Science 9

In science Honours 9 we created a video to demonstrated Meosis.

In my science class, we were assigned to research a cell and write a story based on their perspective.

Hello! Greetings from the inside of the human body, also known as my host, Claire. Now, you may be wondering what’s my name?, and what am I? Well, I’m known around here as Melanocyte, and most people call me Mel. My job is to make you look like you. I have many locations with many cells that are just like me. I’m mainly located in the deepest layer of skin, the epidermis, you can also find me in hair follicles and the middle layer in your eye know as the uvea. 

I have many responsibilities, my friends and I have the job of distributing melanin, which is pigmentation. So the reason why you may never tan or just seem to gain a perfect natural glow over the summer is all thanks to me. My primary function is to pigment your distinct features on your body, your skin, eyes, hair, etc. So, when do we occur? Primitive melanocytes first appear in the skin during the eighth week of fetal life, but at that time they produce little melanin. Only after you are born normal melanocyte cells begin to function in the right matter. In the skin, I form a bond with the keratinocytes which are the cells that make your hair. So, what do I look like? Well, I’m not a super fancy cell, I’m on the primitive side. I have a nucleus and other organelles such as Phaemelanosomes, eumelanosomes, Eumelansomes. Cells like me can have plenty of friends or little depending on their host’s genetics.

What questions did you need to research in order to research your topic?

• What does the cell look like?
• Where is it located?
• Is this cell’s role necessary?
• Are there any consequences to your body if the cell is not in the body?
• what is the primary function of the cell?
• does my cell use other cells to do its job?

what digital tools did I use to create this project?

• Gale Engage Learning
• EBSCO Host
• Science in Context
• google scholar
• science Direct

what was the process I used to investigate my topic?

• Asked questions about the cell.
• Acquired Information about the cells.
• Analyzed Information collected to verify legibility.
• Applied information to answer questions.
• Assessed information to create cell story.

how did I verify my information I found

I read a various number of articles on the school proofed websites to check if the information was consistent and made sense. I also researched other websites found on google to check for consistency.

How did the process of completing this challenge go? What could you have done better?

I found this project to be quite straightforward and very understandable. The library research resources made it much easier to find information and learn about my cell. Nextime, I could’ve spent more time and go into more depth but due to personal circumstances, I wasn’t able to in that amount of time. I spent a large amount of time researching and not enough time writing my story. overall, this was a pretty understandable project for me in my perspective.

In science honours 9 I created a sway presentation to demonstrate my learning of an inquiry project. Hope you enjoy!

how does electricity impact our hearts?

our hearts are the organs inside of our chests that help keep us alive. The contraction pumps blood through the circulatory system to keep the rest of our bodies healthy and happy. The only…

define; In my science class we were given the experiment to find what painkiller worked the best out of the following medications; Advil liquid gel, Asprin, Tylenol, No name Life brand capsule, and Motrin. we were intrigued by the Advil liquid gel because this medication failed to dissolve in past attempts even though test subject(Mr. Hortons son) speaks highly of this medication when wanting to be relieved from migraines. In our experiment, we were to make a stomach like an environment to create a more realistic environment for the pills to dissolve.

Discover;

1. what is the gasteric fluid made of?
2. what are the most important components of the stomach enviorment?
3. what can we use to represent this?
4. what is the process the pill goes through to dissolve in our bodies?

                                       

above are the pills that we used.

We wanted to try and make a liquid that would be similar to a human stomach. We had to find out how warm our stomach is and find out acid that would mimic the acid in the stomach.We found out that the stomach is around 37 degrees Celsius so we heated our test tubes on a hot plate and we used pure white vinegar and mimic the acid. our stomach like concoction was our controlled variable, the pills were the independent variable.

we decided to add some movement by tapping the test tubes to make a current, to represent the movement of the process of dissolvement in our bodies.

results

we found out that the aspirin pill dissolved first, a powdery cloudy substance compacted to the bottom. we also found out that even though we created a more stomach like concoction the advil liquid gel pill still failed to have a big effect.

pill	time	Results
Tylenol	31 minutes>	Looks like white fuzz
Advil Liquid gel	31 minutes>	Looks like expanding; letters peeled off not much change.
Asprin	31 minutes>	looks like a small gathered fuzz at bottom of test tube.
Motrin	31 minutes>	A flattening pancake…starting to get fuzzy.
Life brand	31 minutes>	exploding like the capsule broke open ‘fluff’ is coming
tylenol	26 minutes >	Thich layer of fuzz
Advil	26 minutes >	Looks the same
Asprin	26 minutes >	Small amount of fuzz
Motrin	26 minutes >	Looks like it is rising
Life brand	26 minutes >	Breaking apart the capsule
Tylenol	20  mins>	Fuzz is expanding
Advil	20  mins>	There’s a faint line separating the outer layer
Asprin	20  mins>	Looks the same
Motrin	20  mins>	Fuzz; rising up
Life brand	20  mins>	Mix of red and white
tylenol	15 min>	Looks the same
Advil liquid	15 min>	top is wider than the bottom
Asprin	15 min>	Looks the same
Motrin	15 min>	looks the same
Life brand	5min>	Looks like blood and snow
Tylenol	5min>	Still is fuzz
Advil	5min>	Still bean like milky liquid is releasing from crack
Asprin	5min>	Looks the same
Motrin	5min>	Looks the same
Life brand	5min>	Looks the same

in conclusion, the aspirin pill dissolved into a white powder at the bottom of the test tube at the fastest speed at the small amount of time of 60 seconds. the Advil got its results last of the medications.

 

debrief:

Overall, this experiment was very successful even though we didn’t receive the results that we had hoped for. We were able to create concoctions that almost resembled a stomach like enviorment, and we were able to dissolve most of the pills. with further research and testing one day I would hope that we will be able to fully dissolve the Advil liquid gel. during this testing, I believe that we should add a stronger acidic liquid to more realistically represent the stomach acid. In other testing, I also believe that we should add more movement really recreating the movement of the process inside. like said above the Advil liquid gel generally needs more exploring to get better results. I’m very grateful for this experiment because I got to really learn about the medications I have taken or will take in my lifetime. in conclusion the experiment was well planned and thought out with no major problems along the way.

In my science honours class we were intreaged to see which medication dissolves the quickest in a stomach like enviormnet.
