Egg parachute experiment

Hello readers today I will be telling you about the parachute test that we had to do in science

HOPE YOU ENJOY!!!

Aim

We did this experiment so we could learn about the forces that go into play when something is falling, we were learning about how forces and mass properly works via making a parachute.

Research

when researching I mostly figured we needed a way for us to catch the air to create air resistance when the egg was falling, we then looked at many parachute designs and ended up making one that worked similar to a hot air balloon.

Method

  • We first did some research into how to catch the air
  • Then we did some research on multiple designs
  • Then I started making the padding for the cup our egg was going to be held in
  • Then we started working on the design for the parachute
  • Then we made some tweaks to make sure that we could minimise the weight on the parachute

Results

Our egg managed to not crack throughout the entire fall and we landed onto the floor successfully, However we didn’t drop the parachute properly and it couldn’t collect all the wind to create any resistance and so it couldn’t fall as slow as we wanted it to. It took us a total of 2.75 seconds for our parachute to fall and if we had done it properly we could have very well hit at least 4 seconds on our fall

Discussion

The reason that some of the other design’s fell faster or slower could just simply be the way the dropped it all the way to the design itself, some design’s had very little plastic in the design meaning that the air couldn’t catch properly and the air resistance just didn’t work like it could have, or the design wouldn’t have had enough rope to make sure the plastic wasn’t pulled to create an area where the air could be caught not allowing it to catch the air and simply making it fail.

Conclusion

Something I would change for next time wouldn’t actually be the design in any way and instead change the way we dropped the top of it so it was open and had the ability to catch the air in the plastic meaning there was very little air resistance that allowed for it to fall as slow as it could have.

My commitments

Hello readers today I am making a goal for me to follow during this term or more
HOPE YOU ENJOY!!

the goal that I want to follow is Passing the CAA’s that are coming up and get better sleep. To accomplish this I will be studying most nights and with the sleep I really just need to go to sleep earlier and there’s not much else I can do regarding that.

End of topic test – Science

Hello readers today I will be going over my entire term of work and all the topics I covered in the term

HOPE YOU ENJOY!!!

Dna (Deoxyribonucleic acid) is a fundamental Molecule that carries our genetic code which is basically our genetic instructions which shows us how we will grow, age and change, it decides what we will look like and how we will come out at the end, For example. Our DNA is what makes us look and act like how we do and its different for everyone. Inside of our DNA is gene which is a small part of it that targets one specific area as in our eyes or hair. Our gene is one specific area of our DNA targeting one area as well, whether that be hair, eyes, height or anything along those terms, For example. If our DNA is like a complete book then our gene is one specific chapter of that book. Our gene is usually chosen between two choices each gene called the allele’s. An allele is the choices that our body makes typically 2 between the father and mother’s traits and we have a chance to get either one though sometimes its very little for some of it, for example. If the gene is a instruction book to how we bake cookies then our alleles are the different variants as in chocolate cookies or normal cookies but instead its our light hair or dark hair instead of something along those lines. We inherit these alleles from both of our parents every time as they basically give part of their genetic code and we inherit either the fathers or mothers side. Inheriting can be near anything whether its looks, personality, smarts or even items all things can be inherited by family members and some times outside of family if its a person giving an item instead, for example. I inherited a lot of money from my father when he passed or I inherited my mothers green eyes but my fathers black hair. We inherit these alleles which can be put into this thing called a punnet square. Punnet squares are these table’s where the input the fathers genes on the top and the mothers genes on the side and laying out the alleles in that order they can list out the chance of the baby getting certain features from each parent essentially guessing what the baby has the highest chance of looking like, for example. The father has the alleles of Bb which has a dominant allele and the mother has the allele’s of aa which are both recessive allele’s when we lay this out on the punnet square,we will found out that the baby has a 25% chance of inheriting the mother’s blue eyes while it has a 75% chance for the father’s brown eyes. These alleles we put on a punnet square can actually create what we call natural selection say when a dog inherit’s the fathers long fur and the other puppy was to inherit the mothers short hair, the short hair pup wouldn’t survive in the cold climate and would eventually not make it to the age needed to reproduce while the pup with long hair would be able to and this is called natural selection.

Natural selection is when the animal with the least suited trait for surviving dies out and the one with the best suited for surviving manage to create offspring which slowly the animals traits will go towards the animals traits making them more likely to survive in where they are being raised, for example. The fathers traits were much better suited for the animals survival so only half of the off spring survived and it was the ones with his traits. However for such a process to happen the father has to live long enough first so that he can even reproduce. Reproduce is when a Female of the species and a Male of the species fall in love or in some cases don’t even fall in love just following instinct reproduce and create babies of the same species and either gender the amount of babies will always nearly vary between species and sometimes even between the same species the amount of offspring will be different as well and this process on repeat slowly causes an evolution. Evolution is when over hundreds of years the species traits become so different they can basically become an entire different species and at times they are counted as a new species, for example. Over the hundreds of years the wolf has been around for thousands of years slowly changing and becoming new species for example huskies which were once wolves but evolved over years and years to become the house pets they are today.

 

Goal reflection

Hello readers today I will be reflecting on my week of working towards my goal which is to pass all of my exams for this year…

HOPE YOU ENJOY!!!

This week I had 2 exams one for maths and one for english in the maths exam there was a little bit I forgot to revise and failed to do but I did the excellence question and I’m quite sure that I got it right as all my friends said they got the same answer I’m also studying quite often nearly every night when I’m not working out, with the English exam I’m pretty sure I’m getting a high grade as it was very easy for me to do and I didn’t struggle at all.

Reflection

Hello readers today I will be reflecting on my week of working towards my goal which is to pass all of my exams for this year…

The progress I have made towards my goal this week was making sure that I am focusing on my academic performance and making sure I complete every worksheet and piece of work that has come to me, in all of my classes. I have not had any exams this week so I have not made any major progress on my goal so far

Zombie genome

Hello readers today I will be showing you how I made a entire DNA code for a zombie

HOPE YOU ENJOY!!!

AIM

The aim of this experiment was for us to get confident using punnet squares and to master the aspects of using a punnet square and make sure that we understood how to

Method

We had to pick the parent genomes and create a zombie out of the genome and punnet squares. The different alleles for each thing was… Skin colour: S and s, Hair: H and h, Limb count: L and l, Clothing: C and c, Teeth: T and t, weapon: W and w. I decided the traits that my zombie had using a punnet square which is basically a square where you predict the chance for each allele to come out over the other allele.

Results

Discussion

The gene is composed of the dna’s sequence… Allele is one or two versions of a gene that is found in the chromosome… genotype is the actual DNA you come out with at the end of the day… phenotype what the person looks like compared to their genotype as they might have pasty skin but tanned so they have darker skin that would be their phenotype… to fill out a punnet square you put the fathers alleles at the top 2 and the mothers alleles on the side 2 boxes then you bring the fathers alleles down 2 boxes and the mothers alleles across 2 boxes making 4 different combos for the possible gene finding the most possible gene, the point of this is to predict the actual gene or get an idea on what the baby will look like…

Conclusion

The punnet squares did work and I don’t think I would change anything for the next time we do this

Drawing Challenge

Hello readers today we did a drawing challenge in health. We had to have 2 people 1 of us explaining the picture and the other drawing it.

HOPE YOU ENJOY!!!

 

What was the activity

The activity that we took part in was the Drawing in pairs challenge, The way we do this is have one person sit back to back with another person and they get handed a picture that they have to explain the drawing bit by bit, while the person on the other side of the chair had to draw what he heard from his teammate to try get the drawing as close to the original as possible.

What Hauora were effected in this game

In this game the Hauora that was effected was our social side as we had to communicate cleanly and make sure each other understand, it worked this area because we had to understand what it sounded like for the other teammate/person from there end.

Did our values get shown

Yes our values got shown in today’s work as we didn’t discriminate everyone got included and no one was without a partner the fairness was there as we did swap roles eventually so yes I think our values were shown quite well.

How well did I participate

I Participated quite well in this task, I explained made sure I made sense and when it came to the drawing turn for me I listened as close as I could, in this I showed my values very well because I included my teammate didn’t discriminate his bad drawings and explaining skills and I also was quite fair with all the other participants as well

What are the definitions of the concepts

Short term = the short term means something that doesn’t last very long compared to other things that happen all around

Long term = the long term means something that lasts a long time specifically ranging 9 months to 12 months/1 year

Social justice = A fair thing where everyone has the same opportunities as everyone else in their environment

Consequence = consequences are a real thing that means when you do something wrong there will always be something like a repercussion or something to punish your actions

 

Building a whare

Hello readers today I will be talking about my last lesson in health focusing on the areas of our hauora and the whare that we made…
HOPE YOU ENJOY!!!

Activity

We built a whare out of 6 pieces of paper and named the walls after each area of the hauora, being mental/emotional, physical, spiritual, social. We took place in this activity by building the whare with the 6 pieces of paper in a stable way so that it doesn’t fall, the rules were just to build a whare and have it stable and standing with the play dough as some cool designs to represent each area of the Hauora/walls.

What areas of Hauora

The areas that were effected were the social side of things as me and my group had to work together to get the project done, and a little bit of mental and emotional cause when the building fell and we had to use calm our self after working on it for so long.

how were the effected

They mental and emotional was effected because of the strain it had emotionally whenever a part or the entire thing fell over and our social because us as a group had to come up with ways to build the whare together find out what worked and what didn’t

What values were shown

The many values that were shown include inclusiveness and this is because of the fact that they had to let everyone talk with each other and share their own ideas then let everyone come to an agreement on one specific idea and yet use everyone’s ideas to make sure no one was left out that was the key value shown in this project but for short their were things such as fairness,social justice and more

How did I do

I feel that I did very good at this activity as I did around half the work In a group of about 3 people and included everyone’s ideas and even made our own original building.

This was our house we made

Dna Extraction

Hello readers today I will be going over my recent science experiment when we extracted some Dna from strawberry’s …

HOPE YOU ENJOY!!!

Aim

The aim of today’s experiment is to Extract the DNA from a strawberry so we could see what it looks like, and so we could learn the ways of the lab for the class…

Method

The method For the DNA extraction from the strawberry went like this, 1st step we grabbed some strawberry’s and put it into a plastic bag second step we put some dish soap into the bag on top of the strawberry’s, we then put some salt on top of the strawberry’s then finally we put some water into the bag and made sure to zip up the plastic bag tightly and then start mushing constantly to make sure its at least part liquid. Then we Poured the mushed strawberry’s into a cloth over a beaker the partly mushed strawberry draining through the cloth to make sure that the liquid was no longer full of mush. Then we grabbed the breaker and poured the liquid into a test tube where we let it sit for about 5 minutes before we poured ice cold ethanol into the test tube on top of the strawberry liquid we then mixed for about a minute then sticking a pipette into the test tube which we picked the DNA up with.

Discussion

2 things I learnt from this experiment is that its possible to extract DNA from a strawberry this shocked me because I thought DNA was to small for the eye to see yet we could see it when we did this method what I want to know if its doable with other fruits and vegetables such as Brussels sprout or apples as that would be cool, the second thing I learnt is how to extract DNA from fruits, this method and way of doing it was something I did not expect…

When we extract DNA from saliva, blood and plenty of other things we can test the genetic for mutations and disorders to identify any disorders in the DNA, they do this with machines, such as centrifuges, homogenises and a couple other machines the machines, the centrifuge spins the sample at high speed using centrifugal force to separate the components of the sample.

Evaluation

The experiment worked well in my eyes because of the clear set of instructions we had to follow. One thing that I think went well was our straining speed as it went by very fast and effectively. one thing we could have done better in my eyes would be something like the amount of liquid we got out from the straining something we could have done to make it more effective was maybe get more mushing of the strawberry’s in before we put it on the cloth or get more water into the plastic bag as this could have made for a better proportions of liquid

science animation ASSESMENT

Hello readers today I am doing an animation on the moon formation using the giant impact theory…

HOPE YOU ENJOY!!!

Theory…

the giant moon formation is a theory where a Mars sized body came in impact with the proto-earth the earth at this time was a little bigger than the mars named body called theia, Theia had entered the Proto Earth’s atmosphere and was being caught by earths gravity though theia had done the same and was dragging earth as well each one caught by each other. eventually they made impact and theia obliterated earths side and created a ring of debris the earth sucked in all the left over pieces of theia making earth bigger again though by now the proto earth had a ring of debris from the impact. eventually the big piece of theia that was left made impact again and again until theia’s gravity was no longer enough and earth sucked up the debris surrounding while making the former theia its new moon and so that’s how the moon came about.

Evidence…

The evidence behind this Theory is that the moon and earth of today’s age have a similar rock surface of each other, which makes the impact theory more possible because they most likely traded rock when they were crashing into each other, we know this because there were missions sent out one of them being Apollo had been tasked with bringing back the rock on the moon back to earth and when they tested the rock it came out to be very similar.

What was proto earth?…

The proto earth was a early molten version of our earth that existed a total of 4.5 billion years. The impact with theia dramatically changed the planets chemistry by a huge amount. It changed by melting its internal body and making the current earth out of its left over debris.

Slide description…

On my slide I show the events and even how the earth changes after the moon is formed first I show the proto earth and theia pulling each other close together than I show the 2 impacts and the formation of the moon before the transformation of the earth. Here is the slideshow animation that I have done.

What theory is most likely?…

The most likely theory is the one that I have mentioned in this blog post I believe this because this theory has much more evidence than all the other theory’s that have been concluded there are 3 that stand out but this one rises above the other ones for the most evidence and logic following
