Trees at AES

Partner Tree

My tree is the eucalyptus tree. It is particularly the Forest Red Gum. The scientific name is Eucalyptus tereticornis. The Hindi common name is Nilgiri or Safeda. It is a tall tree, and according to the book, it is approximately 22 meters long. The leaves are long and narrow, and are often curved.  

 
The fruit looks like this-

Overall-

  

There are a total of 3 Eucalyptus trees on the campus. Two of them are in the ES playground, and one is behind the tennis courts. 

Notebook

A complete entry will have seven things-

  1. Class Notes
  2. What we did
  3. What we saw
  4. What we talked about
  5. What you think/wonder
  6. Picture
  7. Sketch

Best Notebook Entry

Typical Notebook Entry

Worst Notebook Entry
I have realized how important these entries are. They help us keep a record of our learning. If we forget something, we can always go back and revise it. My best entry is the one with most detail and depth. My typical entries are detailed but not as much as the best. I always have a lot of photos in my entries. One thing I don’t have a lot are sketches. Only a few of the entries have sketches. Also, I don’t categorize everything. It’s kind of like paragraphs with everything in it, because they connect so well, that it makes more sense to put it together. My worst entry is an incomplete one.

Science Reflection

Reflection:

A. Provide several sentences about your learning in science this year. Be specific. These should be things that you would like quoted as a part of report card comments about you.

I think my learniing is increasing steadily. In the beginning of the year, I knew nothing about motion. I had never  even thought about it. But now I know incredibly more, if you compare it to the time limits. I know what speed is- distance over time. I know what force is- it is the cause to accerrelation, change invelocity  and motion. I know veloccity is adding direction to speed. Also, accerelation has three parts to it- speeding up, speeding down and changing direction. According to the time constrains, I think I have learned a lot.


B. How are you making sure your assessment project is complete and that it meets the criteria (standards). Be specific.

I will refer back to the science summative document , and check if I have all the standards in my product. I will check off a standard if I have explained it completely annd properly. Then I will work on the remaining standards.

C. What would you do differently in your assessment project if you were to start over? Explain.

Brainstorm what could be some possible variables that could affect my data, such as the floor. Then see what can be done so it doesn’t affect my project.

D. What would help you become better at planning and implementing your own independent investigation?

Putting deadlines for parts of the investagation. Such as, Brainstorming for the first class, finishing my data by the 1st half of the third class, starting the making of  my product by the 2nd half of the third class, submitting the final product before the fourth class.


E. How important is it to you to become good at independent investigation and thinking?” Explain.

I think this is an important part of science that I still have to experience more. I usually prefer to work ith a partner because it helps get accurate data and different points of view. But independent investigation is essential because, you will not always have a partner to help you. At one point of an assessment, you have to do by yourself, when you explain your thinking and make your product. I think I have experience with this part of the investigation. But I don’t have experience with  brainstorming or gathering data by myself.

Rocket Launch Summary

  

  
This is my rocket launch poster. The larger trail of the rocket is a typical rocket launch. I explain the exponents of motion in the launch. First of all, we pumped air in the rocket as shown. We put a force into the rocket. Later, it moved without a force, this shows inertia. How an object can move witthout a force applied to it. This goes back to what we learned from the cart experiment. Next, another way force was applied can be told by the change in direction as shown by the steering wheel. Force= mass times accerlation. Accerlation can be seen in three different ways- going faster, going slower and change in direction.  The force caused a change in velocity.The rocket was in an inertia movement as indicated by the dots on the trial was disturbed by an unbalanced movement, a force.  An example of newton’s third law of pair force or action reaction is shown as gravity. The rocket is pushed upwards by the force pumped into the rocket. On the other hand, the force gravity, is pushing it down. They are meeting each other from the opposite side with force. Finally, I drew my rocket launch, which was all tumbly.

Motion and Tumble Buggy Reflection

I think that you can fiind the average speed by taking several trials of a track by one angle and average the  numbers. Then you take measurements from another angle and average those. Then you average both numbers you got. Divide it like this- distance/time elasped [average time]. Whatever you got as an answer is the average speed. I found out that my Tumble Buggy had a constant speed. It maximium varied by 1/100 of a second. I found out because the graph showed a pretty straight line throughout for all the trials. I am most proud of the fact that I understood what I had to do and If there was any confusion, it got clear today. I feel that way because the document was pretty clear and all the confusion was cleared by Dr.F. I think the hardest part of the experiment was when Dr.F told our group that to find out how constant the speed of the Tumble Buggy was because at first I thought that what I did was enough and then I got to know it wasn’t enough. I thought I had my answer, but it got proved wrong after doing more measurements. My biggest struggle with motion has been to understand when to use the mean and when to use the median because different questions require us to use different types of averages. For example:- In the Tumble Buggy project, I think we should use the mean, but I wasn’t sure if it was the right answer. i don’t even know if there is a right answer. I had never thought of motion as distance and time and speed, I had always thought of it as only movement. I think this was the root of the difference in my thinking. The main thing I have learned is that time and speed are similiar but not the same. I thought of them being the most important thing because that was 2/3 of what are unit was about- Time and Speed. #Tumble Buggy
