Parallax is when there is apparent displacement of an object because of a change in the point of view. scientists use this method to measure the distance between stars. As the earth orbits around the sun the closest stars appear to move backgrounds amongst other stars. Scientists measure the star once and then six months later. After they take the data and measure the difference.
In this experiment, I had to make a model of a DNA using liquorice, different coloured marshmallows, and toothpicks. The liquorice represents the double helix. The backbones of the DNA are made up of sugar and phosphate. The different coloured marshmallows in the photo represents the bases which are adenine (yellow marshmallow), thymine (orange marshmallow), guanine (green marshmallow), and cytosine (pink marshmallow). The rungs or base are always bonded in a certain way, adenine (A) double bonds with thymine (T) and cytosine (C) triple bonds with guanine (G). This activity gave me a better understanding of DNA. Matching the bases helped me remember their names, letters, and also their pairings and also gave me a general idea of what DNA looks like.
I had to make a DNA bracelet. Each coloured cereal represents a combined base letter to make it into a codon. Green = adenine, purple= guanine, yellow = thymine, and pink = cytosine. The 3 pieces of cereal makes it a letter in the alphabet of the DNA alias code. The entire message of the bracelet represents the DNA sequence. My name is representing the multiple codons which make up amino acids.

1.
Chemical A: A white, powdery, solid (corn starch)
Chemical B: A yellow colored liquid

Oobleck was white and gooey. It was also a physical change since the powder and liquid combined changed it into a solid/liquid goo.
3.
I think that the oobleck was a solid and liquid, it all just mattered on how much liquid was put in it and also where it was. If it was on the table sitting it would turn hard and dry but when u would hold it in your hand you could see that the top of it looked wet so it was a liquid.

Oobleck helped me see how physical change works and also how it could be 2 states at the same time, having both properties of a solid and liquid.
Ammeter 1= 220
Ammeter 2= 220
Bulb 1= 1.2
Bulb 2= 1.1
Battery= 3.0
The current stayed the same in ammeter 1 and 2. The voltage in the bulbs are different by 0.1. The voltage of bulb 1 and 2 combined are different to the batteries voltage by 0.7. The current and voltage change depending on how many ammeters or voltmeters there is.
The way that my group found it to create the brightest light with the circuit was by connecting both wires to the light and the wires that were from the battery to the wires connected to the light, therefore creating a full circuit. I learned that the strength of the wires really matters for how light the light bulb goes because if it isnt as powerful then the light bull will barely shine, but if they are then the light should shine bright unless there is a different problem in the circuit.
I learned lots from experimenting with the Van De Graaf. I learned that it was able to bend water and pick up materials. I found it interesting on how we were able to make a human chain and it could shock people.
The combination that worked best was the white plastic stick and fur. We were able to make one full rotation and I learned how friction causes static electricity.
I find it weird how whatever you do on the Internet is being traced and whatever you do is going to remain there and someone is always gonna have it even if you delete it. I will from now on be sure to realize what I am searching because I do not want something bad come back to my name that anyone could see.
The Europeans have came over to the First Nations land and have made contact and settled in. Although Europe’s contact and settlement positively impacted the First Nations in some ways, there were too many negatives therefore the Europeans contact and settlement negatively impacted the First Nations.
Europe has made some positive impacts on the First Nations. They provided them with guns so they can have an advantage in a fight over there opponent and can use it for easier hunting. They also attempted to civilize the First Nations and convert them to Catholics. This is showing them a new religion and new ways to see in life. The First Nations are also lucky to have the Europeans supplying them with goods made out of iron, such as tools and cooking utensils. That was giving them ways to do things they already had to do faster, such as cooking. The Europeans and First Nations also created an alliance for wars to be able to out number there opposition for the upper hand. There had been a disease going around called scurvy so they had created a medicine for it that was able to help it so less people would die from the disease. Both the Europeans and First Nations created a group called the Metis. It started up a new culture and made the two get along with each other. Europe should be recognized for the positive impacts that they made with the First Nations.
Europe’s contact and settlement has also negatively impacted the First Nations. They had supplied the First Nations with both guns and alcohol which can be a good thing. The only problem is that not everyone had got guns so it was unfair. They would also be wasting valuables that they could’ve traded for something productive, but instead they got it for alcohol. Alcohol would just get them drunk and not be able to work. While the European’s were trying to “civilize” the First Nations and make them Catholics, they were not being reasonable. They were basically forcing them into believing what they believed in and would not give them a choice even if what they’re forcing them into is out of there comfort zone. They also supplied the First Nations with the tools and cooking utensils which is a good thing. The only bad part about it is that they were having to trade for the items, so they were not free. The solution they had when they could not agree over something was to have a war between each other so people were being killed when they were supposed to be fighting wars with each other, not against each other. There were also plenty of people that were getting a disease called scurvy from being on the boats and coming over which many people had died from. Also the French had just came in and took over the land without even paying the First Nations. The Europeans settlement was very negative and could’ve been a lot better.
To sum it all up there would be too many negatives between the First Nations and Europeans to say that there settlement positively impacted the First Nations. Although Europe’s contact and settlement positively impacted the First Nations in some ways, there were too many negatives therefore the Europeans contact and settlement negatively impacted the First Nations. If only the Europeans could have been a little bit smarter on there decisions to make it a successful impact.
