Proposal
Bacteriophages are microorganisms that are referred to as a virus. Bacteriophages were discovered in 1915 by two independent scientists, Frederick W. Twort and Félix d’Hérelle. Surprising thing is, Bacteriophages hunt bacteria in a pack which means they have different roles in the pack. When they are hunting they take the acid inside their heads and injects it into the bacteria making a replica of itself, killing its host as a consequence.
A bacteriophage’s anatomy consists of 4 body parts, the head (50x100nm) the tail, (10x100nm), the endplate (50x25nm) and the legs(100nm in length). To scale this, I will be scaling it up by using the ratio, 20nm: 0.5in / 40mn:1inch
To make a model, I will be using cardboard to make the triangular and construction paper to make the circular/cylinder areas.
Topic
For my project, I choose to do a bacteriophage, a virus which hunts bacteria in a pack.
Like many animal species, the pack has different roles. They kill bacteria by injecting a string/solution from their head into the bacteria and making the bacteria a replica of itself.
I wanted to scale something really small into a big model to make the project more interesting.
History
Bacteriophages were discovered in 1915 by two independent scientists, Frederick W. Twort (1915) and Félix d’Hérelle (1918). These are pictures of the scientists. The term bacteriophage, meaning “bacteria eater,” was named by D’Hérelle to describe the agent’s bactericidal ability.
Scale
A bacteriophage anatomy consists of 4 body parts, the head (50x100nm) the tail, (10x100nm), the endplate (50x25nm) and the legs(100 nm in length). I scaled it up by using the ratio: 20nm: 0.5in / 40nm:1 inch
Diagram
I first drew this diagram on paper to find the measurements and proportions.
Then I drew this to illustrate how the model would look like.
Building
The next picture is during the building process.
Final scaled model
This is the final model of a bacteriophage.
