Rube Goldberg Project

Overall Photo:Drawing of Our Machine:

My Partner and I’s machine is called Beep Bop and the task of our machine was originally to pop a balloon but sadly that did not turn out, so we replaced the balloon with a bell, which that worked. Our new task was to ring a bell.

Steps to Our Machine:

  • First, our Lego car rolls down a ramp (Part A) then hits a few dominoes and then the dominoes hit a small marble.
  • Second, once the dominoes hit the small marble, the marble will roll down a foam tube then through a tunnel and hit more dominoes (Part B).
  • Third, after the small marble hits the dominoes, the dominoes will hit a medium sized marble down a ramp, then the marble will go around a corner (Part C).
  • Fourth, after the marble goes around the corner it will reach the end of the table and fall through a tube (Part D).
  • Lastly, when the marble falls through the tube it will land on a bell and ring it (Part E).

Energy Transfers:

  • When the car is sitting at the top of the ramp its potential energy but than when the car goes down the ramp its kinetic energy (Part A).
  • When the dominoes are hit by the smaller marble and start going off, that is kinetic motion energy and when the dominoes hit the bigger marble, it begins to roll down the ramp, which is also kinetic motion energy. (Part C)
  • At part D when the marble reaches the end of the table and falls through a tube, that is kinetic energy.
  • Once the marble rings the bell, the marble will begin to have potential energy because the marble will not be moving. (Part E)

Making Babies- Science 10

Ellie Marie Violet Yellow

 

Question 1: Include a short description of the traits your child has.

My partner and I decided to name our little baby girl Ellie Marie Violet Yellow.  Ellie has a square face, and a very prominent square shaped chin. She has wavy hair, large almond shaped brown eyes and bushy connected medium dark eyebrows.  She has an average sized mouth, with thick lips and dimples.  She also has round ears that are a bit hairy. Lastly, Ellie has some freckles all over her cheeks but not on her forehead

Question 2: How does the coin flip relate to the probability of inheriting genetic conditions?

Answer: Depending on whether the coin landed on heads which is the dominant side, or it landed on tails which is the recessive side. The coin was randomly flipped, and this represented the genetics being passed down from each parent.

Question 3: How does this simulation accurately represent or not represent real life?

Answer: This simulation does not represent real life because if both parents had blue eyes than their child would probably have blue eyes and not a different color. A coin flip does not decide the traits that a baby could have.

Question 4: Did you identify any prejudices you might have about what traits you find “desirable”? Where do you think these prejudices come from?

Answer: In my opinion I think the prejudices come from the media and the people around us. I also think that everyone is beautiful in their own unique way. Some might not be beautiful at the beginning, but everyone will become beautiful later on and will learn to love something and see what they value the most.

 

Classifying Reactions- Science 10

 

 

 

 

 

 

 

In this assignment we were supposed to create four chemical reaction analogies using the four types of reactions, which are synthesis, decomposition, single replacement, and double replacement.

 We had to show all four basic laws for each reaction, also, a real-life example using real elements and then we had to balance the equation out. This assignment helped me with balancing out equations and made me understand more of what we are doing in Chemistry 10.

Float Your Boat- Ainsley

 

Today in my Science 10 Class, our teacher Ms. Kim told us that we are doing an experiment called “Float Your Boat.”  We had to work in a group of 3-4 people and the only materials that we had were 1 piece of aluminum foil, 1 piece of masking tape, 2 toothpicks and 2 marshmallows. Our hypothesis was that If we double the tin foil (fold it over twice) then the boat will be able to hold more pennies because it would be sturdier.

After, we had 15 minutes to brainstorm and design our boat, my group had looked at multiple ideas online. Once we were done making our boat, we went and tested it out, by placing the boat into the “pond.” While our boat was floating I was excited, although I was nervous too because I was afraid that our boat would sink right away.

In conclusion, our hypothesis was correct. The reason why it was correct is because we doubled the tinfoil by folding it over to make it thicker, which would make it studier, that is why our boat held 48 pennies and our group came second place out of 6 other groups.

Observations

Qualitative Quantitative
Silver Color Held 48 pennies

The opposite corners of the boat folded in-wards because of the weight of the pennies.
