We have spent the last week or so doing our first experiment. We did this to learn for ourselves how scientists work.
Now that you have completed this experiment, it is time to look back and think about what you have learned. Look over the following questions and then write a two to three-paragraph reflection that answers them. This is to be done on your own.
- What have you learned about how scientists work and the methods they follow?
- Why do you think this method would add to scientific knowledge?
- What would you do differently next time in terms of how your group performed your experiment?

Something’s I have learned about how scientists work is that they follow the Scientific Method. The Scientific Method consists of steps that are followed during an investigation to make sure that the information gained during it is accurate and true. This is how the Scientific Method works…
1) State a question or problem
2) Make background research about the topic that is already known.
3) Create a hypothesis-an educated guess based on background research.
4) Create a procedure to follow during your investigation. This is to test the hypothesis that you made in step 3.
5) Record your results
6) Make a conclusion on what the results (data) means.
7) People in your group compare (review) results.
The Scientific method they use is useful because it gives them something to follow during the investigation. The Scientific method adds to scientist’s knowledge by keeping them more organized by following a procedure and teaching them new terms such as, “hypothesis”, “inference”, “observation” etc.
Something’s that I would do differently in my group if I were to do the experiment a second time is research planes a little deeper. Our planes did not fly far because we did not have enough background knowledge or research (step 2 in the scientific method) to know how to make them or know why some planes fly better than others. But I think it was a fun experiment and I would do it over again if I could.

I learned that scientists always have new methods of finding out new things. Whenever they test something they use a hypothesis, state a question or a problem observations, inferences and a conclusion. A hypothesis is an educated guess. An observation is when you look at something and take notes. An inference is guess about what is going to happen next. Scientists always use this method.
The scientific method is important because they have something to follow. When they use hypothesis, observation or any method it will keep them organized.
We could of done a couple stuff different like we could of used heavy paper because the wind controlled it and it would turn around and go backwards. We could have been neater because the planes were everywhere.
p.s. Are we going to fly the planes out side?
I learned that they have hypothisistes and observations and a lot of test's and they also have conclusions.
It would add to scientific knowledge by giving all the information you need to find out the things you need to.
I would have made more planes and try to work on planes my partners are making to improve them by making my own copy.

I have learned many things about scientists through this lab. One thing I learned about scientists is that they hypothesize. They also observe, infer and predict. We made a hypothesis about which plane we thought would be the best, using our own definition of best. Then we tried different designs and observed them to see which three would be the best. Something else I learned is that they follow the scientific method. The scientific method is a procedure followed during an investigation to help them make sure the information gained is correct and true. Scientists do these things in order to work correctly.
I think the scientific method adds to scientific knowledge because it shows scientists how to do things in order to get the right information. It helps them determine between true and false information. Also it helps them build their knowledge the correct way.
There are a couple things I might change, if I were to perform this experiment again. One thing I might change is the way I folded my plane. I might make a larger flap on the bottom of my plane, because I observed that planes with larger bottom flaps seemed to stay in the air longer. I also might make crisper folds, or maybe fold up the wings. Another thing I might change is the number of trials. I would either only do three trials, because the plane would not get as damaged or maybe even go up to seven trials, so I could try different ways of throwing. Those are the only things I would change.

I have learned that scientists do a numerous amount of things to show how they think and work, but something that they use all the time is the Scientific Method. This is how the scientific method works:
1-conduct a problem
2-make a hypothesis (one that makes sense) about what you are researching
3-make a procedure to follow while investigating your hypothesis
4-always take notes about what you learn!
5-run tests on your ideas and collect data from the tests
6-see if your hypothesis is correct
7-make a conclusion depending on your data and on your hypothesis
I think that this method is helpful because if scientists didn’t have it, they would probably get confused or be disorganized. They would have to have a lot of scientists with them so each one could think of something to test and or learn about. But with the Scientific Method you can take things step by step in an organized and easy way.
I think that my group performed our experiment well, but I think that we should have tried out more planes and researched more about the planes. But other than that I think that we worked well together and listened to each others ideas.
I have learned a lot about how scientists think and work. They strictly follow the scientific method because it instructs them exactly how to find the facts about the universe. They usually follow every step of the scientific method, from realizing the problem to communicating their results. I think that the scientific method is perfect to add to scientific knowledge because the way it is constructed proves everything right and wrong if it's done the right way. I make a lot of paper airplanes, and I know a good design for one, but I didn't stick to it, and experimented with different kinds. I think that I should have stuck with my old design. Even the scientific method says to make background research and use that.
My Paper Airplane Reflection
This week in science class we worked on a paper airplane project studying scientific methods and how scientists work together with kids all the way in Australia! Methods are steps that are followed up on to make sure all the information is accurate and as true as possible. The steps are simple you need to have a question, hypothesis and a conclusion. Scientist also investigate to answer questions and problems they may have.
The scientific method adds to knowledge in many different ways. If you ask a question instead of just looking at something you need to observe to answer that question you can learn a lot more because that leads to more questions coming up which also leads to more answers. If you have a hypothesis you strive more to prove it and defend it so you try to find out as much information as possible. Then if it’s wrong you make a new hypothesis and the cycle starts all over again. The conclusion of a problem can lead to even more questions that start the cycle all over again. Basically the scientific method helps develop questions which then need answers and that’s how the scientific method can help you learn.
Paper Airplane Project
I had fun constructing and testing paper air planes. I have a plane at my house that took 3 books and 2 websites to join all the types that I call the Cheetah. It flies accurate and fast for roughly 30 feet. I wish I could do the experiment over so I could enjoy it again. I loved the fact that we learned the scientific method in a fun way I learned a how to make a great plane and had fun.
From this project I learned about scientific inquiry and the scientific method. Scientific inquiry refers to the ways scientists investigate the world. Scientific investigations are done to answer questions and solve problems. The Scientific method is the method scientists us to solve problems. The Scientific method goes in this order:
1. State the problem
2. Do background research
3. Construct Hypothesis
4. Do experiment
5. Analyze data
6. Draw conclusion
7. Report results

The Airplane lab
The airplane lab was both fun and a learning experience. This lab
helped me understand the scientific method better. I now understand what role each part of the scientific method plays . In the beginning of my experiment I created a hypothesis after I collected my data I accepted my hypothesis. In the end the Avenger flew the farthest out of all the planes. There were many parts to this experiment. one of the first steps was to find background research this helped me understand more about paper planes. The materials I used in the experiment helped me find my data. In the lab I used paper and scissors for the planes and to measure I used a tape measure. One of the most important parts of my experiment was to collect my data. In my data it shows the distance the planes went in every trial and the average distance of the plane, this data helped me with the rest of the experiment. After I collected my data the next step was to compare the flight distances of the paper planes I used a graph to do this. The last step of this experiment was to draw conclusions to summarize what I learned. I think that this experiment was easy and helped me a lot. If I was to further investigate this experiment I would have more trials and more paper airplanes to see which one would go the farthest. This experiment helped me understand how to set up a lab report better. In this experiment I learned that scientists work together and use the scientific method. The scientific method ads to scientists knowledge by making them think of all parts of there experiment. If I could go back I would spend more time on the design of the planes and make them go farther.
Airplane Reflection
The things I learned about scientists and their thinking/method Is that really only the experiments are fun. I guess the lab is necessary for keeping track of notes and whatever other stuff happened in the experiment. I learned that you really do have to test a lot of variables before you can really be sure that your hypothesis was right or wrong. I also learned that you might have to change certain things in the actual experiment to get good results. I think this method doesn’t really add much to the experiment or science because you are going to get the same results whether you do it in the perfect form or just right down your results. You don’t have to right down what you think will happen and the same thing for conclusions. That’s just my point of view though.
If I could do this experiment again I probably would have done it a little more in depth. I would’ve tested more planes and done different things like how far it goes, the accuracy and the smoothness of the flight. My group worked relatively well together except for a select few who had trouble interacting with the rest of the group.

I learned that scientists use observing, inferring, predicting, and making a hypothesis as their methods. They work by making experiments to test their thinking and work.
I think the methods they use would add to your knowledge because they all add up to answer your experiment or problem.
I think that next time I do an experiment like this I would take more time to make better planes. If we test fly them and they work DO NOT adjust them or fold more.
Airplane Lab
Scientists follow the scientific method wish is the steps you follow to get a scientific answer.
1 Start a problem or question
2 Get background research on the topic
3 Make an educated guess or hypothesis.
4 Come up with away to test your hypothesis from the step above
5 Record results and repeat step four to find an average
6 Come up with a conclusion and share it to the people of the world
I think it makes getting answer easier. It tells you what steps to take to get the answer to your problems. If I could do anything different I would test to see if the type of paper affects the flight of the airplane. I think that the heavier it is with the most thrust will go the father and stay in the air long than an airplane with lighter plane with less thrust. I think that it would go father because the lighter one will just float to the ground.

Paper Airplane Lab
Through this lab I learner about the scientific method and how scientist think and work. They follow the scientific method so the can solve questions through making models, making hypothesis, predicting what will happen next. They also make observations and inferences from what they see and from what they know. They also have to list the procedures they will take.
I would think that the scientific method would improve or help our well being of life. I think this because we actually do these things on a regular bases. For example, there are nine lines of words so far in this essay. See That is an observation. An inference would be this essay will be longer than fifteen lines of words long. There you go already I’ve used two of the seven different steps of the scientific method just in this essay.
Next time I would do this experiment would be to test and see if the longer hang times effect the distance of a plane in it’s flight. Also I would see if I could figure out what made the plane fly so far and see if I could use that to make an even better plane. Also I would try more types of planes in this test to see if their shape effects the flight..
I have learned that scientists have to work really to achieve the result that they are looking for. Scientists have to follow the scientific method in order to do a controlled experiment. The scientific method is a list of steps that ensure that your experiment is controlled. The steps go in this order
1) Conduct your problem. In other words, recognize your problem.
2) Make a hypothesis based on what you already know. It has to make sense. It is an educated guess.
3) Make a procedure. The steps that you are going to need to follow to test your hypothesis.
4) Record all of your results form the procedure.
5) Make a conclusion including whether or not your hypothesis was correct or not.
The scientific method is useful to scientists because it helps them to stay on task
by following steps which are sort of like instructions. The method keeps scientists organized in all that they do. If I were to become a scientist when I grow up I will definitely follow the method.
Next time if our group did the same experiment I would make sure that everyone
agrees on mostly everything and it is not majority rules all the time. I would do this because there was always someone in my group who didn’t agree and I don’t think that that was fair to them. I would also make sure that everyone knows exactly what to do before we start the experiment because sometimes we would all be confused and no one would know what to do. Also, I would make sure that everyone is on the same page in their packet because it is easier to work on it together that way. Also, you can compare your answers with each other instead of waiting for certain people to catch up. The last point is that I think we needed a little more background research and more thought about our definition of “best”.
I have learned that scientists have a method in which they do experiments called the Scientific Method. They do many things before actually doing an experiment. First scientists make a problem that is in the form of a question. For example: ‘Which airplane will stay in the air the longest?’ Then they make a hypothesis or educated guess about what will happen. Example: ‘I think airplane A will stay in the air the longest because (very important) when we did a pre-test it seemed to be the best.’ After you have done these things then you get your materials and do the experiment. While doing the experiment you must make observations and inferences so you know what happened in the experiment. After you have done the experiment and made observations and inferences you must make a conclusion which is where you answer the question to your problem. Example: ‘Plane B stayed in the air the longest.’
This method adds to a scientist’s knowledge of the experiment because it shows the scientist how they did the experiment and how they solved the problem and basically everything that they observed and thought about the experiment.
Maybe if we had a little bit more space, our trials would have been slightly more accurate because sometimes they hit a wall or people, and sometimes we had to wait a couple of minutes before a person could move and we could continue with our experiment. A suggestion that I have is maybe only one or tow groups go at a time so that everyone has enough space.
I liked the air palin project because i love flying air plains and i like seeing them doing tricks. I liked working with my friends and makeing design plains with them.

Working in the fields of science can at times get quite complex; scientists need a process to help them solve the problem. When scientists need to find out why things happen the way they do, they are said to use a scientific method of thinking to help them along the way.It is a process that includes steps that are followed during an investigation. Some of the steps include a description of the problem, observations, inferences, a hypothesis, experiments, variables, and a conclusion to finish.
In 4th period science class we conducted an investigation to find a paper airplane that would produce the “best” results. First we had to find out what our definitions of best would be, in our case best meant smoothest flying. Along the way, we followed the scientific method of thinking to help us succeed.
This method adds to scientific knowledge and is vital in order to conduct investigations properly. It makes sure the information you gain is accurate and true. Instead of writing down facts, sorting everything in your head, then trying to make something out of it, you can organize your thoughts by follow each step in the scientific method of thinking. I learned that it is vital to complete each step entirely in order to get closer to the answer you seek.
I learned that scientists collaborate on thinking up ideas, making plans of action to test their ideas, and participating in experiments. Scientists are always juggling questions to guide what they are doing. They recognize the problem and use information that they already know and make perceptions using their five senses. They make conclusions about their observations, make testable explanations from the details they observe, have things that change during the experiment, and compare their results to their hypothesis.
If I were to do the paper airplane lab differently, I would have more variables during the experiment to really verify which is truly the smoothest flying plane. Some variables would be including how straight the plane flew (using measurements), how swift and slow the plane descended and if the plane was shaky as it glided.

Last week we did a experiment on paper planes. In the experiment we had to think of a name for our group and think of what our definition of best was. My group was Dani, Ellen, Nadia and I, our name was We Fly Like Paper Get High Like Planes and our definition of best was: a plane that stays in the air for at least two seconds and goes in a forward motion.
One of the most important things I learned about how a scientist thinks and works is that they use the scientific method. The scientific method is the way that scientists solve problems, the method goes in this order:
1. Identify problem
2.Make Observations
3. Make Inferences
4. Hypothesis
5. Experiment
6. Variable
7. Conclusion
8. Scientific Theory
9. Scientific Law
The scientific method is helpful because its easy and organized without it scientists would by disorganized and very confused.
My group worked great except we didn’t try out as much planes as we could and didn’t research a whole lot. Also someone in my group flew their plane upside-down so that effected our tests.
Airplane Project
Scientists should follow up on the scientific method because it gives you something to follow. All you really needed was a question, hypotheis and to conclude the project when your done.
The sceintific method is important because you test not just one thing you test about each one a few times so if you accidentally get a really bad flight that won't be it, because you have more tests.
We should have been able to add weight so it could go farther, and smoother paper.
AIRPLANE LAB
Many scientists use a scientific, method which is:
1-start with either a question or problem
2-use background research on your topic
3-make a hypothesis (educated guess)
4-make a procedure that follows the steps you used in the following step
5-record your results and find your average
6-create a conclusion based on the information you have
After you have done all of these steps, go over them with your group members.
I think that that if we did this experiment a 2nd time, I would want to do some more research on flight history and what shape's and size's make paper plane's go farther.
