Edible DNA

imageimage

1: genes are part of dna which is part of a chromosome
2: the red and black licorice are the backbones and the green marshmallow is Guanine, pink is Cytosine, yellow is Adenine, orange is Thymine
3: yes it did it gave me an idea of how dna is built

Oslam Syndrome, also known as Osteosarcoma
Hi, I am just a cell, but I have been secreting a growth factor structurally related to a homodimer of PDGF A-chains which is OSLAM Syndrome or Osteosarcoma. Unfortunately, I have developed in the osteoblast cells that form bones. I commonly affect bones around the knees, but I can affect any bone within the body. my host will most likely need to be amputated. they might not be able to walk or carry objects that need two hands again.

I used questions like ‘what is olsam syndrome’ and after finding out its another name for osteosarcoma I asked ‘what causes osteosarcoma’ and ‘how does osteosarcoma affect the body.’
I used the Google scholar search becasue I new it would be factual and have professionally done websites. I got the picture from the Wikipedia page for Osteosarcoma.

Expanding Universe

In this lab we looked at how the universe is expanding by blowing a balloon up and measuring dots on the ball00n. As the balloon (or the universe) expands the dots (or galaxy’s) get farther and farther away from the other dots. I thought this activity was good because it showed a simple way of how the universe is expanding, but I am still curious about when the universe will stop expanding.

Types of Charge

Vinyl carries a negative charge when it rubs with wool, but neutral when it rubs with cotton. Although vinyl is neutral, acetate becomes positively charges when it rubs with cotton. When the positive and negative acetate come near, they attract, but if two positive acetates or two negative vinyls come close to each other, they repel. If the neutral vinyl and the charged vinyl come close, they also attract.

Compound Project

My chemical compound is Arsine and the chemical formula is AsH3.

Arsine’s physical properties are as follows: It’s colourless, the melting point is 117 degrees Celsius, and the boiling point is -62 degrees Celsius

Arsine’s chemical properties: Arsine will react violently in presence of strong oxidizing agents. If mixed with halogens and some of there compounds, is extremely dangerous and can result in explosions.

Arsine was used for chemical warfare during WWII but now is exclusively used in semiconductor manufacturing.

The person who discovered Arsine was named Carl Scheele.

Oobleck Lab

The properties of chemical A and chemical B are very different. Chemical A (cornstarch) is a white powder, while chemical B (water) is a clear liquid. The properties of Oobleck are very strange. It is like a white liquid, but when force is applied to it, it hardens and becomes a solid. Oobleck is a liquid that turns into a liquid upon impact with other objects. This lab helped me understand KMT more because it proved to me that these items are not restricted to being one only thing.
