don’t know. And there is one more observation that I will like to tell you, the observation that I will like to tell you is that for the manipulated plant and the control too most of the the days the soil was dry, I just wanted to throw that out to you, you probably were thinking it was going to be something big, but, sorry! Well if you’re still there I think that I have nothing there left to say so I hope you liked this essay.

Plant Observations #1

My class split on into groups but you only go with people the want to do the same experiment as you. The experiment that my group did for our plant was that instead of putting normal water my group is putting sugar water. My hypothesis is that the plant will have more leaves than with plain water. We thought that because plants reproduce on sugar so why not give if more sugar. Will the plant make a difference?

 

I found out that it does make a difference if you give a plant sugar water vs if you give the plant regular water. It actually made a big difference. The difference was that the control grew so much leaves, I thought that the control was going to be better than the manipulated but the next day I saw the manipulated had some growth too. It was 1/4 of an inch and it was growing in a straight line but it did not grow enough to beat the control. Today I saw a sprout on the manipulated one and it was purple, why is that?

This is the Control (it grow so much more, this photo was taken on May 8, 2017.)

This is the Manipulated (sorry there is no purple sprout and it’s because this this photo was taken on May 8, 2017, sorry.)

Fidget Spinners

Moms and Dads you might be thinking “what are those spinners and how are they cool?” If you read this, you will understand that those things are called fidget spinners. Fidget spinners are so cool and fun because it just feels good to use one. If you have a fidget spinner  people will think you’re cool. People will ask to use your spinning and you start being nicer as a person. Let me explain, your kids will start to let ether use it and they can make friends. And I think you want your kid to make friends right? So buy your kids Fidget Spinners now. (Mom and Dad get me a spinner!)

Maglev Reflection-Day 2

On day 2 my group’s train levitated! It was the greatest thing ever! We put marbles in a cup on the train to see how many it could hold. At first it could hold 8 marbles while still levitating. To improve it we put magnets in the holes of the track and then the train could hold 21 marbles. But just because we got 21 marbles did not mean we did not try to improve the train.  We put marbles on the track because we thought it would make it go higher. But  we noticed that it made friction. So we were about to take it  out but we had to clean up. And that’s all we did on day-2.

Maglev Reflection – Day 1

When my class was learning all about maglev trains, my group was hard to cooperate with because one everyone wanted to do there own idea because they thought that there idea was the beast. But then we go the hang of it and we started to work as a group and not like someone was doing all by them self. A nether hard part was when put the strip magnets on the foam board and when we put the strip magnets in the box when we wanted it to levitate the box was to small so we were about to cut the foam board to be smaller but we were out of time. Next time we work on the maglev trains I think my group would want to finish cutting the foam and see if it works and we’ll see it it works.

My Expert Book Reflection


My teacher Mrs. Mangan told my class to write an expert book . I thought I would do mine on hockey, but I did mine on the Brazil soccer team because I did the starting of unit one on hockey so I wanted to switch it up. And it’s easer said than done. There were lot’s of hard part’s of writing an expert book. For example chapters were hard and the hardest chapter were:

  • All The World Cups Won [For Brazil.]
  • Into
  • Top 5 Players Chapter

So if you won’t to learn about the Brazil soccer team read my book!
