Rube Goldberg Project

1. First, we drop the marble into a cut in flag pool noodle. The marble then goes almost straight down and then it curves up and falls on to the next pool noodle. This noodle then drops the marble onto a slanted piece of cardboard which guides the marble on to another set of pool noodles. The noodles roll the marble across the back wall and drops the marble into a tube which then rolls the marble down and dings the bell.

2. Point A starts with potential energy and transfers to Kinetic around point B. Point B-C goes from kinetic to potential as the marble falls, at point d the energy goes back to potential as the marble falls,F-G and G-H are examples of kinetic to potential as the marble falls. H-I is kinetic to potential as the marble stops, and kinetic to sound as the marble hits the bell.

Making Babies!

Duayne had a square face and a very prominent round cleft chin. He also had medium brown skin and very dark curly hair with a widow peak. Duayne had very dark bushy eyebrows that weren’t connected and brown almond eyes. He has a medium nose and has Darwin’s ear points as well as forehead and cheek freckles. He’s honestly a tad ugly but you can expect anything very nice coming from Josh and I.

Answer the following questions:
A. How does the coin flip relate to the probability of inheriting genetic conditions?
Because there is a 50% chance your get one of the 2 alleles from your mother and a 50% chance you get another one of the 2 allele from your father.
B. How does this simulation accurately represent or not represent real life?
This inaccurately represents your life because it was chosen traits and wasn’t reflective of how a real life baby would inherit the traits of their parents
C. Did you identify any prejudices you might have about what traits you find “desirable”? Where do you think these prejudices come from
Yes, I think by seeing the choices that we could get for our baby we were very focused on making sure the baby wasn’t ‘ugly’. I think this comes from being able to see the options and knowing typically ‘beautiful’ standards and just wanting the baby to look nice.

Float Your Boat

In this experiment we were put into groups of 4 and were given around 10 minutes to construct a boat of out one 20cmx15cm piece of aluminum foil, 15cm of masking tape, 2 toothpicks, and 2 marshmallows. This boat had to be able to float as well as hold the weight of as many pennies as possible.

Hypothesis: If we build an origami boat out of tinfoil then it will hold up will in the water and it will float because it mocks a boat. By putting the pennies in the middle the weight should disperse evenly.

Conclusion: When we conducted the experiment we discovered that our boat was only able to hold 12 pennies before sinking which disproved out hypothesis. If we had used all of the tape we were given instead of only a majority of it then that may have helped our boat from sinking. To improve the experiment we should have chosen a better design for the boat so it wouldn’t get too heavy all at one point and pull the boat down.
