For our thermos we managed the least amount of heat in 45 min, Our price range had to fall under 3$. We created 3 prototypes to experiment on. We agreed that prototype number 3 was the best prototype Although it came to 3.68$. We used 10 inches of tin foil, 2.5 styrofoam cups, 2.5 inches of foam underlay, and 5 inches of tape. Prototype 3 was successful we lost 26 degrees celsius in 45 minutes. The first 2 prototypes that we created lost a substantial amount of heat in only 20 min so those were busts. There were 3 designs we had planned out the first two prototypes were created without lids that why they lost the heat because there was no lid to trap the steam and the excess thermal energy inside the cup.

How do the laws of physics as we know them change as we travel throughout space?
The universe is guided by the laws of physics that we as humans have recently discovered. There are many laws, but main laws that we see the most are the laws of motion, mass, and relativity. Without these laws, life would not be able to exist. Without mass, nothing would have a weight value, without motion nothing would be able to exist because all particles move at a rate which defines if they are a solid liquid or gas. There are many other laws that we follow but they all branch off of what we know to be the main laws
In space we know that there are fundamental laws like gravity and velocity, but what if there are laws that we don’t completely know about. What if there are laws of physics complexly different from what we know where there is a reversed gravity pulling you away from a massive object?
Newton’s laws of motion
- Motion- Everything that moves will continue to move unless a force is applied to stop its motion
- Inertia- If something of mass has motion applied to it depending on the mass of the object it will affect the change of speed and direction due to momentum.
- Opposing action- For every action there is an opposite to reaction to counter affect the already moving object.
One thing that we know as the black hole defies every law of physics that we know. The only rule that applies to a black hole is the law of gravity which lets us know that there are an event horizon and a strong gravitational pull. A black hole in nature in an infinite curvature of space-time and compresses matter to an infinitesimal density. The event horizon is part of the black hole that nothing can escape, not even light, it has the ability to break down the molecular level of any sub-atomic particle. The light can be compressed to create what we do not know to be inside.
For my Rac, I chose to address someone by their name when I started talking to them. For example, when I woke up in the morning I said hey Jamie. The look on Jamie’s face showed that they seemed happy that someone used their name up front directly at them. It showed me that people take comfort in hearing their own name and it really makes the person feel happy. I felt way more confident in my communication skills and it made me feel like I was being very polite. When I started saying it more my cousin said that they noticed that they felt happier when I used their name they said they felt important and they started using it more as they wanted to try it out as well. Using peoples names before you introduce yourself could be very useful even when you are not trying to start a conversation. If you use someone’s name at a job interview or at a professional occasion it could show that you are a very mature person and want to set a good impression.
I really enjoyed this RAC and I think that I will start using it way more often throughout my day to day life.
When we took our orange we cut it in half to create a hemisphere. we took the insides of the orange out then ripped up the skin into little pieces so that it would fit into three circles with the same circumference as the orange. We found out that the entire surface area of the orange could fit into 4 squares. We came to the conclusion that the formula for the Surface Area is 4Pir^2
