Science Lab Report Reflection

Introduction

For year 6 standards the goals that I have chosen include; exploring reversible (Freezing, Melting etc.) and irreversible changes (Burning, Rusting etc.) And also how when doing science altogether you have to use predictions and gather data and using that evidence to make explanations of events. And for year 5 & 6 standards I chose; to plan appropriate investigation methods to solve problems and answer questions. And also describe which variable should be changed in fair tests and accurately observe, measure and record data, using digital technology when appropriate. This term I have learnt about the 5 states of matter because I didn’t know about the state of plasma and Bose Einstein Condensate, which was very interesting. I also learnt about how the particles move in the 5 states of matter and the properties of other materials within the 5 states of matter. A molecule consists of a nucleus consisting of protons and neutrons and electrons travelling around it, and also consisting of elements of the periodic table to make certain elements. How properties influence us how we use certain things in certain ways. I also learnt that D=M/V which is very useful when working out scientific explanations. We also investigated melting and we conducted an experiment with variables to test this, we put cloth around frozen milk and hoped it would melt faster but cloth insulates the head coming from our body, but the frozen milk doesn’t have heat so it insulated the cold. Then we did a lesson on Deposition & Sublimation where I learnt about what deposition & Sublimation is and we found some examples of this and that sublimation is solid to gas and deposition is gas to solid. Then we learnt how Bicarbonate & Vinegar mix and this is the chemical equation; NaHCO3+HC2H3O2àNaC2H3O2+H2O+CO2 which are SodiumHydrogenCarbonDioxide3+HydrogenCarbon2Hydrogen3Oxygen2àSodiumCarbon2Hydrogen3Oxygen2+Hydrogen2Oxygen+CarbonDioxide, but what actually happens there is a whole other story and I got proof I understand it in my Goal Reflection. We also learnt about Rust so we soaked steel wool cloth in vinegar to act as a catalyst the rusting, rust occurs when steel is with oxygen and sodium speeds up this process, the stuff in vinegar, The chemical equation is Fe+O2àFeO2 which is Iron + OxygenàFerrous Oxide Rust. Then at Mt. Alexander College we did plenty of experiments that are documented in my book which would make this introduction unnecessarily longer. Then I learnt A LOT more from the other presentation from other kids and my presentations.

 

 

 

 

 

 

What I Achieved

During this term I have achieved have achieved a basic understanding of states of matter and how they work, throughout this unit I have learnt a lot and I understood it all. I have learnt about reversible and irreversible changes and this linking into physical and chemical changes. And I already knew that hypothesis, observations and evidence play a big part in your explanation but with this experiment I polished that off. I did use appropriate methods to solve problems and answering questions by simply conducting and experiment. We have tried to use different appropriate variables by trying to come up with 3 very different materials and this is an accomplishment, and I accurately observed data and measured it, but using digital technology I couldn’t really do because of our experiment wasn’t linked into graphs so it made it hard to use digital technology.  How I learnt about states of matter, reversible irreversible changes, physical and chemical changes, and all the extra fun stuff in between was with the lessons with Antony and the Mt. Alexander College Excursion.  Although how I learnt observations and hypothesis help with explanations, appropriate methods to solve problems, good variables and careful observations was from our research how and when we conducted our experiment and when we conducted our experiment. Although how I achieved the point in the rubric:Scientific Lab Report Rubric and it all happened in there:Scientific Lab Report but to recap we think we accomplished above expectations for planning and experiment and expected for the presentation.

Ways I Can Improve

Possible ways that I can improve from in this particular experiment is maybe make the presentation better because we had all the facts we just couldn’t share them with the classmates in an orderly fashion, and it was kind of boring and would’ve made the audience disengaged to fix this we could try to grab the audience’s attention with visuals. I could also research a bit more on the top and have more curiosity, like to explain more because something that happened in our experiment happened was the honey cube weighed more than the paint cube even though the paint sunk faster than the honey and this shows I could’ve found out a reason for this. But I thought of facts were good and the lab report was perfect.

What I Learnt About Science

I learnt that in science scientists have to make sure they are precise with all their measurements and their observations,  to make sure everything is correct and not flawed so they get a fair experiment and showing what actually happens. If they make a mistake then they have to do it all again and they have to make sure everything’s fair. So they get the exact result, basically they have to be EXACT & PRECISE.

 

 

What I Learnt About the Way That I Work

I learnt that the way that I work is that I work a lot on research and preparation but not all that much on presentation, which makes it hard to present. I also like to have a lot of research in my lab report and if there are any weird things that happen I am always curious and try to find out why. I can also drift off and sit there for a few minutes and not think about the task and maybe do something else and I don’t know why?

Goals in My Report

This really helped me achieve my goals in my report because mostly it was a science based goals and I am looking forward to the next 2 terms because they are all science based and I LOVE science and it’s my favourite subject apart from maths.

Prepared Speech Reflection

When preparing this speech I had no real difficulties, I already knew quite a bit about this topic from last year and I got opinion from other people. This speech was a matter of a lot of research and I coped with that very well I believe. Although a difficulty I did face was including all my important information and being able to fit it in to the time limit, and I am the sort of person that wants to go BIG, so naturally I tried to fit all of it. Also wording everything in an elegant matter and trying to make everyone understand the science was hard as well.

I think the strong points of my prepared speech was that I had a lot of research in it and that did the purpose of what a prepared speech is, to educate, and I think I did that very well, but this ended up with making more difficulties as well. I also I think I got fairly close to my time limit I got 2:40 and if I was aiming or 3:00 (which I was told I could do) or 2:00 (which was the average time limit). I had an average/adequate eye contact and my structure was good and my introduction was good although could’ve explained the science better and my conclusion clearly summarised all my points.

Although some things I can do to improve next time is that I can talk a lot a bit slower (I talked fast because of the length of the speech and the research), I could incorporate more public speaking strategies like transcendence, alliteration, etc. And I could also be a bit more enthusiastic and gripping to the audience. Like 100% I was enthusiastic about the topic but I can’t express that. And what I mean by gripping the audience is getting their attention so they listen and learn every single bit. And also something that may have happened is that I had TOO much research and not enough of what we’re trying to practise, public speaking, (Information was the majority and public speaking was the MinorityàInformation>Public Speaking). And I could’ve practised a bit more even though I thought it was fairly good it could’ve been better and I could’ve definitely of done that. And something else that was suggested to me was making props and graphs/tables which would’ve been good for my speech but I never thought of it and I can definitely do it next time.

5 Things that I thought I had done well was my research because it was most of my speech and I went very in depth into the facts and explained them, and there were a lot of facts that people may’ve had trouble getting their head around. I think I had practised fairly well, being able to speak the speech clearly but obviously it had to go fast as I explained before. I think my eye contact was adequate but not the best but I looked at everyone not just Antony and I did it often but I think that little bit more practise would’ve made it much better. I think I got fairly to very close to the time limit and this is always a good sign to a well-balanced, practised and structured speech. And finally my introduction & Conclusion was ace.

3 Things that you should avoid in public speaking is move from side to side from one foot to the other because this shows you’re nervous or unsure of something which will make people think of the speech a different way, but if you stand still people will think you’re confident ready to go and won’t even know if you are having difficulties or not. You should avoid having big cue cards that are hard to handle and you shouldn’t have them saying your whole speech but just a brief summary of each paragraph. And leave the cue cards down not right up in your face. Personally what I hate when someone makes a speech is when people pause, to look at the cue cards, put up a prop or they just forgot something because this affects it hugely, like if you’re stuck on a word but then you repeat the sentence or something, this just gets the audience even more confused about what’s going on in the speech.

The next time I present something I will try to evenly balance my speech form public speaking and Information because this speech was unbalanced and had much more information that the actual strategies of public speaking. I will also try to practise the speech more beforehand so I don’t have to look down a lot and it will make my speaking more fluent and ongoing. Lastly I would like to make better cue cards, make them a good reasonable size make them about of cardboard paper and hand-written and also I won’t put my whole speech on them, just a summary of each paragraph and practise will help hugely with that.

5/6C Graph Activity

data-for-graph3-1h8o55m–>Graph For Data

We had to turn a set of data  from AntsClass into a graph in excel, this was my results.

This graph shows the change of temperature per 20 years and how it is constantly fluctuating and rising more that dropping.

The reason that I chose this graph is because it shows change over time, this is why it is a line graph because that’s what the purpose of line graphs are. And that it shows very well how the temperatures are fluctuating. All and all this graph shows this information very well.

BTN Bionic Boy

http://www.abc.net.au/btn/story/s4473643.htm

From birth Riley was diagnosed with Cerebral Palsy and it is affecting his life, so Jordan has made an invention to try and make it a whole lot better.

Riley has a disability called Cerebral Palsy and it affects him in a huge way, it restricts him from doing everyday deeds and task as well as having fun. He has so much trouble he has to have a computer that tracks his eye movements which then types into the machine which finally allows him or more accurately the computer to speak for him; they have used the eyes as the mechanism because it is one of his body parts that he can control well. And this mechanism probably led onto Jordan’s idea of making this device, It’s a machine that allows him to control technology around the room using his eyes using left, right, up and down, and they describe it as a form of telekinesis, through this new invention riley has successfully turned on a lightbulb and soon with more practise a lot more technology. But Riley wanted to drive a car, so after a whole lot more engineering their invention was created, he was using left and right to steer and up and down to what I imagine to brake and use the gas. Although this led onto other troubles so he had sensors that hit his arm, telling him that he is near something. With all this Riley successfully drove the car, and this begs a question, what else will Riley be able to control with his telekinesis.

100 Word Challenge Week #20

https://100wc.net/

I was in the stables stroking my horse, buckling on the saddle and bridles, preparing it for a ride around the paddock. From the top floor I looked out the thatch window to see the town square crowded with people. But it all looked like clockwork, same movement from one place to the other by everyone. There was the palace as always standing tall, the walls strong ever and the watch towers, same old. I gazed at the city square as a whistle blew and everyone disappeared. Out in the distance there thousands of people full with spears and swords, and already huge stones were being hurled at the kingdom.

Prepared Speech-If Ice Was Heavier Than Water

Hello, 5/6C, hello Antony, Today I’m going to tell you about `if water got heavier when it froze`, first of all my topic is about what would happen if ice was heavier than water which it is not, ice will expand by the molecule links breaking and spreading, so that it is lighter in the end.

Last year we did an experiment and we froze some water the container ended up shattering because the water expanded when it turned to ice.

I will address one of the main points of this argument that I have seen on the web, would human life be possible, I believe that it wouldn’t although there’s other theories but from what I’ve seen the most people think human life wouldn’t be possible.

One of the basic things that will happen is that in cold climates the water will freeze and the ice would sink to the bottom of the ocean, lake or other water pools. Slowly this will build up until there’s only a thin layer of water or none at all.

One of the biggest issues that could happen is one of the biggest right now, Global Warming. They say that since the ice is white and can reflect sunlight this will bounce back up and therefore will create the earth to warm up by trapping the heat inside.

Another reason was that other life forms would die because there is no water in the ocean that means that not much water could be evaporated resolving in little rain which would give a huge drought and destroy nearly all plant life and not enough for us to live.

If ice was heavier than water then this can boost natural disasters and most commonly tsunamis and volcanic eruptions from the ice disturbing the volcanos (including underwater ones).

This could even affect the smaller things like if you were making and ice cold drink and it sinks to the bottom, suddenly your drink is now all warm on the top and cold on the bottom.

Now I hopefully have given you some ideas of what could happen if ice was heavier than water. Some of these could be incorrect or countered by other things, but there is one thing that could save us if this happens, we could be able to adapt and evolve to these climates and disadvantages.

If ice was heavier than water it could lead to many problems like; accelerating global warming, making nearly every life-form to die, increasing the likelihood of natural disasters, long term damage and finally your ice cold drink ruined.

So certainly no, humans will not be able to live on this planet even though we could adapt, this would take a very long time. And finally, I hope you know a few things that could happen `if water got heavier when it froze`.
